Docling Studio is a visual layer on top of Docling, the document extraction engine. The idea is simple: give users a way to see extraction results for debugging, quality analysis, and understanding how the pipeline actually works.
Document extraction is a critical building block for AI projects, especially in RAG contexts. But when something goes wrong in the extraction, you need to see it, not just read JSON. You could script a quick viewer with pdf.js, but you’d be re-implementing coordinate transforms, element filtering, and result navigation from scratch, and you’d lose the native connection to DoclingDocument structures that makes inspection actually useful.
