Buyer’s guide
Prompt-to-app is not the same as AI-in-your-editor
AI editors work inside an existing codebase: they read your files, follow your conventions, and edit in place. Prompt-to-app builders generate a working application from a description and host it for you. The first is for developers with a repository; the second is for getting from idea to demo without one. Choosing the wrong shape wastes the budget entirely.
The four questions that decide it
- Do you already have a codebase? If yes, you want an editor that understands it, not a generator that starts fresh.
- Where does it end up? Some tools deploy and host; others produce code you must take elsewhere. Check whether you can export and own the result.
- How is usage metered? Requests, tokens, or "fast" premium model calls — heavy days hit limits quickly and the fallback model is usually noticeably weaker.
- Who reviews the output? Generated code still needs reading. These tools change how fast you write, not whether the result is correct or secure.
The honest caveat
AI-generated code is confident about things that are wrong, and it will happily produce insecure patterns. Treat every diff as a pull request from a fast, tireless junior developer: valuable, and never merged unread.
