Use cases / Web apps & tools

Build web apps without code — described by you, written by AI

Calculators, dashboards, booking systems, trackers, generators, internal tools. The AI writes real, working code — interactive, stateful, and live on a URL you can share.

Why build it with wish4

It actually works

Not a mockup — working JavaScript with state, logic, and persistence. Multi-view apps with navigation, forms that validate, charts that update as inputs change. If a behavior is wrong, describe the bug in chat and the AI fixes the code.

From idea to shareable URL

Describe the tool, save, send the link. No app stores, no installs, no deploy pipeline — the app is live on the web and works on every device with a browser. Internal tools your team needed for months can exist by this afternoon.

Iterate like a product team

"Add an export button", "remember the user's last inputs", "add a dark theme" — ship improvements by chatting. Each change goes live on save, at the same URL, so users always have the latest version. It's the tight feedback loop of a dev team, without the dev team.

Embed anywhere

Tools live on their own URL, so you can link or iframe them from your existing site. A pricing calculator embedded on your sales page or a quiz in a blog post doesn't require rebuilding your main website. Keep your current stack; add working tools alongside it.

Connect real business data

Through Integrations, apps can work with live data — a dashboard reading your Shopify orders and products, for example, connects through wish4's secure server-side proxy so your access token never appears in the page. Public tools show public data; sensitive views stay owner-only.

Free to prototype, honest to scale

The free plan's $10 in AI credits is enough to build and publish a working tool, no card required. Apps persist data in the user's browser out of the box; for shared or server-side data, connect services via Integrations — deeper backend support is on the roadmap, and we'd rather tell you that than pretend.

Common questions

Is it real code or a prototype? +

Real code. The AI writes complete HTML, CSS, and JavaScript with working logic — state, events, validation, charts. Data can persist locally in the browser via localStorage, and the app runs live on its own URL, not in a sandbox.

Can apps store user data? +

Apps persist data in the user's browser out of the box, which covers trackers, calculators, and personal tools well. For shared or server-side data, connect services via Integrations — for example, Shopify data flows through a secure server proxy. Deeper backend support is on the roadmap.

How complex can apps get? +

Multi-view apps with routing, state, charts, and game logic all work well. The practical limit is clarity, not size: if you can describe the behavior precisely, the AI can usually build it, and you can grow the app feature by feature in follow-up messages.

What does it cost to build and run an app? +

Building uses AI credits — the free plan includes $10 of them, no card required, which covers a first working tool. Hosting is included on every plan. Starter ($20/mo) adds custom domains and credit top-ups; Pro ($99/mo) removes the wish4 badge and unlocks the full agent suite.

Can I put the app on my own domain or inside my site? +

Both. On the Starter and Pro plans you can serve the app from a domain or subdomain you own, like tools.yourcompany.com. Or leave it on its wish4.ai URL and embed it in your existing site with an iframe — no changes to your main stack required.

Do I own the code? Can I take it elsewhere? +

The output is standard HTML, CSS, and JavaScript — no proprietary runtime or lock-in format. wish4 handles hosting and publishing so there's no deploy step, and what the AI builds for you is yours.
