In the TV series Knight Rider, the concept of an intelligent car was pure sci-fi. Over 40 years later, we now have the tools to bring it to life - purely in the browser. This talk explores combining AI techniques like RAG and function calling with advanced browser APIs (e.g., WebBluetooth) to create a browser-based AI agent with personality, memory, and autonomy, powered by WebAssembly and WebGPU - fully offline and privacy-preserving!

Progressive web apps describe a whole new set of browser features that enable completely new ways of interacting with web applications.While originally intended as an alternative to mobile apps, we are seeing more and more desktop apps that rely on the web platform. Photoshop, Visual Studio Code, Squoosh, Clipchamp and the whole Google Office Suite are just a few examples of a growing number of completely web-based desktop applications - Superwebapps!.In this talk, we will focus on some of the new and exciting browser capabilities that allow us to create powerful React applications that make our daily lives easier. Of course, including tangible examples and an outlook on the browser roadmap.

Machine learning is seen by many as the next step in artificial intelligence towards a new stage of human evolution. And thus helps us find new approaches to solving real-world problems. Phew... That sounds complex… And how is that supposed to be fun?
Well, in addition to the big issues of our time, it is ultimately just another tool that we can play with. While it is important to first understand the core concepts of machine learning, we can quickly go way beyond that. Get ready for some unexpected examples of how to get started with machine learning in your React application!

The WebBluetooth API finally closes the gap between the browser and devices around us. And that suddenly opens up a rabbit hole, in which we inevitably encounter a few hurdles - the story of a frontend developer dipping his toes into the IOT world.
