Does QuillBot work well in French?

The paraphraser, the grammar checker and the translator all list French among their languages. But the publisher does not release any per-language quality indicator, and the product was built on English: we have no basis to claim French is handled at the same level. Test it on your own texts, using the free tier, before any commitment.

Do my texts get used to train QuillBot's models?

By default, yes, since the privacy update of November 2025: storage of submitted text is switched on for all accounts, and that text can be used to train the models unless you turn it off manually in the settings. Only the Team plan is excluded by principle.

Who actually owns QuillBot?

QuillBot belongs to Learneo, formerly Course Hero, a US edtech group that also publishes CliffsNotes, Scribbr, Symbolab and LanguageTool. The acquisition dates from 2021; QuillBot has since run as a brand of the group, not an independent company.

How much does QuillBot cost for a team?

The individual Premium plan lists 8.33 €/month under an annual commitment. Beyond that, the Team plan applies a discount from five accounts, but its exact price isn't published: you have to go through the sales team, despite the real advantage of the training exclusion it offers.

What's the difference with Grammarly or ProWritingAid?

QuillBot bets on register-based rewriting and summarizing, while Grammarly focuses on continuous correction and ProWritingAid on detailed style reports. On data, the three differ: QuillBot trains by default outside the Team plan, Grammarly trains by default on individual accounts but not Business, and ProWritingAid states it never trains on texts, whatever the plan.

QuillBot: our review

QuillBot rewrites a sentence or paragraph in a chosen register (standard, fluent, formal, creative), corrects grammar and summarizes a long text. Bought by student-tools publisher Learneo, it stores and uses submitted text by default to train its models, except on its Team plan.

What we take away from it

What counts in its favor

Offers several rewriting registers (standard, fluent, formal, creative, academic) instead of a single forced rewrite, useful for adjusting the same paragraph for a client or an internal report.
The summarizer condenses a long document into a few sentences without switching to another tool.
The Team plan explicitly excludes submitted text from model training, a written and dated commitment.
A genuinely usable free tier for testing the rewriting register before buying, even with a length limit.

What counts against it

Since the privacy update of November 2025, retention of submitted text has been switched on by default for all accounts outside Team, including the free tier: you have to go turn it off yourself.
On the same accounts, that retained text is by default used to train the models that run the tool, on top of general service improvement.
French is advertised for the translator, the paraphraser and the grammar checker, but the publisher does not release any per-language quality measure: there is no way to know whether French is handled at the same level as English, on which the product was built. Test it on your own texts before paying.
Bought by Learneo (formerly Course Hero), an edtech group built on student summaries and plagiarism detection, whose long-term commercial interest is not guaranteed to align with professional business use.

Useful for quickly rewriting a text in English with several registers, provided you turn off storage and training yourself on an individual account. For regular professional use in French, or as soon as a sensitive contract is involved, the Team plan or another tool is the way to go.

What happens to your data

Is your data used to train their models?: Depends on the plan, or an option you can turn off
Subprocessors: The Trust Center mentions 'trusted service providers' worldwide, with no public named list. QuillBot states it has offices in the United States and India.
Retention: Since the update of November 8, 2025, retention of submitted text (web, extension, add-on) is switched on by default for all accounts. Two separate settings let you turn it off: keeping the text, and using it to train the models. No specific retention period is published. Team accounts are entirely exempt from training on their text.

QuillBot in detail

QuillBot rewrites a text in a chosen register — standard, more fluent, more formal, more creative — rather than imposing a single rewrite. It also corrects grammar and summarises a long document, in the same interface.

What it actually does

The typical use is to paste a paragraph, pick a register from about ten options (fluency, formality, length, academic), and compare the generated variants before settling on a version. The grammar checker runs in parallel on the same text, and the summariser condenses a report or an article into a few lines without switching tools. A sales team that needs to turn the same proposal into a shorter version for one client in a hurry and a more detailed one for another finds a direct use here.

What happens to the submitted text

This is the point that has shifted the most at QuillBot recently, and it's worth knowing before rolling the tool out widely. Since a privacy update dated 8 November 2025, retention of text entered via the web, the browser extension and the add-ons is enabled by default for all accounts, free and paid alike. This retained text can then be used to train the models that power QuillBot, unless the user goes and turns this setting off themselves — two separate switches exist: retaining the text, and using it for training. The one clear exception is the Team plan, whose texts are explicitly excluded from any training. A firm routing contracts through an unconfigured individual Premium account therefore lets that text feed the model by default. This is exactly the kind of setting we check during an AI audit and advisory engagement before recommending a tool to a client.

Why it interests us, and the question of French

The paraphraser, the grammar checker and the translator all list French among their languages. That's true, but unevenly so: independent tests run on French text find rewrites that sound less natural than in English, with occasional gender-agreement or register errors (informal "tu" versus formal "vous"). QuillBot remains a tool designed and optimised for English first, which limits its appeal for an SME that writes primarily in French — see our writing tools category to place this kind of tool against more complete French-language alternatives.

Where it falls short

Two further reservations. First, QuillBot belongs to Learneo, formerly Course Hero, an American group built on student summaries and plagiarism detection: professional use is not the publisher's historical core business, and product direction can shift with the group's priorities. Second, the team price isn't public: beyond the individual Premium plan at €8.33/month on an annual commitment, you have to contact the sales team to learn the price of the Team plan, despite the real advantage it brings on data.

Our recommendation

QuillBot is handy for quickly rewriting a text in English across several registers. For regular use with sensitive documents, or for use mostly in French, check the retention and training settings first, or go straight for the Team plan, which excludes them by default. The free tier remains fine for a one-off test — compare it against other free-tier AI tools before committing to an annual plan.

Who it's for, and who it isn't

Suited for

A freelancer or small team who rewrites texts in English and wants to compare several registers before choosing a final version
An organization that has subscribed to the Team plan, where training on submitted text is explicitly excluded
One-off use on a text that is already public or has no confidential character, where default storage isn't a risk

Not a fit

A firm that passes confidential client contracts or letters through a free or individual Premium account, without having turned off storage and training in the settings
A team that writes primarily in French: the advanced rewriting registers don't cover the language as finely as English
Management that wants a clear record of named sub-processors and hosting: QuillBot does not publish a public list of named sub-processors
