PdfTogether pairs a clean-room Rust PDF engine with real-time synchronization, giving you desktop speed and total data ownership.
Work together simultaneously. Powered by Conflict-free Replicated Data Types (CRDTs), every comment, highlight, and annotation syncs instantly without merge conflicts or lost updates.
Your confidential contracts and reports remain strictly on your own device. No forced cloud uploads, no mandatory account sign-ins, and zero third-party AI training on your documents.
Edit text directly, add vector shapes, fill and build interactive AcroForms, organize, crop, rotate, split, and merge pages with instant sub-pixel rendering accuracy.
Cryptographically sign documents with PKCS#7 / PAdES standard verification. Perform permanent vector redaction that genuinely strips sensitive content and hidden metadata from the PDF stream.
Transform scans and photos of documents into clean, searchable, selectable text automatically. Runs 100% locally on your computer with no external API calls or fees.
Automate batch document tasks using pdftogether-cli and connect AI agents seamlessly via Model Context Protocol (MCP) tools for automated drafting, review, and verification.
