Agents, Everywhere: Global Hackathon

One shared build day across AI Tinkerers chapters worldwide, with the São Paulo room running its own seven hours of it. The brief is to ship an agent into a place people already work and talk, Slack, WhatsApp, a browser, rather than another chat window, and OpenAI, CopilotKit and OpenRouter put credits and tooling behind it. AI Tinkerers is a builders-only room with a no-pitch rule, so you sit next to engineers and technical founders who are actually shipping. Free, RSVP required, venue address goes out once you are in.
