What is Quillbot?
Quillbot supports people writing or revising texts with paraphrasing and grammar correction. It also allows users to summarize documents, translate text, and create bibliographic references for their writing.
According to its documentation, Quillbot lets you:
- paraphrase text in several styles
- correct grammar and spelling
- summarize a document
- translate text
- create bibliographic references
We file it under Grammar and paraphrasing, the category of tools to fix and rephrase text, and it also overlaps with aI translation and aI summarisers. The category lists 11 verified tools on this site.
The publisher is Learneo, Inc.. The service launched in 2017, which gives it some track record.
Who is it for?
It is mostly useful to these profiles: content writers, students, teachers, and translators. The need it covers is simple to state: fix and rephrase text.
Quillbot is a good candidate if:
- you want to try before paying
- you also work from your phone
The best test is a concrete case from your daily work: if the tool does not beat your current method within a week, move on to an alternative.
How much does Quillbot cost?
Pricing model: freemium (limited free use, then paid). A free plan is offered, usually limited in volume or features.
The first paid plan costs €8.33 per month (Premium, monthly equivalent with annual billing; currency displayed at the time of recording), according to the pricing page, checked on October 24, 2026.
Per month, that is close to the category median ($8 per month, based on tools with a published price).
To estimate what the same work would cost done directly with an AI model, use our API price calculator. Prices change often: always check the official site before subscribing.
Data and privacy
The publisher does not clearly state where data is hosted. Assume your content may leave your region.
For professional use, check that a data processing agreement (DPA) is offered, and do not send customers' personal data or confidential documents without one.
Exporting your content: DOCX. Being able to get your data back makes switching tools easier later.
Three habits apply to every AI tool:
- turn off the use of your content for training if the option exists
- use a work account separate from your personal account
- review everything the tool produces before publishing or sending it
