President

The ease of deployment was the best feature. The administrative console was user friendly, and easy to navigate.

Medical practitioner 

It help to build a strong connection and good trust. Little bit get enjoy chatting through this software during office time.

Licensed Agent/Customer Service Representative

The only criticism that I have is that you cannot just delete unwanted old conversations. You have to leave the group and then it sends out an alert to the others.

Admin

Customer friendly and easy to use, find it friendly and interesting. Glad my company has selected office chat.

Secure way to send message to team overseas. Love the document attachment, emoji's are great.

Travel Agent 

Price is very good also. One thing I REALLY like is that it shows two green ticks once it has been delivered so that I know it has actually reached the other person and I dont need to follow it up.

Executive Officer

Finally, the live chat support is incredible. Chatting with a real person  who can walk you through any use of the product and takes your live feedback is outstanding, especially for the cost.

Designer

I like the ease of sending my coworkers messages that can be shorter than emails, especially because we are all remote.

We have had a great experience and wonderful integration.

Surgeon

It was a great integration product for our office.

Franchise Owner

I like the file-sharing capability and administrator settings.

Addictions Recovery Facilitatoy

Even if Office Chat is open as one of the other apps running in the background, it will minimize the other apps and impose itself for no apparent reason. Notably, I have an Android phone.

Cost Effective & Easy Solution To Keep Your Team In The Messaging Loop.

PT, Clinic Director

We like this to communicate in our therapy office, it is quick and easy to use.

Owner

Its reliable and easy to login. You can group people easily and review older messages.

Administrator

I love how easy it is to set up a user. There's no learning curve.

Business Coordinator

There are some glitches we have noticed. Sometimes the notification badge will appear when there is no new message.

Editor

When I was added to a pre-existing chat, I always had a notification for a new message even though there was no new message and I couldn’t get rid of that.

Director of Programs

It's a wonderful, smooth, secure alternative to Slack - perfect for our growing community.

PhD Student

All in all, we have had a great experience since switching to Zulip. Especially, the organization of messages helps us to stay on top of things in times when there's a lot to handle at the same time.

IT Supervisor

Great Way to communicate with my co-workers from the job, love the small integration it has, its easy to use.

Community member

The chat functionality in the web client is awesome for distributed teams - well, for any team, actually. Splitting in topics, all the formatting options, integration of automation really great.

Professor

I learnt of Zulip because of its use by the Lean community, where it has been superb.

I chose Zulip as an open source solution with a good cloud hosting experience and have very happy.

We really love threading model which is main difference over slack we used before. Recent conversations" and "Public streams" are great features I didn't saw elsewhere.

Team Member

My experience with Zulip is very good. It helps to keep track on discussions and keeps them organized.

Awesome platform for communication, has been really easy to use for communicating in one of my classes.

For researchers like me, the built in Latex support is a god send, and I really appreciate the threading interface.

Distinguished Professor in Science

It is similar to Slack, but has a better user interface, and its compatibility with LaTeX makes it more friendly for scientific discussions.

Customer Desk

Excellent cost-effective solution for team collaboration.

What is currently missing is the easy voice chat that Discord or Slack provide.

My only complaint is that some features are available on Web but not on the Android app, for example linking to messages.

Team representative

Chat history, ease of use, folder/sub group system and the ability to share files.

Assistant Professor

For mobile you can only be signed in on one account at a time and it's a little annoying to switch.

My biggest issue is the lack of a scheduled message feature.

Zulip is a full on Slack replacement for a fraction of the cost. I really prefer the topic threading to the freeform nature of Slack as well.
