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.
Turn PDFs into listenable multilingual audio summaries
Upload a PDF and get a condensed set of key points instead of a full-length read-through, so you capture the argument in minutes rather than hours.
Summaries are voiced in many languages with professional-sounding narration, making content usable for audiences that do not share a single language.
The end result is an audio digest you can listen to on the move, suitable for newsletters, class notes, briefings, and internal updates.
An API endpoint lets you convert PDFs to audio programmatically, so the same capability can sit inside your own app or content pipeline.
