Overview
What is Memdex?
Memdex is a Chrome extension that acts as a reusable local memory for your AI conversations. It automatically captures and saves your chat history across major AI tools like ChatGPT, Claude, and Gemini, storing them 100% locally and encrypted on your device. As you type a prompt in a new chat, Memdex highlights relevant keywords from your past discussions and allows you to inject that historical context into your current session with a single click, eliminating the need to re-explain background details.
