Vizu — AI Photo & Video Maker
Full product redesign: from outdated UI to a live App Store product with AI-generated effects, video creation, and an in-app coin economy.
Overview
Vizu is an AI-powered app that transforms photos into styled images and videos using generative effects. I joined the project without a product manager — which meant owning not just the design, but product decisions, feature logic, and the entire visual direction. I led a complete redesign of the existing app and took it from an outdated interface to a polished, launched product currently live on the App Store.
The Problem
The original app had an outdated visual design that didn't match the quality of its AI capabilities. There was no coherent product logic, no monetization structure, and no clear user journey from onboarding to creation to purchase.
The Goal
Redesign the full product experience — modernize the UI, create an intuitive creation flow, design and produce all AI effect previews, and build an in-app coin economy to monetize premium effects.
Process
Result
The redesigned app launched on the App Store and currently holds a 4.3 rating with user reviews praising the creative effects and AI photo packs. The project was delivered in 2 months — from concept to live product.
Before → After
The redesign replaced a generic, low-trust interface with a visually compelling product that communicates AI quality at first glance. Below is the original app — rebuilt from scratch in the new direction.
AI Effects — Onboarding & Creation Flow
The core experience starts with a simple onboarding that introduces the app's AI capabilities. Users select a photo, choose an effect, and see the transformation in real time. The flow was designed to minimize friction and get users to their first "wow moment" as fast as possible.
Coin Economy — Monetization System
I designed and defined the full logic of an in-app currency system from scratch. Coins are earned through engagement and purchased via IAP — they gate access to premium AI effects. The system needed to feel fair and transparent while driving purchase conversion. Every state — balance, spending, low-coin warning, purchase confirmation — was fully designed and specced.

AI Effects Library — 40+ Styles
All AI effect previews were produced by me using Runway and other generative tools. Each preview is a real output of the effect — not a mockup. The library covers portrait transformations, artistic styles, cinematic looks, and seasonal themes. Quality of the preview directly drives the purchase decision.
App Screens
A selection of screens from across the app — showing the variety of UI states, interactions, and layouts designed as part of the full product redesign.
Desktop Web Interface
Beyond mobile, the product was extended to a desktop web interface — giving users access to the same AI effects and creation tools from a browser. The desktop layout maintains visual consistency with the mobile app while adapting the experience for a larger canvas and mouse-based interaction.
