A normal app
My Brain
The whole idea, in one line
Next chapter shows it happening to a single thought. Keep going. →
Chapter 2 · how it works
No diagrams to decode. Just watch one little thought travel all the way through the system. Tap any stage, or let it play.
you say it once — then forget it. The brain doesn’t.
▶︎ Playing… watch the thought move down. Tap any stage to explore it.
That’s the entire architecture. One thought in, four stages, and it lives in your brain forever — ready to come back.
and it’s not just to-dos
Same machinery, anything you give it — a task, a password, a person, a question, a whole meeting.
Chapter 3 · capture
No forms, no fields. Talk for a minute and a whole day assembles itself — work and family, sorted, prioritized, timed.
🎙️ 7:02 AM — you, speaking:
✨ your day, one second later:
📌 Send the revised quote to the architect [💼 work · high · 30m]
○ Book the dentist for Amma [🏠 personal]
○ Pick up the school project supplies [🏠 personal]
○ Review the vendor contract [💼 work · 45m]
Hold-to-talk on every screen, with live transcription and an AI tidy-up. Morning dump, night story, a quick note — all by speaking.
Paste text, drop a file, import from Google Drive. It’s summarized, filed into memory, and gets its own private chat.
Forward a link to Telegram, send a voice note, reply to a reminder — it all lands in the same brain.
Chapter 4 · how it remembers
Everything you save is written into two independent memories at once — one a memory engine we built ourselves, running on your own server — and quietly kept in perfect sync. If one ever falls behind, it heals itself.
a memory being saved…
idleWe didn’t rent this — we built our own meaning-aware memory engine, running on hardware you control. Everything you save is searchable by what it means, not just keywords — and it never leaves your box.
A second, fully independent memory — redundancy by design. A queue keeps both in lock-step so a memory can never be lost.
And you hold the controls: a Settings → Index panel shows every section, what’s indexed, when it last synced, live RAG-vs-SuperMemory counts — with a one-tap Reconcile now. Turn any section off and it’s purged from search.
Chapter 5 · memory & search
It searches by meaning, not keywords — and every answer cites the real things it came from.
A live, illustrative simulation — tap a question.
Chapter 6 · talk to your brain
No menus, no folders to dig through. Ask in plain words — it works out where to look, reads your memory, and answers with the receipts.
in the real app, tap any source chip to open the exact item it came from.
Ask inside one area — bookmarks, your life, a single document — or let it search absolutely everything at once.
Every answer cites its sources — tap one to jump straight to the real task, story, email or doc it came from.
Suggested follow-ups, saved answers, and a private chat on any single document — plus ask by voice, or ⌘K from anywhere.
Chapter 7 · the daily loop
One gentle loop, every day. Tap a step.
👆 Tap a step to see what happens there.
One story · two lives
The client call you dreaded turned into the win of the week — they signed. You closed three threads you’d been circling for days, and it shows: you ended work lighter than you started it.
🧭 Mentor: “Work is winning at 78 while home sits at 52 for the third week. The proposal can wait one evening — Thursday’s dinner cannot.”
Daily stories roll up into weekly reviews, monthly chapters, and a Story of the Year — your life, written as a book.
Focus areas, an on-track score with a trend line, a nightly note, and a 4 PM nudge to land the day well.
Who matters keeps surfacing — names, context, and how your weeks revolve around them.
Chapter 8 · the lab
Every night, My Brain studies your day the way a scientist studies data — and slowly, carefully, learns who you actually are. Your own personal scientist. 🔬
What you did, what you kept putting off, what you skipped — plus your story, your mood, your emails and your meetings.
The richest signal about a person isn't what they do — it's what they defer and abandon. The Lab weighs your inaction the heaviest.
It builds a living map of what you do ↔ how you feel ↔ who's involved ↔ when — the real wiring of your days.
Tap ✓ if it's right, ✗ if it's not. Your taps are the experiment. (go on, try it 👇)
Money & admin tasks drain you — and you keep deferring them.
Saturdays are your deep-work sanctuary — your best output lands then.
You avoid conversations where you must hold someone accountable.
Each insight carries a confidence % and its evidence. It grows stronger every time it recurs — and fades on its own rhythm when it stops (a weekly pattern won't fade on a Tuesday). Old phases quietly retire; the real you stays.
See it all in The Lab: a living graph of you ↔ feelings ↔ people ↔ tasks, your mood trend, what energizes vs drains you, and heatmaps of your week and your avoidance.
It's honest — no flattery, just what the evidence shows. It's private — your patterns are yours, and you can pin or delete any of them. And nothing is ever "known" about you that you didn't confirm.
It doesn't just hold your life — it understands you, and keeps understanding you better.
Chapter 9 · the vault
A full password manager built in — and built so that even the app can’t read it.
Everything is encrypted in your browser with your master passphrase before it’s ever stored. The server only ever holds an unreadable blob — no one can decrypt it but you.
Face ID / fingerprint unlock on your device, a forced Recovery Key at setup, and auto-lock the moment you step away.
Only the labels (the site name) are searchable — the secret itself is never added to memory, never sent to any AI.
logins, cards, bank, crypto, identity, API keys, docs, licenses, Wi-Fi, memberships, notes
password generator + weak / reused detection + a security view
tap to copy a password — the clipboard auto-clears in 30 seconds
re-enter your passphrase before a seed phrase or private key is ever shown
import from 1Password, Bitwarden or CSV — encrypted in your browser
attach a passport scan or doc — sealed the same way
type tabs, table or card views, collections, favorites, audit log
export the whole vault — still only readable with your key
Chapter 10 · works with your world
It meets you where your day already happens — and treats every connection like a vault.
A nightly Daily Brief of what actually mattered, an in-app thread viewer, and important emails recalled by your brain. Connected through Google’s own secure sign-in — you stay in control, and can switch it off and purge anytime.
A daily pass quietly finds non-obvious links across everything you’ve saved — “this idea connects to that meeting three weeks ago” — and surfaces them on your home screen.
Record & transcribe, then an AI summary with takeaways and decisions — searchable forever.
“I’ll send it by Friday” is caught automatically and tracked until it’s done or dropped.
Your day’s events at a glance and one-tap import of Docs, Sheets and Slides into memory.
Tap a connection to see its role.
👆 Tap a connection.
Chapter 11 · make & know
A second brain isn’t only memory — it’s where you make things and keep what you learn. Capture a thought, grow a rough idea into a real plan, save what matters, and let it record the rooms you’re in.
Paste, type, dictate or import — a link, a doc, a stray thought. One box; the brain files it.
Quick notes and checklists — searchable forever, never lost in a folder.
Save links with a summary; ask your brain for “that article about pricing” months later.
Hold to talk — live, Wispr-style, with an AI clean-up pass. Speak anywhere you’d type.
Record a meeting → transcript → a clean summary with takeaways and decisions, kept in your brain.
Reusable skills you’ve built — your brain knows them and can run them on command.
the standout
Drop in a rough idea and your brain grows it into a real plan — then hands you a ready-to-run agentic prompt for a coding agent. From a sentence on the bus to a workflow an AI can execute. Your ideas don’t just sit there; they get built.
Chapter 12 · the engine room
Most “AI apps” quietly run up an API bill and hide the controls. My Brain hands them to you — pick the engine for every feature, read and edit the prompts, watch the usage, and run the heavy work on subscriptions you already pay for.
Background AI work runs through your Codex and Gemini CLI agents — on subscriptions you already have — instead of metered API calls. If an engine is ever down, it falls back automatically to Claude Sonnet so nothing stalls. Real power, without the runaway bill.
Choose which engine writes your story, your email brief, your commitments — feature by feature, in Settings.
The system prompts behind every feature are yours to read and tune. Nothing is a black box.
A usage view shows what the AI is doing under the hood — no surprises.
The Index manager: turn any section of your memory on or off, see RAG-vs-cloud counts, and Reconcile in one tap.
In short: you are in control of the AI, the models, the cost and the memory — not the other way round.
Chapter 13 · the full catalog
The whole brain, end to end — nothing left out. Sixteen areas, a hundred and fifty-plus little powers.
Chapter 14 · the road ahead
The brain lives in your pocket and on your server today. Next, it reaches into the physical world.
Dedicated devices for a few focused use-cases — so capturing a thought and getting it back is as natural as speaking into the air.
in the worksA purpose-built Android app for a handful of high-value use-cases — faster capture, deeper notifications, always within reach.
next upSame brain, more doors into it.
Chapter 15 · built right
Every single feature shipped through an enforced pipeline. Nothing reaches you on trust.
Versioned privately · data pulled to a second machine at home every night · every backup integrity-tested · a watchdog guarding it all.
Login, the twin-memory engine, the design system.
Capture, bookmarks watched by AI, ideas and skills organized.
The daily loop, the Story of the Day, Telegram by voice.
The mentor, focus areas, on-track score, suggested tomorrows.
Gmail, meetings, commitments, connections, semantic Explore.
A zero-knowledge vault — and next, hardware and a native app.
Every day it runs, it knows one day more. The version you meet next year will know its owner better than any product ever has.
