How to Design UI with AI Like a Pro: 2026 Guide

The best UI design tools in 2026 are powered by AI. In fact, even legacy tools like Figma are layering AI. On the other hand, I’ve designed a thousand UI interfaces over my career (viz., since before Figma) and tested hundreds of viral apps’ UI. And, in this guide, I’ll take you through the steps that professional designers (like myself) follow to use AI for generating hi-fi UI — iteratively, from idea to export; that works for both designers and non-designers. 

I’m going to design a mobile app UI live using one of the best AI UI designers, Banani AI, around the idea:

A payment app UI like Cash.app with key screens to send, receive, and manage money; plus their desktop & dark mode versions as well.

1) Ideate Fast, Wireframe Faster

Or, described the step in full: Ideate fast on paper first, then turn it into a wireframe – even faster – with AI.  

When I get a brief, I let my mind loose to visualize the first screen of the app and draw it on paper as quickly as possible. It can be rudimentary, incomplete, and even something you might scrap later. Yet, I believe, anything that helps me bypass the blank-screen problem is good to go.

Like a rough sketch above: uneven boxes for sections, doodles for images/icons, and squiggly lines for copy. And take it directly to Banani AI as an input to draw a wireframe:

1. Open Banani, and upload the sketch as reference

2. Type “Convert this sketch into a wireframe” and Enter↵

3. Answer the 2-3 clarifying questions asked by their AI UI Agent

And, in seconds, your hand-drawn sketch will be turned into an editable wireframe. 

You can see all my ideas from the hand-drawn wireframe are preserved. But it’s not perfect. So I edit it — by chatting with AI. No design skill needed in it. 

Also, notice Banani has created design assets on sides. These components will be referenced for other screens and variations as we expand our design, much like a Design MD file.

2) Edit by Asking an AI Agent

The interesting part about editing wireframe with AI is that you can explore a couple of ideas fast. Like, initially I had wanted the sections to occupy the whole of the screen, but looking at the digitized wireframe, I feel, some important element can come there like recent transactions or star-marked contact. So, I simply prompted it to:

“Create me two variations of this screen:

1. Make the top box bigger. The two buttons should occupy the whole row. And the rest of the squares fit below without leaving any empty space. 

2. Make the top box a bit bigger, and adjust the other boxes in a way to include a row of tags/pills with the name of the star-marked contact. And below that a list of recent transactions.

The nav bar everywhere should have icons for: home, card, money, search, history.”

In under a minute, both versions are there. Next to each other, easy to compare. And, now, I like the second version better, so shall proceed with it to turn it into a high-fidelity version. (At this point, I’d delete the rejected versions.)

By the way, in Banani, you can import a Figma-made wireframe of a single screen, and explore its variations with AI chat.

3) Share Visual References for UI

Satisfied with the lo-fi wireframe now, I’ll go for the hi-fi interface. Now, I have two options: 

1. Simply ask for it in AI chat. Need not even tell the color palette. The AI will take care of it. 

2. Upload some UI references to direct the style, color, typography, and iconography.

Depending on how much time I have and the specificity of the requirement, I’ll do either. For the sake of demonstration here, I’ll show a version for each. 

*My prompts for the two versions:

a) “Turn this into a high fidelity UI of an app with a minimalist, fun & bold personality"

b) “I want a hi-fi UI out of this wireframe styled in line with the image attached.  Specifically maintain the translucent card/screen properties.” 

That said, many times, I take my ideas straight from brief (a text description + image references) to hi-fi UI and then iterate with AI. No intermediary wireframe or lo-fi design.

4) Get full flow & desired screens

Both of them are stunning, ain’t it? I like the green one (b) better. And shall proceed with expanding other screens along this style. So, first I deleted the rest of the screens. And typed in the Banani AI chatbot:

“I like this style for the money management app that I am making. Please create 3 more screens:
1. Sending money to a contact. Show the screen where the recipient is already selected and the user has to enter the amount to be sent. 

2. Show my card status. I want to see a proper digital debit card with its details. Underneath it some action buttons for managing the card. And past transactions.

3. The in-app Stocks feature. Dashboard of the user’s gains, losses as a pie chart. Their stocks, and possible action buttons."

And just like that, within 3 minutes, I had three more key screens for my app. Notice how intelligently Banani’s AI UI Agent filled in on some of my vague prompts like ‘...some action buttons’.  

Dark Mode UI

To get the dark mode version of my (light) mobile screen, I select all four of them and prompt: 

“Give me 4 new screens that are exact duplicates of these four but in dark mode.”

Desktop Version of the UI

Converting a mobile UI to its desktop is always a pain I personally try to avoid. But with an AI UI designer like Banani, it’s as convenient and fast as clicking a button. Because Banani comes with a pre-defined option of ‘Generate Desktop’ for all mobile UI (and vice versa for desktop UI).

Below is how it converted the homescreen of my app’s UI from mobile to desktop view.

Again, without any prompt at all, notice how smartly it chose the layout and even added additional sections in line with a typical dashboard of a fintech app. You can create the desktop version of multiple screens in a go by selecting them all and asking for it in the prompt. 

Looking at my whole canvas, I take a sigh of relief that we have AI tools for UI. 

Because something that would have taken me a full day to complete with traditional UI tools is done in minutes with an AI UI tool. And I can create as many more features’ UI as I need — without losing the fidelity and style.

5) Share, Export & Hand-off

Once happy with the UI, I take it forward to my team for further development both in terms of design and code – all from within Banani AI. 

i) Create the link to view and copy the canvas from the 'Share' button on the top right.
ii) Export the design to Figma for further tweaks and integration into your Figma workflow. 
iii) Copy clean & semantic HTML/CSS code in a click to accelerate the front-end development.
iv) Transfer the design to an AI coding agent via MCP for developing a functional app.

What are the main features of an AI UI generator? 

When looking for an AI UI Generator, some key features to consider are:

Text-to-UI generation, image/screenshot-to-UI, wireframe mode, design system support, convert to Figma, and export to code.

What are the benefits of an AI UI generator? 

Compared to conventional UI tools, AI UI designers offer: Speed (idea to screen in minutes), a lower barrier for non-designers, faster iteration cycles, and reduced back-and-forth before developer handoff.

How to design UI in Figma with AI? 

Two ways: use Figma's native AI features to generate screens inside Figma, or design in a dedicated AI tool like Banani and export directly to Figma with one click.
