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.
