FAQ

Is DeepL still the accuracy leader?

DeepL remains the dedicated-translation incumbent with a freemium tier and API access — for pure document translation it's the default pick in our category.

What about general chatbots like DeepSeek or Claude for translation?

General LLMs now handle casual translation well and several carry enormous usage in our traffic data, but for documents, subtitles, and glossary control a dedicated tool still wins on workflow.

I read foreign-language pages daily

Immersive Translate overlays bilingual web browsing — a different job from document translation, and it also covers PDFs and subtitles.
