A collection of tools for revising existing writing
Quillbot is particularly useful when you already have text to improve. Its Paraphraser offers different ways to express a passage, while the Grammar Checker addresses errors and the Summarizer reduces longer material. Citation generation, plagiarism checks and other AI tools sit alongside those core editing features. Projects and Flow provide a place to organise writing rather than treating each passage as a separate task.
The free plan includes Standard and Fluency paraphrasing modes and shorter text allowances. Premium expands rewriting controls with more modes, custom modes, history and mode comparison. A synonym control gives another way to change how extensively wording is revised. These options help explore alternative phrasing, but the writer still needs to check that a rewrite preserves the intended meaning and factual detail.
The tools have different language coverage and different limits. The live plan comparison lists 23 paraphrasing languages, more than 40 translation languages and grammar correction in six. Premium plagiarism scanning has a monthly word allowance rather than unlimited scans. Browser extensions, desktop apps, a Word add-in and mobile tools extend access, although the exact features can differ between platforms. Team plans add user administration and central billing.
Best for
- Writers exploring alternative phrasing
- Students revising drafts and references
- People summarising longer text
Limitations
Paraphrasing can alter meaning and does not remove citation obligations. AI detection is not proof of authorship. Tool limits, language support and platform features differ, and Premium plagiarism scans have a monthly allowance.

Yes. Free access includes limited paraphrasing, basic grammar tools and summaries. The live plan comparison lists a 125-word paraphrasing limit and Standard and Fluency modes.
Is Quillbot Premium unlimited?
Premium expands paraphrasing and modes, but not every tool is unlimited. Summaries have their own allowance and plagiarism checks include 25,000 words per month.
What languages does Quillbot support?
Coverage depends on the tool: the live comparison lists 23 paraphrasing languages, more than 40 translation languages and grammar correction in six.
