Launching Penlify on Product Hunt September 1st. Built it after getting frustrated with AI detectors that hand you one confusing percentage and stop there you're stuck guessing which part of your draft actually triggered it.
Penlify checks sentence by sentence instead, then lets you rewrite just the flagged lines in the same workspace no bouncing between a checker and a separate editor. Free tier is 5 rewrites and 3 detections a month, no card required.
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.
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.
