Bolt.new is magic for prototyping. Describe what you want, and watch it build a working app in your browser in real time. It's the closest thing to 'just tell the computer what to build' that actually works.
The catch: what it builds is a great starting point, not a finished product. Complex business logic, authentication flows, and database design still need human expertise. But for MVPs, internal tools, and 'let me see if this idea works' — it's incredibly fast. The fact that everything runs in the browser (no local setup) is the real killer feature.
