You've had hundreds of AI conversations. Where are they now?

Memdex auto-saves your AI conversations and brings the right context back when you need it — across ChatGPT, Claude, Gemini, and more.

Your best AI conversations are scattered everywhere.

HARD TO FIND

Hard to find when you need them.

You know you discussed it with AI last week — but which tool? Which conversation? Scrolling through dozens of chats to find it.

SILOED

Stuck in one tool.

A great conversation in ChatGPT can't help you when you're working in Claude. Each tool is its own silo.

REPETITIVE

Starting over, every single time.

New chat, same background. You re-explain your project, your preferences, your context — just to get back to where you were.

LOCAL FIRST

Your device. Your data. Period.

Encrypted. Local. Never uploaded. Never used for training. We couldn't read your conversations even if we wanted to.

Save it. Find it. Use it.
