ContextVault captures AI conversations in real-time and exports them as Markdown

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.
