Web apps and phone apps
Web apps run in any browser. Phone apps are built with Expo and open on your phone from a QR code while Marky works.
For founders, teams and side projects
AI app builder for web and phone apps
Describe what the app should do and who uses it. Marky builds the screens, the database, sign-in and the server code, tests it in a live preview and publishes it when you approve.
Direct answer
What is an AI app builder?
An AI app builder turns a plain description into a working application instead of a mockup. Marky writes a real project, React and TypeScript for web apps or Expo for phone apps, and adds a Postgres database, sign-in and server code when the app needs them. You try it in a live preview, ask for changes in the chat, then publish it or push the code to GitHub.
Built around the job
What Marky can implement
These are functional product layers tied to the workflow—not decorative sections copied from a template.
Sign-in and accounts
Registration, Google sign-in and screens only members can open, built around how your app is used.
A real database
Marky designs the tables, stores the app's data in Postgres and changes the schema as the app grows.
Server code and integrations
Business rules, private API keys and webhooks stay on the server. Marky connects payments, email or maps when you add their keys.
AI features inside your app
Add chat, image, voice or transcription features through the Easy-Peasy.AI API when the idea needs them.
Preview, versions and publishing
Every change shows up in a live preview. Save versions, roll back, publish to your own address and push the code to GitHub.
Suggested data model
Records the first version may need
- Users
- Accounts, profiles and sign-in identity
- Core records
- The habits, orders, bookings or projects your app manages
- Activity
- History, streaks, comments and notifications
- Settings
- Preferences, roles and connected services
Example prompt
Give Marky a build brief, not a buzzword
“Build a habit tracker web app. People sign in with Google, add daily habits, tick them off and see their streaks. Add a weekly stats page, reminder settings and a home screen with today's habits. Store everything in a database and make it work well on phones.”Use this as a starting point
Practical build sequence
How to build it with Marky
- 01
Describe the app in a few sentences
Say who uses it, the main thing they do and what they should see first.
- 02
Approve the feature list
Marky lists the features it plans to build. Edit, add or remove lines before it starts.
- 03
Try it in the live preview
Click through the app in the preview, or scan the QR code to open a phone app on your phone, and ask for changes in plain words.
- 04
Publish and keep improving
Publish it to its own address, connect a domain or GitHub, and keep adding features in the same chat.
Shared production stack
Standard code, managed launch path
React + TypeScript
An editable frontend, not a proprietary page format.
Postgres + typed APIs
Persistent records and protected server-side logic.
Accounts + secrets
Authentication and protected credentials for integrations.
Built-in publishing targets Cloudflare, and pages are rendered on the server so search engines and AI tools can read them. AWS services can be integrated through protected credentials, and the GitHub codebase can be adapted for an AWS deployment by a developer.
Specific questions
Apps FAQ
Can Marky build a phone app?
Yes. In Build app mode Marky makes the app with Expo (React Native), with a database and server code when it needs them. You open it on your phone by scanning a QR code: in the browser, or in the Expo Go app for the full native feel.
Can I publish my app to the App Store or Google Play?
Not from Marky. You can publish the app at its own web address and push its code to GitHub. Getting it into the stores takes an Apple or Google developer account and an Expo build, which a developer can make from that code.
Is Marky a vibe coding app?
Yes, in the sense that you describe what you want and the AI writes the code. Marky also sets up the database, sign-in and hosting, checks its work in a browser, and lets you keep the code.
Do I need to know how to code?
No. You describe the app and ask for changes in plain words. The code is a standard React and TypeScript project, so a developer can pick it up later if you want.
Is the AI app builder free?
You can start on the Free plan, which has a small monthly allowance. An app is a long job (screens, a database, sign-in and testing), so finishing most apps takes a paid plan. Paid plans also add the strongest models and commercial use.
