What do you like best about Trillian?

I can quickly contact my coworkers to deal with a problem. Review collected by and hosted on G2.com.

What do you dislike about Trillian?

The app pops up and consumes way too much screen real estate. I have to minimize that thing every day. Review collected by and hosted on G2.com.

"Straightforward IM Solution"
4/5
What do you like best about Trillian?

Very easy to use. Very reliable. Robust set of tools. Review collected by and hosted on G2.com.

What do you dislike about Trillian?

No major downsides. You can format IMs in bold, italics and such, but only if you CTRL+B, CTRL+I, etc. It'd be nice if that was shown as an option. Maybe some better organization of group IMs as well. They get a little messy as they accumulate over time. Review collected by and hosted on G2.com.

4.5/5

Trillian on-prem server with the security and control you need to meeting compliance regulations. Review collected by and hosted on G2.com.

What do you dislike about Trillian?

That the rest of the world does not use Trillian. The lack of mass corporation adoption means you can only message inside your organization or other Trillian users. Review collected by and hosted on G2.com.

"great instant messaging alternative to achieve a good reach on the platform."
4.5/5
What do you like best about Trillian?

I love the way how we can work on this software because we can have better communication with each of the employees and potential clients. After all, if we can improve each service and the quality of technical support through text messaging, it has a maximum of features that allow us to have control of everything immediately and automatically. Review collected by and hosted on G2.com.

What do you dislike about Trillian?

Specifically and without inconveniences I have nothing against the application since it led us to have constant communication and without any problem with employees and clients, it has a great user interface since it is very easy to use and has a great advance of modernity Review collected by and hosted on G2.com.

"Inexpensive and fully featured HIPPA compliant chat software"
5/5
What do you like best about Trillian?

This software is similar to slack in its features and appearance and is far less expensive to make HIPPA compliant than slack is. It's fully featured, offers group and private group channel-based chats, and even provides an emergency contact option which is helpful to our healthcare workers. Review collected by and hosted on G2.com.

What do you dislike about Trillian?

The second panel is a bit complicated to get used to initially, if you have used slack before it will quickly get familiar but there are enough differences to be confused with it at first if you are not tech-savvy. Review collected by and hosted on G2.com.

"Gets the job done! Could definitely improve, but I am satisfied!"
4.5/5
What do you like best about Trillian?

I really like that it is instantaneous. I also appreciate that you can enter a quick little status such as "in a meeting" or "Out of Office today". I work for a virtual school and this is what we use to talk to our staff members instantly! Review collected by and hosted on G2.com.

What do you dislike about Trillian?

I really hate the whole "add me as a friend" thing. I completely understand that this platform isn't necessarily meant directly for businesses. But I had SUCH a struggle when we'd get a new team member, and they wouldn't add me back on Trillian, so I would have no way to get in contact with them. Another weird thing is, on Microsoft desktop app at least, there's no indication that someone has added you as a friend, so they'd never get the notification. On my personal Macbook, it changes my status for when I am active. But for my microsoft desktop app, it does not change instantly. Review collected by and hosted on G2.com.

"Easy to use and comprehensive"
4.5/5
What do you like best about Trillian?

I find Trillian easy to use and pretty intuitive. I like that you can set your status and mute groups as needed. It works great for our team, as we have to divide the workload between different departments across buildings. Review collected by and hosted on G2.com.

What do you dislike about Trillian?

I wish we could change the avatars for the specific groups we created. But, other than that, I don't have many complaints. The visual user interface is easy to use, but not super modern looking. Review collected by and hosted on G2.com.

"2022 Trillian Review"
4.5/5
What do you like best about Trillian?

I like that it is available on my desktop, laptop, and my cellphone; this way I am always able to get messages from co-workers don't have to be at my work desktop or logged into my laptop to get messages. I like that you can have groups set up by departments at the office for example all of the lab technicians simply set the group and then just select group title to send to that department. Review collected by and hosted on G2.com.

What do you dislike about Trillian?

I honestly haven't come across anything that I don't like or that I have any issues with at this time. Review collected by and hosted on G2.com.
