Why use Kombai if my agent can already write UI code?
Left on their own, agents fall back to AI defaults. Kombai’s taste agent identifies the key design decisions for each task and makes high-quality choices instead. You can explore directions on Kombai’s canvas before they touch your production code, and Kombai applies your design system so new work stays on brand.
Will the designs match my existing product?
Yes. Kombai can detect the colors, type, spacing, and components your codebase already uses and save them as a design system. It applies that design system to new work, so every design stays on brand.
Can I see what Kombai designs?
Yes. When your agent starts or checks on a Kombai chat, it can give you a link to that chat and its design canvas. The Kombai desktop app must be running with the chat’s project open for the link to work. If Kombai has a question, your agent asks it in your chat and sends your reply back, or you can answer it in the Kombai app.
