Grammarly vs WordHero affiliate programs
Grammarly and WordHero are AI writing tools that both run affiliate programs. Grammarly lists $0.20 per free signup + $20 per upgrade through Impact; WordHero lists 30%. One of the two does not state a cookie window, so the attribution windows cannot be compared. aifilliate records each program from a cited vendor source and does not rank the two.

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.
Grammarly pays one-time commission and WordHero pays hybrid, which typically matters more than the headline rate over a customer's lifetime. One of the two does not state a cookie window, so the attribution windows cannot be compared.
aifilliate publishes no ranking between Grammarly and WordHero. 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.
