Sidecut Builder
Turn a short brief into a working site or deck, in one chat.
- The problem
- I kept moving between a chat, a design tool and a coding agent to make one good thing. Every hand-off made the next change harder.
- The trade-off
- Keep the work exportable as static files rather than pretend it is a full hosting platform.
- Isolated AI workspaces
- Live previews
- Saved versions
- Brand looks that carry over
How it's built
Builder runs AI-assisted creation in isolated Vercel Sandboxes, previews the output and keeps each finished version. Saved looks carry a brand into the next piece of work.
