WeTrans is an offline-first application. All project files, translation memories, and termbases are stored on your local device. When using local AI models via Ollama, your entire pipeline is 100% physically private — no data ever leaves your computer.
We currently offer a deeply optimized version for Windows. The macOS version is in active development — core engine adaptation is complete and UI adjustments are underway. Expect a release next quarter.
After the 15-day trial, you won't be able to create new projects or export files, but all your data remains safely on your machine. Purchasing a license key instantly restores full AI-powered functionality.
WeTrans integrates with OpenAI GPT-4o, Anthropic Claude, Google Gemini, DeepSeek, Zhipu GLM, and any model running locally via Ollama. You can switch models per-project or even per-segment.
WeTrans starts at $9.9/month for the Starter plan and $19.9/month for Professional — roughly 1/4 the cost of Trados Studio subscriptions ($40-54/month). WeTrans also includes AI translation agents and a built-in subtitle workbench at no extra cost.
WeTrans supports Word (DOCX), PDF, PowerPoint (PPTX), InDesign (IDML), and subtitle formats including SRT, ASS, and VTT. It intelligently parses complex layouts and preserves original formatting on export.
