The privacy layer
for personal AI.

Pseudonymize first. Reason in the cloud. Resolve at home.

Braince sits between your life and any cloud LLM. Real names, deals and numbers never leave your boundary — the model only ever sees pseudonyms. You see your full context.

View plansHow it works

The problem

Personal AI has a privacy problem nobody fixed.

01

Cloud AI is most useful when it sees everything.

State-of-the-art LLMs need your full context — emails, contracts, voice memos, medical notes — to be genuinely helpful. That same context is the most sensitive data you have.

02

Regulation just made that a liability.

EU AI Act enforcement, GDPR-scale fines, U.S. state privacy laws, and sector rules (think financial and healthcare oversight). Sending PII to a consumer LLM is now a compliance exposure for every regulated profession — and a reputation risk for every founder.

03

The customers who would pay refuse to upload.

Founders raising. VC partners. Family-office principals. Lawyers, doctors, therapists. The people who would pay $1,500/yr for a real AI chief of staff — won't put their lives in a cloud they don't control.

How it works

One round-trip.
Three boundaries.

Watch a single voice memo become a useful answer — without your real names, deals or numbers ever leaving your control.

  1. Step 01
    Voice memo — your boundary
    Captured on your device. Not yet seen by any cloud.
    Schedule a follow-up with Henry Ford re: the River Rouge expansion next Tuesday — he wanted $4.2M valuation.
  2. Step 02
    Pseudonymized — leaves your boundary
    Local model rewrites every entity. The legend (who is who) stays on your machine.
    Schedule a follow-up with PERSON_A7 re: PROJECT_K3 next Tuesday — wanted VALUE_X1 valuation.
  3. Step 03
    Cloud LLM — sees pseudonyms only
    Claude, GPT, Gemini — your model of choice. Reasoning quality unchanged.
    Booked Tue 15:00 with PERSON_A7. Note: review March terms for PROJECT_K3 before call. Flag VALUE_X1 vs comparable PROJECT_K2 multiple.
  4. Step 04
    Resolved — back at your boundary
    Pseudonyms are replaced with your real entities. Only you ever see this.
    Booked Tue 15:00 with Henry Ford. Note: review March terms for the River Rouge expansion before call. Flag $4.2M vs comparable General Motors multiple.

For whom

Built for the people cloud AI can't serve.

Founders raising. VC partners reviewing decks. Family-office principals managing wealth. Lawyers, doctors, therapists, consultants. Anyone whose context is too sensitive to upload — and too valuable to ignore.

VC partners
Pipeline notes, partner memos, fund-level positions.
Founders raising
Cap-table conversations, term sheets, investor signals.
Family offices
Holdings, advisor conversations, succession planning.
Regulated professions
Lawyer-client privilege, medical records, therapy notes.

Questions

The honest short answers.

Where does my data live?
On your devices and on a private store you control. Pseudonymization happens locally before anything leaves your boundary. The legend — who PERSON_A7 actually is — never leaves with the request.
Why can't OpenAI or Microsoft just build this?
Their margins depend on training, retention and personalization. "Don’t trust the cloud" is architecturally incompatible with selling cloud. We’re built to be the layer they can’t ship.
Will it work with the assistants I already use?
Yes. Braince is the layer between your data and any cloud model. Keep using Claude, GPT or Gemini — Braince just makes sure they never see real names, deals, or numbers.
When can I get in?
Braince is in private beta. Choose a plan and leave your email — we’ll send an invite as soon as your spot opens.
