Iroh: your second brain, just by talking

Iroh is the easiest way to build a second brain.

Everyone wants a second brain. Nobody wants the setup. Talk for two minutes and Iroh builds you one, a living map of your whole life you can ask anything.

Watch it build

You talk. Iroh draws your brain.

Say what is on your mind, the way you actually would. Iroh listens, files each piece where it belongs, and connects it to the rest of your life, live, into one map you can see.

Listening
Coffee with Maya Thursday, she's hiring for her startup.
Idea: a weekend trip to Lisbon in October.
Bench felt strong today, 185 for five.
Mom's birthday is the 14th, get her the ceramics.
Still need to follow up with the landlord about the lease.
Your brain

Two minutes of talking. A living map of your whole life, already connected. No folders, no tagging, no setup.

None of the setup

Hours of setup, done in minutes.

Every other tool hands you an empty canvas and a second job: pick the templates, build the structure, file each note, keep the whole thing current. That is the work that makes people quit before they start.

Iroh does that part for you. You talk; it does the building, the filing, and the connecting, and keeps itself current from the things you say in passing. The brain you always meant to have, without the setup you never finish.

What it feels like

What living with Iroh feels like.

From a passing thought to a brain that knows you. A few moments from an ordinary week with your life finally in one place.

A home that knows you

The AI that actually knows your life.

Open Iroh and it already knows what you are working on, what you decided last week, and what is on your mind lately. Not a blank chat box. A home that opens onto your real context.

Iroh recapping your week from connected health data: a day-by-day table of steps, distance, and active calories with a plain-language summary.
Voice capture

Just talk. Iroh files it for you.

Speak a thought and Iroh transcribes it, understands what it means, and routes it to the right pages, creating new ones when it needs to. No folders to pick. No tagging. No filing.

Iroh acting on a spoken request, reading your current health data and the right page before it answers.
A graph that connects itself

Watch your brain connect itself.

Every note you add finds its place and links to what you already know. Your brain shows up as a living constellation that grows a little brighter every time you talk to it.

Living docs from your life

Turns your life into living docs.

Trackers, projects, people, decisions. Iroh keeps real documents up to date from the things you say in passing, so the page is always current without you ever opening it.

Connectors

Connected to your calendar, Drive, and more.

Link your calendar and Google Drive and Iroh answers from your real world, pulling the right file or the right meeting into the conversation. More connectors are on the way.

One connected brain

Your life isn't fragmented. Your tools are.

The thought is in one app, the plan in another, the detail buried in a chat you will never find again. Every other AI starts from zero each time you open it. Iroh holds the whole picture in one place, so you can finally ask your life a question and get a real answer.

Eight places, none of them talking to each other.

With Iroh

One brain that already knows how all of it fits together.

Privacy

Your most personal brain, kept yours.

Iroh holds the details of your real life, so privacy is built in, not bolted on. The whole deal, in three lines.

Your brain lives on your device.

Your brain is 100% local to your phone, or your iCloud if you choose. If Iroh vanished tomorrow, it would still be yours and still readable.

No AI trains on your data.

A hard rule: the AI reads your brain to help you, but never trains on it. That is a contract we hold our providers to, not a setting you have to toggle.

Export or delete, anytime.

Your brain is plain markdown. Take it with you whenever you like, or wipe it completely. No lock-in, on purpose.
