Guru is pretty solid

Its search functionality, its tagging capability as well authentication, security and compliancy are 2nd to none! Where I feel Guru falls a tiny bit short is not everything about it is super intuitive such as building out cards. But it is very reliable and consistent, you can be confident if you set up your cards or groups correctly it will do the job.

In companies in tech it be useful, or generally companies with lots of teams and different protocols. Generally not useful for simple products. Being able to share knowledge, empower staff and make it easier for other people to do their job is where it comes out on top. On smaller teams, under 5 people, it be a bit less useful.
