I'm Jason Arbon — entrepreneur, technical cofounder of Testers.ai, co-author of How Google Tests Software, and obsessed with AI and Quality. I've spent my career building and scaling test infrastructure at the world's largest software companies, was Head of Product & Engineering at Applause, built a team of some of the best testers in the world, and was funded by Google's Gradient Ventures for test.ai. Now I'm building AI that tests software autonomously.
These are personal projects and experiments — Chrome extensions and iOS apps that explore how large language models can reshape the way we consume and evaluate content online. Each app leverages multiple AI providers (Claude, OpenAI, Gemini) so you can choose the model that works best for you.
