Side-by-Side Comparison
Our Verdict
**The Bottom Line:** Copy.ai has the higher headline rate — 45% vs. Synthesia’s 25% — and the same 12-month recurring window and cookie duration. If you compare purely on percentage, Copy.ai pays more per dollar of subscription revenue. However, Synthesia’s enterprise audience and Fortune 100 adoption typically mean much larger average contract values, so a single Synthesia referral could outweigh multiple Copy.ai signups in raw dollars. If you drive high-volume, SMB-friendly traffic, Copy.ai is the smarter bet. If you can reach corporate buyers, Synthesia likely pays more in total lifetime commissions. There is no universal winner — the better program is the one matched to your audience.
