What matches, what differs
Differences

In common
- Both are AI writing tools.
What these terms mean in practice

Which record fits which promoter
- QuillBot: suits audiences that convert quickly; its 30-day window is shorter, so timing matters more.
- Undetectable AI: suits traffic that deliberates before buying — the 60-day window still credits slow conversions.

How to read these two records
Both rates are stated as percentages of customer payments, so the figures share a basis. They may still cover different plans, billing terms, and eligibility rules.
The payout structure is not stated for both programs. Undetectable AI lists the longer referral cookie: 60 days against 30.
aifilliate publishes no ranking between QuillBot and Undetectable AI. Which program earns more depends on plan price, conversion rate, retention, and refund reversals in your own audience — none of which appear in published affiliate terms. Confirm eligibility, paid-search and trademark rules, and payout timing with each vendor before promoting either.
