What's new

What changed, and since when.

No schedule to keep: we write when there is something to say. The most recent entries are at the top.

The new site, and all its pages

  • The home page tells the product's story with a brain of particles that scatters as you scroll, becomes a note and reconnects. On a phone it runs as smoothly as on a computer.
  • The pages about shared memory, the guides for connecting Claude, ChatGPT, Claude Code, Codex and Antigravity, pricing, what's new, privacy and terms.
  • The public documentation of the seventeen tools your AI uses in the brain.

The log becomes cards

  • Recent, favourites and shared all show the same row: title, branch, who wrote and when.
  • Every note says which branch it is in, including when it comes from a shared brain.

Connections is a guide, not a list

  • A step-by-step guide with screenshots for every program: Claude in four steps, ChatGPT in eight, plus Claude Code, Codex and Antigravity.
  • The page that authorises an AI states plainly what it will be able to read and write.

Dark theme, and emails on Cobrain's letterhead

  • The dashboard has a light/dark switch of its own, not just the system one.
  • The sign-in and sharing emails look like the product, in light and in dark.
  • The lists stay readable when narrow: the columns hold their place and wrap whole.

Two addresses: the site and the product

  • The public site lives at cobrain.space, the product at app.cobrain.space. The connector address for the AIs does not change.
  • Search says which brain each result is in, and the AIs pick the right brain by themselves.
  • Open a link without being signed in and you land on it after signing in, losing nothing on the way.

Units: clients, projects, whatever you follow

  • A folder with an index card becomes a unit: a client, a project, a student. Your AI opens it with a single command and receives the rules first, then the card, then the notes.
  • New tools for the AIs: start_session, list_units, create_unit and the guided brainstorm start_project.
  • You can share a folder even when it exists only because there are notes inside it.

The dashboard, rebuilt

  • The brain rail on the left, the working panel on the right, the log, ⌘K search, and the Recent, Favourites and All sections.
  • On the phone: a menu within thumb reach, actions that no longer overflow, and the brain switcher as a sheet from the bottom.
  • Sign-in rebuilt: a single page, with the stack and three promises.

The AIs get it wrong less, and you can see what they do

  • An AI adding a line can no longer wipe out the rest of the note by mistake: it is told to use append instead.
  • Search is five times faster.
  • Every AI call leaves a trace: tool, outcome, duration.
