AI Detector
See how your writing reads, with a likelihood score and the exact sentences that sound machine-written.
Hit Check text and your score shows up here.
How the checker works
It analyzes patterns like predictability, repetition and sentence rhythm, then estimates how likely the text is to read as AI-generated. Flagged sentences are highlighted so you know exactly where to look.
Scores are estimates
No detector is perfect. Short texts (under about 60 words) and very formulaic writing such as legal boilerplate can give unreliable results.

Questions, answered.
What does Wordflip actually do?
It rewrites AI-generated text so it reads like a person wrote it. It varies sentence length, swaps stock phrases for natural ones and matches the tone you pick, while keeping your meaning.
Will it change what I'm trying to say?
No. Wordflip changes how something is said, not what is said. Your facts, arguments and key terms stay put.
Which AI tools does it work with?
Any of them. Paste text from ChatGPT, Claude, Gemini, Copilot, DeepSeek or anything else, or your own rough draft.
Is my writing private?
Your text is used only to produce your result. We don't sell it, share it or use it to train models, and we don't keep a copy after your result is delivered.
Can I use it for school?
Wordflip is a writing tool, and how you use it is up to you. Many schools have rules about AI help, so check your school's policy and use it within those rules.
Can I cancel anytime?
Yes. Cancel from your dashboard in a couple of clicks and keep your plan until the end of the billing period.
