Pieces

Pieces is an AI memory application that records computer activity to build a searchable history and provide context for AI assistants and workflows.

Pieces operates as an on-device AI memory layer that records computer activity in the background. It captures interactions from applications, including chats, emails, notes, and meetings, to create a searchable chronological timeline. Users search this history by time, topic, or source to recall past decisions or retrieve information from previous research. The software integrates with AI assistants via an MCP server, allowing context to flow into tools like Claude, Cursor, and Codex. It supports switching between models including Claude, Gemini, ChatGPT, and local options for generating summaries and recaps.
