Terms of Service

Effective: August 7, 2026 Last updated: August 7, 2026

These Terms of Service (the "Terms") are an agreement between you and A1Base Inc. ("A1Base," "we," "us," or "our"), the company that owns and operates StudyArena. They govern your use of https://studyarena.ai, StudyArena's model-comparison battles, chats, model and provider directories, leaderboards, account features, sharing features, and any other website or feature that links to these Terms (together, the "Service").

By using the Service you agree to these Terms. If you do not agree, do not use the Service.

Our Privacy Policy describes how we handle personal information and forms part of the arrangement between us.

We have tried to write these Terms in plain language. Where a heading or summary sentence is shorter than the section it introduces, the full section governs.

1. Who may use StudyArena

You must be at least 13 years old, or the higher minimum age required in your location for us to provide the Service to you without parental consent. If you are under the age of legal majority where you live, you may use the Service only with the permission of a parent or legal guardian, who agrees to these Terms on your behalf where the law requires it.

You may not use the Service if you are barred from doing so under applicable law, including US export-control and sanctions laws, or if we have previously suspended or removed you from the Service for breaking these Terms.

2. The Service

StudyArena lets you submit questions and files to AI models, compare their answers, vote for the best one, and build a public leaderboard from those votes. It includes blind model battles, named and agentic chats, tools that models can use to answer a request, model and provider directories, per-school and per-category statistics, and features for saving, organising, and sharing your work.

The core Service is free for students. We may add, change, or remove features, models, providers, and limits at any time; a model that is in the pool today may not be tomorrow. We may also offer paid plans with higher limits, as described in Section 8.

3. Accounts

You do not need an account to use StudyArena. When you use it without one, your work is attached to an anonymous session in your browser, as described in the Privacy Policy.

If you create an account, you sign in through a third-party provider (such as Google or Discord) or an emailed link. You agree to provide accurate information, to keep your sign-in method secure, and to maintain at most one account. You are responsible for activity on your account. Tell us at help@a1base.com if you believe your account has been accessed without your permission.

You can delete your account at any time from your account page. What deletion removes and what remains is described in the Privacy Policy.

4. Your content

You own your work. Prompts, questions, files, and other material you submit to the Service ("User Content") remain yours. We claim no ownership of it.

The permissions you give us. So that the Service can work, you grant A1Base a worldwide, non-exclusive, royalty-free license to:

  • host, store, reproduce, process, and display your User Content in order to operate the Service for you;
  • transmit your User Content to the AI providers involved in answering your request, as described in the Privacy Policy;
  • display shared snapshots of your work to the people you share them with, for as long as you keep the share link active;
  • record your votes and use them in model ratings and leaderboards; and
  • create, use, publish, and license statistics and results derived from User Content, votes, and outcomes that have been de-identified or aggregated so that they do not identify you.

The license for de-identified and aggregated results, and for votes already counted into ratings, is perpetual and irrevocable — a leaderboard position is built from thousands of votes and cannot be unwound one contribution at a time. The license to your identifiable User Content ends when that content is deleted from the Service, subject to the retention practices described in the Privacy Policy.

We do not use your User Content to train AI models of our own, and we do not sell content that identifies you.

Your responsibilities. You are responsible for your User Content. Only submit material you have the right to submit, and only include personal information about another person if you are authorized to share it. Do not upload confidential school records or private communications belonging to someone else.

Feedback. If you send us suggestions or feedback, we may use them without restriction or obligation to you.

5. AI models and outputs

The models on StudyArena are built and served by third parties. Their answers ("Outputs") are generated by systems that are probabilistic by nature: Outputs may be inaccurate, incomplete, outdated, or offensive, and the same question may produce different answers on different days.

  • As between you and A1Base, we claim no ownership of Outputs generated for you. A provider's own terms may affect your rights in Outputs from its models.
  • Outputs are not professional advice. They are not medical, legal, financial, or safety advice, and you should not rely on them as such.
  • Verify anything that matters — especially anything you hand in, publish, or act on.
  • Because multiple models receive the same prompt in a battle, substantially similar Outputs may be generated for other users who ask similar questions.

6. Academic integrity

StudyArena helps you study; it does not decide what counts as permitted help at your school or university. Rules on AI assistance differ between institutions, courses, and even assignments. You are responsible for knowing and following the academic-integrity rules that apply to you. Do not use the Service to cheat.

7. Votes and the leaderboard

The leaderboard is the whole point of the site, and it is only worth something if the votes are honest. You agree to:

  • vote for the answer you genuinely think is best;
  • not vote using scripts, bots, or automation;
  • not coordinate votes, create multiple accounts or sessions to vote repeatedly, or otherwise manipulate ratings; and
  • not attempt to identify which model is in which lane before voting, or to promote or demote any particular model — this applies with special force to anyone affiliated with an AI developer whose models appear in the arena.

We may discard votes, adjust ratings, and suspend accounts or sessions to protect the integrity of the leaderboard.

8. Paid plans

The core Service is free. We may offer paid plans with higher limits. If you buy one:

  • prices, billing periods, and included limits are shown at purchase, and payments are processed by Stripe — we never receive your card details;
  • subscriptions renew automatically until cancelled, and you can cancel at any time, with effect at the end of the current billing period;
  • except where the law requires otherwise, fees are non-refundable once a billing period has begun; and
  • we may change prices with notice, taking effect from your next billing period.

Voting and the leaderboard never go behind a paywall.

9. Acceptable use

You agree not to:

  • break the law, or use the Service to harm, harass, defame, or deceive others;
  • submit or generate material that is illegal, that sexualises minors, or that depicts a real person in a false or misleading way without their permission;
  • probe, scan, or test the vulnerability of the Service, evade rate limits or storage caps, or access data belonging to another user or session;
  • use scripts or automation to scrape the Service or send bulk requests, other than reasonable use of public pages by well-behaved crawlers;
  • reverse engineer or copy the Service, or use it to build a competing dataset of model outputs, except where the law grants you that right despite these Terms;
  • resell the Service or misrepresent your affiliation with us; or
  • upload malware or otherwise interfere with the operation of the Service.

We may investigate suspected violations and remove content, discard votes, or suspend access — for anonymous sessions and accounts alike — where we reasonably believe these Terms have been broken. Where appropriate, we may report unlawful activity to authorities.

10. Sharing

Creating a share link publishes a snapshot of your work: anyone with the link can read that snapshot and open any files included in it, and may copy what they can see. Only share work you have the right to share, and remove personal or confidential information first. You can revoke a share link at any time, but revocation cannot recall copies that were already made. Chat spaces, folders, tags, and study groups have their own audience settings, described in the Service; placing a chat in a space does not by itself publish that chat.

11. StudyArena's property

The Service itself — its software, design, directories, leaderboards, text, and trademarks — belongs to A1Base or its licensors and is protected by intellectual-property law. We grant you a limited, non-exclusive, non-transferable, revocable license to use the Service as these Terms allow. Public leaderboard data may be quoted with attribution to StudyArena; bulk extraction is governed by Section 9.

12. Copyright complaints

If you believe material on the Service infringes your copyright, email help@a1base.com with: your name and contact details; identification of the copyrighted work; the URL of the material you believe infringes it; a statement, under penalty of perjury, that you believe in good faith the use is not authorized and that your notice is accurate; and your physical or electronic signature. We will respond as required by applicable law, including the US Digital Millennium Copyright Act, and we may terminate the access of repeat infringers.

13. Third-party services

The Service depends on third parties — AI providers, authentication providers, hosting and payment infrastructure — and may link to third-party websites, including pages fetched by a model's tools during a chat. Those services belong to their operators, are governed by their own terms, and are not under our control. We are not responsible for them.

14. Termination

You may stop using the Service at any time and may delete your account whenever you like. We may suspend or terminate your access — including anonymous-session access — if you materially breach these Terms, if we are required to by law, or if we discontinue the Service; where reasonable, we will give you notice. On termination, the licenses you granted for de-identified and aggregate results and counted votes survive, along with any other section that by its nature should survive, including Sections 4, 5, 11, and 15 through 17.

15. Disclaimers

THE SERVICE AND ALL OUTPUTS ARE PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, ACCURACY, OR UNINTERRUPTED AVAILABILITY. THE SERVICE IS A FREE COMPARISON TOOL; IT MAY CHANGE, PAUSE, OR BREAK. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF CERTAIN WARRANTIES, SO SOME OF THESE EXCLUSIONS MAY NOT APPLY TO YOU.

16. Limitation of liability

TO THE FULLEST EXTENT PERMITTED BY LAW, A1BASE AND ITS OFFICERS, EMPLOYEES, AND SUPPLIERS WILL NOT BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, DATA, OR GOODWILL, ARISING FROM OR RELATING TO THE SERVICE OR OUTPUTS, EVEN IF ADVISED OF THE POSSIBILITY. OUR TOTAL LIABILITY FOR ALL CLAIMS RELATING TO THE SERVICE IS LIMITED TO THE GREATER OF ONE HUNDRED US DOLLARS (US$100) OR THE AMOUNTS YOU PAID US IN THE TWELVE MONTHS BEFORE THE CLAIM AROSE.

NOTHING IN THESE TERMS EXCLUDES OR LIMITS LIABILITY THAT CANNOT BE EXCLUDED OR LIMITED UNDER APPLICABLE LAW, INCLUDING LIABILITY FOR FRAUD OR FOR DEATH OR PERSONAL INJURY CAUSED BY NEGLIGENCE, OR AFFECTS STATUTORY CONSUMER RIGHTS THAT APPLY TO YOU.

17. Indemnification

To the extent permitted by applicable law, you agree to indemnify A1Base against third-party claims, and the reasonable costs of defending them, arising from your User Content, your misuse of the Service or Outputs, or your breach of these Terms. This obligation does not apply where you are a consumer in a jurisdiction that does not permit it.

18. Disputes and governing law

Talk to us first. Before starting any formal proceeding, email help@a1base.com with a description of the dispute. We will try to resolve it informally with you within sixty days.

Arbitration (US users). If we cannot, and you live in the United States, you and A1Base agree to resolve the dispute by binding individual arbitration administered by the American Arbitration Association under its Consumer Arbitration Rules, rather than in court, except that either party may bring an individual claim in small-claims court or seek an injunction for infringement or misuse of intellectual property. Arbitration takes place in your home county or remotely, and AAA rules govern costs. You and A1Base each waive the right to a jury trial and to participate in a class action. You may opt out of this arbitration agreement by emailing help@a1base.com within 30 days of first accepting these Terms, with your name and a statement that you opt out of arbitration; opting out does not affect the rest of these Terms.

Governing law. These Terms are governed by the laws of the State of Delaware, consistent with the US Federal Arbitration Act, without regard to conflict-of-laws rules — except that if you use the Service as a consumer, you keep the protection of any laws of your home jurisdiction that cannot be waived by agreement. Disputes not subject to arbitration will be brought in the state or federal courts located in Delaware, unless the law of your home jurisdiction requires otherwise.

19. Changes to these Terms

We may update these Terms as the Service, the law, or our practices change. We will post the updated version at this address and change the date at the top. If a change materially reduces your rights, we will provide additional notice through the Service or by email before it takes effect. Using the Service after a change takes effect means you accept the updated Terms; if you do not accept them, stop using the Service.

20. Everything else

These Terms and the Privacy Policy are the entire agreement between you and A1Base about the Service. If part of these Terms is found unenforceable, the rest stays in force. Our not enforcing a provision is not a waiver of it. You may not assign these Terms without our consent; we may assign them in connection with a merger, acquisition, or sale of assets. We are not responsible for delay or failure caused by events beyond our reasonable control. Notices and communications between us may be electronic.
