ChatVault — archive AI chats into a searchable knowledge base

Turn high-value ChatGPT/Claude conversations into a searchable personal knowledge base in one click

Problem

People have valuable discussions with ChatGPT or Claude, then days later can't find them in the history list; manual copy-paste destroys code block and table formatting. It's a high-frequency chore repeated over and over.

Solution

A browser extension that exports whole sessions or selected messages from major AI platforms while preserving code blocks, tables and heading levels; outputs Markdown/JSON/PDF and can commit directly to the user's own GitHub/GitLab repo as a versioned knowledge base.

Users

Heavy users of multiple AI chat tools—engineers and researchers who need to accumulate knowledge

MVP

Export from ChatGPT/Claude/Gemini; preserve code blocks and tables; one-click commit to the user's own GitHub repo; local full-text search over archived sessions

Revenue

Free tier limits platforms and archive size; Pro subscription unlocks PDF export, private repo sync and full-text search

Why now

Multiple AI platforms fragment conversations, and users increasingly want data ownership (their own repo); a single extension can deliver it without heavy backend work
