Developer Builds Digital Twin of Geneva with 15 AI Agents
Swiss developer Arnaud Ricci has created Genève 3D, a digital twin of the canton of Geneva, using 15 AI agents in his spare time since July 2026. The interactive browser application displays buildings, roads, trees, and moving trams, trains, and airplanes, as well as current weather. Ricci primarily used Anthropic's Claude model, directing the agents as a manager. The project, which would have taken two to three years without AI, was completed in about three months. Data is sourced from over 15 public institutions including Meteoschweiz, Swisstopo, EUMETSAT, and NASA. The platform uses Three.js and loads data on demand, but requires human oversight to correct errors and manage hardware limitations. Potential use cases include education, tourism, and urban planning.
The article demonstrates a novel use of AI agents for rapid software development, but it is a single developer's hobby project with limited direct impact on the AdTech industry at large.

AI Usage in Switzerland Doubled
The IGEM-Digimonitor 2026, published by IGEM and WEMF and based on an Intervista survey of 1,957 respondents in March–April 2026, finds that AI adoption in Switzerland doubled from 40% (2024) to 80% in 2026. Usage is highest among 15–34 year-olds (91% use occasionally, 44% daily). ChatGPT is the leading AI platform in Switzerland (reported 4.3 million users and 67% occasional usage), followed by Gemini, Copilot, Claude and Perplexity. The study also reports growing use of AI in search (77% use AI-mode in classic search engines; 57% use standalone AI platforms) and a decline in willingness to pay for digital news across demographic groups. The report documents shifting media consumption toward streaming and social platforms among younger groups.
AI Built App from 5-Line Memo in 45 Minutes
A developer published a demo showing an open-source framework, gr-sw-maker, which used multi-agent AI workflows to convert a five-line memo into a browser-only Earthquake Map application, a spec and tests in 45 minutes. The process relied on an agentic SDLC pattern with specialized AI agents (architect, security reviewer, test engineer, etc.), six quality gates, and an AI-native spec format (ANMS) that uses EARS, Mermaid and Gherkin. Deliverables included functional requirements, Gherkin scenarios, unit tests and high code coverage. The project is portable across several agent runtimes (Claude Code, Gemini CLI, Cursor, Windsurf) and requires Node.js and Claude Code to reproduce. The author frames this as Spec-Driven Development (SDD) within an agentic SDLC workflow.
Beginner Builds 10 AI Apps in Five Days
A developer recounts building ten generative-AI projects in five days while working through the IBM Applied AI Developer Professional Certificate. Projects included a Finance Tracker, Sentiment Analyzer, Emotion Detector, Image Captioner, Chatbot, Voice Assistant, Meeting Assistant, Translation Assistant, Job Application Coach and a locally hosted private RAG (Retrieval‑Augmented Generation) application. The author documents practical hurdles: poor responses from Meta's BlenderBot model, an inaccessible IBM translation API leading to a Whisper+Piper workaround (requiring an ONNX model file), and a breaking LangChain API change that moved imports to langchain_classic. The post emphasises the difference between passive learning and hands‑on building, noting how debugging real projects revealed gaps in conceptual knowledge and shaped next learning steps.
