Dex gets dramatically more useful when it can see your real calendar, meetings, and tasks. Every integration is optional, each takes a few minutes at most, and each has a setup command that walks you through it conversationally — you never edit configuration by hand.
A principle worth knowing up front: your credentials stay on your machine. API keys live in a local file that's excluded from any syncing or version history, and for most task apps Dex has you save the key directly to that file yourself rather than pasting it into chat.
Calendar (Mac)
What it gives you: your real meetings inside /daily-plan and /meeting-prep, including recurring events like your weekly 1:1s.
How it works: Dex reads the Mac's built-in Calendar app — so any account added there (Google, Outlook, iCloud) flows through. Two steps: add your work account to Calendar (Calendar → Settings → Accounts), then grant calendar access when your editor asks. Run /calendar-setup to grant a speed permission that makes calendar reads near-instant.
Honest limits: Mac-only. There's no Windows calendar integration today.
Granola — automatic meeting memory
What it gives you: the biggest single upgrade in Dex. Granola captures your meeting notes and transcripts; Dex syncs them automatically, extracts decisions and action items, and keeps person pages current — including meetings you take on your phone. This powers /process-meetings, enriches /meeting-prep, and feeds your weekly review.
What it needs: a Granola Business or Enterprise plan — only those plans can create API keys (the free plan can't). Run /granola-setup: you create a key in Granola's settings, Dex verifies it works, and daily background sync can be installed so meetings arrive without you doing anything.
Google Workspace — email-aware planning
What it gives you: your daily plan knows about email — unread counts, threads waiting on your reply, follow-ups that have sat unanswered for two days. Meeting prep pulls recent email context with attendees. Dex can also draft emails, create events, and write docs — always showing you before anything sends.
How it works: run /google-workspace-setup (about three minutes). It signs in through Google's standard authorization screen in your browser; the resulting token is stored locally.
Task apps — Todoist, Things 3, Trello
If you already live in a task app, Dex syncs with it two ways: tasks you create in Dex can appear there, completions flow in both directions, and tasks from your app come back through your daily plan. Sync happens when you ask ("what's due in Todoist today?") — Dex doesn't poll in the background.
- Todoist —
/todoist-setup, about two minutes, works everywhere. You'll copy an API token from Todoist's settings into your local key file. - Things 3 —
/things-setup, under a minute, Mac-only. No account or key at all — it talks to the app directly, and can map your pillars onto Things areas. - Trello —
/trello-setup, a couple of minutes. Maps your board's lists onto task statuses (Backlog / In Progress / Blocked / Done).
Meetings and messaging
- Microsoft Teams —
/ms-teams-setupfor a chat digest. - Zoom —
/zoom-setupfor recordings and scheduling. - Jira + Confluence —
/atlassian-setupfor ticket context.
Anything else — the open door
The connections above are the built-in ones, but they're not the boundary. Dex speaks MCP, an open standard with a large public marketplace of ready-made connectors (Notion, Linear, Slack, GitHub, and hundreds more):
/integrate-mcp— connect a ready-made connector from the marketplace or a link./create-mcp— no connector exists? Dex builds one with you, live, from the tool's documentation. No coding on your part — and the Make Dex your own page covers this properly.
Don't know what to connect? Ask what's possible
The best integration ideas don't come from a feature list — they come from showing the AI your toolbox and asking what it would build:
List every tool and connection you can currently reach in this vault. Then, knowing my role and goals: what are the five most valuable workflows we could set up that I'm not using? For each — what it does for me, what it needs connected, and the setup effort. Rank by payoff, and be honest about what my current tools can't do.
Make it your own: rerun it after every new connection — each tool multiplies what the others can do, so the answers genuinely change.
Choosing what to connect first
Dex personalizes its own suggestions during setup — it looks at which apps are installed and which tools your notes mention, and offers the highest-value two or three. If you want a simple rule: calendar first, Granola second if you have it, then your task app. Those three cover the daily loop. Email is a strong fourth once you trust the system.
Don't just read this — paste it into your own Dex and it becomes a lesson about your actual work.
First, fetch and read the page I'm referring to: https://heydex.ai/help/integrations.md I just read the Dex Guide's integrations page. Take stock of MY situation: which connections do I already have, which am I barely using, and — given my role and what my notes say I do all day — which single missing connection would pay off most? Make the case in two sentences, tell me honestly what it needs from me (accounts, plans, permissions), and if I say yes, walk me through connecting it right now.
