Overview

Replay addresses the limitations of static screenshot-to-code tools by introducing a "video-first" workflow. Instead of relying on single frames, Replay treats video as the source of truth, analyzing screen recordings over time to reconstruct not just the visual layout, but the full behavior, animations, and user flows of an application.

The platform combines generative AI with temporal analysis to break down video input into actionable UI components. It detects dynamic elements such as hover states, cursor movements, and content transitions that static prompts miss. To ensure a premium finish, users can choose from a selection of stunning, pre-configured design styles, allowing the AI to automatically apply high-end aesthetics to the reconstructed interface.

The reconstruction engine maps these visual cues to production-grade libraries like Radix UI and Framer Motion. To further enhance the accuracy and maintainability of the output, every result is generated as a structured, componentized project rather than a single flat file. Replay supports a modern stack—exporting directly to React, Tailwind CSS, and TypeScript - providing developers with a foundation that is architecturally sound.

Replay is designed with the objective of saving developers the days of effort typically spent on rebuilding UI boilerplate and reproducing complex animations. It provides a robust platform that marries the speed of generative AI with the precision required for professional software engineering.

It generates clean, readable code akin to that of a senior frontend developer, and allows easy refactoring and extension. It enforces a pragmatic non-speculative approach to UI creation, avoiding invented structures and speculative layouts. Moreover, its ability to enable visual redesign without affecting layout integrity sets it apart from other UI building tools.

How does Replay convert video footage into production-ready UI?

Replay converts video footage into production-ready UI by treating the video as the source of truth and examining the video over time, rather than just single frames. It analyzes pixel-level layouts and complex interactions within the video footage, and uses this information to construct the user interface. This includes generating clean, componentized code, a visible design system, and both desktop and mobile previews.
