Fission AI, Inc. (“Fission AI,” “us,” “our” or “we”) makes OpenSpec. These Terms of Use (“Terms”) govern your use of our websites, software and services that link to these Terms (collectively, the “Services”). Certain features of the Services may be subject to additional guidelines or rules, which are incorporated into these Terms by reference.
By accessing or using the Services, or by clicking “I agree” (or a similar button or checkbox) when that option is presented to you, you agree to these Terms on behalf of yourself or the entity you represent, and you confirm that you have the authority to do so. You must be at least 18 years old to use the Services. If you do not agree to these Terms, please do not use the Services.
Open-source software. The OpenSpec command-line tool is licensed under the MIT License. These Terms do not limit your rights under that license or under the license of any other open-source component.
Accounts
Creating an account. Some features of the Services may require you to register for an account. When you register, you agree to provide accurate and complete information and to keep that information current. We may suspend or terminate your account as described below.
Account security. You are responsible for keeping your login credentials confidential and for all activity that occurs under your account. If you believe your account has been accessed without your authorization, please notify us immediately. We are not liable for any losses resulting from your failure to keep your credentials secure.

License. Subject to these Terms, we grant you a limited, non-exclusive, non-transferable, revocable license to access and use the Services for your own purposes or the internal purposes of the entity you represent.
Restrictions. You may not: (i) license, sell, rent, lease, transfer, assign, distribute or commercially exploit the Services; (ii) modify, create derivative works from, disassemble, reverse-compile or reverse-engineer any part of the Services; (iii) access the Services in order to build a similar or competing product or service; or (iv) copy, reproduce, distribute, republish, download, display, post or transmit any part of the Services except as expressly permitted by these Terms. All copyright and proprietary notices must be kept intact on any copies you are permitted to make.
Changes to the Services. We may modify, suspend or discontinue the Services (or any part of them) at any time, with or without notice. We are not liable to you or any third party for any such modification, suspension or discontinuation.
No support obligation. We have no obligation to provide you with support or maintenance for the Services.
Ownership. All intellectual property rights in the Services, including copyrights, patents, trademarks and trade secrets, belong to Fission AI or its suppliers. These Terms do not transfer any ownership rights to you. All rights not expressly granted are reserved.
Your content. You keep all rights in the code, specifications, prompts, files and other content you provide to the Services. You grant us a non-exclusive license to use that content as necessary to provide and secure the Services for you. You are responsible for having the rights to the content you provide.
Feedback. If you share feedback or suggestions about the Services with us, you grant us a perpetual, irrevocable, worldwide, non-exclusive, fully-paid, royalty-free license to use that feedback freely, in any manner and for any purpose, without attribution. Please do not submit any feedback that you consider proprietary or confidential.
Privacy
Your use of the Services is also governed by our Privacy Policy, which is incorporated into these Terms by reference. By using the Services, you acknowledge that you have read and understand our Privacy Policy and that Fission AI will process your personal data in accordance with it. If there is a conflict between these Terms and the Privacy Policy with respect to personal data, the Privacy Policy will control.
Indemnification
You agree to defend, indemnify and hold harmless Fission AI and its officers, employees and agents from any claims and reasonable costs or attorneys’ fees arising out of (i) your use of the Services, (ii) your violation of these Terms, or (iii) your violation of any applicable law or regulation. We may assume control of the defense of any such claim at your expense, and you agree to cooperate with our defense. You agree not to settle any such claim without our prior written consent. We will make reasonable efforts to notify you promptly of any claim we become aware of.
Third-party services
Third-party services. The Services may include links to or integrations with third-party websites or services (“Third-Party Services”). We do not control, endorse or take responsibility for any Third-Party Services. You use all Third-Party Services at your own risk, and the applicable third party’s own terms and privacy practices will apply to such use.
Release. To the fullest extent permitted by law, you release Fission AI and its officers, employees, agents, successors and assigns from all claims, demands and damages of any kind arising out of or related to Third-Party Services. If you are a California resident, you waive California Civil Code Section 1542, which provides: “A general release does not extend to claims which the creditor or releasing party does not know or suspect to exist in his or her favor at the time of executing the release, which if known by him or her must have materially affected his or her settlement with the debtor or released party.”
Disclaimers
The Services are provided “as is” and “as available.” To the fullest extent permitted by law, Fission AI and its suppliers disclaim all warranties, express or implied, including warranties of merchantability, fitness for a particular purpose, title and non-infringement. We do not warrant that the Services will be uninterrupted, error-free, secure or free of viruses or harmful code, or that any output of the Services will be accurate or complete. Where applicable law requires warranties, they are limited to 90 days from your first use.
Limitation of liability
To the maximum extent permitted by law: (a) Fission AI and its suppliers will not be liable for any lost profits, lost data, costs of substitute products, or any indirect, consequential, incidental, special, exemplary or punitive damages arising from or related to these Terms or your use of (or inability to use) the Services; and (b) our total liability to you for any claim arising under these Terms is capped at the greater of (i) US$100 and (ii) the amount paid to Fission AI by you under these Terms in the twelve months prior to the incident giving rise to the claim. The existence of multiple claims does not increase this cap.
Term and termination
These Terms remain in effect while you use the Services. We may suspend or terminate your access (including suspending access to or deleting your account) at any time and for any reason, including if we believe you have violated these Terms. We are not liable to you for any such termination. Upon termination, the provisions of these Terms that by their nature should survive will survive, including ownership, feedback, indemnification, disclaimers, limitation of liability and general terms.
General
Changes to Terms. We may update these Terms from time to time. If we make material changes, we may notify you by email (at the address on file) or by a prominent notice on the Services. Your continued use of the Services after notice of changes means you accept the updated Terms.
Governing law. These Terms and any dispute arising out of or related to these Terms or the Services will be governed by the laws of the State of Delaware, without regard to its conflict-of-law principles. You and Fission AI consent to the exclusive jurisdiction and venue of the state and federal courts located in the State of Delaware, except that either party may bring an action in any court of competent jurisdiction for injunctive or other equitable relief to protect its intellectual property rights.
Export. You agree not to export, re-export or transfer any technical data or products acquired from the Services in violation of U.S. export control laws or applicable regulations in other countries.
Electronic communications. By using the Services, you consent to receiving communications from us electronically (by email or notices posted on the Services). These electronic communications satisfy any legal requirement for written notice.
Entire agreement. These Terms, together with the Privacy Policy and any other policies or guidelines referenced in them, are the entire agreement between you and Fission AI regarding your use of the Services. A separate written agreement signed by Fission AI controls where it conflicts with these Terms. If any provision of these Terms is found to be invalid or unenforceable, it will be modified to the minimum extent necessary to be valid, and the remaining provisions will continue in effect. Our failure to enforce any provision is not a waiver of that provision. The word “including” means “including without limitation.” You may not assign these Terms without our prior written consent; we may assign them freely. These Terms bind any permitted assignees.
Copyright and trademarks. Copyright © 2026 Fission AI, Inc. All rights reserved. All trademarks, logos and service marks displayed on the Services are owned by Fission AI or third parties. You may not use any of them without prior written consent from the owner.
