Forget file names, folder paths, and "what was his name again." Put everything into your brain — then just ask. It's private. It's yours. And only if you choose, others can connect to it too.
Forward an email to your private brain address. Drop a PDF into a watched folder. Connect a bank. That's the whole setup.
Your brain understands what's inside. It extracts dates, amounts, names and relationships, and quietly encrypts the sensitive bits before they leave your machine.
"How much did we spend on software?" "Which lawyer did Maria recommend?" Real answers, cited from your own stuff. Not web slop.
Every email, receipt and confirmation becomes searchable. Your brain gets a private address like you.x7k2@getrapu.ai — forward to it and you're in.
Contracts, tax, medical, insurance. The desktop app watches a folder you pick — anything inside gets ingested, indexed, and encrypted.
Import statements. Transactions matched and categorised. Ask it how much you spent on software, and it'll tell you.
Your brain stitches people together across emails, documents, and notes — so the answer takes one sentence, not twenty minutes.
Legislation, court decisions, and government proposals — always up to date, always searchable. UK, Finnish and Estonian law today.
A contract mentions a company that appears in three emails and an invoice you paid last spring. Your brain shows the whole thread, not a search result list.
Rapu is MCP-native. Any modern LLM client — Claude Code, Claude Desktop, Cursor, your custom agent — plugs in once and gets your brain's full memory, entity graph, calibration data, and reasoning surfaces. The brain stays with us. The conversation happens wherever you already work.
The personal-brain MCP service plugs into your existing CLI workflow. Your code agent now knows your real corpus, not just public training data.
Drop a snippet into your claude_desktop_config.json, restart, and Rapu's tools appear in the tool panel — ready for any conversation.
Cursor, Zed, Anthropic SDK, OpenAI agents through a bridge, your own loop with the official MCP libraries — Rapu is a standard MCP server. No proprietary protocol, no vendor lock-in.
Not just retrieval. Your LLM, augmented with semantic search across your documents, a graph of your entities and their relationships, typed claims with confidence and decay, a calibration loop that tracks which of your commitments came true, and an argumentation surface that computes which of your claims are defensible.
This is Anna's brain — a fake person, but a real demo. Her lease, her lawyers, her Q1 travel. Ask a question and see what comes back.
Rapu is built the way we'd want something that holds our whole life to be built. Not a compromise we hope to fix later.
AES-256-GCM, the bank standard. Keys stay with you.
Personal IDs and bank numbers are detected on your computer and encrypted before upload.
Every search, every access, every share is recorded. The log can't be modified without detection.
No passwords, no email signups. Your account is tied to a verified digital identity from day one.
Your documents, your relationships, your finances — they're not training data and they're not ours to lose. Rapu stays on your side or it doesn't exist.
