Document AI agents that collect, extract, and cross-check documents
Read shared inboxes, pull attachments, chase missing pages, and split mixed uploads into the correct document types automatically.
Capture fields and table rows from statements, invoices, forms, and returns, each with its own confidence score for review.
Check each document against the others and against your rules, matching names, reconciling deposits to reported revenue, and flagging mismatches.
Send clean cases straight to your LOS or ERP by API or webhook, and route only failed checks to a single reason-attached queue.

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.
