A unified knowledge base for your AI conversations. Search, learn, and reflect across Claude Code, Cursor, Codex, claude.ai, ChatGPT, and more.

From the creator of [claude-reflect](https://github.com/BayramAnnakov/claude-reflect) (300+ stars) - this is the evolution: a native macOS app that aggregates *all* your AI conversations, extracts learnings, and helps you build persistent context.

What It Does

**The problem**: You use Claude Code, claude.ai, ChatGPT, and other AI tools daily. Context is scattered. When you discover a preference in one tool, you lose it in another. You keep re-explaining the same things.

**The solution**: Retain aggregates all your AI conversations into a single searchable knowledge base. It automatically extracts corrections and preferences, then exports them to `CLAUDE.md` so Claude remembers what you taught it.

Key Features

• Multi-source sync: Auto-sync from CLI tools (Claude Code, Codex, Cursor, Gemini CLI, OpenCode, GitHub Copilot CLI), manual sync from claude.ai and ChatGPT (cookie-based)
• Instant search: Full-text search across 10k+ conversations with FTS5
• Learning extraction: Automatic detection of corrections ("no, use X instead") and preferences
• CLAUDE.md export: Export approved learnings so Claude remembers your preferences
• Auto-updates: Automatic update notifications via Sparkle framework
• Local-first: All data stored locally. Optional cloud features (web sync, AI analysis) connect to external services when enabled.
