About Grammarly
Grammarly is the biggest consumer name in AI writing assistance, used by students, professionals, and non-native English writers. The free browser extension delivers instant, visible value, which is why the free-to-paid funnel works: Grammarly's own program page claims 20 to 30% conversion rates, unusually high for a consumer SaaS offer.
The economics are pure CPA, confirmed in Grammarly's support docs: $0.20 for every free account signup with no payment info required, and $20 for each Premium upgrade, plus an activation bonus and raised payout tiers for top content affiliates. The 90-day cookie is generous for a B2C product. The program runs on Impact.
The weaknesses are structural. Nothing recurs, so you rebuild revenue every month, and the $0.20 free-signup payout only matters at serious volume. Payments come by check (US only), bank wire, or direct deposit in USD; there is no PayPal, which non-US affiliates should factor into the math before committing traffic.
