Yes. Gmail is one of Heidi's integrations: she reads mail you connect, remembers what matters with sources and permissions, and folds it into the one brain every team and every AI tool reads from. A new system connects in hours, not months.
Once Gmail is connected, its knowledge stops being an island. Commitments made over email stop vanishing into inboxes: the promise to a customer is on record with its source.
Permissions carry over from the source, and every remembered fact keeps its receipt, so answers built on this data are checkable.
