The ProblemYour most valuable AI conversations are disappearing<br>Every chat contains insights, code, or ideas you might need again. But today, that knowledge is scattered, locked, or lost.

Switch models, lose context<br>Every time you switch between ChatGPT, Claude, or Gemini, your working context resets. You start from zero.

Token limits erase your work<br>Long conversations get truncated. The most important insights vanish before you can save them.

Locked inside platforms<br>Your conversations are scattered across accounts, providers, and sessions. No single source of truth.
