By enabling teams to share live, clickable prototype URLs, Stripe shifted its design reviews away from static Figma presentations. This "Demos, Not Memos" approach allows stakeholders to interact with the product directly, leading to more tangible and higher-quality feedback.

Traditional "writing-first" cultures create communication gaps and translation errors. With modern AI tools, product managers can now build working prototypes in hours. This "show, don't tell" approach gets ideas validated faster, secures project leadership, and overcomes language and team barriers.

The traditional workflow (Idea -> PRD -> Alignment) is outdated. Now, PMs first create a functional AI prototype. This visual, interactive artifact is then brought to engineers and scientists for debate, accelerating alignment and making the development process more creative and collaborative from the start.

The team no longer relies solely on PRDs and design docs. Product managers are now required to build a functional prototype as a core part of the development cycle, ensuring ideas are validated with a working model early on.

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.

Product Requirement Documents (PRDs) are often written and then ignored. AI-generated prototypes change this dynamic by serving as powerful internal communication tools. Putting an interactive model in front of engineering and design teams sparks better, more tangible conversations and ideas than a flat document ever could.

The product management workflow is evolving from documentation to creation. With AI tools lowering the barrier to build, PMs can now develop and share functional prototypes to communicate ideas and test assumptions, a much higher-fidelity approach than traditional written documents.

For complex features, a 17-page requirements document is inefficient for alignment. An interactive AI-generated prototype allows stakeholders to see and use the product, making it a more effective source of truth for gathering feedback and defining requirements than static documentation.

The ability to rapidly prototype with new tools has fundamentally changed meetings at Block. Instead of presenting information via slides, teams bring working prototypes, which allows for real-time interaction, exploration, and deeper, more tangible discussions.
