Membase
A free Chrome extension. Capture what matters as you chat, then send exactly the context you need into whichever AI you are using — without explaining yourself from scratch every time you switch.
Sync a whole conversation, or save the one answer worth keeping, from inside the chat you are already in.
Pick the context for the question you are about to ask, instead of pasting your whole history and hoping.
The key is derived on your machine and never leaves it. This is the surface where that is literally true — the extension encrypts before anything is sent.
The same memory in every one of them, so moving from one to another costs you nothing.
The extension is one way in. What it captures lands in Membase Web, which you can read, correct and point other AI at — including the coding agents you run and the ones you build. The extension is how your memory reaches the browser; the web app is where it lives.
