The nuance specialist
For professionals and students working in European languages, DeepL is usually worth the narrower language list.
DeepL made its name by producing translations that sound less robotic than its competitors, and that advantage is most noticeable in European languages. German, French, Spanish, Italian, Dutch, and Polish all come out sounding remarkably natural, which is why it is the go-to choice for business emails, reports, and academic papers.
The web app is particularly strong. You can upload whole documents, build custom glossaries, and choose between formal and informal tone. These features make DeepL the best tool for business document translation, even if it does not have the widest language coverage.
On mobile, DeepL is more limited. There is no offline mode, and the voice/conversation features are basic. It also skips some languages entirely, including Icelandic and Hindi. If your needs are European and professional, DeepL is hard to beat. For travel or low-resource languages, look elsewhere.

Screenshots below were captured by our automated test rig on a real iPhone running the current App Store build.
DeepL's screen is just two boxes. But look at what it did: we typed a polite English request, and without being told, it chose the polite German form 'Könnten Sie' — the way you'd address a stranger — instead of the casual form you'd use with a friend. Getting that right is DeepL's whole reputation. The Alternatives button under the answer shows other ways to phrase it, so you can pick the tone you want.
Paste an email you wrote in German or English, and DeepL Write corrects the grammar and suggests smoother wording. It's a writing helper living inside a translation app, and none of the other apps we rank has one. If you write in a second language for work or school, this tab might be the reason to pick DeepL.
DeepL used to be weak at spoken conversation — this new mode is the fix. Each person gets a microphone and, unusually, a keyboard too, so a shy speaker can type while the other talks. The middle button listens and figures out which language it heard automatically. It's newer and less proven than Google's or Microsoft's conversation modes, but it means DeepL is no longer just a typing app.
For European languages and formal writing, yes. For travel, camera translation, and rare languages, Google Translate is stronger.
No. DeepL requires an internet connection on both mobile and desktop.

There are about 7,100 living languages. Translation apps cover a few hundred at most. Here is how coverage maps to population, and how big the remaining gap really is.
