Translate EPUBs
with AI, locally.
Drop a book, get it back in your language. Libyx supports 40+ languages and runs entirely on your computer — your books, your API keys.
Version 0.1.0 · macOS 12+ · Windows 10+ · Free
The complete app — drop an EPUB, choose a model, start translating.
How it works
Drop your EPUB
Drag and drop a file. Nothing leaves your computer except the text sent to your chosen AI model.
Choose a model
Claude, GPT, Gemini, Mistral, or any OpenRouter model. Pick by quality and cost. Batch mode delivers overnight at half price.
Get your translation
A complete EPUB you can read in your reader of choice. Optional polish pass for literary quality.
Bring your own API key
Libyx is not a subscription. You pay the AI provider directly. A typical book costs under €1 in batch mode, sometimes a few euros for the highest-quality models.
Windows users — read this first
The Windows version is currently in development. When it becomes available, Windows Defender SmartScreen may show a warning because the installer is not yet signed with a code-signing certificate. To proceed:
- Click More info in the SmartScreen dialog.
- Click Run anyway.
- The app will open normally.
We plan to add code-signing in a future release to eliminate this warning.
✓ macOS — signed and notarized
The macOS version is signed with an Apple Developer ID certificate and notarized by Apple. Gatekeeper will allow it to open without any security warnings.
