Local desktop apps
Four apps, four trades — one philosophy: the work stays yours.
We build software for different trades — SEO, plumbing quotes, painting estimates, digital creativity — but they all share one principle: the app works for you, the data is yours, you pay once or not at all.
- Free plan on all
- No card to download
- Public roadmap
What ties them together
Three principles, four apps
-
Local-first where it makes sense
The desktop apps (Deviz Instalator, Deviz Zugrav, Creative School) run 100% locally — your data stays in Program Files on your machine. Analiza 360 is SaaS because it analyzes data that already lives in the cloud (Google Ads, Meta, GA4) — we can't bring local what doesn't leave the cloud.
-
AI with your own key
Wherever we use AI (SEO Co-pilot, quote suggestions, learning assistant), the app uses your own API key with your chosen provider. You pay the provider directly, not us.
-
One-time payment or free
All apps have a free plan with essential features. For pro features, you buy a one-time license, no forced subscription. Cancel anytime, no card-on-file.

Why this ecosystem?
We're not an "all-in-one" platform for everything. Each app solves a concrete problem for a concrete trade.
We build them all with the same philosophy: respect for the user, a free plan that doesn't expire, AI with your own key, and a public roadmap. Because that's what we believe is missing in today's software.
When you buy a physical tool — a car, a saw, a mixer — you own it. Software should work the same way: you pay for it fairly, it's yours, no one takes it from you if you forget a bill. That's what we do here.
