What does Memdex do?

Memdex is a Chrome extension that automatically saves your conversations with AI tools like ChatGPT, Claude, and Gemini. It stores everything locally on your device, then helps you find and reuse past discussions when you need them. Instead of losing track of valuable context, Memdex keeps all your AI interactions organized and accessible.

The tool works by detecting keywords as you type in any supported AI platform. When you mention something you've discussed before, Memdex highlights those words and lets you inject the full previous conversation with one click. This means you don't have to re-explain your project details or preferences each time you start a new chat. All data stays encrypted on your device—nothing gets uploaded to external servers.

Memdex is ideal for developers, researchers, writers, and anyone who regularly uses multiple AI tools for work. It's particularly useful for continuing complex technical discussions across different platforms, maintaining consistent project context, or simply avoiding the frustration of repeating yourself in every new conversation.
