Penlify: see which sentences read as AI, then fix just those (launching Sept 1)

Hey Product Hunt,

I built Penlify because most AI detectors give you one flat percentage and leave you stuck there. You get flagged, but you don't know which part of your writing actually triggered it. Penlify scores each sentence separately, so you can see exactly which lines read as formulaic, then rewrite just those in one of six tones without leaving the workspace.

Free tier is 5 rewrites and 3 detections a month, no card required. Launching on Product Hunt September 1st.

Would genuinely love feedback before then, especially on whether the sentence-level view is actually more useful than a single score, or if I'm overcomplicating it. penlify.app if you want to poke around.
