Step by step
How to build an app with AI, step by step
Five steps from an idea to a published web app.
- Step 1
Create a free account and describe your app
Sign up for free, then type what you want the way you'd explain it to a person: who uses the app, what they need to do, and what data it keeps. For example, a small tool for tracking client invoices, with a login for your team. There's no template gallery to scroll through first.
- Step 2
Let Kleap generate a first version
Kleap builds the screens, the database and the sign-in your description calls for, then opens the result next to the chat as a live preview rather than a mockup.
- Step 3
Refine it by chat
Keep chatting to change it: add a field, rename a button, rewrite a section or try different colors. The same preview updates with each request. Generation and edits use AI credits, and no code editor is required.
- Step 4
Test it like a user
In the preview, click through every screen, submit the forms, and add and edit records. The preview shows signed-in pages without a real sign-in and does not run server routes, so check access rules again on the published site, with a second account. If something is off, describe it in the chat and ask Kleap to change it.
- Step 5
Publish it to a real URL
Publish for free on an address such as yourbusiness.kleap.io, with hosting included. Connecting your own domain requires a paid plan. You can export the code or sync it to GitHub whenever you want.
From scratch
What "built from scratch" actually means here
Some tools that promise you can build an app from scratch still start you from a template: a pre-built layout with placeholder text and stock sections that you then edit into shape. That's customization of a structure that existed before you typed anything.
Kleap works the other way. When you describe an app, the AI writes the layout, the copy, and the styling for that specific prompt. A bakery site and a consulting firm's site can have different layouts and features, while using the same underlying platform infrastructure. What you get reflects what you asked for.
That doesn't mean unlimited scope. Kleap can generate websites and apps with database, authentication, and connected services. Your prompt defines the features, and you still need to check the result against your requirements before publishing.
Comparison
How Kleap compares to Bubble, Lovable, v0, and bolt.new
If you're weighing how to build an app using AI, these five tools are the ones that come up most. All let you build without hiring a developer, but they start from different assumptions about who's building and what for. This is pulled from each product's own pricing and docs, not a ranking.
Kleap(this site)
- How you build
- Describe the app in a prompt, then describe changes the same way
- Free plan
- Yes: 5 AI credits a day, up to 30 a month; generation and edits use credits
- Publishing
- Yes, free on a *.kleap.io URL; a custom domain requires a paid plan
- Best fit
- Business websites, landing pages, portfolios, SaaS apps, and internal tools
Bubble
- How you build
- Drag-and-drop visual canvas — you wire up the database and workflows by hand
- Free plan
- Yes, on a limited free plan
- Publishing
- Yes, hosted by Bubble
- Best fit
- Web apps and SaaS products that need custom backend logic
Lovable
- How you build
- Prompt-based code generation (Vite + React), typically paired with a Supabase backend
- Free plan
- Yes, with limited monthly credits
- Publishing
- Yes, one-click deploy
- Best fit
- Supabase-backed prototypes, internal tools, and React apps
v0 (Vercel)
- How you build
- Prompt-based UI and app generation, built around Next.js and the Vercel ecosystem
- Free plan
- Yes, with monthly credits and a daily message cap
- Publishing
- Yes, via Vercel deployment
- Best fit
- React/Next.js teams already building on Vercel
bolt.new
- How you build
- Prompt-based generation that runs in the browser via WebContainers
- Free plan
- Yes, with monthly tokens included
- Publishing
- Yes, hosting is bundled in
- Best fit
- Builders who want a browser-native AI coding workflow with hosting attached
Bubble is the closest to a traditional no-code platform here: building means wiring up a visual canvas and a database yourself, which gives you more manual control over backend logic than Kleap currently offers, at the cost of a real learning curve. Lovable and v0 both generate application code (React or Next.js) that's typically paired with a separately configured database service. bolt.new runs the whole workflow in the browser. Kleap brings the prompt, live preview, database, and authentication into the same creation workflow. You can build screens to create, read, update, and delete app data, then test the behavior in preview.
Full pricing and feature detail for each of these tools lives on the alternatives page.
Honest scope
Where Kleap fits, honestly
A quick reality check before you start typing: some ideas are a good match for a first version you can test quickly; others need more detailed requirements and validation.
Good fit
- A business site, portfolio, or landing page today
- A waitlist or pre-launch page for an idea you're testing
- A small SaaS product with a database and user accounts
- A simple internal page or form your team can use
Not built for
- A visual workflow canvas for manually connecting database operations
- A finished enterprise system without configuring and testing its approval rules, permissions, and integrations
- Automatic App Store or Google Play submission; publishing a web app does not complete a native app release
If what you need is a working site or small tool published today, free to start, this is built for that. If you need a visual database schema builder or a workflow automation canvas wiring together many systems, a platform built specifically for that job will serve you better than stretching a prompt-based tool to cover it.
FAQ
Frequently asked questions
Can I build an app with AI for free?
Yes, to start. With a free Kleap account you get 5 AI credits a day, up to 30 a month, and you can publish your app for free on a kleap.io address. A custom domain needs a paid plan, and the Pro and Business plans add AI credits. Connected services such as Stripe may charge their own fees.
How much does it cost to build an app with AI?
With an AI builder, the main cost is AI credits, not developer hours. On Kleap you can build and publish a first version on the free plan. Paid plans add a custom domain, and the Pro and Business plans add AI credits. Budget separately for any paid APIs your app calls, such as payments or email.
Can ChatGPT build an app?
ChatGPT can write code, but you still have to assemble it, set up a database, add login and host it yourself. An AI app builder such as Kleap does those steps for you: it generates the app, runs it in a live preview and publishes it to a URL.
Can I use AI to make a mobile app?
Kleap builds web apps that run in any browser, including on phones, and can be added to a home screen. It does not produce native iOS or Android apps for the App Store or Google Play. For store-listed apps you need a native or cross-platform tool.
Can I build an app from scratch without starting from a template?
Yes. Kleap doesn't require you to choose a template before you start. You describe what you want, and the AI generates the layout, copy, styling, and app features for that prompt, using the platform's shared infrastructure.
How is this different from Bubble or Lovable?
Bubble is a visual canvas: you drag on elements and wire up a database and workflows yourself, which gives you more manual control over custom backend logic. Lovable generates React code that's typically paired with a Supabase backend you configure separately. Kleap brings app generation, database, authentication, and hosting into a prompt-and-preview workflow. You describe the features you need and configure access to any external services you connect.
Do I need to know how to code?
No. You describe what you want in plain language, and you describe changes the same way afterward. There's no code editor you're required to open to build, edit, or publish your site.
What can't Kleap build?
Kleap can build websites, SaaS apps, and internal tools with a database and authentication. A complex enterprise system still needs its requirements, permissions, and connected services configured and tested. A prompt alone does not guarantee every business rule or integration is ready to use.
