Docling Studio shows you exactly what a document parser sees, drawing a colored box around every title, paragraph, table, and picture it extracts from your PDFs. Import a PDF, run an analysis, and the result opens with three linked panels: the document tree on the left, the paged preview in the center, and the selected element on the right with its type, page, position, and text or table. Click any box on the page and the same element lights up in the tree and properties panel as other boxes fade away. The layers bar counts each element type and toggles boxes per type, or hides them all to reveal the bare page. You can analyze several documents at once from the list, watch progress percentages on long files, and queue work three analyses at a time. Ask a question and a local model answers from the document, with a reasoning timeline that links each step back to the passage it read. Finished results download as the original PDF, clean Markdown, or Docling JSON for downstream pipelines. AI agents connect over MCP to read and cite your documents, and an optional connection to your own Docling Serve server handles heavier parsing loads.
