Show HN: I built Knemora – An Open-source AI Second brain

Knemora is an open-source, local-first knowledge and agent platform with a native Second Brain graph, a portable Markdown Wiki, and local AI inference that runs without a mandatory cloud service, external LLM API, or vector database. The repository is prepared for its first public release, v0.1.0-alpha, and supports managed setup on macOS Apple Silicon with Node.js 24, local Qwen3-8B inference via llama.cpp, document ingestion, BM25 search, and backup/restore workflows.
