Why DeepL

The European-language gold standard — built specifically for translation

DeepL isn't a general AI model wired up to translate — it's a translation-specific neural engine trained on parallel corpora. For European language pairs especially, that focus produces the most accurate, idiomatic output of any provider. With AutoPoly, DeepL runs directly inside Polylang.

Specialist, not generalist

Trained specifically for translation — fewer errors on common phrases than general AI models.

#1 ranked for EU languages

Gold standard for English ↔ German, French, Spanish, Italian, Dutch, and Portuguese pairs.

Formality control

Flip between formal and informal "you" — essential for German, Spanish, French, and other tu/vous languages.

Glossary-aware

Brand terms, product names, and technical vocabulary stay consistent across every translation.

Reviews

What developers say about AutoPoly

Real reviews from real users using AutoPoly with AI translation providers.

★★★★★

I tested the "Automatic Translations for Polylang" plugin for a project. The plugin is well-built and does exactly what it promises. You can try their plugins with absolute confidence!

★★★★★

I had an issue with some configurations during setup, but the support team helped resolve it immediately.

★★★★★

This plugin is doing a better job for me with translation than other AI plugins I tried before on my website. I just plug it with Gemini Pro and I've paid less than $1 for massive translates on my website with the 2.5 Flash model.

DeepL has a free tier (500,000 characters per month) and a paid tier starting at €5.49/month plus €20 per million characters beyond the free monthly allotment. For most small sites, the free tier is enough.

DeepL covers 32 languages and is consistently rated #1 for English ↔ German, French, Spanish, Italian, Dutch, Portuguese, Polish, and Russian. For pairs outside Europe, Google Translate or OpenAI is often a better fit.

DeepL is a specialist translation engine, not a general AI — its model is trained specifically on parallel translation data rather than general web text. The result is fewer errors on common phrases, better idiomatic handling, and more consistent terminology.

Yes — DeepL's glossary feature lets you define brand names, product names, and technical terms that DeepL preserves consistently across every translation. Useful for keeping product names in English even when translating descriptions.

Yes — DeepL supports a formality flag for languages with t/v distinction (German, Spanish, French, Italian, Dutch, Polish, Portuguese, Russian). Pick formal or informal in the plugin settings.
