Bring Your Own Key

Translate the whole page, your selection, or text inside an image — with your own OpenAI or Gemini key.

LingoLens is a lightweight Chrome translator for full pages, selected text, and text in images. Bring your own OpenAI or Gemini API key — no Axonvale account, no first-party translation server, and no LingoLens subscription required for core translation. Your key and settings stay in the browser.

The extension is free. Translation uses your provider key: OpenAI bills API usage separately (ChatGPT Plus does not include it), and Google AI Studio offers a free tier with rate limits.
