A Chrome workspace extension that acts as a second brain, remembering context, tasks, and helping you move work forward.
Dex (branded as a "second brain" for Chrome) turns the browser into a unified AI workspace that captures context across tabs, surfaces relevant information, and helps users organize and act on tasks. It maintains memory of your tasks and context so the assistant can provide targeted suggestions, quick summaries, and workflow shortcuts directly in the browser. Dex aims to reduce context switching by linking notes, bookmarks, and active tasks to page context and by offering search and retrieval of past interactions to accelerate decision-making and execution.
