Tettra is excellent for a small team wiki. It is easy to set-up and use, and for many teams the free version is enough. New features are added regularly. One of the features I would like to see is 2FA for email accounts or even SAML integration.
In our company, we host our benefit articles based on country on our Zendesk Guide. However, these articles should not be seen by employees that are outside their respective article country. For example, an employee that is based in Thailand shouldn't be seeing Malaysia benefits article as employees might compared benefits. With Zendesk Guide, the system allow us to set the configuration of the article so it is only visible Thailand-based employees, and for Malaysia article, only Malaysia-based employees
They give us ability to control the whole frontend of the Communities by giving us access to manipulate HTML (in HBS file), CSS and JS
They give handlebars templating engine in backend which helps us to show various listing rendered through server side without having need to implement client side rendering of the listing and features.
They provide us dynamic content fields, which can be useful for mapping categories or storing category and topic IDs so we don't need to hard code IDs in Sandbox and Production separately.
I base the rating on the online availability of the help system. The product is quite intuitive but the questions I did have were answered on the online help. That is always better than having to contact support as then you have to wait longer than just a search on the website.
The support is good but can sometime be frustrating to get a quick answer. We end up being sent articles that don't answer the question and then we have to go back and try again
Tettra provides an easy interface, but feels limited in its feauture set. When I need to incorporate more granular permissions or live collaboration I use Google Drive.
It is an attribute of Zendesk that allows for easy over the phone communication between agents and customers. It is more personal and allows for better productivity. Phone support from anywhere with reliable internet connection which is essential to call center communication whether in the office or in the home of the agent.
