Shared memory for AI coding agents

One project.
One shared brain.

Give Claude Code, Codex, and Cursor a shared record of your team's decisions.

npx klypix-mcp install
How it works

Two agent sessions on one PC share a brain, see declared file overlaps, and leave notes for each other. A note waits for the receiving session’s next supported action. Want it sooner? KLYPIX asks first, and only on your OK reopens a closed Claude Code or Codex session in a new terminal.

  1. Two sessions. One brain. Claude Code and Codex on one PC, reading brain.klypix in your repo.
  2. Same file? Each gets a heads-up. Advisory. Nothing is blocked.
  3. Leave a note for a closed session. KLYPIX keeps it for up to 7 days. You relay nothing.
  4. Want it sooner? KLYPIX asks first. Say yes and it reopens Codex, with the note. Nothing opens without your OK.
  5. All on your machine. One brain file in your repo, not one tool’s private notes.

Voice-over: Share. Warn. Hand off. Two agent sessions on one PC, Claude Code and Codex, read one brain file in your repo. Both declare the same file? Each gets a heads-up. Nothing is blocked. Codex closed for the day? Claude leaves it a note, and KLYPIX keeps it for up to seven days. You don't copy anything across. Want it sooner? KLYPIX asks you first, then reopens Codex with the note. Nothing opens without your OK. All on your machine.

Share the brain once. While it is open in Klypix, each teammate's copy syncs by itself and merges cards from both PCs.

  1. Your team works on more than one PC. Each PC keeps its own copy of the project brain.
  2. Share the brain once. An encrypted copy goes to the KLYPIX cloud. Invite the teammates who edit it.
  3. It syncs by itself. When you open the brain, when an agent writes to it, and when you come back to it.
  4. Your teammate’s agents start with it.
  5. Cards from both PCs are merged. The dot on each PC shows whether its copy is in sync.

One project. One shared understanding.

Voice-over: When a team shares a project, the files get shared and the reasoning stays on one machine. Your teammate's agent starts cold on what you settled last week. KLYPIX shares the brain: every machine holds the whole brain, not a link to it. Share it once, invite the teammates who will edit it, and each copy syncs by itself while that brain is open in KLYPIX. Their agents can pick up the current decision, cards added on both PCs are merged, and a dot on the sync button tells you if your copy is current. One project. One shared understanding.

A fresh session.
A familiar project.

Your code stays in Git. Its recorded understanding lives beside it.

The same new task, with and without the recorded decision.

Connect your tools.

Run the installer in your project. Connect a supported coding tool through MCP.

npx klypix-mcp install

Record one decision.

Include the reason behind it.

brain.klypix

Try a new session.

Ask a supported agent what was decided. Inspect the returned context.

One command.
Whatever you start from.

Run it once in each project, on each machine. It needs Node 20 or later.

  1. One command in your project. It creates brain.klypix if there is none, and connects the AI tools it finds.
  2. Already have a brain? A teammate committed brain.klypix? Install keeps it as it is and connects your tools.
  3. Several AI tools, one brain. Claude Code reads and saves by itself. In tools with MCP, the agent calls the brain.
  4. Two sessions on one PC? Sessions can list the files they will touch. Same file? Both get a heads-up.
  5. A teammate on another PC? Commit brain.klypix with your code. Once each teammate runs install, a pull merges both sides’ cards.
  6. Check it any time. npx klypix-mcp doctor

One project. Many agents. One current understanding.

Voice-over: You brief one tool, then the next, then the one your teammate prefers: the same project explained three times. One command changes that. Run it inside your project: KLYPIX creates the shared brain if there is none, then connects the supported tools it finds on this machine. Claude Code reads it and writes to it by itself; in other tools, your agent calls it. Two sessions on the same PC can each declare the files they are about to touch; name the same one and each gets a heads-up, advisory, nothing blocked. Commit it with the code; after each teammate has run install, a pull brings both copies together. Different tools, one current understanding.

A project with no brain yet.

Install creates brain.klypix, wires the AI tools it finds on this PC, and starts the brain once to confirm its tools answer.

A repo that already has a brain.

A teammate committed brain.klypix? Run the same command. It keeps that brain as it is and connects your tools to it.

Several AI tools on one PC.

They share the project's one brain. Claude Code reads it when a session starts and saves decisions by itself. In tools with MCP, the agent calls the brain's tools.

Two sessions at once.

A session can declare the files it expects to change. If two sessions on this PC declare the same file, both get a heads-up: the second at once, the first on its next Klypix action. It warns; it never blocks.

A teammate on another PC.

Commit brain.klypix with your code. Once each teammate has run install in their copy, a pull merges both sides' cards. Or share the brain from the Windows app.

Both ways, step by step

What each tool gets

Claude CodeReads the brain when a session starts and saves decisions by itself.
Codex, Cursor, VS Code (with GitHub Copilot), Cline, Gemini CLI, AntigravityMCP config and an always-on rules file that tells the agent to call the brain. Nothing runs by itself.
Windsurf, AiderProject rules only.

Install wires the tools it finds on this machine. Overlap warnings stay on one machine; what crosses machines is the committed brain.klypix file, or Brain Sync in the Windows app.

A shared record.
A clearer next move.

Decisions stay current.

An explicit correction supersedes the old answer and preserves its history.

Overlapping work becomes visible.

Declared file overlaps surface as warnings between supported sessions on the same machine.

You stay in the loop.

Open the brain in Klypix to read, connect, and correct the project record.

Get the Windows workspace
Correct it once, through your agent. Later answers show the fix, and the old decision stays as history.

A few good questions.

Is it free?

Everything is free during beta. No card is required, and Klypix will not charge automatically. You will receive at least 30 days notice before paid plans begin.

Which AI tools can use the brain?

Claude Code, Codex, Cursor, and other supported tools connect through MCP or the CLI. Integration depth varies by host. Your agents run in the tools you already use.

Can I take my space out?

Yes. Your .klypix file is a documented ZIP on your disk. Export to Markdown or JSON Canvas, with embedded files extracted alongside.

What does a new brain know?

Only what you or your agent record. Klypix does not invent your project history. Useful context grows as decisions, corrections, and evidence are captured.

Can teammates use it on different computers?

Yes. Share the brain once from the Windows app and invite your teammates. While Klypix has the brain open, each copy syncs by itself through an encrypted cloud copy, and cards from both sides are merged on each PC. You can also commit brain.klypix with the repository. Live presence and file-overlap warnings are currently limited to the same machine.

Does Klypix replace Git or run my agents?

No. Git versions your code; your coding tools run your agents. Klypix keeps the recorded decisions, corrections, and evidence beside the project.
