Score: 7.5/10 (Innovation: 8, Technical: 8, Documentation: 7, Utility: 7)

Omnesis is a private, self-hosted knowledge layer that indexes over 40 personal data sources (email, messages, health, finances, etc.) into a unified search index on hardware you own. It combines hybrid keyword/semantic search, a people graph, and a reference graph to power a sandboxed built-in agent and external agents via MCP, all while keeping data local and privacy-controlled.

Target audience: privacy-conscious users, developers, and power users seeking a local alternative to cloud-based personal assistants
