What it is
Monolithos is a personal agent operating system built around user-owned memory and continuity. It connects memory, AI tasks, writing and cross-device work into a system where you own the underlying data and control what becomes memory.
The platform includes eight modules—Memory, Flow, Black Hole, Minutes, Codex, Prism, Audio and Facet—all sharing one vault you own, built on Markdown and YAML files. It works offline for vault access and editing, with local Minutes transcription, while cloud AI processes context for requests you choose to make. Your private-domain content stays out of cloud AI context.
Monolithos is compatible with existing Obsidian vaults and runs on macOS, iOS and Windows. The system emphasizes ownership and portability: files remain readable as plain Markdown with YAML frontmatter, usable with any text editor, on any platform, with no vendor lock-in possible.
