Start with a useful question.
What would you like to find again: a decision, a project detail or the source of a claim? A clear purpose matters more than a long list of tools.
Your files. Your context.
A Brain is a searchable memory built from sources you choose: notes, decisions and project records. It helps you find useful context again when a conversation ends or you change AI tools.
The source and the index are different.
Your original files hold the information. A search index is a derived guide that helps locate relevant passages by meaning or exact words. It is not a backup. Changes to a source may not appear until the index is refreshed.
Find the evidence. Then answer.
A connected AI can use retrieved passages to draft an answer and point back to the source. Check the source, its date and its context. Missing or conflicting evidence should remain visible; retrieval does not guarantee a correct answer.
You decide what is shared.
Reading this page does not give an AI access to your files. Access depends on the tool, its connections and your permission. A local source can still be sent to an online provider if you share it there. Review what leaves your device and who may receive it.
Options first. Your approval next.
An agent should explain suitable options and their limits, then ask before installing software, uploading documents or changing security settings. Its available tools vary. A Brain does not automatically connect every AI or remember every conversation.

Optional: copy this intent prompt to start a discussion. It gives no access and starts no action.
Help me decide whether a searchable memory would help my work. Ask what I want to find again and which sources I may use. Explain a few options, their limits and what would be shared. Do not install software, upload documents or change security settings without asking me first.
