Pre-calculated savings vs subscription competitors
ChimpWrite credits are one-time and never expire. Competitor prices are recurring subscriptions — you keep paying even in months you don’t write. See the full Undetectable AI review or browse Undetectable AI alternatives.

Pricing FAQ
Yes. You can try 150 words per request instantly with no signup, and a free account unlocks 1,500 words every month (300 words per request). The free tier includes all three humanization levels, the authenticity estimate on every run, the diff view, and humanization history — enough to validate the workflow before buying credits.
You buy a one-time credit pack — $5 for 5,000 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 switches you to the premium engine — our most natural rewrites — and raises the per-request and daily caps.
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 7,500 words instead of 5,000, 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.
Every paid pack — $5, $10, or $25 — unlocks the premium engine, all document presets, the authenticity estimate, the diff view, and history. Packs differ in words and velocity caps (words per request and requests per day), and the $25 pack adds a commercial use license. Independent third-party detector verification is on the roadmap as a paid add-on and is clearly labeled as coming soon until it ships.
Yes, with the $25 Heavy Pack, which includes a commercial use license. The Free tier, smaller packs, and student-verified packs are restricted to personal and academic use.
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.
