Halo is a local-first AI assistant for Mac that provides daily briefings, autocomplete, call recording and summarization, and recall of past screen and call information.
All processing occurs on-device with no telemetry, ensuring privacy; captured data like frames and audio are deleted after processing.
Features include voice activation, automation for standing jobs, integration with MCP servers, and upcoming iPhone companion with end-to-end encrypted sync.
Halo is free forever, with optional Pro and Lifetime support for development, emphasizing user control and privacy with no cloud dependency by default.
