High-precision document parsing and structured extraction API
Turn PDFs, scans, spreadsheets and slides into Markdown, HTML or JSON in fast, balanced or accurate modes, with optional word-level bounding boxes, chart data and figure descriptions.
Define the fields you need and receive JSON, where every value carries a citation pointing to the exact words or table cell it came from, plus a confidence score.
Detect natural boundaries between documents merged into one file, and compare parsing modes side by side on your own pages to choose on quality, price and speed.
Run the same pipeline in managed cloud, inside your own VPC, or fully air-gapped on-premises with no internet connection required.

Free AI-powered PDF editor, converter and reader for every device
Upload a PDF and ask questions in natural language, follow up on details and see which passages the answers came from. A separate chat mode works with YouTube videos.
Translate whole documents, including scanned and image-based PDFs, into 20+ languages while keeping the original formatting and layout intact.
Convert invoices, receipts, bank statements and purchase orders into structured, editable Excel files automatically.
Edit text and images, OCR scanned pages, convert to and from Office formats, then merge, split, compress, watermark, sign and annotate.
