AI Coding Tools
These take a description and return a working application rather than helping you write one, and they are the half of this category that grew fastest. Bolt.new is the quickest route to something running on a URL. Lovable produces output good-looking enough to show customers. Emergent holds together on projects where the other two start breaking things. Rork is the only one that builds for mobile. All four charge in credits or tokens, all four spend them on failed attempts as well as successful ones, and all four have a complexity ceiling you will eventually meet. Plan to hand the result to a developer if the idea works.
Best for prototypes and internal tools built by someone who can read JavaScript
Bolt.new is a browser-based AI builder for websites, web apps and Expo mobile apps, suited to fast prototypes by people who can read code. It runs a Node.js environment in the browser tab, and editing code by hand costs no tokens.

Best for founders without a developer who need an app with a real backend

Best for founders who want a native phone app but do not write Swift or Kotlin
Rork is an AI app builder that turns plain-English prompts into native iPhone apps in SwiftUI, Android apps in Kotlin and web apps in React. It suits founders without mobile developers, and it builds and uploads store releases on its own servers.
