Generated screens are fast, and they're someone else's idea of your product. You spend the time you saved undoing guesses.
Wireframely is built for the part of design where you decide what goes on the screen. You place every component, in the order you mean, and the tool makes that quick: a library of real components, Stacks that keep spacing for you, snapping, frames for every screen, and a one-click trip into Figma.
If you want to drive it from an AI assistant of your own, the MCP server lets it place components through the same library. The screens are still built from parts you can see, edit and own.
