A thorough comparison of the two major business chat apps! Which tool is right for you?

In business, efficiency is a big issue. In a workplace where conventional emails and telephones are the main internal tools, it is not possible to say that work efficiency is good when replying to each person is included.

Therefore, in order to facilitate communication within the company, more and more attention is being paid to chat applications that do not have unnecessary introductions and have quick responses.
A chat app is a messenger app that allows you to easily attach messages and files . You can send messages in a conversational tone like LINE, and you can share real-time information with all participating members, so if someone posts, all members can grasp the data and information.
Also, when you reply to the post, you can communicate with all the members, so you can get in touch quickly.

This time, for those who are thinking about introducing a chat app, I would like to introduce the features and benefits of the two major vendors + other apps, how to actually use them, and the points to note when introducing them! Also, at the end of the article, we will be presenting a “‘Chatbot Vendor’ Thorough Comparison Collection”, so please stay tuned!

Effects of introducing chat apps

When using a chat app, you may be wondering what kind of efficiency you can achieve and how you can reduce costs. Next, we will compare the operations and costs before and after the introduction of the chat application.


Before the introduction of the chat app, in a workplace where e-mail and phone were the main means of communication, it would be a repetition of sending and receiving e-mails, checking the reply of each person in charge, and replying to it again. Even if you can send it all at once using CC, if you are not in charge, opening the email will feel troublesome, and the read rate will be low, which can be said to be a lack of communication within the company.
By introducing a chat app, you can share real-time information about one agenda or issue, and it will be easier to reflect the opinions of members, so communication will spread more easily and decision-making speed will increase. You can manage tasks on the chat app, such as creating proposals and meeting minutes, and you can prevent forgetting to do or forget to tell. In addition, you can prevent the original work from being interrupted by answering the phone.
In terms of cost, you can reduce the time required for meetings, answering phone calls, and exchanging emails. By introducing a chat app, you can concentrate on the work you are supposed to do, which will lead to a reduction in overtime work.


On the other hand, chat apps also have their drawbacks. Many elderly people feel that face-to-face communication will disappear as chat becomes more convenient. The introduction of chat apps may create a gap in perception between generations, and it is possible that communication will deteriorate.
Also, the fact that you can easily post and share information means that there is a large amount of information, so it is possible that you may overlook important information and have a hard time finding it later. In addition, since multiple members can participate, important materials and data, including a large amount of information, are shared on the chat, so it is necessary to take thorough security measures such as appropriately dividing authority.

A thorough comparison of the two major vendors: Chatwork

Chatwork was founded in Japan in 2000 and provides business chat apps. It has been introduced by 200,000 companies by 2018, and has a rich track record of introduction in domestic companies, from sole proprietors to major companies.

Features of Chatwork

Here’s what you can do with Chatwork.

・Group chat that can be linked with people outside the company
Multiple people can participate at once and share messages and files. Chat can be developed for each project or between departments, and it is possible to have fun chatting with a full range of functions such as LINE’s stamp function and emoticons for emails. Since there is a reply function, it is easy to check whether it is a reply to a unique message. In addition, you can keep in touch with people outside the company, so if you have a lot of contact by e-mail, you will need a formal message every time, but with Chatwork, you can easily do it with just one word.

・Task function
When chatting between projects or departments, tasks (things to be done) may occur in the process. For example, you can manage tasks such as project proposals and meeting minutes by deciding the person in charge and submission deadline. If you create tasks that you don’t want to forget, you can say that it is possible to share common recognition among members. Other members will be notified when the task is completed.

・Video / voice call function
Chatwork has video call and voice call functions. There are times when there are many characters with just a chat function that just type characters, and there are cases where it is difficult to convey to the other party. In such cases, it is very convenient to be able to talk immediately on Chatwork rather than switching to phone or Skype. In addition, since it is possible to make a video call with multiple people, it is possible to hold a video conference even if it is far away.

Fee structure

There is a free plan, but with limited functionality.
Chatwork has plans of 0 yen, 400 yen, 500 yen, and 800 yen every month, and the business type 500 yen plan is 417 yen for an annual contract, which is a good price for 2 months.

An in-depth comparison of two major vendors: Slack

Slack was developed in the United States in 2013 and focused on communication tools between engineers. After its official release in 2014, it quickly gained popularity, boasting 6 million users by 2018.

Features of Slack

Here’s what you can do with Slack.

・Collaboration with 300 types of external services
Slack can cooperate with external services that are familiar to the general public, such as Google, Facebook, and Twitter. There are 300 types of such devices, and it is possible to share data and files, link video chat tools, and share location information functions.

To explain with a simple example, if you register the date and time of important meetings and meetings in Google’s calendar function, you will be able to receive notifications on Slack. Slack can be expected to improve work efficiency by linking with external services and applications.


・Snippet is for functional engineers who share the programming language
, but when you type in the programming language and select the code, the code is colored and the indentation is automatically displayed. This makes it easier to see and easier to communicate when communicating with other engineers.

・ Advanced search function
Slack can search for all messages posted to the channel, making it easy to find out what kind of process the search content has been in when you want to check past cases.

・Japanese language support
Since Slack originated in the United States, it has not been fully supported in Japanese so far. However, in November 2017, it became compatible with Japanese localization. In response to this, even if the chat tool is divided between projects or departments, it is possible to unify it with Slack within the company.

Fee structure

There is a free plan with limited functionality.
Slack consists of three monthly plans: 0 yen, 850 yen, and 1600 yen. 850 yen and 1600 yen are monthly payments for annual payments. If you compare only the fees, Chatwork feels cheaper, so if you run it with a small number of members, Chatwork can be said to be more profitable.

A Thorough Comparison of Two Major Vendors: Judgment Criteria

The question is whether to use Chatwork or Slack, but this depends on the work content of the user. Chatwork is a service that was born in Japan, so it is extremely easy to use, but Slack has many external service linkages, and the number of users is increasing all over the world. It would be better to compare the features of each chat app with your own work content.
For example,
Chatwork, which has many task management functions and domestic users,

・If your business partners are mainly domestic companies and you want to communicate well with external people・
If there are many tasks that you decide the deadline for those who do the tasks yourself and those who request it
・When you introduce a chat application for the purpose of reliably completing one project .

On the other hand, Slack, which is aimed at developers and is easy to link with overseas services,

・If you are an IT-related person such as an engineer or growth hacker
・If you use many external services that can be linked

It can be said that it is suitable for

Compare 3 Chat Apps You May Be Missing

We’ve covered two of the biggest chat apps, but there are others that you might be missing. Next, let’s take a look at three representative chat apps.

Microsoft Teams

It is a chat application provided by Microsoft. Not only online meetings with message functions and video calls, but also project management, file sharing and collaborative editing are possible. You can use office applications such as word and excel, and you can share files in advance of the project, so you can communicate smoothly from the planning stage. There are three plans, and the annual plan consists of 540 yen, 900 yen, and 1360 yen per month.

Google Hangouts Chat (G suite)

A chat service provided by Google. It integrates with many of Google’s favorite features such as Gmail, Sheets, Docs and Calendar. It is possible to open a chat room and manage projects on a project-by-project basis, and it also features 24-hour support via email and phone. There are three plans, consisting of 600 yen, 1200 yen, and 3000 yen (only 600 yen is an annual contract and the monthly fee is 500 yen).


Business chat tools improve work efficiency by promoting communication, but when chatting with multiple members, the conversation may deviate from the point of discussion. Therefore, ONETEAM has a concept (topic) that solves business problems, not as a communication tool.
By creating this topic and adding comments directly to it, an attitude of solving problems with a common awareness will be born. There are four plans, and the monthly fee for the annual plan changes depending on the number of team users, 4950 yen (5 to 10 people), 11700 yen (11 to 20 people), 17550 yen (21 to 30 people). There is a separate charge system for 31 or more people.

Business chat is even more advanced in cooperation with “chatbot”!

Various business chats can link each account with a chatbot.

For example, by using a chatbot as the help desk for the general affairs, human resources, and information systems, it will be possible to automatically respond to most of the questions received from the photos. As a result, the number of employees that must be devoted to responding to inquiries can be significantly reduced.
