A place for what you know.

Much of what you know is not text. It is a PDF, a recording, a sheet someone shared with you. Those can stay in Google Drive. Your brain is split into spaces, one for each part of your life, and a space can link to the Drive folder that holds its documents.

Your notes can be distilled from those documents, and they reference them. An agent reads the homework from your teacher or the quote from the roofer, proposes what belongs in your notes, and links each line back to the file it came from.

And they are still Drive documents. Share one with anyone and work on it together, while your own notes on it stay in your folder. An agent changes a shared document only when you approve it.

A brain is a folder of spaces: a French class, the house, a project at work. Notes and logs are always there; a space can also have documents and an inbox, each with its own job.

A space starts with a README, a few lines in your words about what it is for. An agent reads it before it touches anything.

So you and your agents know where something goes before opening the folder. A space can hold smaller ones with the same shape. Any other folder you make is yours, and agents leave it alone.

Itakua is your notes, and it is your agents' memory. Same folder, same files. What you write, they know. What they do, you can see.

For you, that means notes that stay in order. Everything has a place, so you can find it later and trust it when you do. For your agents, it means starting from what you already know instead of a blank page.

Record a class, save a file, or write down a thought. Put it in the inbox and it waits. Nothing processes it on its own.

When you ask, an agent reads the item, writes the log entry and proposes a change to your notes. Automation proposes. You decide.

Itakua does not move your files. Keep the brain in iCloud Drive, in Dropbox, in Git, or on whatever already carries your folders between devices.

Text and documents travel separately. Notes and logs go wherever the folder goes. When a space uses Drive for recordings, PDFs or slides, those files stay there and your notes link to them.

Each space's README travels with the folder, so an agent on another machine starts from the same instructions.

The Reader opens your brain on a phone or in any browser. Search every note, pick up where you left off, fix a line while you wait for the bus.

Each note says where it lives and when it last synced. A link to another note and a link to a document look different, because they are different things.

Prefer Obsidian? Every brain is already a valid vault. Open the same folder there and keep your plugins.

One socket serves the same brain to each agent you use, at your desk or on your phone. You choose which spaces it serves.

An agent sees only the notes and READMEs in the spaces you serve. It does not see logs, the inbox, documents or other spaces; hidden spaces do not appear in results.

It is read-only. An agent can offer you text. The brain changes only through you.
