ChatPRD, an AI co-pilot for product managers, has scaled to 20,000 users in just a few months using the Vercel stack. Founder Claire Vo built the platform from scratch and focused on developing its core functionalities with the help of Vercel's infrastructure and logging tools. The AI SDK provided by Vercel simplified the implementation of streaming responses and generative UI components, significantly improving user experience and accelerating ChatPRD's time to market.
