a commonplace book for one brain

One brain. Notes you write, notes that arrive from everywhere else, and a memory other minds can recall from.

Open Engram → engram · the trace a memory leaves in a brain
Everything you write, everywhere, in one memory.
01

A gorgeous place to write

Markdown-canonical, keyboard-first, instant. The app opens ready to write, cursor already blinking. No folders, no filing. Type [[ to link a thought to another.

02

The roll-up

Notes made in other apps flow in through one signed door. Your journal, your vault, your meeting transcripts, all accumulating in one place, each with its origin stamped on it. You never edit a source's words; you respond to them.

03

A memory for agents

The same recall that powers the app powers an API any agent can read from and write to. An agent is just another source. Its writes land in your stream, stamped, like everything else.

Your brain organizes itself.

A curator reads each memory as it arrives and quietly maintains a layer of synthesis pages behind your raw notes. The bookkeeping you always abandon, done at near-zero cost. It never touches your words; it writes its own, stamped, so what you recall stays yours and what it distills is always traceable back to the source.

See the shape of your brain.

Every wikilink is an edge. The pages the curator pulls the most together grow into hubs; raw memories stay quiet dots. It settles, and stops.

curator page memory unresolved
Four surfaces. Nothing else.
the Stream

A reverse-chronological river of everything, from every source, under day headers. The app opens here, ready to write.

the Note

One memory at a comfortable measure. Backlinks below, related memories in the margin, provenance in the header.

the Palette ⌘K

The only search. Fuzzy titles, full text, semantic recall. Filters are typed, not clicked: #tag, from:compass, before:2024.

Sources

The provenance ledger. What is connected, what agents can read and write your brain, and the health of the whole graph.

Why Engram.
⊙ en·gram · noun · neuroscience

The physical trace a memory leaves in the brain. The lasting mark by which a single memory is stored, and later recalled. Named in 1904 by the biologist Richard Semon, and hunted ever since as the material substrate of remembering.

The name is the whole idea. Engram keeps the trace, not a summary of it. Every memory carries where it came from; nothing is flattened into an anonymous digest. The curator distills, but only into its own stamped pages, always traceable back to your words.

It is why the product recalls rather than chats. An engram is not performed. It is left behind, and found again.

Write something worth remembering.
