The primary value of AI coding assistants is not just writing code faster, but rapidly prototyping ideas to determine their viability. This allows teams to quickly decide whether a feature is worth pursuing, saving significant time and resources on dead-end explorations.

AI tools democratize prototyping, but their true power is in rapidly exploring multiple ideas (divergence) and then testing and refining them (convergence). This dramatically accelerates the creative and validation process before significant engineering resources are committed.

The goal isn't to build one perfect prototype quickly. The real strategic advantage of AI tools is the ability to generate three or four distinct variations of a feature in a short time. This allows teams to explore a wider solution space and make better decisions after hands-on testing.

Instead of debating hypothetical ideas, tools like Vercel's v0 let anyone build and present functional prototypes. This shifts the conversation from prioritizing abstract concepts to evaluating tangible results, allowing teams to defend the merits of an actual working idea.

In AI, low prototyping costs and customer uncertainty make the traditional research-first PM model obsolete. The new approach is to build a prototype quickly, show it to customers to discover possibilities, and then iterate based on their reactions, effectively building the solution before the problem is fully defined.

Stripe built "Protodash," an internal tool that allows designers, PMs, and engineers to quickly create high-fidelity AI prototypes that mirror the real product. This removes the bottleneck of needing engineering for early exploration and empowers proactive, cross-functional ideation.

Companies are using AI tools like Perplexity Computer to build functional MVPs almost instantly. This cultural shift allows teams to interact with a working version of an idea to gauge its value before investing significant engineering resources, replacing the traditional text-based planning phase.

Historically, resource-intensive prototyping (requiring designers and tools like Figma) was reserved for major features. AI tools reduce prototype creation time to minutes, allowing PMs to de-risk even minor features with user testing and solution discovery, improving the entire product's success rate.

Years of focusing on MVPs has weakened the ability of product teams to imagine magical, delightful features. AI prototyping tools make ambitious ideas easier to build, helping teams reignite their creative muscles and aim for awesome products, not just viable ones.
