Vibe Coder or True Dev?
20 questions, 30 seconds each. Find out how well you really know what's under the hood of an LLM.
The Idea
Everyone says they "work with AI." Few can explain how it works.
There's a gap between shipping with AI and understanding it. So I turned that gap into a game: a fast, slightly cheeky knowledge check covering tokenization, attention, embeddings & RAG, agents, prompting, fine-tuning, and benchmarks. The stuff that separates a vibe coder from a true dev.
How It Works
Answer, get ranked, share your persona.
A 30-second timer per question keeps you honest. Your score maps to one of six personas, from Vibe Surfer to Transformer Architect, with a shareable result card and a daily streak to bring you back. A Supabase-backed leaderboard updates in real time as players around the world finish.

Ferros AI
Owners text a change, the menu updates itself in every language, instantly.
The Problem
Menus change daily. Updating them doesn't.
Small restaurant owners deal with seasonal menus, daily specials, and multilingual guests, but updating a PDF menu takes time they don't have. Guests scan a QR code and find yesterday's menu with last quarter's prices.
The Solution
One WhatsApp message. Live menu, instantly.
The owner texts: "Add grilled sea bass, €22, today's special." The AI parses it, updates the live database, regenerates translated versions, and the QR code reflects the change within a few seconds. No dashboard, no training.

Erin AI
Clients book via Instagram DMs, zero manual replies from the salon.
The Problem
Salons live on Instagram. Bookings still live in their heads.
Croatian beauty salon owners get most clients via Instagram, but convert them through long manual DM threads: checking availability by hand, sending reminders at midnight, dealing with last-minute cancellations.
The Solution
Erin handles the entire booking conversation.
When a client DMs, Erin responds with services, checks real-time availability via Acuity, confirms the slot, and sends a 24-hour reminder. The salon owner only sees confirmed bookings.

Legal Claims Automation
Damage claims that took an hour now process automatically in under a minute.
The Problem
Paralegals spend an hour per claim on data entry.
A personal injury law firm receives dozens of damage claim documents weekly: medical bills, repair estimates, lost income statements. Each requires a paralegal to read, extract key figures, and manually enter them into Clio. Slow, error-prone, and expensive.
The Solution
An n8n workflow that reads documents like a paralegal.
A document lands in a folder, Document AI extracts text, Claude identifies and validates claim fields, and the Clio API writes structured data to the correct matter record. Low-confidence extractions surface to a human review queue.

Kompas AI
An AI assistant that monitors Croatian legislation and answers accountants' regulatory questions.
The Problem
Accountants can't keep up with constant legal changes.
Croatia's official gazette publishes new laws and amendments daily. Accountants need to track tax, labor, and regulatory changes across dozens of laws, but reading the gazette manually is time-consuming and easy to miss critical updates.
The Solution
AI that reads the gazette and answers your questions.
Kompas scans Narodne novine daily, classifies changes with AI, and sends email alerts filtered by relevance. Its RAG-powered assistant lets accountants ask natural-language questions and get answers grounded in actual law text and official interpretations.

Welcome Book
One QR code in the apartment, a complete guest guide in the visitor's own language.
The Idea
Guests arrive with a hundred questions. One fridge magnet answers them all.
My mother-in-law rents holiday apartments on the Croatian island of Pašman, and every guest asked the same things: Wi-Fi password, check-out time, the nearest beach, where to eat, when the ferry leaves. So I built one digital welcome book: guests scan a single QR code in the apartment and instantly get apartment info, prices, house rules, beaches, restaurants, activities, ferry times and useful contacts.
How It Works
Scan once, read it in your own language.
The guide detects the visitor's browser language and opens in it automatically, with a sticky switcher across English, German, Italian, Slovenian, Polish and Czech. Phone, WhatsApp and Google Maps are all one tap away. There's no backend: each owner's guide is a single editable content file, so the whole thing can be cloned for a new apartment in minutes.

Stack Digest
Your AI and dev tools change every day. One morning email tells you what actually matters.
The Problem
Your tools change under you. You hear about it when something breaks.
A modern app leans on a dozen AI and dev services: Anthropic, Vercel, Supabase, Clerk, OpenAI, Twilio. Each ships breaking changes, deprecations, outages and price hikes on its own schedule, and nobody has time to watch a dozen changelogs and status pages.
The Solution
One daily email, every update rated red, yellow or green.
Stack Digest pulls the official release notes, changelogs and status feeds for the tools you actually use, lets AI rate each update by how much it could hurt you, and emails you a single morning digest with the reds first. Pick your stack, get the signal, skip the noise.

Prompt Shot
Draw on your screen, paste an annotated screenshot straight into your AI coding assistant.
The Problem
"Fix this bit" is hard to say in words.
When you ask an AI assistant to fix a UI (align this, change that angle, move this button), describing the exact spot in words is slow and vague, and a plain screenshot doesn't point at anything. Existing tools either freeze the screen, push you through a popup editor, or look like a keylogger to antivirus.
The Solution
Hotkey, scribble in red, paste. Done.
Press the hotkey and the screen dims into a live overlay, no freeze, no popup. Draw freehand in red, hit Enter, and a clean full-colour screenshot with your marks lands on the clipboard, ready to paste into Claude. A resident daemon keeps it instant. Built in an afternoon, then open-sourced for other developers.
