A downloadable tool for Windows

Hi! I'm VannDoc, and I translate Ren'Py visual novels (into Russian). However, as you can see, I'm now doing more than just translations—I'm also developing this program.

About the program


RAT (Ren'Py Auto Translator) is a lightweight and fully automated localization tool designed to make translating Ren'Py visual novels as effortless as possible. Whether you are a localizer trying to speed up your workflow or a player who wants to read a new release in your native language, RAT handles all the technical heavy lifting for you.

Key Features:


  • Smart Auto-Unpacking: The tool automatically extracts and decompiles game archives and .rpyc script files—no third-party software required.
  • Translation Engine Selection: You can choose the translation engine that will be responsible for translating your visual novel. Seamlessly switch between various available engines. You can also set a backup engine to automatically catch any phrases if the primary one hits a rate limit.
  • Safe Code Parsing: RAT is built to translate only the dialogue and UI text. It carefully protects game variables, code logic, and formatting tags to ensure the game remains fully playable without crashes.
  • History & Backup System: Keep track of the visual novels you've modified. If anything goes wrong, you can restore original scripts, fonts, or full game backups with a single click.
  • Modern Interface: A clean, fast, and user-friendly UI that makes the entire translation process clear and intuitive.

Feedback & Bug Reports:

If you encounter any bugs in the program, notice mistakes during the translation process, or have any suggestions for improvement, I would gladly welcome your feedback! I plan to gradually improve the tool and fix issues in upcoming updates.
