Docling Studio is an open-source visual debugger for RAG pipelines built on IBM's Docling. Instead of treating document extraction as a black box, it lets you see exactly what happened: bounding boxes from OCR, chunks before embedding, retrieval results and fix what's wrong directly. Two weeks after public launch, the project has earned 60+ GitHub stars, direct engagement from the Docling team at IBM Research (including TSC chair Peter Staar), and inbound integration requests from companies. Scored 67.76 on HackerNoon's Proof of Usefulness : accurate for a young project, with Audience Reach as the next lever to pull.
