The thought you had in the shower on Tuesday.

Steno is a second brain — an annotated record of everything worth remembering, kept the way you actually take notes: in fragments, in passing, in the margin.

Capture, before the thought evaporates

You write the way you think — half‑sentences, quotations, a name you promised to look up. Steno accepts the note in whatever shape it arrives,¹ timestamps it, and gets out of the way. There is no “new note” ceremony, because ceremony is where fragments go to die.

Filing is the wrong verb

The old note‑taking model asks you to file link — to decide where a thought lives before you’re allowed to have it. Steno revises this: it reads your note, proposes the connections it already sees,² and lets the web of your thinking grow the way marginalia grows in a well‑read book — outward, at the edges, where the reader was actually paying attention.

Recall, not search

Three weeks later, you won’t remember the words you used. You’ll remember the shape of the thing: that book, about why dashboards lie. Steno answers the question in your own vocabulary and returns the note together with whatever quoted it, argued with it, or was written because of it.³ Memory is context; a second brain that returns facts without context is just a search engine with better manners.
