An agent. A browser. A canvas. A docubase. An experience
freaking good.

Everything you study.
In one place that thinks with you.

Read anything, excerpt it into cards, connect the cards into maps, and ask an agent that has actually read your notes.

An agent.

It has read your notes.
So it actually helps.

Ask about a theorem and the agent opens the page it lives on, searches your cards, and answers with the math rendered properly. When it changes your map, every step can be undone.

Reads with you

Pages, slides, notebooks and your own cards are all in reach. It cites where it looked.

Works on your library

Creates cards, files sources into folders, builds maps. Asks before anything destructive.

Vibing

Point it at a project folder and code together: read, edit, run, test. On a phone, too.

A browser.

The web, as a source.

A real browser lives right next to your notes. Select a sentence on any page and it becomes a card that links back to where you found it. Sign-ins stay put, your Chrome extensions come along.

Extensions welcome

Ad blocking, translation, the extensions you already rely on.

Save the video

Finds the video on a page and downloads it into your collection, subtitles included.

A canvas.

Ideas, connected.

Every excerpt is a card. Arrange cards into maps, nest them, color them, write LaTeX in them. One card can live in many maps, and stays one card.

A docubase.

Open it. Whatever it is.

Lecture PDFs, slide decks, spreadsheets, Jupyter notebooks, LaTeX, e-books, podcasts and lecture videos. Each one opens natively, and each one can be excerpted, linked and searched.
