🚀 Cut Latency, Ditch the Cloud: Our Hottest AI Tinkerers Demos - July 28

It was a fast-paced demo showing how to build a monetized remote MCP server in a weekend using Cloudflare Workers, Supabase, and Stripe, with Dialer handling outbound calls. Josh Warwick, Ark’s CTO, shared practical notes on a frictionless OAuth flow and tying auth to real backends. Audience feedback was strong about the hands-on value. The talk stood out by showing MCP as a deployable, revenue-ready app and gave concrete patterns for shipping AI-native connectors quickly.

Jacques Joubert, a software engineer at Kigo, demoed his Rust GOAP library, showing how to compose plans from state to action for AI agents across domains. He walked through examples and noted how GOAP could slot into hybrid workflows with LLMs and MCP-style servers. The Rust implementation emphasized performance and clear, testable action schemas. Survey feedback hinted at its approachable, interpretable approach. This was a building block for game AI and automation, with potential for modular agent systems in products.

Aura delivered a cool real-time solution that captured gameplay, recognized screen actions, and provided voice commentary using computer vision, speech recognition, and voice synthesis. Brian—a product manager who loves learning by doing—showcased how open-source tools could run efficiently on consumer-grade hardware. People loved its practical take on multimodal AI integration, and it offered developers a clear blueprint for building interactive, self-hosted gaming experiences that could adapt to a wide range of applications.

Ecocraft Designer demonstrated how AI could streamline NBC-compliant 2D-to-3D floor plan creation. Joseva A, a rising talent from Green Build AI and a civil engineering student, used generative models and AI prompt enhancements to simplify sustainable design. Attendees appreciated the clear technical insights and practical demo that tackled eco-friendly building guidelines. This project showed strong business potential for regulatory automation while offering valuable inspiration for builders interested in sustainable construction.

Craig demonstrated Vibe Coding with Bolt by showing how he quickly turned ideas into visual prototypes that spurred effective customer conversations. His proven experience in data center solutions and project management lent real-world credibility to the demo. People loved seeing how simply a rough code prototype could clarify system designs. This practical approach is a solid reminder for builders that rapid visual communication can bridge the gap between ideation and full development, helping quickly align teams and stakeholders.

Josh Handley showcased Survaize, a demo that used vision models to read survey forms and automatically generate mobile data collection apps. The demo extracted questions and responses from PDFs into a structured JSON format with LLM-based validation. People loved how it tackled tedious manual data entry, and it's a practical example for developers. Josh's solid background as a full-stack engineer shone through, and the project holds promising potential for streamlining survey processes in real-world applications.
