Dexの事業内容

ThirdLayer is an applied research and product lab building the next interface for human - AI collaboration. Our first product is Dex, an AI copilot for the browser. Think Cursor for knowledge work, optimized for speed and embedded directly where you work. Most web agents are built for set-and-forget tasks. But real work is fluid and messy - spread across tabs, tools, and evolving decisions. Dex transforms your browser into an intelligent, multimodal workspace that understands your intent through voice, text, and action. It enhances familiar interfaces, automates tedious steps, and removes the friction of handoffs. Beneath the surface, Dex is more than a browser agent - it’s a foundation for: ● Long-term, cross-modal memory grounded in real workflows ● A new interaction layer to replace static UI with a collaborative canvas ● Personalization: understanding how individuals approach tasks and navigate software We're building the infrastructure for adaptive, intent-aware systems that work the way you do.

What is your company going to make? Please describe your product and what it does or will do.

We are building Dex, an AI copilot inside the browser that helps people work faster and more fluidly across tabs and tools. It understands inputs via voice, text, and actions, automates tedious steps, and builds a long-term memory of how users work to personalize and simplify knowledge work.

Where do you live now, and where would the company be based after YC?

We currently live in San Francisco. After YC, the company will remain based in San Francisco.

Explain your decision regarding location.

San Francisco is where we both live and where our users tend to be. It's also a hub for high-intensity knowledge work that uniquely needs our product.
