What is Velo UI
Velo UI turns any UI edits into a structured prompt. Pressing Option+A shows Velo on any site or app; users select the element they want to change, draw, mark, edit text in place or leave a note, and when done, a clean prompt or screenshot is in the clipboard ready for vibe coding. Adding feedback or editing any UI element captures the exact element paths in the auto-generated prompt; text and container properties can be edited for any element; the tool finds all existing components in the app and lets users add or edit them on the page with an auto-generated prompt for the tweaks; visual annotation includes arrows, boxes, freehand drawings and text blocks; screenshots of annotations can be copied or downloaded in 1x, 2x or 4x; and keyboard shortcuts cover toggling the UI, opening an inspector, undo and redo, and quick capture. Gestures let users hold Option to measure dimensions and drag to reposition the toolbar. Velo UI runs fully locally with nothing leaving the browser, collects no user data and has no analytics, accounts or servers. It formats design intent into prompts but does not run AI itself.
