Questions
What does it actually change?
It strips markdown (the stray asterisks and hash signs), removes hidden characters such as zero-width spaces and non-breaking spaces, swaps American spellings for British ones and, if you like, changes em dashes and quote marks to British style. Every change is highlighted, and you can tap any of them to undo it.
Does it rewrite the AI clichés for me?
No, on purpose. Swapping "delve" for a synonym just produces a different cliché. It picks out the phrases that make text read as AI and says why, then you rewrite them in the box on the left and watch the count go down.
Does it remove AI watermarks?
No, and be wary of anything that claims it can. Text watermarks are not hidden characters. They are statistical patterns in which words a model chooses, so tidying formatting doesn't touch them. This tool is about making a draft read like you wrote it, not about hiding where it came from. More on how text watermarking works.
Is my text uploaded anywhere?
No. Everything runs in your browser. If you tick "Remember on this device", your writing sample is stored in your browser only.
Why are some words underlined in blue rather than changed?
Some spellings depend on meaning. "Draft" is right in British English for a document but not for a breeze, and "program" is right for software but not for the theatre. Those get flagged for you to decide, along with American words such as "vacation" or "sidewalk".
