Summarise the week

Decision guide

Where it fits—and where it doesn’t.

Best for

Prepare for a meeting

Not ideal for

Unsupervised use with broad sensitive-data access or consequential write actions.

Common setup gotchas

  • Plan, region, role and workspace policy can change what is visible.
  • The live OAuth and action scopes—not this summary—are authoritative at setup.

Permission & privacy notes

Know what you’re opening up.

Schedules, attendees and work records can expose confidential relationships. Start with the narrowest workspace and review every write action.

Connection screens and capabilities can change. Recheck requested permissions at setup, remove access you no longer need and follow your organisation’s data-handling policy.

Platform comparison

Same tool. Different connection.

“Verified” means the tool appears in the official platform catalogue or current first-party documentation. It does not guarantee access on every plan or surface. “Not found” records only what our checked sources showed—it is not a claim of incompatibility.
