Describe it. Watch it build.

One sentence becomes a running web app.

How it works

Three steps, no setup.

  1. Foldo barking an idea into a big paper speech bubble
    Step 1

    Describe it

    Tell Foldo what you want in plain English. A todo app, a landing page, a game.

  2. Foldo in a hard hat nudging paper blocks into a browser window
    Step 2

    Watch it build

    The code is written and the app runs live in your browser. No setup, no installs.

  3. Foldo balancing a paper plane on the tip of its nose
