Nullstack

Viola UI is a Figma UI kit for fintech and AI products: investing, trading and portfolio screens built around one dataset instead of a dozen disconnected mockups. Most kits fake their numbers screen by screen, so they quietly stop matching. In Viola UI, one portfolio feeds every screen. The...

Questions & Answers

As answered by people managing Viola UI and Nullstack.

Why should a person choose your product over its competitors?

Viola UI's answer

General-purpose kits give you buttons and cards. Viola UI gives you finished fintech screens: investing, trading, portfolio, transfers, fund research and documents. AI copilot patterns are built in. It has 45 screens, each in light and dark, 440 component variants, 42 colour tokens and 23 text styles, all made with real Figma variables and components. Because the data reconciles, you can use it for realistic prototypes and user testing, not only for visual inspiration.

What makes your product unique?

Viola UI's answer

Every screen in Viola UI runs on one portfolio dataset. The dashboard, holdings table, fund page and AI copilot all show the same €48,203.11 portfolio, so the numbers agree with each other in light and dark. Most UI kits fill each screen with its own placeholder numbers, and those stop matching once you put the screens side by side.

How would you describe the primary audience of your product?

Viola UI's answer

Product designers and design teams working on fintech, investing, trading and wealth products, and founders who need credible financial screens quickly. It’s also for teams adding AI assistants to financial apps.

What's the story behind your product?

Viola UI's answer

I'm Kseniya, a UX/UI designer with seven years of experience. I kept seeing the same problem in fintech mockups: every screen had its own made-up numbers, and they never added up from one screen to the next. So I built Viola UI around a single portfolio. The dashboard, the holdings, the fund page and the AI copilot all draw from the same data and agree with each other, in light and dark. I wanted a kit that a fintech team could use for realistic prototypes, not just for inspiration.

Which are the primary technologies used for building your product?

Viola UI's answer

Figma: variables with light and dark modes, components with variants, auto layout and text styles. The typeface is Geist.
