Case study from a real project: How we built a fully functional video application in one day using AI tools. Process, tools, and lessons learned from practice...
How did a whole promo video come from 2 photos and an MVP app within 8 hours? What used to take weeks and cost hundreds of thousands, you can now do in a fraction of the time and cost. At Appmine we show how to do it in practice.
Let's look at how for Volba spotřebitele (Consumers' Choice), the largest marketing programme in the Czech Republic and Slovakia, we created a complete digital campaign with the help of AI and saved up to 80% of costs.
What are we talking about? Volba spotřebitele is not just any event
Volba spotřebitele is a marketing giant that has been honouring the best novelties on the fast-moving consumer goods market for 25 years. In the jubilee 2025 edition 256 products from 201 companies competed in 66 categories. The results are based on a survey among 4 000 respondents in the Czech Republic and decide which products get the prestigious logo on their packaging.
When they approached us with a request for a creative campaign, we knew we had to deliver something exceptional. And we showed that AI isn't just a buzzword, but a real game-changer.
Section 1: A video from 2 photos: how we bypassed traditional production
At the start we had just two product photos. No crew, no cameras, no studio. The goal? To create a dynamic promo video including an animated thumb, the iconic symbol of Volba spotřebitele and part of their logo. Our process looked like this:
1.Midjourney Editor: From the product photos we created several variants of key visuals. Thanks to that we could "choose the actors" and the setting without having to cast anyone.
2.Kling & Sora-like tools: We set the selected visuals in motion with AI video generators. Here we ran into the classic teething problems of AI, character consistency, image flickering, deformed hands and problems keeping the logo. The solution? Iteration, patience and smart post-production.
3.Post-production: Here we were lucky and could hand the video over for editing to experienced partners from Studio | Store Media and in collaboration we handled the edit together, for both the CZ and SK versions.
The value for the client is huge. Classic production of a similar video would cost hundreds of thousands, actors, location rental, a film crew, expensive post-production. We got to a fraction of that amount
Section 2: A Starter Pack MVP in 8 hours: a joke that showed the power of AI
We needed to quickly show what an app could look like. Instead of weeks of development we built in 8 hours a fully functional MVP in the style of a funny "Starter Pack", an app that was more of a fun element for the presentation than a serious product. How?
•Lovable + Cursor: We combined the no-code platform Lovable with the AI-powered development environment Cursor. Thanks to that we could create the user interface in a flash and connect it to the backend.
•API problems? A creative solution! During the presentation the API went down for a moment. Instead of panicking, we turned it into a joke and showed live how fast we can react. The presentation ran for a while "on a password", but everyone saw that even with unexpected problems we can cope in real time.
The value? Huge. We showed that in a few hours we can create a working prototype of anything, from a funny app to a serious business tool.
Section 3: What value does an AI workflow bring to companies and IT agencies?
Combining AI and rapid prototyping is not just a technology toy. It brings real business value to all types of companies:
•Cost saving: We're talking tens of thousands of euros on a single project. Money you can invest in further development or marketing.
•Speed: From weeks to hours. React to trends, test new ideas and stay a step ahead of the competition.
•Flexibility: Did the brief change halfway through the project? No problem. With an AI workflow, changes are quick and cheap. You can afford to experiment.
•Competitive advantage: While others wait for a supplier, you are already testing and iterating.
For context: Volba spotřebitele has such an influence on the market that 79% of traditional retailers confirm the positive effect of the awarded logo on sales and 83% of retailers list the awarded products. When you create a campaign for such a client, every euro and every day counts.
Section 4: What to take away from this?
Companies and IT agencies need not be afraid of AI. Quite the opposite. It is a tool that can be elegantly plugged into existing processes and bring immediate results. Whether you need to speed up creative, cut production costs, test new ideas faster or just entertain someone at a presentation with a funny app, AI is the answer.
The key is the right implementation and understanding the possibilities. That's why we offer workshops and implementation bundles that show you how to do it in your company. The ROI is practically immediate. Let's get in touch and work out what we can do for you: I WANT HELP WITH AI.
