HackLM Memory

Copilot forgets everything when you close the chat. HackLM Memory fixes that.

Free. No cloud. No sign-up. Works in VS Code out of the box.


How it works

1. Install the extension — one click from the VS Code Marketplace.

2. Chat normally — when something worth remembering comes up, the extension asks: "Save this to memory?" Click Save.

3. Copilot remembers — next session, next week, next month. Open a new chat and Copilot already knows your project's rules, quirks, and decisions.

Also on Open VSX. Support for additional editors is planned.
