Google Translate

★4

Google Translate covers 133 languages at no cost. The only tool that comes close on language breadth. Reddit recommends it for quick checks, rare languages, and high-volume casual translation.

Best For:

Reddit's Verdict: DeepL vs ChatGPT vs Google Translate

The community consensus across r/translator and r/languagelearning: these three tools are not competing for the same users. DeepL wins on European language quality. ChatGPT wins on context and Asian languages. Google Translate wins on coverage and cost.

One r/translator thread: "GPT translates Japanese articles into much more fluent English than Google. It gets the implicit subjects and adjusts formality level appropriately." Another on DeepL: "For EN-DE technical docs, DeepL translates better than most humans."

The practical Reddit workflow used by professional translators: "Quick pass with Google to understand unfamiliar text, then DeepL or ChatGPT when accuracy matters."

When DeepL Wins

DeepL holds the highest BLEU scores for European language pairs: 64.5 for English to German, 63.1 for English to French, outpacing ChatGPT (62.1) and Google (48.3) significantly. For professional documents in European languages, format preservation is also better than any competitor.

The CAT tool integration (Trados, memoQ) is the key feature for professional translators. DeepL Pro feeds directly into the tools professionals already use, which is why it dominates the professional translation community despite the subscription cost.

Privacy: DeepL Pro does not use input for training and is hosted on EU servers, which matters for legal, medical, and business documents subject to GDPR.

When ChatGPT and Claude Win

For Japanese, Chinese, and Korean translation, ChatGPT consistently outperforms DeepL in Reddit comparisons. One user: "DeepL cannot handle Japanese implicit subjects and honorific levels. ChatGPT gets both right most of the time."

Claude (Anthropic) earns separate mentions in r/translator for formal and technical documents. Its large context window means it handles entire long-form documents without the chunking workflow ChatGPT requires for very long texts. Reddit users describe Claude as "slightly better than ChatGPT at formal content and consistency."

Full Book Translation: A Different Category

For translating entire books, the Reddit recommendation in r/indieauthors is BookTranslator.ai rather than DeepL or ChatGPT. BookTranslator.ai handles EPUB files with formatting retention, supports 99+ languages, and costs $5.99 to $9.99 per 100,000 words.

DeepL struggles with large books due to API chunking limits that cause silent truncation and formatting issues in Word files. ChatGPT requires manual chunking for anything over 100,000 words.

Frequently Asked Questions

Yes for European languages. DeepL scores 64.5 BLEU for English to German vs Google's 48.3. For Asian languages and rare language pairs, Google or ChatGPT is often better. DeepL covers only 33 languages vs Google's 133. For European professional translation, DeepL is the clear community pick.

DeepL for European Languages, ChatGPT for Asian Languages and Idioms, Google Translate for Free Coverage.

The Reddit consensus on AI translation is clear: no single tool wins for all language pairs and use cases. DeepL dominates European language professional translation with the highest benchmark scores and the best format preservation. ChatGPT and Claude handle idioms, context, and Asian languages better. Google Translate covers the widest range of languages for free. Most power users on Reddit use two or three of these tools depending on the content type.
