Memdex

Memdex is a Chrome extension that works like a reusable local memory for your AI conversations. Instead of starting from scratch every time, it automatically captures and saves your chat history across major AI tools including ChatGPT, Claude, and Gemini, so your context is always ready when you need it.

Privacy is built in: everything is stored 100% locally on your own device and encrypted, meaning your conversations never leave your computer. You stay in control of your data while still getting the convenience of a searchable memory across all your AI tools.

When you start typing a prompt in a new chat, Memdex highlights relevant keywords drawn from your past discussions. With a single click, you can inject that historical context into your current session, eliminating the tedious need to re-explain background details over and over again.
