How to Monetize a Free AI App
Generate Revenue Without Adding Paywalls
You built a free AI app because you wanted maximum reach. Now you need to figure out how to make money without destroying what makes it great.
Adding a paywall would kill your growth. Banner ads look terrible in chat interfaces. What else is there?
Actually, quite a lot. Here's what's working for free AI apps in 2025.
Why Traditional Monetization Fails for Free AI Apps
- Paywalls: Kill growth. 95%+ of users leave. You lose the network effects that made your app grow.
- Banner ads: Look terrible in conversational interfaces. Users hate them. Engagement drops.
- Interstitial ads: Interrupt the flow. Destroy the conversational experience.
- Freemium conversions: At 2-5% conversion, you're subsidizing 95%+ of users with zero revenue.
