What if your browser knew your entire workday — and could quietly handle the parts that drain your focus?
In this episode of First Commit, Eliya Elon and Laura Hamilton sit down with Regina Lin, co-founder and CEO of ThirdLayer, the company building Dex — an AI workspace that lives inside Chrome and acts as a true knowledge worker for the browser.
Regina started building Dex as a college side project with her co-founder Kevin while juggling a math degree and years of competitive piano performance — originally just trying to get GPT-4o to order DoorDash at midnight. The insight that it could replace entire categories of manual, browser-bound work crystallized when they snuck into a Boston AI conference with fake lanyards and ran into someone managing hundreds of UiPath bots. What Dex became is a hybrid agent that pulls context directly from the browser while executing actions through precision tool calling — not screen scraping, not MCP — built for the knowledge workers who spend every minute of their day living in tabs.
