PaperPilot is a pure Rust PDF toolkit designed for AI agents and users, executing locally to ensure files never leave the device.
The tool supports multiple execution surfaces including an MCP server for Claude Desktop and Cursor, a CLI, a browser-based WASM interface, a Tauri desktop app, and a local REST API.
Current version v0.6 features include PDF organization (merge, split, rotate), optimization (compression), text extraction with pure Rust PaddleOCR, and security tools like watermarking and PII scanning.
The project is licensed under Apache 2.0 for the community edition and relies on lightweight dependencies such as lopdf, pdf_oxide, and rten.
