Parallax: self-hosted video intelligence with transcripts, chapters, and cited answers

Parallax is a self-hosted platform that ingests video up to two hours long and produces timestamped transcripts, chapter segmentation, summaries, key-point extraction, and question answering grounded in citations. It runs Faster-Whisper for transcription, 384-dimensional sentence-transformer embeddings in PostgreSQL with pgvector, Celery and Redis for async task queues, and a React 18 front end. The author reports 101 Pytest and 25 Vitest tests passing with no static analysis errors. The project is local only and not cloud hosted.
