Hera vs Synthesia affiliate programs
Hera and Synthesia are AI video tools that both run affiliate programs. Hera lists 30% (capped at $100 per referral) through Cello; Synthesia lists 25% commission on all Starter and Creator plan payments through Rewardful. 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.
The payout structure is not stated for both programs. One of the two does not state a cookie window, so the attribution windows cannot be compared.
aifilliate publishes no ranking between Hera and Synthesia. 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.
