durability
bus factor = how many people it takes to cover more than half the commits (6 months). 1 is a solo project; higher means the work is spread across a team. top-author share is the single busiest author's slice of those commits.

why it's a big deal
- Gives researchers a self-hosted alternative to Google's Notebook LM, keeping documents and chat local rather than on a vendor cloud.
- Handles PDFs, videos, audio, web pages, and Office docs in one place, with full-text and vector search plus context-aware chat over that material.
- Supports 18 or more model providers including OpenAI, Anthropic, and local runtimes like Ollama and LM Studio, so users pick their own models and avoid lock-in.
under the hood
- Splits into two services deployed via Docker Compose; a Python FastAPI backend with a Next.js and React frontend, reachable on localhost:8502.
- Uses SurrealDB for persistence and LangChain to orchestrate model calls across the supported providers.
- Exposes a REST API for programmatic access, and includes multi-speaker podcast generation plus support for reasoning models such as DeepSeek-R1.

understory
Output and attention are roughly in balance.
- output, commits & releases
- clout, star velocity
output = commits & releases; clout = star velocity, both 0 to 100 monthly indices; the gap where output runs above clout is the understory. The understory →
