AI app builders promise to turn a description into working software. They differ enormously in what kind of app they actually produce well, and picking the right one matters more than picking the most hyped one.
Match the tool to the app
A simple internal tool, a form that writes to a spreadsheet, a dashboard on one API, is a genuinely good fit for most current builders. A consumer product with real accounts, payments, and complex logic is a much harder target. Treat an app builder as capable of fast internal tools and prototypes, not full production consumer apps without real engineering added on top.
Where the category is actually heading
Google cancelling its standalone AI Studio app in favor of building the capability into Gemini directly is a clear signal: app creation happening mid-conversation with an assistant you already use, not a separate destination.
Three questions worth asking before you commit
- Can you actually export the code, or does it only run inside their platform?
- What happens as the app grows past a quick prototype?
- Does a targeted change actually stay targeted, or does it regenerate parts you didn’t touch?
Build the smallest useful version first and test it thoroughly before layering more on top, the same caution that applies to any AI-generated code.
