Common questions
Yes. 5 rewrites free when you make an account, no card needed. Sign in with Google or an email address and start straight away. After that, pick a plan if you want to keep going.
Card or M-Pesa, both handled by Paystack. Visa and Mastercard work fine. Your card details go to Paystack, never to us, and we do not store them.
Nothing gets charged again. There is no subscription to cancel. Your account drops back to the free tier and you buy another pass whenever you next need one.
Yes. Cards work from anywhere. Outside Kenya we show prices in USD as a guide, but the charge itself goes through in Kenyan Shillings. You see the exact KES amount before you pay and your bank handles the conversion at its own rate. M-Pesa is for Kenyan users.
No, because access starts the second you pay. If something on our side stops you using the tool, message support. We will fix it or add the lost days back to your plan.
Most people need this for one essay or one project, not every month. A subscription keeps taking money long after you stopped using it. Buy a day, a week or a month, and it just ends.
No. Nothing here connects to your university, your LMS or Turnitin. A detector only ever sees the text you submit to it. Worth knowing either way: a detector score is not proof of who wrote something, and your institution's policy decides what is allowed, not the number.
AI detection is a probability, not a verdict. Two things to try. Switch to Drift, which varies the style most. Or run a 2-Pass rewrite, Simplify then Elevate, which restructures the text twice. Check the live detector score in the app before you hand anything in.
QuillBot mostly swaps words for synonyms. Detectors are trained on exactly that, so the score barely moves. This runs your text through models tuned to change sentence rhythm and structure, gives you three versions, and scores each one with two AI detectors while you watch. There is also a meaning check you can run in ChatGPT or Claude to confirm your argument survived.
