Open-source AI translation with an agent reflection workflow
Select text on any page, click the toolbar icon, and receive an improved translation that has already been reviewed by a second pass before it reaches you.
Works with any OpenAI-compatible endpoint, including local runtimes such as Ollama, so you can choose hosted speed or local privacy.
Edit the prompts used at each stage, including the reflection step, to shape voice, terminology, and output formatting.
The publisher declares that no data is collected or sold, and the code is open source for inspection.
