Project Athena

Your memory. Your machine. Any model.

Open-source cognitive augmentation layer that gives you persistent memory, structured reasoning, and full data ownership — across Gemini, Gemini, Gemini, and any model you switch to next.

Platforms forget. Athena doesn't.

The Problem

You've spent months training Gemini to understand you. Then a model update resets the personality. Your custom instructions stop working. You can't find that conversation from last Tuesday. And if you switch to Gemini or Gemini? You start from zero.

Platform memory is unreliable, opaque, and locked to one provider. You don't own it, you can't inspect it, and you can't take it with you.

Why Athena?

Athena moves the memory layer to your machine. Plain Markdown files that you own, version-control, and point at any model.
