- Contextify is a private searchable timeline that records Claude Code and Codex sessions.
- It works by watching both tools and storing all conversations in a local, searchable database.
- Users can view session summaries in real-time to skim or follow along with AI work.
- Full-text search allows finding specific commands or solutions from past conversations quickly.
- On macOS 26 (Tahoe), it generates LLM summaries locally using Apple Intelligence, keeping data private.
- On macOS 15 (Sequoia), a Lite Mode offers timeline and search without AI summaries.
- It operates entirely on-device with no accounts needed, but Cloud Sync enables cross-device search and backups.
- Users can also self-host on their own infrastructure and control data synchronization.
