Ehsan's Growth Analysis
Grammarly's browser extension strategy was a decade ahead of its time. By inserting themselves into every text field on the internet, they created the most persistent distribution mechanism in SaaS. Users do not "open" Grammarly — it is always there, always visible, always reminding you it exists. That constant presence drives a conversion rate from free to paid that most freemium companies would envy. The 30M DAU number is impressive, but the real metric is usage frequency: Grammarly users interact with the product 20-30+ times per day. No other SaaS product has that kind of engagement. That frequency creates habit formation that makes churn nearly impossible. The extension is not a distribution channel — it is the product.
