Plain terms for research membership.

Legacy beta

Feynman is in private beta. Invite codes are personal, so please don’t share them. We may change, pause or end the beta, and the reviews in your browser stay yours if we do.

Membership and billing

Accepted applicants may purchase one individual membership for £225 every three calendar months, paid in advance and automatically renewed until cancelled. The displayed total is the amount charged; tax treatment is shown on the invoice. Each paid period includes 9,000 Feynman Research Credits, not model tokens. There is no free trial, hidden overage or automatic top-up. Unused credits expire at renewal; no rollover applies.

Every investigation shows a maximum credit quote before you confirm. Credits are reserved, charged at the disclosed fixed tariff for a completed report, and fully released if the investigation fails. Reading saved reports and standard exports costs no credits. Intake is limited to 20 new records per day, with supported files up to 4 MB and 60,000 characters.

Cancel the next renewal from Membership in your account. Access continues until your paid period ends. Existing records remain available for reading and export until you delete your account. Account deletion immediately cancels the subscription and removes active private research data.

Nothing in these terms limits statutory consumer rights. Refund requests, withdrawal rights and disputes will be handled under applicable law. Paid checkout is not open while launch validation and consumer billing review are outstanding.

Research accountability

You approve reconstructed claims and remain responsible for experiments, authorship, institutional permission and publication. A Feynman report is not peer review or a certification of truth. No work is automatically published. Abstract-only evidence, unexecuted computations and informal proof critique are labelled accordingly.

Not professional advice

Feynman reviews reasoning and published evidence. It is not medical, legal, financial, investment, engineering or safety advice, and it does not replace a qualified professional. Where being wrong could hurt someone, check with one before you act.

What a verdict does not promise

• A verdict and its stated chance are the model’s estimate from the records it found. They have not yet been checked against how ideas turn out.
• A review can be wrong, miss a hole, or misread a source. Its sources are summarised from abstracts, so read a paper before relying on it.
• A hole marked reasoning only means the search found no record, not that none exists.
• The model may decline material it won’t review. That is not a verdict on the idea.

Your ideas

You keep ownership of the ideas you bring and everything you write. You let us process them only to produce your review, as the privacy page describes. Bring only what you have the right to share, and leave out other people’s confidential information.

Fair use

Don’t use Feynman to break the law, to harass or defame anyone, to seek help causing harm, or to overload or probe the service.

The names

Feynman Works is an independent laboratory, not affiliated with Richard Feynman’s estate or with Caltech. The lenses are ways of reasoning drawn from published work. They do not speak for, quote or represent the people they are drawn from.

As it is

The beta is provided as it is, without warranties, to the extent the law allows. To the same extent, we are not liable for decisions made on a review.

Changes and contact

If these terms change, we will update this page and its date.
