AI App Maker: Describe Your App, Get One That Works

Mythex is an AI app maker: you describe the app in plain words, it writes a full-stack app you can click through in a live preview, and one click puts it on a public URL. It attaches a real database and file storage, so sign-ups, records and uploads are actually saved, not faked on screen.

Who it's for

People with an app idea and no developer on hand: a founder who wants something real to show first users, a shop owner tired of tracking orders in a spreadsheet, a coach whose clients need to log in. Developers use it as well, to skip the first week of setup and then take over the code on Pro.

What you can build

A client portal where customers log in and see their orders and invoices
A booking app with time slots, a calendar and a confirmation page
An internal tracker that replaces the team's shared spreadsheet
A SaaS MVP with sign-up, a dashboard and a settings page
A member directory with profiles, photos and search
A habit or workout tracker that keeps each user's history

How the AI app generator works

You start with a message, not a template picker. Say who the app is for, what people do in it and what it should remember. Mythex plans the screens and the data, writes the code, and shows the result in a live preview while it builds. From there you keep talking: “add a status filter”, “only admins can delete”, “make the header darker”. Each change shows up in the preview, and when it looks right you press Publish.

Describe the app in one message, in any language
Watch it build in the live preview
Change anything by chatting
Publish to a public URL in one click

A free AI app builder, without coding

The Free plan needs no credit card. You get 5 credits a day (10 on your first day, up to 30 a month), unlimited projects, the live preview and publishing. That is enough to build and publish a first version and share the link. It is not unlimited: when the day's credits run out, you continue the next day or move to Pro. You never have to write code on either plan, though you can read every file Mythex writes.

Free: 5 credits/day, unlimited projects, preview and publish
Pro, $25/month: 100 credits/month plus daily credits
Credit top-ups on Pro when you need more

An app creator that keeps real data

Many AI app creators stop at screens. Mythex attaches a real database and file storage to the project, so a sign-up form creates an account, an order lands in a table and a photo upload is stored. Hosting, databases and storage are paid from monthly Cloud credits (10 on Free, 20 on Pro), so there is no separate hosting bill to set up before your app goes live.

When you outgrow the chat

The code editor and terminal sit next to the chat. On Free they are read-only; on Pro you can edit the code, export the project, push it to GitHub and connect your own domain. Pro also turns a published app into an Android app and an iPhone app, so the same project can reach phones without a rebuild. Mythex remembers who you are and how you work across projects, so a second app starts faster than the first.

A prompt to start from

Build a web app for a small cleaning company. Customers sign up, request a cleaning with an address, date and notes, and see the status of each request. Staff log in to a dashboard where they accept requests and mark them done. Use a real database and make it work well on phones.

Questions

Is there a free AI app builder with no limits?

No honest one, because every AI build costs real compute. Mythex Free gives you 5 credits a day (10 on day one, up to 30 a month) and unlimited projects, with no credit card. Pro is $25/month for 100 credits a month plus daily credits, and you can top up.

Can I make an app without coding?

Yes. You describe what you want and ask for changes in plain language; Mythex writes and fixes the code. The code is there to read if you are curious, and editable on Pro if you or a developer want to change it by hand.

What kind of apps can an AI app maker build?

Apps where people sign in, enter data and see it again: portals, booking systems, trackers, dashboards, directories, internal tools and SaaS MVPs. Mythex builds these as full-stack web apps with a database and storage, published to a public URL.

Can it make phone apps too?

Yes, on Pro. Mythex turns your published app into an Android app (a file you upload to Google Play) and an iPhone app sent to TestFlight with your own App Store Connect key. The phone app opens your published app, so every Publish updates it.

Can I build with Mythex from ChatGPT or Claude?

Yes. Connect Mythex from Account settings on any plan and it works inside ChatGPT and Claude, and also from Cursor and Codex. The sandbox tools there need Pro.
