> PaperPilot is an Apache 2.0, pure-Rust PDF toolkit whose single engine runs as an MCP server, a CLI, a local REST API, a desktop app and in the browser via WASM, so AI agents can merge, split, OCR and compress PDFs without uploading files; its latest GitHub release, v0.6.0, is marked as a pre-release.

## What changed

- The README describes one Rust engine exposed five ways: an MCP server (stdio), a CLI, a local REST API on localhost:7823 with Swagger docs, a Tauri + Svelte desktop app, and a WASM build that processes files in browser memory.
- For agents, the README says Codex, Claude Code, Kimi Code, Pi, Claude Desktop and Cursor connect to the same local stdio MCP server, and shows adding the paperpilot-mcp binary to claude_desktop_config.json to merge, split, OCR and compress PDFs.
- Features listed for v0.6: merge, split, rotate, reorder and extract pages, compress, plain-text extraction, pure-Rust OCR (PaddleOCR via rten), watermarking, signature validation and removal, PII scan, deep sanitize, and Excel to JSON or CSV.
- The roadmap in the README lists PDF to Markdown/HTML/JSON for v0.7, PDF to Word/Excel/PowerPoint for v0.8, and encrypt, sign, redact and forms for v0.9.
- The repository's Community Edition is Apache 2.0; the README says a separate Enterprise Edition (SSO, RBAC, audit logs, DLP) is developed separately. GitHub lists v0.6.0 (2026-10-24 UTC) as a pre-release with macOS, Linux, Windows and Android builds.

## In the source's words

> "PDF tools for your AI agent — and for you. Pure Rust. Runs locally. Files never leave your machine."

## What we have not verified

- We did not install or run PaperPilot; every feature listed comes from the project's README.
- We did not verify the no-upload claim for the browser version or check OCR quality or speed; the README's benchmark table is still a placeholder.
- The source publish time shown is the Hacker News post; the repository itself was created on 2026-09-28 and v0.6.0 was tagged on 2026-10-24 as a pre-release.
