One shared build day across AI Tinkerers chapters worldwide, run locally in Paris with OpenAI, CopilotKit and OpenRouter backing it. The brief: ship a working agent inside a tool people already use, then submit a repo, a two-minute video and a written description by the end of the day. The Paris room is the city's production-AI crowd, engineers and technical founders who bring code rather than decks. Venue is private and shared after you register, so sign up early.
