Agentic automation platform for document-heavy enterprise workflows
Builds a high-fidelity structured map of an entire document packet, spanning emails, scans, spreadsheets, images and chat logs.
Agents execute multi-step business rules with cross-document validation rather than extracting fields from a single page.
Dynamically selects the best AI model per task instead of forcing a single provider across every workflow.
Generative AI output is auditable, verifiable and repeatable, with customer-controlled data storage including your own cloud.
AI-powered PDF editor for Windows, Mac and iOS
Summarize long documents, ask questions and get source-backed answers, or translate entire PDFs without leaving the app.
Edit text, images, links and backgrounds, annotate, add watermarks, and organize pages by inserting, deleting, rotating, cropping or extracting them.
Convert between PDF and 30+ formats while keeping formatting, and turn scanned documents into editable, searchable PDFs in 16+ languages.
A self-developed PDFium-based engine opens 100+ page files quickly, and built-in compression keeps file sizes manageable for sharing.
