Terms of Service

Last updated 6 July 2026.

1. The service

BraneWave lets authors create an AI “twin” trained on their own books, talks, and writing, and lets readers hold conversations with those twins. Twins are AI systems: they aim to answer in the author's voice, grounded in the author's work, but their answers may be incomplete or imperfect and are not professional, legal, medical, or financial advice.

2. Accounts

You must provide accurate account information and keep your credentials secure. Authors are required to use two-factor authentication. You are responsible for activity under your account.

3. Authors and their content

Authors retain all rights to the content they upload. By uploading, an author grants BraneWave a licence to process that content solely to operate their twin. Authors must hold the rights to everything they upload. Authors may review any conversation held with their twin and may correct or supplement its answers.

4. Acceptable use

Do not use BraneWave to break the law, to attempt to extract other users' data, to probe or disrupt the service, or to misrepresent a twin's answers as the author's personally written words.

5. Subscriptions and billing

Paid plans are billed through Stripe. You can cancel at any time; access continues to the end of the paid period. Prices are shown on the pricing page.

6. Privacy

Our privacy policy — including the no-employer-sharing, no-training, and no-selling guarantees — forms part of these terms.

7. Termination

You may delete your account at any time. We may suspend accounts that breach these terms. On deletion, your data is erased within 30 days as described in the privacy policy.

8. Liability

The service is provided “as is”. To the maximum extent permitted by law, BraneWave's liability is limited to the amount you paid us in the twelve months before the claim. Nothing in these terms limits liability that cannot be limited by law.

9. Changes and governing law

We will notify account holders of material changes to these terms. These terms are governed by the law of England and Wales.
