- Synthesia lists the longer referral cookie: 60 days against 30.
What these terms mean in practice
Attribution splits between day 30 and day 60. A referral who clicks today and subscribes on day 45 is still credited by Synthesia, but no longer by Speechify.
A customer who stays subscribed for two years pays out on every qualifying renewal with Synthesia, and once with Speechify. Which produces more depends on plan price and retention, neither of which appears in published terms.
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.
- Neither vendor publishes a payout threshold or the platform running the program.
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.
Speechify pays one-time commission and Synthesia pays recurring, which typically matters more than the headline rate over a customer's lifetime. Synthesia lists the longer referral cookie: 60 days against 30.
aifilliate publishes no ranking between Speechify 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.
