Kuvio Studio
AI-powered image editing for real estate professionals, architects, and furniture makers – Virtual Staging, Declutter, and atmosphere transformations in seconds instead of days
The Problem
Real estate agents show empty rooms, architects only have sketches, furniture makers need product photos in various settings. Traditional staging costs €500-2000 per property and takes days. US-based AI tools often lack GDPR compliance and don't understand the European market.
The Solution
Kuvio Studio transforms photos in seconds with specially trained AI prompts: Virtual Staging fills empty rooms, Declutter removes chaos, Twilight mode creates perfect evening atmosphere. One credit = one transformation. Hosted in Germany, GDPR-compliant, no hidden costs.
Results
Architecture
Full-stack TypeScript with TanStack Start for SSR and Server Functions. Google Gemini as primary AI model for image generation. Supabase for auth, storage, and PostgreSQL database – all hosted in Germany. Credit-based billing with transparent pay-per-use structure.
Challenges
- • Prompt engineering for consistent results: Each transformation needs precise prompts that work reliably across different input images
- • Anti-hallucination for furniture: The AI model must not alter existing fixtures – only add or remove what's requested
- • Intensity levels: Three levels (Minimal, Moderate, Full) for each tool, all requiring different prompt strategies
- • DACH market focus: Marketing and UX completely tailored to the German market, not just translated
Learnings
- • Spin-off from maklerupdate: The idea emerged while observing agent listings – empty rooms sell worse
- • Gemini is surprisingly good for image editing: Consistent results, good prompt adherence, affordable API costs
- • Credit system > Subscription for this use case: Users want to pay when they need it, not every month
- • B2B AI in the DACH market: GDPR compliance and German support are real differentiators
