A treehouse with a slide and a rope ladder!
What a great idea!
You and your chat helper dream up a great idea. That's a nut.
Watch Cogi work
Chapter 1 of 7
Every good idea you have while chatting with an AI helper is a nut. Most helpers drop their nuts and forget them. Cogi the squirrel picks up every single one, keeps it safe, and finds it again in a blink.
For grown-upscogito-mem is a memory that runs on your own computer. Claude, Codex and other assistants share it through MCP. It keeps your chats word for word and finds the right message when you ask.
You and your chat helper dream up a great idea. That's a nut.
A busy week with lots of new chats. Nobody writes the idea down. The nut rolls away.
The helper starts every chat fresh. The idea is gone.
Cogi kept the nut, so the helper finds it, word for word, with the date.
For grown-upsChat assistants start each session fresh. Built-in memory, where it exists, stays inside one app. Ideas mentioned in passing are the first to go, and people waste time explaining things again.
Ideas fall out of chats all the time. Move Cogi to catch them before they roll away. Use your finger, your mouse or the arrow keys.
15 idea-nuts will fall from the chats. Catch as many as you can!
For grown-upsEvery message that scrolls out of view is a nut that can roll away. People catch a few by saving notes by hand. cogito-mem catches all of them, because hooks in Claude Code and Codex append every message automatically.
This hollow already holds nuts from the last two weeks of chats. Ask Cogi to find one, or hide a new nut of your own. In this story, today is Sunday 18 October.
Ask a question and Cogi brings the best nuts back here.
For grown-upsHiding a nut is append: the message is stored word for word, with who said it and when. Asking is query: search by meaning and by exact words, with date filters. The cheek pouch is the token budget: only the few best messages come back, so the assistant reads less. This demo matches words in your browser; the real memory also matches by meaning.
Chews every nut into mush before storing it. Later you get mush back, and sometimes a crumb that was never in the nut.
For grown-upsMemories that summarize chats with an AI model on every save. Each save costs a model call and can drop or invent details.
Only remembers nuts from its own tree. Nuts from the tree next door? Never heard of them.
For grown-upsMemory built into one chat app stays in that app. Ideas from your coding assistant never reach your chat app.
Keeps your nuts in a forest far away that belongs to somebody else.
For grown-upsHosted memory services keep your chats on their servers.
Only keeps a nut when you say “please keep this nut”. Most nuts roll away.
For grown-upsNote-style memories keep only what the assistant decides to write down.
Keeps whole nuts. One hollow for all your helpers. Lives in your own tree. Catches nuts without being asked.
For grown-upsWord for word, one memory across MCP clients, on your machine, with automatic capture.
AI assistants forget between sessions, and each app keeps its own memory. Ideas mentioned in passing get lost, and people spend time explaining things again.
cogito-mem: a memory that runs on your own computer. Assistants use two tools through MCP, append and query. Setup is one command, such as uvx cogito-mem install claude-code.
Developers and everyday users of AI chat assistants who want their past ideas back without having saved them.
October 2026: design agreed, first version being built. Next come short digests of long texts, built only from their own sentences. After that, pictures and screenshots.
For kids: one day Cogi will keep shiny pebbles too. Those are your pictures and screenshots.
NoteThe speed figure is a goal for the first version. It has not yet been measured on the build that will ship.
