What does Stitch actually do?
Stitch addresses a common early-product problem: the team has an idea, but not enough visual material to judge whether the idea actually works on screen. A written spec or verbal description often sounds fine until someone has to translate it into a mobile app flow, a landing page, or a dashboard layout. That translation step is where momentum dies. Stitch tries to close that gap by giving you a way to turn a prompt or a reference image into a UI concept quickly enough that discussion can start while the idea is still fresh.
Its strongest use is fast design ideation, not deep authoring. You can choose app or web, enter a prompt, upload an image, explore template starters, and generate directions that give the team something concrete to inspect. That matters when the goal is to test product framing, screen hierarchy, or visual tone before investing in a longer manual design pass. In that context, speed is the feature. A rough but usable concept in minutes is often more valuable than a perfectly reasoned brief that still has no screens attached to it.
