Free AI content detector that flags machine-written text and helps you rewrite it
The checker returns an overall AI probability plus a per-sentence breakdown, so you can see exactly which lines read as machine-written instead of guessing from a single number.
Flagged sentences come with an explanation of what triggered the flag and one-click rewrite suggestions that reduce tell-tale AI patterns while keeping your meaning.
Optional plagiarism, grammar and fact-check modules can be layered onto the same text, turning a single submission into a broader originality and quality review.
Paste text directly or upload files, and scan multiple documents in one pass when you are reviewing a stack of papers or drafts.

Academic proofreading, plagiarism checking and AI-powered writing tools in one place
A vetted academic editor reviews your paper within hours and returns tracked changes, comments and an explanation letter.
Scans your document against a large web and publication database to surface potentially unoriginal passages before submission.
Flags text likely generated by large language models and offers a rewriting mode aimed at making AI-assisted drafts sound more natural.
Creates and verifies references in APA, MLA, Chicago, AMA, IEEE and ACS styles from a URL, DOI or title search.
