European paraphrasing tools: 6 EU rewriters checked, down to who keeps your text

Le Chat, renamed Vibe by Mistral in 2026, is the assistant of Mistral AI, a French company (SAS) based in Paris that trains its own language models. It has no paraphrasing modes. You paste a paragraph and say what you want: "half as long", "neutral tone for a client", "plain English for a non-native reader", "keep every figure". That free-form instruction is why it ranks first: no other European tool here lets you steer the output this precisely.

The setting to change before you paste anything. On individual accounts, Free and Pro alike, Mistral says you are "not opted out by default": your chats can be used to train its models. Enterprise accounts are opted out by default. On the web, turn off "Allow your interactions to be used to train our models". On mobile, turn off "Enable data sharing". Do it once, before your first client document.

Pricing. The free plan has "limited messages and web searches". Pro is $14.99 a month excluding tax, Team is $24.99 per user per month, and Enterprise is quoted. The pricing page has a currency switch, so check the amount in your own currency at checkout.

Where it falls short. Public review sites give Mistral a low average, and the most common complaint is how hard it is to cancel a subscription. Positive reviews praise the answers and the European hosting. And without ready-made modes, quality depends on your prompt.

Tip: keep one reusable instruction in a note ("rewrite without changing the meaning, add nothing, sentences under 20 words") and paste it before each text. Your rewrites stay consistent from one document to the next.

Best for teams and freelancers who rewrite varied content and want full control. Not for anyone who wants a one-click button. For a company rollout, see our Mistral agency.

DeepL Write comes from DeepL SE, the Cologne company behind the DeepL translator. It rewrites in English, German, French, Italian, Portuguese and Spanish. Non-native writers like it for a simple reason: it shows a better way to say what you meant, without changing the meaning. Developers on forums say they use it to improve their German, and call it one of the most useful style tools they have.

The data point. On the Pro plans, DeepL says your content is never used to train its models. That is the clearest written commitment in this ranking. The free version limits how many texts you can improve, without publishing the exact number.

Pricing. Write Pro is an add-on at €6.99 per user per month, billed yearly. DeepL Pro plans start at €7.49 a month (Individual), then €24.99 (Team) and €49.99 (Business), billed yearly and including VAT on the European price page. US prices may differ, so check the page for your region.

Where it falls short. The free version is capped without a published number, and Write Pro is sold as an add-on to a DeepL subscription rather than as a standalone plan.

Best for professionals who want clean, faithful rewrites and a vendor bound by EU law. Not for anyone who needs a French company specifically. Leaving DeepL? See the DeepL alternatives.

MerciApp is a venture-backed start-up from Paris. Its rewriting feature is called Transform: select a sentence or a paragraph in your browser and make it clearer, shorter or change its tone, through an extension. It checks English, French, Spanish, German and Portuguese.

Hosting. The pricing page states hosting exclusively in France. That's the most direct hosting statement in this ranking after Scribens. We couldn't load the legal notice, though, so ask for the company registration number if procurement needs it.

Pricing, excluding VAT. The free plan checks 600 words a day and gives 3 Transform rewrites a day. Assist costs €24 a month billed monthly, or €144 a year billed yearly (€12 a month): the yearly plan halves the bill. The Assist trial lasts 30 days, no card needed. Enterprise is handled by a sales expert.

Where it falls short. Public reviews talk about the grammar checker (false positives, a slow support reply, a billing issue), almost never about Transform. The best-known review platform has also suspended MerciApp's rating, so read recent reviews before paying for a year.

Tip: the three free rewrites a day are enough to judge the output on your real emails. Start the 30-day trial only when you have a big batch to rewrite.

Best for office teams who write lots of email and want French hosting. Not for deep rewrites of long texts.

Mammouth is published by Mammouth AI SAS, registered in Paris. It doesn't train its own model: it gives you the models of several vendors (Mistral, Claude, GPT, Gemini and more) in one interface. For rewriting, that means you paste a sentence, ask for a tone, then rerun the same prompt on another model and keep the best version.

Data. Mammouth states that your content is never used to train models and that its providers don't retain prompts sent through it. Its privacy policy says data is processed and stored in the European Economic Area. Your request still goes to the provider of the model you pick, often a US one: for sensitive text, choose a Mistral model in the list.

Price. No free plan: Starter is $12 a month excluding VAT, Standard $24, Expert $72.

Best for heavy rewriters who want to compare models without paying for three subscriptions. Not for students looking for a free button.

Reverso is the name most people know for rephrasing in French, English, Spanish or Italian. REVERSO SAS is listed in the French company register in Neuilly-sur-Seine. Its rephraser sits next to the translator, the context dictionary and the grammar checker.

Price. Premium is €6.49 a month billed yearly (€77.88 at once) or €9.99 month to month, with unlimited AI rephrasing. Students and teachers get 75% off, €19.47 a year. The pricing page doesn't say whether VAT is included, so check the total before paying.

Limit. The free version is heavy on ads, and users complain about being pushed to subscribe. The pricing page says nothing about where your text is hosted.

Best for students and everyday writers. Not for companies that must prove where their text goes.

Scribens publishes everything a buyer wants in its legal notice: SCRIBENS SARL, Montpellier, France, trade register number 841 985 633, hosted by OVHcloud in Roubaix. A French company on a French host, verifiable in two minutes. No other tool in this ranking is that explicit.

Paraphrasing. The free plan includes limited rewriting (the cap isn't shown). Premium makes it unlimited, with 20 different tones. The checker covers more than 40 languages, but the interface and rewriting are built French-first.

Pricing. Scribens doesn't show the Premium amount on its public pages: it appears at checkout, depending on the duration you choose.

Where it falls short. The free version runs on ads, and users point out that the cookie banner has no one-click "reject all" button.

Best for students and individuals who write in French and want to play with tone. Not for anyone who wants to see the price before signing up. See also our European grammar checkers.

LanguageTool is often called the European alternative to US grammar tools, and its publisher, LanguageTooler GmbH, is based in Hamburg. The brand now belongs to Learneo, the US group that also owns QuillBot. So the product has European roots, but the group that controls it is American: we apply the same rule as for QuillBot, so it stays outside the European ranking.

Paraphrasing. The free plan gives 3 rephrasings a day, on top of the grammar checker. Premium unlocks more, but the price only appears at checkout, depending on your country and billing period. We don't quote a figure we couldn't read on an official page.

Best for writers who switch between several languages and already use LanguageTool for grammar. Not for anyone who needs a vendor outside US control. Thinking of leaving? See the LanguageTool alternatives.

QuillBot is the tool most people mean when they search for a paraphrasing tool, which is why it's here as the benchmark. It belongs to Learneo, a US group, so it doesn't qualify as a European vendor.

The free plan rewrites up to 100 words at a time. Premium is $8.33 a month billed yearly. Annual renewals are a recurring complaint among users: set a reminder before the renewal date if you only need it for a semester.

Best for students writing in English who don't need an EU vendor. Not for teams with a European-vendor policy. Read our full QuillBot review.

Ludwig is the first result for "European paraphrasing tool", and for good reason: its publisher, LUDWIG SRLS in Palermo, Italy, coordinates EUPHRASER, an EU-funded project to build "an AI powered Paraphraser based in Europe". The goal is to generate several alternative phrasings of a sentence that differ in vocabulary and structure while keeping its meaning. Ludwig is best known as a sentence search engine for English: you check how real, reliable sources phrase an idea.

Why it isn't ranked. Its site blocked us from reading its pricing page, and we don't publish a price we haven't read from the vendor. It stays here because it is the clearest example of a European-built English paraphraser.

Best for non-native writers polishing English. Not for rewriting in French or Spanish.
