Pricing FAQ
Yes. ChimpWrite Free humanizes up to 2,000 words per month (500 words per request, no signup required). The free tier includes Authentic Voice mode, the GPTZero scorecard, the diff view, and the Authenticity Score meter — enough to validate the workflow before buying credits.
You buy a one-time credit pack — $5 for 10,000 words, $10 for 25,000 words, or $25 for 75,000 words. There is no monthly or annual subscription. Credits never expire: buy what you need, keep the rest forever, and top up only when you run low. Every paid pack unlocks all P0 and P1 features, including Turnitin bypass and the full multi-detector scorecard.
No. ChimpWrite credits never expire. Buy a $10 pack today and use the remaining words in six months, a year, or longer — they stay on your account until you use them. This is the core difference from subscription tools like Undetectable AI or QuillBot Premium, which charge you every month even when you are not writing.
Verify your student status once with a .edu email address or an ISIC (International Student Identity Card). Every credit pack you buy then ships 50% more words at no extra cost: the $5 pack gives 15,000 words instead of 10,000, the $10 pack gives 37,500 instead of 25,000, and the $25 pack gives 112,500 instead of 75,000. Student pricing is restricted to personal and academic use.
Yes. Every paid pack — $5, $10, or $25 — unlocks the full P0 and P1 feature set: Turnitin-specific bypass, full multi-detector scorecard (GPTZero, Turnitin, Originality.ai, Grammarly, Copyleaks), all document presets, plagiarism check, browser extension, academic mode, voice profiles, and API access. The only difference between packs is the number of words. The $25 pack also includes a commercial use license.
Yes, with the $25 Heavy Pack (which includes a commercial use license) or by adding a one-time commercial license to a smaller pack. The Free tier and student-verified packs are restricted to personal and academic use. If you humanize content for paying clients, upgrade to the $25 pack or add the commercial license.
Undetectable AI charges $9.99 per month or $119.88 per year as a recurring subscription. ChimpWrite’s $10 credit pack covers 25,000 words (37,500 with student verification) as a one-time purchase that never expires. For a typical 25,000-word study-abroad application season, ChimpWrite is 83% cheaper than six months of Undetectable AI — a $49.94 saving — and 87% cheaper for verified students.
Regional pricing for India, Nigeria, Vietnam, Brazil, and MENA is on the roadmap and will launch after the global credit-pack rollout. Until then, students in those regions can use the Free tier or buy credit packs at the listed USD price.
