What matches, what differs
Differences
- Payout structure differs: recurring against one-time.
- Grammarly lists the longer referral cookie: 90 days against 60.
In common
- Both are AI writing tools.
What these terms mean in practice
Attribution splits between day 60 and day 90. A referral who clicks today and subscribes on day 75 is still credited by Grammarly, but no longer by aiWriter.ai.
A customer who stays subscribed for two years pays out on every qualifying renewal with aiWriter.ai, and once with Grammarly. Which produces more depends on plan price and retention, neither of which appears in published terms.
Which record fits which promoter
- aiWriter.ai: suits audiences that convert quickly; its 60-day window is shorter, so timing matters more.
- Grammarly: suits traffic that deliberates before buying — the 90-day window still credits slow conversions.
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.
- Grammarly does not publish a payout threshold.
- aiWriter.ai does not publish the platform running the program.
How to read these two records
These payouts do not share a basis — one is quoted as a percentage, the other as a flat amount per conversion. A percentage of an unknown plan price and a fixed bounty are not the same unit, so aifilliate does not rank them.
aiWriter.ai pays recurring commission and Grammarly pays one-time, which typically matters more than the headline rate over a customer's lifetime. Grammarly lists the longer referral cookie: 90 days against 60.
aifilliate publishes no ranking between aiWriter.ai and Grammarly. 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.
