Terms of service

Last updated 4 October 2026

Who we are

Your Brain Today is operated by Your Business Today Ltd, a company registered in England and Wales under number 17329446, with its registered office at 8 Eastleigh Close, Sutton, England, SM2 6QY (“we”, “us”). You can reach us at consulting@yourbrain.today.

These terms govern your use of yourbrain.today and every part of the service: accounts and credits, knowledge bases and the brains inside them, chatbots, and the API and MCP server. By creating an account, or by accepting a chatbot invitation and signing in, you agree to them. If you are using the service on behalf of a business, you confirm you have authority to bind that business.

Early access

The service is in early access. Features may change, grow, shrink, or be withdrawn as we build. Where a change materially affects something you have paid credits for, we will give you reasonable notice where we can.

Your account

You can sign in with Google, or with an email address and password. Your account is yours alone: keep your credentials secure, and tell us promptly if you believe someone else has used them. You are responsible for activity that happens under your account, you must be at least 18, and the information you give us must be accurate and kept up to date.

Credits and payment

The service is paid for with credits, bought in packs through our payment provider, Stripe. The price of each pack is shown before you buy, and the credit cost of each action — an interview reply, a document read, a question to a brain or a chatbot — is shown in the service before you take it. The cost of an answer depends on the model you choose for it.

Credits are a prepayment for services, not money. They carry no cash value, earn no interest, and cannot be exchanged outside the service, although you can send credits to another account holder using the sending feature. Promotional credits we grant are free of charge and can be withdrawn if unused.

If you change your mind about a pack within 14 days of buying it and have not spent any of its credits, contact us and we will refund it. Once credits from a pack have been spent, the work has been done and the pack is no longer refundable, except where the law says otherwise. Nothing in these terms limits your statutory rights as a consumer.

Knowledge bases and the four brains

A knowledge base holds what a business knows in four kinds of brain: an expertise brain for the rules and language of the trade, an experience brain for the record of jobs, events and decisions, a process brain for how the work moves, and a human brain for the people around the business and how they relate to one another. You build them by answering the interviewer or by uploading documents, and the service reads what you give it and files it in the right brain.

Everything you put into a knowledge base — the documents you upload, the answers you give, and the brains built from them — remains yours. You grant us the licence we need to host, process, and display that content in order to run the service for you, and for nothing else. Your content is never sold, never pooled with other customers’ content, and never used to train models for anyone else. You can export an expertise brain as Markdown at any time, free of charge.

You are responsible for having the right to upload what you upload, including any personal data it contains about other people, and for telling those people where the law requires it.

Chatbots

A chatbot lets people you choose ask a knowledge base without opening it. When you set one up you are its manager: you fund it from your own credits, invite members by their email address, and decide how much each member may spend. Members sign in with the invited address and are bound by these terms when they do.

To generate an answer, the member’s question and the relevant parts of the knowledge base are sent to Anthropic. As manager you must tell your members this, and tell them that their questions are kept on record, before you invite them, and you must not use a chatbot to monitor people in ways the law does not allow.

You can remove a member, stop funding a chatbot, or delete it at any time. Deleting a chatbot deletes its conversations and its question log.

The question log

Every question put to a chatbot, and the answer it gave, is kept in a log against that chatbot: who asked, when, the exact question, the exact answer, and the pages it drew on. Questions the knowledge base could not answer are logged too, so the manager can see the gap and fill it. The log exists so that the manager can show what was and was not asked if a dispute arises about what the chatbot said.

The log is a record, not a working document: neither a member nor the manager can edit it or remove entries from it inside the service. The manager can read it and download it. It is kept for as long as the chatbot exists and goes when the chatbot is deleted.

Questions asked of a knowledge base through the API or MCP server are recorded in the same way against the knowledge base, for its owner to read.

API tokens and MCP

You can connect Claude and other tools to your knowledge base through our API and MCP server, either with a token you mint in the service or by authorising an application through OAuth. A token is a secret: anyone who holds it can do what you can do with it. Keep tokens safe, mint one per tool, and revoke any token or authorisation you no longer need.

You are responsible for what a connected tool does with your access, and for reviewing what an application asks for before you authorise it. We may revoke a token or authorisation that is being misused.

AI-generated answers

The interviewer’s replies, the brains, chatbot answers, and everything else the service generates is produced by AI. It can be incomplete, out of date, or wrong, and it is not legal, financial, tax, or other professional advice. Check anything important before you act on it. Decisions you make based on the service’s output are yours.

Sharing

You control who sees your work. Sharing a knowledge base gives the person you name read-only access to it, so share only what you are happy for them to see. You can withdraw a share at any time.

Acceptable use

When using the service you must not:

• upload content that is unlawful, or that infringes someone else’s rights;
• attempt to disrupt, overload, probe, or gain unauthorised access to the service;
• use the interviewer, a brain, or a chatbot to generate unlawful or harmful material;
• circumvent credit charges or manipulate credit balances;
• share a token or authorisation with someone who should not have your access;
• resell access to the service, or to a chatbot, without our written agreement.

Ending your account

You can stop using the service at any time, and you can ask us to delete your account, which removes your knowledge bases, your chatbots and their conversations, and any unspent credits — export anything you want to keep first. Records we must keep by law, such as purchase records, are kept for as long as the law requires.

We can restrict, suspend, or delete an account that breaks these terms. Where it is reasonable to do so, we will warn you first.

Our liability

During early access the service is provided as it stands, without warranties beyond those the law implies. Nothing in these terms excludes liability that cannot be excluded under English law, including for death or personal injury caused by negligence, or for fraud.

Beyond that, our total liability to you under these terms is limited to the amount you paid us for the service in the 12 months before the event giving rise to the claim, and we are not liable for loss of profit, loss of business, or losses caused by relying on AI-generated output without checking it.

Changes to these terms

We may update these terms as the service grows. If a change is material we will flag it on the site or by email before it takes effect. Continuing to use the service after a change takes effect means you accept it; if you do not, stop using the service and ask us to delete your account.

Governing law

These terms are governed by the law of England and Wales, and the courts of England and Wales have jurisdiction over any dispute — although if you are a consumer you keep any protections and venue rights your local law gives you.
