What Reverso actually does
Reverso is a French language-tools service headquartered in Neuilly-sur-Seine, just outside Paris, that has offered free online translation since the late 1990s and has since grown into a much broader toolkit for anyone reading, writing or learning a foreign language. Rather than being just a translator, it pairs machine translation with a bilingual context dictionary, verb conjugation tables and an AI grammar and rephrasing tool across dozens of languages.
The core product
The base translator handles plain text across more than 25 languages, and it's built on neural machine translation, the same general approach used by most modern translation engines.
What sets Reverso apart is what sits around that translator:
- A context dictionary that shows real bilingual example sentences pulled from previously translated documents and film or TV subtitles, so you can see how a word or phrase is actually used rather than just getting a single dictionary definition
- Verb conjugation tables covering ten languages
- Synonym lookups
- An integrated grammar and spell checker
It's available as a web app, a Mac and Windows desktop app that can translate text in any application with one click, iOS and Android apps, and browser extensions for Chrome, Edge and Firefox — and a document translator that tries to preserve the layout of Word, PDF, PowerPoint and Excel files. No account is required for everyday lookups or short translations, which makes it easy to use for a quick check without any commitment.
What's new or notable
The most useful addition on top of plain translation is Reverso's AI-based Correct and Rephrase tool, which checks grammar and offers alternative phrasings in English plus three other languages — genuinely useful for someone drafting an email or message in a language they're still learning, not just translating word-for-word. On the free plan this tool is available but limited; unlocking unlimited use requires Reverso Premium.
Premium also:
- Raises the amount of text you can translate in a single request, up to 8,000 characters at once
- Increases the yearly allowance for document translation to 50,000 words
- Syncs saved vocabulary and flashcards across devices without the caps the free plan applies to saved terms
Who should use Reverso
Great fit if…
- You need occasional translations, conjugation checks, or dictionary lookups. All of these are free, require no account, and cover the vast majority of casual language needs.
- You're learning a language and want to see real usage, not just definitions. The context dictionary's bilingual example sentences, pulled from real translated text and subtitles, show how words are actually used in practice.
- You write in a foreign language and want grammar help beyond translation. The integrated grammar checker and AI-based Correct and Rephrase tool go further than a plain translator.
- You want one tool across your phone, desktop and browser. Reverso's web app, desktop app, mobile apps and browser extensions all work together rather than being separate products.
Skip it if…
- You regularly translate long texts in a single request. The free plan caps how much text you can translate at once; Premium is needed to translate up to 8,000 characters in one go.
- You lean heavily on AI rephrasing or correction. Unlimited use of the Correct and Rephrase tool is Premium-only, so frequent users of that feature will hit free-tier limits.
- You translate a lot of full documents. Free document translation is restricted, while Premium's 50,000-word yearly allowance is needed for regular document work.
- You want to save large amounts of vocabulary across devices. Saved terms and flashcards are capped on the free plan; Premium is required for unlimited, synced vocabulary.
Pricing in detail
Reverso's core tools are free with no account required; Reverso Premium unlocks higher limits and unifies every Reverso product under a single subscription.
| Plan | Price | What's included |
|---|---|---|
| Free | €0 | Text translation across 25+ languages, context dictionary with bilingual example sentences, verb conjugation in 10 languages, synonym lookups, integrated grammar and spell checker, and limited document translation and AI rephrasing, with per-request length caps. |
| Premium | €9.99/month billed monthly, or €6.49/month billed annually (€77.88/year) | Translation of up to 8,000 characters per request, unlimited AI-based Correct and Rephrase in English plus three other languages, a 50,000-word yearly document-translation allowance, and unlimited saved vocabulary and flashcards synced across devices. |
Where it falls short
- Free translations are capped in length per request. Anyone regularly translating longer passages will need Premium's 8,000-character-per-request limit rather than working around the free tier's shorter cap.
- Free document translation is restricted. Where Premium offers a 50,000-word yearly allowance for translating whole documents, the free tier limits this significantly, making it impractical for anyone translating documents on a regular basis.
- AI rephrasing is capped without Premium. The free version of Correct and Rephrase is more limited than the unlimited access Premium provides, which matters most for people actively drafting in a non-native language.
- Premium is an all-or-nothing subscription. Rather than paying only for the one feature you want more of — say, just document translation, or just unlimited rephrasing — Premium unlocks every Reverso product at once, which is good value if you use several of them but less so if you only need one.
Privacy & data
Reverso is a French company headquartered in Neuilly-sur-Seine, near Paris, which means it operates under GDPR as an EU-based service, giving users baseline rights over how their data is collected and processed. Beyond that jurisdictional protection, Reverso's public pages checked for this review did not spell out in detail how long submitted text is retained or whether it contributes to training Reverso's translation or AI rephrasing models.
Given that the context dictionary itself is built from a large corpus of previously translated documents and subtitles, anyone translating confidential or sensitive material regularly should check Reverso's current privacy policy directly rather than assume specifics that weren't independently verifiable here.
How we checked this
This review is based on Reverso's own website (reverso.net), checked on 4 September 2026, describing free-tier and Premium features, along with Reverso's document-translation pricing pages for current Premium subscription rates. We did not conduct hands-on translation-quality testing across Reverso's supported languages; feature descriptions and limits reflect what Reverso publishes about its own free and Premium tiers at the time of checking, and specific limits may be adjusted by the company over time.
