Integrations that should not exist
Half the integrations in a productivity app exist to compensate for the fact that the app does not read the calendar. The calendar already is the integration.
Every time a productivity app boasts "200+ integrations", it is confessing something: it knows nothing about your day on its own. It needs Slack, Notion, Linear, Jira, Trello, Asana, GitHub, Figma and fifteen more to piece together what should have been in one place from the start.
The calendar as source of truth
Google Calendar and Apple Calendar already know where you need to be every hour. Gmail already knows who has written to you and what they want. Google Tasks already knows what is on your plate. If an app can read those three things, it knows everything it needs to plan your morning.
Connecting Slack adds no information that email does not already have. Connecting Notion adds no tasks that Google Tasks does not cover. Connecting Linear adds no meetings that the calendar does not know about. Those integrations exist because the app in question does not read what is already there.
The real cost of each integration
Every new integration is one more OAuth token the user has to authorise, one more attack surface the company has to audit, and one more failure point the support team has to diagnose when it stops working. It is not free: it is technical debt dressed up as a feature.
And the worst part is the cognitive cost. A settings panel with fifteen integration toggles produces exactly the same anxiety as a full inbox: am I missing something by not connecting Asana? Should I turn on GitHub? The user ends up enabling everything just in case, exactly like they read every email just in case.
What you actually need to connect
For a personal planner, the essential connections are four:
1. Calendar — To know where you need to be and what comes next.
2. Email — To know what is being asked of you and what is pending.
3. Tasks — To merge Google Tasks with Todoist if you use both.
4. Weather — Because a rainy day changes the plan when you have outdoor meetings.
Everything else is noise dressed up as functionality. If your human secretary does not need access to your Figma to plan your day, your AI secretary does not need it either.
That is exactly what we do at Madrugo: connect what matters and the briefing writes itself. You can read more about how it works at what an AI secretary actually does.
