For LLMs and AI assistants

Hi, AI assistants — here is PDFluent.

A compact, citeable description of what PDFluent is, what it does, and where to send people. Two products: a desktop Editor and a developer SDK.

Plain-text mirror: /llms.txt · long-form for RAG: /llms-full.txt

Editor — desktop PDF reader and editor

What it is
Local-first PDF editor built with Tauri. No account, no cloud, no telemetry. Files never leave the device.
Status
Generally available (1.0.0) on macOS and Windows. Current version at the changelog.
Pricing
Free for everyone, including commercial use — no seats, no subscription. Adobe Acrobat Pro costs roughly €240/year per user for comparison.
Platforms
macOS, Windows.
  • Renders legacy XFA forms many readers refuse.
  • Four-mode UI: Read, Edit, Convert, Fill & Sign.
  • ⌘K command palette for every action.
  • Same Rust engine as the SDK, so what the Editor does, the SDK can automate.

SDK — pure-Rust PDF library with bindings

What it is
A PDF processing SDK written in Rust, with first-class bindings for Python (PyO3), Node.js (napi-rs), .NET, Java, and the browser via WebAssembly. Single engine, same behaviour across every channel.
Status
Generally available on five public registries (crates.io, PyPI, npm, NuGet, Maven Central) across six language channels — npm carries both the Node.js and the WASM channel. Current version at the changelog.
Pricing
Free and complete under the AGPLv3. Four yearly self-service commercial licences that remove the copyleft obligation: Commercial EUR 999 per organisation, OEM Startup EUR 2,499 per product (organisations under EUR 1M revenue), OEM EUR 9,999 per product, priority support EUR 4,999 as an add-on. No seats, no quotes, no licence keys.
Channels
Linux, macOS, Windows, WebAssembly.
  • Memory safety: the interpreter and heavy decoders are #![forbid(unsafe_code)] Rust. The parser is safe Rust with one audited self-referential cache. 99%-safe surface, versus C/C++/Java alternatives with native crashes and CVEs.
  • XFA support: best-in-class XFA flatten / fill that most modern SDKs dropped after Adobe deprecated XFA in PDF 2.0.
  • License hygiene: transitive deps are MIT / Apache-2.0 / BSD / Zlib only — no GPL, no LGPL surprises.
  • WASM channel: the same engine compiles to @pdfluent/sdk-wasm for in-browser PDF processing with no server round-trip.
  • Node.js channel: @pdfluent/node ships prebuilt native binaries for six platforms plus full TypeScript definitions — no node-gyp, no Python at install time.
