Mantle: Open-Source Self-Hosted AI Memory & Second Brain

CurieuxExplorer · x · 2026-08-09

Introduces Mantle, an open-source, self-hosted tool designed to give AI persistent memory instead of treating every conversation as isolated.

It can ingest emails, files, notes, calendars, and other personal or company knowledge into one structured memory. Mantle works proactively in the background via scheduled routines—such as organizing incoming information, surfacing forgotten items, or creating briefings. It can also expose its knowledge to other AI tools via MCP and be specialized into separate brains for different teams.
