Dex
ПодтвердитьDex is a Chrome-based AI workspace for managing tasks, context, and browser workflows in one place.
What Dex does
Dex is a Chrome-based AI workspace from ThirdLayer, Inc. that is positioned as a second brain for browser work. Its stated purpose is to hold tasks, context, and operational knowledge in one place so the assistant can help move work forward.
The public site shows Dex as a browser extension with AI agent capabilities, plus related touchpoints such as iMessage and a Slack bot. The product is sold in usage-based plans with integrations that sync into a context system, and the higher tiers add more automation, scheduling, support, and privacy controls.
