fortemi

Self-hosted AI knowledge base with hybrid semantic search (pgvector + FTS + RRF), MCP server, multi-provider LLM inference (Ollama, OpenAI, OpenRouter, llama.cpp), multimodal ingestion (vision, audio transcription, speaker diarization), and knowledge graph. Rust + PostgreSQL. Maintained by Fortemi on GitHub, where it has earned 25 stars from the community.

It's actively developed around ai, embeddings, hybrid-search, and is a solid reference for anyone building with these tools.
