Unlimited free AI detector plus a humanizer and rewriter that make drafts read like you wrote them
Check as many drafts as you want with no daily limit and no signup. Results arrive as sentence-level highlights with a reason for each flag, so the score becomes something you can act on.
Nine modes spanning Standard, Academic, Blog, Formal and Simple plus premium options reshape sentence length and strip stock connectors while preserving the original meaning.
Adjustable rewrite tones for lighter editing and a grammar pass for polish, both living in the same account as detection so the workflow stays in one place.
Humanize, detect and refine text inside Google Docs, email, LMS and CMS editors through the browser menu instead of juggling tabs.

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.
