What matches, what differs
Differences
- GPTZero lists the longer referral cookie: 60 days against 45.
In common
- Both are AI writing tools.
- Both pay recurring commission.
- Both run on Rewardful, so one dashboard covers them.
What these terms mean in practice
Attribution splits between day 45 and day 60. A referral who clicks today and subscribes on day 53 is still credited by GPTZero, but no longer by WriteHuman.
Which record fits which promoter
- GPTZero: suits traffic that deliberates before buying — the 60-day window still credits slow conversions.
- WriteHuman: suits audiences that convert quickly; its 45-day window is shorter, so timing matters more.
What is not published
Anything below has to be confirmed with the vendor before either offer can be modelled. aifilliate records it as unknown rather than estimating it.
- WriteHuman does not publish a payout threshold.
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.
Both pay recurring commission. GPTZero lists the longer referral cookie: 60 days against 45.
aifilliate publishes no ranking between GPTZero and WriteHuman. 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.
