Our verdict
DeepL suits people who translate text and documents and want glossaries, tone control, or stronger data terms on paid plans. The trade-offs: the free version is capped and uses content for training, and Trustpilot ratings are low (2.4/5), mostly over billing and support.
Best for: People translating documents and work emails across English, German, Vietnamese and many other languages
Skip it if: Heavy translators who do not want to pay: the free version covers only 50,000 characters per month
Pros
- High app-store ratings: 4.8/5 on the US App Store (13,284) and 4.7/5 on Google Play (437K)
- Translates files, images and speech; glossaries and tone settings on paid plans
- Paid plans do not use texts for training and do not store them permanently
Cons
- The free version uses submitted content for training and is capped at 50,000 characters per month
- Trustpilot 2.4/5 (790 reviews): reviewers complain about charges after trials, refunds and slow support; these are unverified accounts

Experience & key features
What is DeepL?
DeepL is a machine translation service from DeepL SE, based in Cologne, Germany. The translation system was built within Linguee from 2016; on 28 August 2017 DeepL Translator launched with seven European languages and Linguee's company was renamed DeepL GmbH. It later added Write (a writing assistant, public beta 17 January 2023), Voice (November 2024) and many more languages. On 22 May 2024 the company announced a $300 million round at a $2 billion valuation.
Features and languages
The apps translate text, files, camera photos and dictation, and read translations aloud; paid plans add glossaries and formal or informal tone. For businesses DeepL promotes translation workflows connected to Google Drive, SharePoint and Adobe Experience Manager, plus terminology customization. On 24 June 2025 it added Vietnamese and Hebrew across all Translator versions, with Thai in early access on the API; DeepL said it added them in response to customer demand, especially from manufacturing.
Pricing and limits
According to the pricing page (shown in euros, VAT included, with 16% off for annual billing): the free version costs nothing, Individual is €7.49 per month, Team €24.99 per user per month, Business €49.99 per user per month and Enterprise is custom. The free version allows 50,000 characters per month; Individual 300,000; Team 1 million per user; Business unlimited under a fair use policy. Individual and Team offer a 30-day trial. In the iOS app, monthly plans range from $10.49 to $38.00 and annual plans from $104.99 to $384.99.
More analysis
What users report
App-store ratings are very high: 4.8/5 on the US App Store and 4.7/5 on Google Play. Trustpilot, however, shows only 2.4/5 from 790 reviews, where reviewers cite charges after trials, glossary limits dropping to 5 entries, and slow support. The sources measure different user groups, so they cannot be merged into a single figure.
Versus alternatives
Google Translate and Microsoft Translator are in the same category; this review does not compare translation quality across services since the sources reviewed contain no independent benchmark. DeepL fits best when you need glossaries, file translation and the data terms of its paid plans.

Cancellation & refunds
The sources reviewed do not state a refund policy. On Trustpilot, some reviewers report being charged after a trial or being refused refunds; these are reviewers' own accounts and are unverified.
Privacy
Per DeepL's privacy policy, the free version keeps submitted text and translations for a limited period and uses them to train and improve DeepL's neural networks and algorithms; no specific retention period is given. For paid (Pro) plans, texts are not used to improve the services and are not stored permanently, only kept until the translation is produced and then deleted. Saved translations, glossaries and Adaptive Translation data stay in the account until you delete them. The free version's terms prohibit translating personal data. Data is encrypted in transit, and documents are processed on infrastructure in the European Economic Area. DeepL SE is based in Cologne, Germany, the policy is written under the GDPR, and some third-party providers such as Stripe and Zendesk may involve transfers to the US. DeepL's business product page lists ISO 27001, SOC 2 Type II, GDPR, HIPAA and BSI C5 Type 2 compliance (self-reported).

Why this score
Paste text and translate, with web, mobile and desktop apps. App ratings are high (4.8 App Store, 4.7 Google Play). Some Trustpilot reviewers mention logouts and a Windows app bug.
Why this score
Text, file, image and speech translation; glossaries, tone, DeepL Write and an API. Most advanced features sit on paid plans.
Why this score
Individual costs €7.49 per month billed annually, and the free tier is capped at 50,000 characters. Trustpilot reviewers complain about limits, charges and refunds.
Why this score
Translation quality is its reputation, but the sources reviewed offer no independent benchmark. Trustpilot's review summary cites technical bugs and frequent app crashes, and some reviewers say quality changed after model updates.
Why this score
A help center exists, but many Trustpilot reviews describe slow or scripted replies, and Trustpilot notes DeepL has not replied to negative reviews.
Why this score
Paid plans do not train on texts, documents are processed in the EEA, and the policy follows the GDPR. Marked down because the free version trains on content with no stated retention period.
