Rae is in open beta and is freely available. These guidelines govern your use of Rae on the Free tier and explain, in plain English, what you may and may not do. The Rae Free Tier Licence Agreement (the Licence) requires you to follow them. If anything here conflicts with the Licence, the Licence takes precedence.
During the open beta, you may use Rae without charge, including for commercial purposes. Buying additional build credits is optional.
We may end the open beta at any time by giving notice on the Rae Platform or at raelog.ai.
1. Who may use the Free tier
You must be 18 or over to use Rae. You may use it for education, evaluation and training and, during the open beta, for commercial purposes. If you use Rae as a private individual rather than for a business, your use must be non-commercial.
During the open beta, any organisation is welcome to use the Free tier. After the open beta, individuals or organisations with more than US$25 million in revenue or more than 250 employees need a separate licence agreement with us to use Rae commercially.
2. Commercial use
During the open beta, you may use Rae commercially, either within your own business or to power your own commercial product. You may not resell, sub-license or white-label Rae itself, or Rae decisions as a standalone service, without a separate agreement with us.
3. Decisions
A decision starts with a question you put to a Rae model resulting in an answer: either one or more recommended solutions, each with a certainty rating and evidence tree, or a statement that no solution is available. Both outcomes count as a decision. During the open beta, decisions are free. We may set limits on the number or rate of decisions and will tell you if we do.
4. Build credits
Free accounts receive an allocation of build credits for AI-assisted building. Sign-up credits expire 12 months after they are issued and are not refundable. Once they are used, you may request more or buy more, depending on the option that is presented to you in Rae.
For the first week or two of the beta, you can also switch to your own Anthropic API key. This option will be withdrawn, after which additional build credits can be bought from us.
5. Fair use
Sign up for and use Rae in good faith. You may hold one Free account per person. You must not share login details, open additional accounts or use automated means to get around any limit. If you are a business, you are responsible for how your employees use Rae.
You must not use Rae for any unlawful purpose or in breach of export control laws, copy, modify or reverse engineer the platform, or attempt to probe, test or circumvent its security. If you become aware of any unauthorised access to your account, tell us immediately.
6. Competitors
You may not use Rae if you, or the organisation you work for, offer a product or service that competes with Rae. You may not use Rae to build or help build a competing product or service.
7. Your models and content
You own the content you create in Rae, including your models written in Raelog, your sources, inputs, outputs and evidence trees. We host and process it only to provide Rae to you, and we will not share it with other users without your consent. You can download your own copies: if your licence ends, we may delete this content.
8. Service limits
The Free tier is hosted in the United Kingdom. We do not guarantee availability, uptime or the quality of what is produced on Rae under a Free tier. We may carry out maintenance or change the platform without notice, and we do not provide technical support on the Free tier.
The Free tier does not support HIPAA compliance, so you must not process protected health information on it. If you need a choice of hosting region, a service level, single-sign-on, support for HIPAA or other enterprise features, please contact us about a different licence.
9. Getting help
You are welcome to ask and answer questions in the Rae Discord at:
When asking for help, please post a minimal model that shows the problem. Do not post spam or anyone else's private work.
10. Built on Rae badge
Displaying the Built on Rae badge is optional. If you choose to use it, we may, with your consent, feature your solution in the Rae showcase, and you can earn free build credits for your account.
11. Ending your use
Either of us may end the Licence for any reason by giving the other 14 days' written notice. We may end it immediately if you commit a material or persistent breach of the Licence, including these guidelines, and do not put it right within 14 days of our notice. When it ends, you must stop using Rae and we may delete your content.
12. Changes and contact
We may update these guidelines from time to time, and the current version will always be published on this page. The Licence is governed by English law.
