Rekall

What it does

Rekall acts as a persistent second brain for AI tools, solving the problem of session-based amnesia. It automatically extracts knowledge from your interactions and stores them as embeddings in a local SQLite database, allowing AI agents to recall decisions, research, and preferences by meaning rather than exact keywords.

Tools

• recall: Performs hybrid keyword and semantic search across all stored memories.
• remember: Manually stores a specific fact, preference, or decision with automatic deduplication.
• forget: Archives a memory via soft-delete, making it recoverable if needed.
• list_memories: Browses stored information by type, project, or status.
