Bowerbird
Bowerbird: Desktop and web application for querying local document collections with verified model citations.
Bowerbird is an open-source alternative to NotebookLM that keeps your files on your machine. Users add PDFs, Word documents, EPUBs, web pages, YouTube captions, and audio recordings to local notebooks stored as plain folders. It performs transcription, OCR, and search locally using SQLite and EmbeddingGemma. Answers come from models like DeepSeek, OpenAI, Anthropic, or local Ollama instances, complete with citations that check whether quoted words appear in the sources. It runs as a local web server, desktop app, or Android application.
