Writing business emails in English, French, or Spanish costs time in many offices every day. DeepL, ChatGPT, and Google Translate translate such emails today in seconds. However, the three tools differ significantly in tone, cost, and handling of company data.

DeepL, ChatGPT, and Google Translate approach the task differently

All three services automatically translate German text into a foreign language and vice versa. However, they differ in price, accuracy for the German language, and handling of entered texts. The following overview summarizes the most important practical differences.

ToolPriceSuitability for GermanData Protection NoteAccess Method
DeepLFree for short texts; Pro subscription tiered from a low two-digit Euro amount per user per monthOriginating as a language service in Cologne, it has been regarded for years as a reference for formal German business toneAccording to the provider, the Pro version contractually waives storage and training; the free version may use texts for training purposes according to the privacy policyWeb, Windows and Mac app, browser extension, add-in for Word and Outlook
ChatGPTFree basic version; Plus costs around 23 Euros per month, the entry-level plan Go around 8 EurosTranslates contextually and adjusts salutation and tone on request, but reacts more sensitively to unclear instructionsThe use for training can be turned off in the data controls; business plans do not use inputs for training according to the providerWeb, app for iOS and Android, desktop app
Google TranslateFree, no subscriptionFast and reliable for everyday sentences, often less precise than DeepL for technical terms and politeness formsWith a logged-in account and activated web and app activity, Google saves translations in the account historyWeb (translate.google.com), app, Chrome extension, Google Docs

Everyday usefulness is reflected in speed, tone, and post-editing

DeepL is suitable for the quick one-to-one translation of a finished email, without any further instructions. The tone usually remains factual-formal, as is customary in German business communication.

ChatGPT also translates but can additionally rephrase an email on request, for example, “a bit more polite” or “shorter.” This idea of improving text through free instructions is now also pursued by the writing assistant in Gmail – but for all three tools, a short, clear instruction provides the most reliable results.

Google Translate excels in speed and simplicity, for example, to quickly understand an incoming foreign-language email. It is less suitable for one’s own outgoing business correspondence because salutation and politeness forms are coarser than with DeepL or ChatGPT.

Price, access, and requirements determine the choice

For occasional translations, the free versions of DeepL and Google Translate are sufficient, without the need for an account. For regular business correspondence, a paid subscription is usually worthwhile, as it allows for longer texts, entire documents, and a contractual waiver of data storage.

ChatGPT typically requires the paid plan for daily use in the office, as the free version limits the number of messages and text length. Anyone inserting names, contract details, or customer data into an email should check internal guidelines beforehand; a Pro or Business plan with a storage waiver is the safer choice than a free version.

All three tools do not replace a verified professional translation. For contracts, technical terms, or legally binding commitments, a second, human review remains sensible – an automatic translation can shift nuances without the error being noticeable at first reading.

Frequently asked questions

Does translating business emails with these tools cost anything?

Google Translate is continuously free. DeepL and ChatGPT offer free basic versions; for longer texts, more features, and a contractual data protection waiver, a paid subscription is required.

Is an account or subscription required for use?

For individual, short translations, web access without an account is sufficient for all three services. An account or subscription is required for saved histories, longer texts, or corporate rates.

Are the tools available in Germany and the EU?

Yes, all three services are available in Germany and the rest of the EU. DeepL operates its servers in Germany according to its own statements.

Can company or customer data be entered?

Are there alternatives to the three tools?
