What Dex by Thirdlayer is
Dex is a Chrome extension that turns the browser into an AI workspace. It connects applications and works across tabs, so instead of jumping between tools you stay in one place and Dex handles the handoff. It remembers your preferences and context, then predicts and executes the next operation, sometimes before you ask. The concrete features are practical: notes saved and retrieved without friction, meetings scheduled in seconds, LinkedIn profiles scraped into Google Sheets, personalised bulk email sent through Gmail, and meeting briefs assembled from calendars, profiles and email threads. It is privacy focused, with fine-grained permissions over your data, and a free plan sits below the Professional, Business and Enterprise tiers.
What you can do with it
- Work across connected apps without switching tabs
- Save, organise and retrieve notes quickly
- Schedule meetings and generate briefs automatically
- Build prospect lists from LinkedIn into Google Sheets
- Send personalised bulk email from spreadsheet data
Who it is for
- Knowledge workers who live in the browser
- Recruiters and salespeople building lists and doing outreach
- Students organising research and meetings
- Professionals who want predictable busywork removed
What to watch out for
It runs in Chrome, so if your organisation standardises on another browser this will not fit. Scraping profiles and sending bulk email must respect platform terms and privacy rules, and the consequences of ignoring them fall on you, not the tool, so use it for legitimate outreach only. Automated actions should be reviewed before they send, since a wrong recipient list is hard to undo. The free plan has limits, and heavier automation work belongs on a paid tier.
