Async vs Sembly AI affiliate programs
Async and Sembly AI are AI voice tools that both run affiliate programs. Async lists 25% recurring commission for every paid subscription; Sembly AI lists up to 25% through FirstPromoter. 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
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. One of the two does not state a cookie window, so the attribution windows cannot be compared.
aifilliate publishes no ranking between Async and Sembly 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.
