Most founders trying Claude for the first time stop at the chat window. They miss the actual unlock: connectors. With them, Claude reads your inbox, your calendar, your CRM, your docs and your projects, and acts on them. Without them, you keep copy-pasting into chat like it's 2024.
How to add one
Open Claude Cowork. Settings → Connectors → Browse → Add. Pick from the list, sign in, grant the permissions you're comfortable with, done. Most installs take under 30 seconds. Start with three. Add a fourth when you find yourself wishing for it.
Comms and calendar
The connectors you'll touch every working day. If you only install three things, install these three.

OpsSchedules meetings, manages RSVPs, pulls tomorrow's calendar straight into a morning brief.
Slack
CommsSends messages, fetches channel history, pulls threads into the chat instantly. Ends a lot of "let me check Slack" tabbing.
