Common questions
Is the humanizer for evading AI-detection systems?+
No. The humanizer is a writing-voice tool. It strips mechanical AI tells (em-dashes, hedging openers, recycled connectors) so the rewrite reads like natural student prose. The voice fingerprint anchors that rewrite to your own past work, so the result is your authentic voice on the page. We don't market, document, or build around evading detection.
What's the difference between the humanizer and the voice fingerprint?+
The humanizer is the rewriter: it takes prose in and produces a more natural version. The voice fingerprint is a small profile of *your* writing, built from two or three pieces you've already submitted. With a fingerprint enabled, the humanizer's output stays anchored to your own sentence shape, vocabulary, and quirks, not a generic 'student tone'.
What happens to my uploaded files?+
Files live in your private Supabase storage with row-level security. We don't train on your content. Humanizer telemetry captures latencies and error codes, not payloads.
Can I cancel anytime?+
Yes. Plans cancel at the period end; you keep access until then. Free is free forever.
Is annual billing cheaper?+
Yes — annual plans bill once a year and work out cheaper than month-to-month: Plus is $72/year (save $24) and Pro is $160/year (save $80). Toggle to Annual above to see it. You still keep access through the period if you cancel.
Do you have a student discount?+
The Plus tier is already priced for students at $8/mo (or $72/yr). If your school has a site license, email us.
