Will it change what I said?
No. Every claim in the output has to trace to a sentence in your draft, and a sentence that cannot be preserved safely is kept and flagged rather than smoothed over. Then the rewrite is audited against the draft — numbers, dates, names, quotes, links — and the warnings are on screen before you copy anything. That constraint sits in front of everything else the rewriter is told.
Can I put client email through it?
Your drafts are not stored. The text goes to the model, the rewrite comes back, and the draft is gone: there is no draft history in this product, so there is none to leak and none to hand over. The rewrite itself is kept encrypted for thirty days so that asking twice gives you the same answer, and it deletes itself. Whether that clears your own client agreement is a call only you can make, and it is worth making before you paste something covered by one.
Does it sound like me?
It can. Paste a few things you have written and it measures your rhythm — how long your sentences run, how much that varies, how often you run short — then shapes rewrites to those numbers rather than to the default voice. That measuring happens in your browser and needs no account. What it does not do yet is pick up your vocabulary, so out of the box it sounds like you in shape and like one considered voice in word choice.
Will this beat an AI detector?
That is not the promise, and anyone making it is guessing. Detectors change weekly and any text can be edited past one, including by this. What you get is prose that stopped carrying the marks — which is the part an actual reader notices, and the part you were worried about anyway.
