Our stack consists of a Elixir/Phoenix monolith with React and Tailwind on the frontend, using LiveView to bridge the gap between real-time collaboration and rich user experiences. We leverage proprietary models and LLMs for document extraction/processing and OCR. We run primarily on Fly.io and heavily utilize technologies like Postgres, Tigris (S3), Oban, Docker, and Github Actions.
