Turn tabs into automated workflows and tasks

Overview

What it is

Browser extension that proactively organizes tabs, shortcuts workflows, and handles tasks for you. Your digital mind in Chrome. Turn your browser into an AI command center.

Intent

I need it when

Reduce meeting prep time and ensure follow-ups are never missed

Before every meeting, Dex pulls full history from emails, past calls, and open commitments. After meetings, it automatically sends follow-ups using call notes and writing tone. Users report saving 5+ hours per week on meeting prep alone.

Automate repetitive cross-tool workflows without manual context switching

Dex creates autonomous agents that orchestrate across Gmail, Slack, CRM, and 20+ tools, triggered by events or schedules. Browser control lets Dex navigate tabs and fill forms directly, eliminating manual data entry and context switching for tasks like CRM updates, email drafts, and meeting scheduling.

Maintain operational memory and context across fragmented work tools

Dex ingests and structures all datapoints (messages, meetings, deal updates, workflow events) into an Operational Graph that serves as a living source of truth. The Knowledge Manual captures priorities and SOPs, enabling Dex to reason across past precedent and relationships when executing tasks, so context never gets lost.

Scale personal productivity without hiring additional staff

Dex functions as a second brain for high-leverage work, automating task triage, data entry, and workflow orchestration. The Full Service tier provides white-glove setup and ongoing optimization, effectively delivering a team of EAs at a fraction of hiring cost.

Get proactive work suggestions and continuous workflow optimization

Dex's Dreamer Agent reasons 24/7 over new data to maintain context and spot emerging patterns. The Skill Builder Agent generates custom automations and suggestions weekly based on repeated workflows, continuously optimizing setup without manual intervention.

Drop

Not a fit when

  • User needs offline-first functionality; Dex requires browser and cloud connectivity
  • Organization requires on-premise deployment without custom setup; private cloud available only at Ultra tier and above
  • Team has fewer than 3 people and needs shared operational intelligence; Teams & Enterprise features are in limited early access
  • User works primarily outside web browsers and integrated apps (Gmail, Slack, CRM, Linear); Dex is browser-centric
  • Organization cannot commit to monthly subscription; no perpetual license or one-time purchase option exists
