Watt is building Layer 3 of the reasoning layer using Vercel's open-sourced agent-browser.

Watt is where you find out what people are actually doing. Ask any question about a market, a category, or a brand's buyers in plain English, and get an answer grounded in real behavior: what people actually search for, shop for, and buy. For years the most valuable signal, the record of what people really do, sat locked inside a few giants. Google knows what we search. Meta knows what we click. Hedge funds know what we buy. Everyone else has been left to guess. Watt opens that up: 172,000 live signals across 250M+ US adults, refreshed daily, in a chat anyone can use. LLMs index what people say. Watt indexes what people do. Every answer is grounded in real behavior you can check. Growth teams, marketers, founders, and the agencies serving them use Watt to see who's really buying, what they buy next, where demand is moving, and what changed, then make the business call based on evidence instead of a hunch. The best ideas should win. We're here to make sure they do.
