AI SaaS Starter Kit — Build a GPT App That Sells
The AI gold rush rewards speed. LaunchKit's AI module gives you streaming chat endpoints, token metering, rate limits and upgrade paywalls — the difference between a demo and a business.
Streaming UX users expect
Server-sent streaming with graceful fallbacks, optimistic UI, markdown rendering and abort handling. Your app feels like ChatGPT on day one.
Costs under control
Per-user token metering and tiered rate limits are wired to the billing module, so free users can't bankrupt you and paid users get instant upgrades.
