ABOUT SCRIBBR
The three-way split matters more than the headline score: "AI-refined" covers
the common real case of a human draft passed through a model for polish, which
a binary detector reports as a false positive. Scribbr states plainly that no
detector is fully accurate and publishes its own comparison research. Scribbr
and QuillBot are both Learneo properties, which is why Scribbr's detector page
recommends QuillBot's detector as the more advanced option.
OVERVIEW
- Who is it for?
- Students, applicants and academics who need a quick free check on a passage without creating an account.
- Problem
- Most detectors require sign-up and cap free usage, which is friction when the job is checking a single 1000-word essay section.
- Solution
- Scribbr's AI Detector runs unlimited free checks up to 1200 words per submission with no account, returns paragraph-level feedback, and separates human-written from AI-generated and AI-refined text. Scribbr's paid proofreading and plagiarism services sit alongside it.
- What makes it unique
- The three-way distinction between human-written, AI-generated and AI-refined output, plus genuinely unlimited free checks with no sign-up and no storage of submissions.
