It is very easy to use in combination of multiple channels such as Slack, Skype etc with chat windows that are customizable into various shapes or sizes depending upon our preference. The user interface has been designed quite well keeping all basic necessities at front so there's no issue we face while integrating it within existing communication tools like MS Office 365 (Slack) & others. I wish their team can build an advanced version by adding more functionalities which they have recently launched some days back without considering about its impact before launching them publicly without proper testing. As i mentioned earlier - this tool has enabled us from having to create custom apps in order to integrate those things since MarBot supports everything within one window itself making it less messy rather than creating different app versions and hence reducing efforts. The ease of use, the ability to organize our meetings and share documents with colleagues who are in different time zones. I love that it is integrated with MS Office 365 and can be used with other platforms like Google Docs. There is nothing that I dislike about this product. I would highly recommend. We have been able to quickly set up a virtual office where we can communicate and collaborate seamlessly. This has helped us improve productivity and reduce costs by not having to rent additional space.
