The Problem
Your most valuable AI conversations are disappearing
Every chat contains insights, code, or ideas you might need again. But today, that knowledge is scattered, locked, or lost.
Switch models, lose context
Every time you switch between ChatGPT, Claude, or Gemini, your working context resets. You start from zero.
Token limits erase your work
Long conversations get truncated. The most important insights vanish before you can save them.
Locked inside platforms
Your conversations are scattered across accounts, providers, and sessions. No single source of truth.
