A group chat is a conversation between three or more people in a single message thread
A group chat is a messaging space where multiple people can send and receive messages together in one place, rather than having separate one-on-one conversations. Everyone in the group sees the same messages in the same order. When one person sends a message, all the others in that group see it when ready (or within seconds, depending on internet speed).
Group chats exist in most messaging apps you probably already use: text messaging on your phone, Facebook Messenger, WhatsApp, Slack, Discord, iMessage, or Teams. The basic idea is the same across all of them — you add multiple people to a single conversation thread instead of texting each person individually.
The main difference between a group chat and texting one person is that everyone can see what everyone else wrote. There is no private side conversation happening. If you send a message in a group chat, all members see it. If someone else replies, you see that too.
Key Takeaways
- A group chat lets three or more people message in one thread where everyone sees the same conversation.
- Group chats work in apps you already have, like text messaging, WhatsApp, Facebook Messenger, Slack, or iMessage.
- Everyone in the group sees every message sent, so there are no private side conversations within the group.
- You can add or remove people from a group chat, and the group can have a name so members know what it is for.
- Group chats are useful for coordinating plans, sharing updates with multiple people at once, or keeping a team or family connected.
How to start a group chat
The exact steps depend on which app you use, but the basic process is the same. In most messaging apps, you look for a button or option that says "New Chat," "New Message," "Create Group," or a plus sign. You then select the names of the people you want to include. Some apps let you name the group right away; others let you add a name later.
On an iPhone using iMessage, you tap the pencil icon to start a new message, then add multiple contacts. On Android using standard text messaging, you open the messaging app, tap the compose button, and add multiple phone numbers. In WhatsApp, you tap the chat icon, then "New Group," and select the people you want. In Slack, you create a channel and invite team members to it.
Once you send the first message, the group chat is created. Everyone you added will see the conversation and can start messaging back. If you want to add someone later, most apps let you do that without deleting the chat — the new person just sees messages sent after they joined.
The difference between group chats and channels
In workplace apps like Slack or Teams, you might hear the term channel instead of group chat. A channel works similarly — multiple people in one conversation thread — but channels are usually organized by topic or team rather than by a specific group of friends or family.
A channel in Slack might be called #marketing or #random, and anyone in the company can join it. A group chat is usually smaller and more private — you add specific people you know. But the actual experience of reading and sending messages is nearly identical.
Some apps blur this line. Facebook Messenger has both group chats (which you create with specific people) and group pages (which are more public). WhatsApp has only group chats. Slack has only channels. The names and rules differ, but they all serve the same basic purpose: letting multiple people message together in one place.
What happens when someone leaves or is removed
If someone leaves a group chat, they stop receiving new messages. They can usually still see the messages that were sent before they left, but they will not see anything sent after. If you remove someone from a group chat, the same thing happens — they are out of the conversation going forward.
In most apps, the group chat continues without them. Other members keep messaging. Some apps notify the remaining members that someone left or was removed; others do not. If you want to add that person back later, you can usually do so, and they will see the messages from after they rejoin, but not the ones they missed while they were gone.
Notifications and muting group chats
Group chats can send a lot of notifications, especially if many people are messaging at once. Most apps let you control how many notifications you get. You can usually mute a group chat so you do not get a sound or vibration every time someone sends a message, but you can still read the messages when you open the app.
Some apps let you mute notifications for a set amount of time — like one hour or eight hours — and then turn them back on automatically. Others let you mute a chat permanently until you unmute it. You can also usually change the notification sound or turn off notifications entirely for a specific group chat while keeping notifications on for other chats.
Muting a chat does not remove you from it. You are still a member and can still send and read messages. You just will not get pinged every time someone writes something.
Common uses for group chats
People use group chats for many different reasons. A family might have a group chat to share photos, plan holidays, or keep everyone updated on what is happening. A friend group might use one to coordinate weekend plans or share jokes and memes. A sports team might use a group chat to discuss games or arrange practice times.
At work, group chats (or channels in apps like Slack) help teams stay connected without needing a formal meeting. A project team might use one to ask quick questions, share files, or give updates. A company might have a general channel where anyone can post announcements or celebrate wins.
The key advantage is that you can reach multiple people at once without sending the same message over and over. Everyone sees the same information, so there is less chance of someone being left out or getting confused about what was decided.
Privacy and what others can see
In a group chat, every member can see every message that every other member sends. There is no way to send a private message to one person within the group chat itself — if you want to say something only one person should see, you need to start a separate one-on-one chat with them.
Some apps let you control who can see the group chat. In Slack, a channel can be public (anyone in the company can join and see all messages) or private (only invited members can see it). In WhatsApp, group chats are private by default — only people you add can see them. In standard text messaging, group chats are usually private to the people in them.
If you take a screenshot of a group chat or forward a message to someone outside the group, they can see what was said. The app itself does not prevent this, so be mindful of what you write. If something is sensitive, a group chat may not be the right place for it.
Frequently Asked Questions
Can I see messages from before I joined a group chat?
It depends on the app and when you joined. In most cases, you can see messages sent after you were added, but not messages from before. Some apps let the group owner decide whether new members can see the full history. If you need to catch up, ask someone in the group to fill you in or share screenshots of earlier messages.
What is the difference between a group chat and a group text?
These terms are usually used interchangeably. A group text typically refers to a group chat sent through standard text messaging (SMS) on your phone. A group chat is the broader term that includes text messaging, WhatsApp, Facebook Messenger, and other apps. The function is the same — multiple people in one conversation.
Can I delete a group chat without removing everyone else?
Yes. Deleting a group chat from your phone or app only removes it from your own view. Everyone else in the group can still see it and message in it. If you want to actually end the group chat so no one can message in it anymore, you usually need to be the group owner or administrator, and the option may not exist in all apps.
How many people can be in a group chat?
Most apps support group chats with dozens or even hundreds of people, though the exact limit varies. In standard text messaging, some phones cap out around 20 people. In WhatsApp, you can add up to 256 people. In Slack, channels can have thousands of members. Check your specific app if you need to add a large number of people.
Do group chats use data or just text messages?
It depends on the app. Standard text messaging (SMS) uses your phone plan's text message allowance. Apps like WhatsApp, Facebook Messenger, Slack, and iMessage use internet data instead. If you are on Wi-Fi, they use your Wi-Fi connection. If you are on mobile data, they use your data plan. Check your app to see which one you are using.
