Check your textHow to read your AI detector score
The AI detector gives you a single number from 0 to 100. It is the estimated chance that AI wrote the text, not a yes or no. Here is what each band means.
Probably a person
Reads like human writing. We did not pick up the patterns a model tends to leave behind.
Hard to say
Some of it leans one way, some the other. Read it yourself before you draw a conclusion.
Probably AI
This has the marks of machine-written text. Read it closely before you conclude anything.

AI Detector vs Winston AI
Winston AI is an AI and plagiarism detector aimed at educators, writers and publishers. It runs on a freemium model: a free tier you can start without a credit card, then paid plans that unlock the full assessment, sentence-level analysis and plagiarism scanning. The useful parts need an account. This tool is free, needs no login, and is built for quick checks.

When Winston is worth it
If you check text constantly and want saved reports, plagiarism scanning and team features, a subscription tool like Winston can earn its keep. For an occasional read on a single piece, paying a monthly fee is hard to justify when a free detector does the core job.
Where your text goes
The check happens in memory on our own server. As soon as you have a score, your text is dropped. No logs, no database, no training set.
There is no account holding a history of your checks either.
