What Eigma is

Eigma turns your conversations with an AI assistant into a personal wiki you actually remember.

An assistant can explain something well, and almost none of it survives you closing the tab. A week later you remember that you understood the thing, but not the thing itself, and what you do recall is often subtly wrong. Eigma saves the part worth keeping, files it under the right chapter, and asks you about it again before you forget.

Your knowledge as a map. Each page is a point of light, and its brightness shows how well you still remember it rather than how recently you opened it. Pages you have internalized stay bright; pages you are forgetting go dim.

Eigma connects over MCP, so it works inside the assistant you already use — ChatGPT, Claude, and coding agents like Claude Code and Codex. Your assistant does the thinking; Eigma keeps the result. The app is available in English, 中文 and Deutsch. → eigma.app

Connect it to your assistant

Setup takes about a minute, and you do it once per assistant.

Create your Eigma account first, at eigma.app. Partway through, you will be

asked to sign in, and your pages will go to whichever account you sign in with.

ChatGPT — its own address

https://my.eigma.app/api/mcp-chatgpt
  1. Settings → Plugins
  2. Turn on Developer mode. The option to add your own plugin does not appear until you do.
  3. Browse plugins → + to add one
  4. Name it Eigma and paste the address into the server URL field
  5. Sign in with your Eigma account and approve the connection

Claude, Claude Code and Codex — one shared address

https://my.eigma.app/api/mcp

Claude: Customize → Connectors → + → Add custom connector, paste the address, Add, then sign in.

⚠️ Then open a chat, click the + at the bottom left, choose Connectors, and switch Eigma on. Claude uses only the connectors that are switched on in that particular conversation. If Eigma looks connected but nothing happens, this is almost always why.

Claude Code:

claude mcp add --transport http --scope user eigma https://my.eigma.app/api/mcp
claude mcp login eigma

Codex:

codex mcp add eigma --url https://my.eigma.app/api/mcp
codex mcp login eigma

The login command opens a browser window so you can sign in and approve. Afterwards, run claude mcp list (or /mcp in a chat) to confirm the connection: worth doing, because a failed connection fails silently.

Then, in any chat: "organize this into Eigma". Your assistant turns the conversation into pages, files each page under the right chapter, attaches a few questions to it, and sends the result to your review inbox.
