Your AI doesn't know which button you mean
SlimSnap is an innovative AI-powered tool designed for UI/UX designers, product managers, and developers who frequently work with screenshots and annotations. Unlike traditional image recognition tools, SlimSnap reads your screenshots as pixel blobs and intelligently guesses which button or element you are referring to, based on your annotations. It then converts the visual input into structured JSON, detailing element coordinates, unique IDs, and specific points of interest like arrows. This process streamlines the documentation of UI flows, bug reports, and design specifications by transforming visual annotations into machine-readable data. Its on-device operation ensures privacy and quick processing, while the open-source schema and Claude Code integration encourage customization and extensibility. With a free Mac app and a focus on simplicity, SlimSnap is particularly appealing for teams seeking accurate, machine-readable UI documentation without relying on cloud-based solutions.
