PLEASE READ THESE TERMS OF SERVICE CAREFULLY. BY CREATING AN ACCOUNT, CLICKING "I AGREE," OR USING ANY PART OF THE OTTO SERVICE, YOU AGREE TO BE LEGALLY BOUND BY THESE TERMS. IF YOU DO NOT AGREE TO ALL OF THESE TERMS, YOU MAY NOT ACCESS OR USE THE SERVICE.
These Terms of Service ("Terms") constitute a legally binding agreement between you ("User," "you," or "your") and Otto ("we," "us," or "our"), the operator of the Service, governing your access to and use of the Otto AI assistant platform, including all associated software, APIs, websites, mobile applications, and services (collectively, the "Service").
Otto is operated by an individual in the United States, not by a company. Where these Terms refer to our officers, directors, employees or agents, they mean that person and anyone that person engages to help run the Service.
By (a) creating an account, (b) clicking any button indicating acceptance, (c) accessing or using the Service, or (d) otherwise manifesting your assent to these Terms, you represent that you have read, understood, and agree to be bound by these Terms and our Privacy Policy, which is incorporated herein by reference.
If you are accepting these Terms on behalf of a company or other legal entity, you represent that you have the authority to bind that entity to these Terms, in which case "you" refers to that entity.
You must be at least 18 years of age to use this Service. You confirm your age with its own checkbox when you agree to these Terms, and by using the Service you represent and warrant that you meet this age requirement. The Service is not offered to anyone under 18, with or without a parent or guardian, and we will close an account we learn belongs to someone under 18.
Otto is an AI-powered personal assistant that connects to third-party applications and services (such as Gmail, Google Calendar, Google Drive, Slack, Telegram, GitHub, and Linear) and performs tasks on your behalf through natural language interaction. Settings → Connections shows which services can be connected today; a service marked “Coming soon” there cannot be connected yet. Otto uses large language models (LLMs) and automated systems to understand requests and execute actions.
The Service includes, but is not limited to: email reading, drafting, and sending; calendar viewing, creation, and modification; task management; web research; document creation and editing; scheduled automations ("Routines"); memory storage and retrieval; integration management; and meeting attendance, recording, and transcription — including a notetaker that, at your direction, joins a Zoom, Google Meet, or Microsoft Teams meeting as a visible participant, records the audio, and produces a transcript (see Section 4, "Meeting recording").
We reserve the right to modify, suspend, or discontinue any feature of the Service at any time, with or without notice, without liability to you. We will use reasonable efforts to notify you of material changes.
Registration. To access the Service, you must create an account by providing accurate, current, and complete information including your name, email address, and a password. You agree to keep this information updated.
Account security. You are solely responsible for maintaining the confidentiality of your account credentials and for all activities that occur under your account. You agree to immediately notify us at team.ottohq@gmail.com of any unauthorized use of your account or any other breach of security. We will not be liable for any loss or damage arising from your failure to protect your credentials.
One account per person. You may not create multiple accounts to circumvent plan limits or bans. Accounts are non-transferable.
Account termination by you. You may delete your account at any time from Settings → Export & deletion. Deleting your account removes your data from Otto’s database straight away; copies can remain in our database backups for up to 60 days before they are purged, as the Privacy Policy describes. Deletion cannot be undone, so download your data first if you want a copy.
Deleting an account with a subscription. Deleting your account cancels any subscription immediately, not at the end of the billing period. The rest of the period you have already paid for is not refunded, except where the law requires it. If we cannot cancel the subscription with our payment processor at that moment, nothing is deleted and we tell you so, so that you are never left paying for an account that no longer exists.
You agree to use the Service only for lawful purposes and in accordance with these Terms. You agree not to:
Meeting recording. Otto's meeting features can record and transcribe conversations. When you send Otto's notetaker into a meeting, it joins as a visible participant named “Otto — Notetaker (recording)”, records audio only (never video), and speaks an announcement into the meeting stating that it is taking notes; that announcement is itself part of the recording. When someone joins later, Otto pauses the recording and tells them — out loud if the room has not yet heard the notice, otherwise by a message addressed to them in the meeting chat — before resuming. The announcement has gaps, which the Privacy Policy (§4, “What the notetaker does not guarantee”) sets out: the first moments after the notetaker is admitted, and up to about ninety seconds for someone who arrives just after a notice, may be recorded before that person has been told. You agree not to suppress, disable, mute, talk over in bad faith, or otherwise circumvent that announcement, and not to send the notetaker into any meeting you do not have the right to record. You are solely responsible for complying with all applicable recording and wiretap laws where you and the other participants are located — many jurisdictions require the consent of every participant before a conversation may be recorded, and Otto's announcement may not satisfy every jurisdiction's requirements on its own. By using the recording features you represent that you have obtained any consent the law requires. The notetaker is also subject to each meeting platform's own rules about bots and recording (Zoom, Google Meet, and Microsoft Teams each have them, and some organizations block outside notetakers entirely); you agree to comply with those rules, and Otto will not attempt to circumvent a platform's or an organization's restrictions on its behalf.
We reserve the right to investigate suspected violations and to suspend or terminate your account without notice if we determine, in our sole discretion, that you have violated these Terms.
Nature of AI outputs. Otto uses artificial intelligence and machine learning models that may produce outputs that are inaccurate, incomplete, outdated, biased, or otherwise unreliable. AI-generated content does not constitute professional advice of any kind.
Not professional advice. Nothing in the Service constitutes legal, medical, financial, tax, investment, psychological, or any other form of professional advice. You should not rely on Otto's outputs as a substitute for qualified professional consultation in any field.
How Otto sends on your behalf. Otto’s automatic features — inbox sorting, follow-up nudges, meeting follow-ups and routines — only prepare drafts and proposals; they never send a message to another person on their own. A message goes out only when you approve it (including a message you approved to send at a later time, which goes at that time), or when you ask Otto directly in a chat to send it with “Save emails as drafts” switched off in Settings → Privacy (it is on by default, and while it is on, a request to send saves a draft for you to approve instead). After you approve a send, Otto usually waits a few seconds and shows an Undo control; once that moment has passed and the message has gone, it cannot be recalled. Otto cannot make purchases or payments for you.
User responsibility for actions. YOU ARE SOLELY RESPONSIBLE FOR ALL ACTIONS TAKEN BY OTTO ON YOUR BEHALF. Before approving or asking Otto to send a message, delete data, schedule an event, or take any other consequential action, you agree to review and verify the intended action, including its recipients. Otto’s confirmation prompts are a safeguard, not a guarantee of accuracy.
No guarantee of results. We do not warrant that the Service will meet your specific requirements, that outputs will be accurate or complete, or that the Service will be uninterrupted, error-free, or secure.
Third-party AI models. The Service uses third-party AI providers to process your queries: Anthropic by default, and OpenRouter when you choose a model from another provider (available on plans that include the full model marketplace) or, for content that does not come from your Gmail or Calendar, as an automatic backup when Anthropic is unavailable. Your inputs may be transmitted to these providers in accordance with their terms of service and our Privacy Policy, which names every provider and what it receives.
OAuth connections. To provide its functionality, Otto requires you to grant it access to third-party services via OAuth 2.0 or similar authorization protocols. By connecting a third-party service, you authorize Otto to access and act upon that service on your behalf, within the scopes you grant.
Scope of access. We ask for the permissions Otto’s features need, and a provider may ask you to grant them together even if you use only some of those features. In particular, connecting Google currently grants Otto permission to read all of the files in your Google Drive, not only the ones Otto creates; Otto reads a file only to do what you asked, and the Privacy Policy (§3) explains how that access is being narrowed. Settings → Connections describes, in plain language, what Otto can read and what it can change for each connected service; the full technical permission list is shown on the provider's own consent screen when you connect.
Third-party terms. Your use of connected third-party services is governed by those services' own terms of service and privacy policies. We are not a party to those agreements and have no control over third-party services, their availability, accuracy, or data practices.
Revoking access. You may disconnect any third-party integration at any time from Settings → Connections, which will cause Otto to delete the stored access token and cease accessing that service.
No endorsement. Our integration with any third-party service does not constitute an endorsement of that service.
Google Services specifically. Otto's access to Google APIs is subject to Google's Terms of Service. Otto's use and transfer to any other app of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements.
Our IP. The Service and its original content, features, and functionality — including but not limited to software, code, design, logos, text, graphics, and trade secrets — are and will remain the exclusive property of Otto and its licensors. These are protected by copyright, trademark, patent, trade secret, and other laws.
Your content. You retain all ownership rights to data, text, files, and other content you provide to the Service ("Your Content"). You grant us a limited, non-exclusive, royalty-free, worldwide license to store, process, display, and transmit Your Content solely for the purpose of operating and providing the Service to you.
Feedback. If you provide us with feedback, suggestions, or ideas about the Service, you grant us an irrevocable, perpetual, royalty-free license to use such feedback for any purpose without obligation or compensation to you.
No training on your data. We do not use Your Content or your conversation data to train, fine-tune, or improve AI models — our own or anyone else's — without your explicit written consent, and we do not grant any third-party provider the right to train on Your Content. Where a third party processes Your Content on our behalf, the Privacy Policy (§4, §5) states what each one commits to: for example, Otto sends Deepgram a per-request training opt-out on every transcription request, and Recall.ai, which briefly holds meeting recordings made by Otto's notetaker, is restricted by its standard data-processing terms to processing recordings only to provide the service — not for its own purposes, and not to train models.
Accounts without a plan. We do not sell a free plan. An account that has never subscribed, or whose trial has ended without one, keeps access to everything Otto has already saved for it, keeps the connections and routines it already has, and keeps a small monthly allowance of credits. It cannot use the features we are billed for by the minute: sending Otto’s notetaker into a meeting, full meeting transcription with speaker names (including transcribing an uploaded recording), and having Otto read replies aloud. Meeting notes recorded in your browser still work in a basic mode, without speaker names, using your browser’s own speech recognition. Connecting more than one app, or adding a routine, needs a plan. We may modify or discontinue this state at any time with 30 days’ notice.
Paid plans. Paid plans are billed in advance on a monthly basis. All fees are stated in US dollars and are non-refundable except as required by law or as expressly stated herein. The plans are Starter at $29 per month, Pro at $49 per month, and Max at $99 per month.
Monthly allowances. Each plan includes a monthly allowance for the two things we are billed for by the minute: recording and transcribing meetings, and having Otto speak replies aloud. The allowance for your plan is stated in Settings and resets at midnight Coordinated Universal Time (UTC) at the start of the first day of each calendar month — in the Americas, that is the evening of the last day of the month before; unused allowance does not carry over and has no cash value. Otto checks the allowance when a recording or a spoken reply starts. A meeting that is already being recorded when the allowance runs out is not cut off: it is finished and its full length is counted, which can take that month’s use past the allowance. Once an allowance is used up, new recordings and spoken replies are refused for the rest of that month and Otto tells you so at the point you try to use them, except that a meeting recorded in your browser carries on in the basic mode described above. Everything else on your plan continues to work.
Founding-member rate. If you subscribe at the founding-member rate, you pay a discounted rate for your first four billing months: $10 per month if you reserved your founding place before October 1, 2026, and $15 per month otherwise. Which rate applies is determined by the date of your reservation. Beginning with your fifth billing month, the subscription renews at the then-current Pro price (currently $49 per month). Billing is recurring and continues until you cancel. You can cancel any time from Billing settings; cancellation takes effect at the end of the current billing period, and no further renewals are charged. Except where required by law, payments already made are not refunded. If a payment fails, we retry it; if it cannot be collected, the subscription lapses and the founding rate ends. The general price-change right below does not shorten your four-month founding window.
Automatic renewal. Subscriptions automatically renew at the end of each billing period unless you cancel before the renewal date. By subscribing, you authorize us (or our payment processor, Stripe) to charge your payment method for recurring fees. About three days before each renewal — and before the first charge at the end of a checkout trial — we email you the date and the amount, with a link to cancel.
Price changes. We may change our pricing with 30 days' advance notice. A price change does not shorten an in-progress four-month founding window; it applies to your subscription from the first renewal after that window ends. Your continued use of the Service after the price change takes effect constitutes acceptance of the new pricing.
Trial. Every new account receives a 14-day free trial when its email address is verified. No payment method is needed for it and nothing is ever charged for it. The trial is its own level of service, not a trial of a particular plan: it uses Claude models only and has its own, smaller allowances, which Settings shows. If you choose a plan while your trial is still running, that plan starts and is charged on the day you choose it, and the rest of your trial ends. A checkout trial — where a payment method is collected at the start and first charged when the trial ends, unless you cancel before then — is offered only to an account that has never had a trial, and cancelling during it costs nothing. If you do not subscribe, the account continues under “Accounts without a plan” above and nothing you have saved is deleted. There is one trial per account.
Credits. Every account, subscribed or not, includes a monthly allowance of credits, which is how we meter the cost of the AI work Otto does for you. A credit is a unit of that cost rather than a fixed number of requests, so a short answer consumes very few and a long research task consumes more; your current balance and usage are always visible in Settings. The allowance resets on the same UTC boundary as the monthly allowances above, and unused credits do not carry over. Credits have no cash value and are not refundable. If a request fails after Otto has already done the work — for example the model answers but a later step errors — the credits consumed by that work have been spent and are not automatically returned. If this happens in a way that looks wrong to you, contact us and we will look at the ledger and correct it.
Cancellation. You may cancel your subscription at any time from Settings → Billing. Cancellation takes effect at the end of the current billing period, and you will retain access to paid features until that date; until then you can resume the subscription from the same page. Cancelling during a checkout trial means you are never charged. We do not provide prorated refunds for unused portions of a billing period. When the period ends, the account continues under “Accounts without a plan” above: cancelling deletes nothing. To remove your data, delete your account as described in Section 3.
Changing plans. Switching between Starter, Pro and Max is not yet offered inside Otto. To change plans, contact us at team.ottohq@gmail.com.
Failed payments. If a payment fails, Settings → Billing says so and our payment processor retries the charge on its own schedule; you can update your card from the same page. Your paid features keep working while those retries run. If the payment still cannot be collected, the subscription ends and the account continues under “Accounts without a plan” above. Nothing you have saved is deleted because a payment failed.
Taxes. Prices do not include applicable taxes. You are responsible for all taxes, levies, or duties imposed by taxing authorities in connection with your use of the Service.
Our collection and use of your personal information is governed by our Privacy Policy, which is incorporated into these Terms by reference. By using the Service, you consent to our collection and use of your data as described in the Privacy Policy.
You represent and warrant that you have all necessary rights and consents to provide us with any data you share through the Service, and that your use of the Service does not violate any applicable privacy laws.
THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, OTTO AND ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, SUPPLIERS, AND LICENSORS EXPRESSLY DISCLAIM ALL WARRANTIES, INCLUDING BUT NOT LIMITED TO:
NO ADVICE OR INFORMATION, WHETHER ORAL OR WRITTEN, OBTAINED FROM US OR THROUGH THE SERVICE WILL CREATE ANY WARRANTY NOT EXPRESSLY STATED IN THESE TERMS.
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL OTTO, ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, SUPPLIERS, OR LICENSORS BE LIABLE FOR:
WHETHER BASED ON WARRANTY, CONTRACT, TORT (INCLUDING NEGLIGENCE), STRICT LIABILITY, OR ANY OTHER LEGAL THEORY, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
IN ANY CASE, OUR AGGREGATE LIABILITY TO YOU FOR ALL CLAIMS ARISING OUT OF OR RELATED TO THE SERVICE SHALL NOT EXCEED THE GREATER OF (A) THE TOTAL AMOUNT YOU PAID US IN THE TWELVE (12) MONTHS PRECEDING THE CLAIM, OR (B) FIFTY DOLLARS ($50.00).
SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OR LIMITATION OF LIABILITY FOR CONSEQUENTIAL OR INCIDENTAL DAMAGES, SO THE ABOVE LIMITATION MAY NOT APPLY TO YOU IN FULL.
You agree to defend, indemnify, and hold harmless Otto, its officers, directors, employees, contractors, agents, licensors, and suppliers from and against any claims, liabilities, damages, judgments, awards, losses, costs, expenses, or fees (including reasonable attorneys' fees) arising out of or relating to:
Informal resolution. Before initiating any formal legal proceeding, you agree to first contact us at team.ottohq@gmail.com and attempt to resolve the dispute informally. We will use good faith efforts to resolve the dispute within 30 days.
Binding arbitration. If informal resolution fails, any dispute, claim, or controversy arising out of or relating to these Terms or the Service (except as noted below) shall be resolved by binding arbitration administered by the American Arbitration Association ("AAA") under its Consumer Arbitration Rules. The arbitration shall be conducted in English, and the arbitrator's decision shall be final and binding.
Class action waiver. YOU AGREE THAT ANY CLAIMS MUST BE BROUGHT IN YOUR INDIVIDUAL CAPACITY, AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS, CONSOLIDATED, OR REPRESENTATIVE PROCEEDING. THE ARBITRATOR MAY NOT CONSOLIDATE MORE THAN ONE PERSON'S CLAIMS AND MAY NOT PRESIDE OVER ANY CLASS OR REPRESENTATIVE PROCEEDING.
Exceptions. Either party may seek injunctive or other equitable relief in any court of competent jurisdiction to prevent actual or threatened infringement, misappropriation, or violation of intellectual property rights. Small claims court actions are also exempt from arbitration.
Governing law. These Terms shall be governed by the laws of the State of Delaware, United States, without regard to its conflict of law provisions.
These Terms remain in effect as long as you use the Service. We may suspend or terminate your access immediately, without prior notice, for any of the following reasons:
Suspension. If we suspend your account, you are signed out everywhere and cannot sign in, and Otto stops acting for you: it sends nothing, runs no routines and does not act on messages you send it on Telegram, Slack or email. Your data is kept while the account is suspended. If you believe a suspension is a mistake, or you want your subscription cancelled while your account is suspended, write to team.ottohq@gmail.com.
Upon termination, your right to use the Service immediately ceases. Sections 5, 7, 9, 10, 11, 12, 13, 16, and 17 of these Terms survive termination, as does Section 8 for any amount owed before termination.
We reserve the right to modify these Terms at any time. When we make material changes we will show you the updated documents in the app and ask you to agree before you continue using Otto. The effective date at the top of this page always reflects the version currently in force. Non-material changes may take effect immediately upon posting.
Until you agree to an updated version, Otto holds the work it does for you on its own — your morning brief and other routines, inbox sorting and drafts, and its background checks — exactly as the Privacy Policy (§13) describes. Reminders you set yourself, messages you scheduled to send, and billing notices are not held.
If you do not agree to the modified Terms, you must stop using the Service, and you can download your data, cancel your plan, or delete your account from the screen that asks you to agree, without agreeing.
We maintain a version history of these Terms. Each time you agree — at sign-up and on every later version — we record which version you agreed to, the exact sentence you ticked, the time, your IP address and your browser’s user-agent. A newer agreement is added alongside the earlier ones, never in place of them.
We strive to make the Service available 24/7, but we do not guarantee uptime. The Service may be unavailable due to scheduled maintenance, unplanned outages, force majeure events, or factors outside our control. We are not liable for any losses or damages resulting from Service unavailability.
We may impose usage limits, throttling, or restrictions to maintain service quality for all users. Excessive use that materially impacts other users may result in temporary restrictions.
Entire agreement. These Terms, together with our Privacy Policy and any other policies or agreements expressly incorporated herein, constitute the entire agreement between you and Otto with respect to the Service and supersede all prior agreements, representations, and understandings.
Severability. If any provision of these Terms is found to be invalid, illegal, or unenforceable, the remaining provisions will continue in full force and effect.
Waiver. Our failure to enforce any right or provision of these Terms will not be considered a waiver of those rights. A waiver of any right or provision must be in writing and signed by an authorized representative of Otto.
No assignment. You may not assign or transfer these Terms or your rights hereunder without our prior written consent. We may assign these Terms without restriction.
Force majeure. We are not liable for any delay or failure to perform resulting from causes outside our reasonable control, including natural disasters, government actions, internet outages, or third-party service failures.
Electronic communications. By using the Service, you consent to receiving electronic communications from us. These communications may include notices about your account and information about the Service.
