Penlify
See which sentences read as AI, then rewrite just those
Penlify shows which sentences in your writing read as AI-generated, sentence by sentence instead of one vague score, then rewrites just those while keeping your meaning and tone. Built for students, freelancers, and anyone whose own writing keeps getting falsely flagged. Free plan included, no card required.
Hey Product Hunt! I built Penlify after watching AI detectors flag genuinely human writing as machine-generated: formal emails, non-native English, heavily edited drafts, all treated the same as raw ChatGPT output.
Most humanizers try to lower a detector score by swapping words, which usually damages the meaning. Penlify does two things instead: it shows which specific sentences are actually reading as AI-like instead of one vague percentage, and lets you rewrite just those sentences in a tone you choose, keeping your point intact.
Free plan is 5 rewrites and 3 detections a month, no card required. Would love feedback, especially from anyone who's been falsely flagged before.
