- Expand
A useful synonym slider lets you control how much the text is altered. For example, you can keep it close to the original or aim for maximum rewording.
In tests, QuillBot handled most general and academic content well, making smart replacements that improved tone or variety without losing meaning.
2. Grammar Checker
Comparable to Grammarly’s free version, the QuillBot grammar checker reliably catches common issues with punctuation, spelling, and sentence structure. It isn’t quite as nuanced when it comes to tone or readability scores, but it’s more than enough for everyday writing.
3. Summarizer
Paste a long article and get a short summary or bullet-point version. Ideal for:
- Research notes
- Blog outlines
- Email digests
It’s especially useful for students trying to digest dense academic material or bloggers wanting a quick recap for social media.
