Glean

What it does

Glean indexes mail, drive, chat and wikis, then answers with citations while inheriting permissions from the source system. The model is not the hard part — connector coverage and access control are.

Priced per seat and sold to companies rather than individuals. It starts paying for itself once a team is big enough that 'where is that file' costs real hours every week.
