Caffeine AI Lisbon: A Full-Day Event Exploring the Self-Writing Internet and the Future of AI-Built Applications

Caffeine AI, in collaboration with Internet Computer, ICP Hubs Network, and ICP Hub Portugal, announces Caffeine AI Lisbon, set to take place on November 9, 2025.

This one-day experience invites builders, creators, and AI enthusiasts to explore the Self-Writing Internet, where applications are built through natural conversation instead of code.

Powered by Caffeine, the first full AI tech stack, the event will demonstrate how artificial intelligence can transform ideas into production-ready applications for both technical and non-technical participants.

Caffeine AI Lisbon combines learning and innovation through hands-on sessions and interactive experiences.

The day begins with the Caffeine Promptathon, a collaborative challenge where participants use AI prompts to build functional applications across three tracks: Commerce Apps, Personal Apps, and Community Apps.

A $2,000 prize pool and exclusive Caffeine merchandise await the top projects.

Beyond the competition, attendees can look forward to:

• Live demos showcasing the Self-Writing Internet in action
• A panel discussion on “Web 4.0: Designed by AI” featuring leaders from the AI and Web3 space
• Networking opportunities with developers, investors, and innovators
• An evening celebration with music, food, and conversation

At its core, Caffeine AI Lisbon celebrates accessibility and creativity. The event shows that app development no longer belongs solely to coders. Anyone, whether a founder, designer, or entrepreneur with an idea and curiosity, can now build with AI as a collaborator.

It’s a chance to experience a new era of human–AI co-creation.

As part of Web Summit week, the event highlights Lisbon’s growing reputation as a European hub for AI, blockchain, and next-generation Internet technologies.
