AI-built app

An app whose code was written by an AI assistant from your prompts, then run as real software.

Definition

An AI-built app is a working application whose code was generated by an AI assistant from your descriptions and edits. It might start as a vibe-coded prototype, a Claude artifact, a Cursor project, or a Copilot session. What makes it an app, not a demo, is that it can be deployed: it has a URL, can store data, and people can use it without sitting in your chat window.

Why it matters

AI makes it cheap to create internal software that used to wait months for a developer. The hard part shifts from writing the first version to hosting and operating it safely. Without private hosting, backups, and access control, an AI-built tool that touches invoices, payroll inputs, or client lists becomes a liability. Teams need a clear place to deploy, share, and revise these apps.

How Croft fits

Croft is private hosting for AI-built apps. Connect the assistant you already use, deploy onto your own server, and get company login, SQLite-backed data, backups, and rollback without assembling a stack. Pricing starts from $24/mo annual on Solo, with Team at $99/mo annual and a 7-day trial. See AI app hosting for the product view.

FAQ

Frequently asked questions

What counts as an AI-built app?

Any app whose code came mainly from an AI assistant you steered, whether that started in Claude, ChatGPT, Cursor, Grok, Copilot, or similar tools.

How is an AI-built app different from a chat preview?

A preview lives in the session. An app is deployed: lasting URL, database, and a way for other people to sign in and use it.

Where should I host an AI-built internal app?

On private app hosting with team sign-in and backups. Croft is aimed at that use case for SMEs and finance teams.
