Can I remove someone from a ChatGPT group chat?

Yes. Open the group settings, go to People, select the member, and choose "Remove from group." The group creator cannot be removed.

Can a removed member rejoin the group?

If they still have the invite link, yes. After removing someone, reset or delete the invite link from the invite link modal (⋯ menu → Reset link) to prevent them from rejoining.

Is there a formal moderator or admin role in ChatGPT group chats?

No. ChatGPT does not currently have a dedicated moderator role with elevated permissions. The group creator and all members share access to most management tools, including removing members and sharing invite links.

Do personality presets affect the entire group?

Personality presets are account-level settings. They affect how ChatGPT responds to your messages specifically. Other members may have different presets, which means ChatGPT's tone can vary by participant. For consistent behavior across the entire group, use group-specific custom instructions.

Can I use apps or third-party integrations in group chats?

Not currently. Tasks, Apps, Agent mode, Canvas, Deep Research, and Python/Data Analysis are not available in group chats at launch. These features remain accessible in individual ChatGPT conversations depending on your plan.

What happens to my personal ChatGPT memory in a group chat?

Personal memory is automatically disabled once a chat has more than one member. Group chats do not read from or write to your personal memory. Your account-level custom instructions are also not shared in group chats.

How do I stop ChatGPT from responding to every message?

Switch to Mention-Only Mode in the group settings. In this mode, ChatGPT only responds when someone mentions @ChatGPT. This keeps the AI available on demand without it interjecting in human-to-human discussions.

What happens when a minor joins my group chat?

ChatGPT enters an under-18 mode with additional content protections that apply to all participants in the group, not just the minor. This may change the types of responses ChatGPT provides to everyone in the room.

Can everyone in the group see the custom instructions?

Group-specific custom instructions are accessible from the group settings and apply to the entire group. They are separate from your personal account-level custom instructions, which remain private.

How many people can be in a ChatGPT group chat?

ChatGPT group chats support between 1 and 20 people. Once the group reaches 20 members, new people cannot join until someone leaves or is removed.

Is ChatGroups affiliated with or owned by ChatGPT?

No. ChatGroups.com is an independent community directory and is not affiliated with, endorsed by, or owned by OpenAI or ChatGPT. It exists to help people discover, list, and join ChatGPT group chats organized by topic and interest.

How to Moderate a ChatGPT Group Chat

Creating a ChatGPT group chat is the easy part. Keeping it productive, focused, and enjoyable for every member is where moderation matters. Whether you are running a study group, a startup brainstorming room, or a creative community, you need to understand the tools ChatGPT gives you to manage participants, control how the AI behaves, and maintain the quality of conversation.

ChatGPT group chats support up to 20 people, and every member can see the full conversation history. That means moderation decisions — who stays, who goes, what ChatGPT does, and how the room is configured — have a direct impact on the experience for everyone.

This guide covers every moderation tool available: removing members, managing invite links, renaming your group, setting custom instructions, choosing ChatGPT participation modes, leveraging personality presets, understanding what features are and are not available in group chats, and applying safety best practices to keep your community running smoothly.

🛡️ Why Group Chat Moderation Matters

In a private one-on-one ChatGPT session, you control the entire experience. In a group chat, up to 20 people share the same conversation thread with AI. That dynamic changes everything. Off-topic messages, disruptive participants, or poorly configured AI behavior can derail the experience for the entire room.

Effective moderation is not about control for its own sake. It is about creating an environment where every member gets value from the conversation. A well-moderated group attracts and retains better participants, generates higher-quality discussions, and makes ChatGPT more useful for everyone involved.

ChatGPT does not have a formal "moderator" role with elevated permissions. Instead, moderation is a shared responsibility with a few key tools available to the group creator and all members. Understanding these tools and when to use them is the foundation of running a successful group.

👥 How to Remove People from Your Group

Removing a member is the most direct moderation action available. Use it when someone is disruptive, off-topic, or no longer a fit for the group's purpose.

🖥️ On Desktop / Web

Open the group chat at chatgpt.com.
Click the group chat name at the top of the conversation.
Select "People" to view the member list.
Click on the member you want to remove.
Select "Remove from group."

📱 On iOS / Android

Open the group chat in the ChatGPT app.
Tap the ✏️ pencil icon in the top-right corner of the screen.
View the member list under "People."
Tap on the member you want to remove.
Select "Remove from group."

⚠️ The group creator cannot be removed. If you created the group, you will always remain a member unless you choose to leave.

🔗 Managing Your Invite Link

Invite links are powerful — anyone who has the link can join your group. That makes link management a critical part of moderation. ChatGPT gives you two tools to control access:

🔄 Reset Link

Generates a brand-new invite link and immediately invalidates the previous one. Use this when your link has been shared beyond your intended audience, or after removing a disruptive member to prevent them from rejoining.

🗑️ Delete Link

Turns off joining by link entirely until you create a new one. The previous link is immediately invalidated. Use this when you want to temporarily close your group to new members or lock down the room during a focused session.

To access these options, open the invite link modal from your group settings and select the ⋯ menu.

💡 After removing someone from your group, consider resetting the invite link. Since anyone in the group can share the link, a removed member may still have access to the previous URL.

✏️ Renaming Your Group Chat

A clear, descriptive group name sets expectations for every member and helps keep conversations focused. You can rename your group at any time.

Open the group chat.
On Desktop: Click the group chat name at the top of the page.
On Mobile: Tap the ✏️ pencil icon in the top-right corner.
Tap the current name, enter the new name, and save.

A short system note will appear in the chat letting everyone know the name has changed.

💡 A well-chosen name like "Python Debugging Experts" or "Startup Pitch Feedback" communicates the group's purpose instantly. If your group's focus has evolved, rename it to match the current direction.

🤖 Controlling How ChatGPT Participates

One of the most impactful moderation decisions is controlling when and how ChatGPT responds in your group. ChatGPT offers two participation modes:

🟢 Automatic Responses (Default)

ChatGPT follows the flow of conversation and decides when to respond based on context. It generally replies when someone asks a question or requests help, but stays quiet during human-to-human exchanges that don't need its input. You can always mention "@ChatGPT" to get its attention.

🔕 Mention-Only Mode

ChatGPT responds only when someone explicitly mentions @ChatGPT in their message. It stays completely silent otherwise, even if questions are being asked. This mode is ideal when the group wants to have uninterrupted human discussion and bring in AI only when needed.

You can switch between these modes in the group's settings. Access them by clicking the group chat name (Desktop) or the pencil icon (Mobile).

💡 When to use Mention-Only Mode: If your group is primarily for human discussion (e.g., debate clubs, peer feedback, support groups) and you want ChatGPT available as an on-demand resource rather than an active participant, switch to mention-only. This keeps conversations natural while preserving access to AI when needed.

📝 Setting Group-Specific Custom Instructions

Custom instructions let you shape how ChatGPT behaves within a specific group chat. Unlike account-level custom instructions (which are private and not shared in group chats), group-specific instructions apply to everyone in the room and are visible to all members.

How to set custom instructions:

Open the group chat.
On Desktop: Click the group chat name → select "Customize ChatGPT" from the dropdown.
On Mobile: Tap the ✏️ pencil icon → select "Customize ChatGPT."
Enter your instructions and save.

What to include in custom instructions:

Personality and tone — e.g., "Keep responses concise and professional" or "Use a friendly, encouraging tone"
Group goals — e.g., "Help us plan our weekly study group" or "Focus on giving actionable startup feedback"
Behavioral preferences — e.g., "Summarize long links before responding" or "Always provide answers in a numbered list format"
Constraints — e.g., "Avoid using jargon" or "Respond only in Spanish" or "Do not provide medical advice"
Role assignment — e.g., "Act as a debate moderator" or "You are a creative writing coach for this group"

💡 Group custom instructions are a powerful moderation tool. They let you define what ChatGPT does and does not do in your room — effectively setting the AI's behavior policy for the entire group without relying on every member to prompt correctly.

🎭 Using ChatGPT Personality Presets

OpenAI offers built-in personality presets that change ChatGPT's base communication style. These are set at the account level (not per group), but they affect how ChatGPT responds across all your conversations, including group chats you participate in.

Available Personality Presets

Default — The standard, balanced ChatGPT: clear, neutral, and adaptable.
Professional — Polished, formal, and precise. Best for business communication, drafting documents, and workplace-appropriate language.
Friendly — Warm, conversational, and approachable. Good for casual discussions, decision support, and welcoming group environments.
Candid — Direct, honest, and action-oriented. Provides straightforward feedback with clear next steps, without unnecessary pleasantries.
Quirky — Creative, unconventional, and playful. Uses stories, metaphors, and humor. Ideal for creative brainstorming and casual communities.
Efficient — Concise and to the point. Minimal small talk, maximum information density. Great for technical groups and quick Q&A.
Nerdy — Exploratory, detail-oriented, and enthusiastic. Goes deep on topics with thorough explanations. Best for research and learning groups.
Cynical — Sarcastic, witty, and critically-minded. Challenges assumptions and offers a blunt perspective. Useful for debate groups or critical analysis.

How to Change Your Personality Preset

🖥️ Desktop: Click your profile icon → Settings → Personalization → Base style and tone dropdown.

📱 Mobile (iOS/Android): Open the menu → tap your profile picture → Personalization → select your preferred personality.

⚠️ Important: Personality presets are account-level settings, not group-level. They affect how ChatGPT responds to your messages across all conversations. In a group chat, ChatGPT's tone may vary depending on whose message it is responding to and their individual personality setting. For consistent AI behavior across the entire group, use group-specific custom instructions instead.

🎨 Combining Custom Instructions with Personality Presets

For maximum control over ChatGPT's behavior in your group, combine both tools strategically:

Custom instructions define what ChatGPT does — its role, constraints, response format, and group-specific rules. These apply to the entire group uniformly.

Personality presets define how ChatGPT communicates — its tone, style, and conversational approach. These vary per member.

Example configurations:

Study group: Custom instructions set to "Quiz us on key concepts, provide explanations when asked, and track what topics we have covered." Members might use the Nerdy preset for detailed explanations.
Startup feedback room: Custom instructions set to "Give direct, actionable feedback on business ideas. Point out weaknesses honestly." The Candid or Professional preset complements this well.
Creative writing community: Custom instructions set to "Help brainstorm story ideas, develop characters, and provide constructive writing critiques." The Quirky or Friendly preset adds personality.
Coding group: Custom instructions set to "Provide code examples in Python. Explain errors clearly. Suggest best practices." The Efficient preset keeps responses lean and technical.

💡 Custom instructions take precedence over personality presets when they conflict. If your group instructions say "respond formally" but a member uses the Quirky preset, the group instructions will generally win. This makes custom instructions the more reliable moderation lever.

🔒 Safety, Privacy, and Reporting

ChatGPT group chats include built-in safety systems, but moderators should understand how they work and what additional steps to take.

Built-in Safety Systems

Content screening — Images uploaded by users are screened to prevent sharing of illegal content (including CSAM) and to restrict sexually explicit imagery when minors are present.
Link checking — URLs shared in group chats are checked against trusted lists to reduce exposure to unsafe sites.
Teen safety — When a minor joins a group chat, ChatGPT automatically enters an under-18 mode with additional content protections. These protections apply to all participants while a minor is present.
Parental controls — Parents or guardians can link their account with a teen's account and can disable group chat entirely for the teen.

Reporting

Any member can report content or behavior:

In-product: Long-press or right-click a message to access reporting options.
Web form: Submit reports through OpenAI's official content report form.

OpenAI reviews reports and may take action in accordance with their usage policies.

Privacy Considerations

Conversation visibility: When a new participant joins, they can see the entire conversation history. Share sensitive information accordingly.
Files: Files shared in a group are visible to all members (including ChatGPT). Remove sensitive content you no longer want visible.
Training: OpenAI does not train on group chat conversations if any user in the group has disabled the "Improve the model for everyone" setting in their data controls.
Data export: Members can request an export of their data through ChatGPT's account settings or OpenAI's privacy portal.

📋 Moderation Best Practices

There is no single formula for moderating a group, but these practices consistently lead to healthier, more productive communities:

Set custom instructions early — Define ChatGPT's role, tone, and boundaries before inviting members. This sets the standard from the first message.
Choose a clear group name — A descriptive name like "UX Design Critique Circle" attracts the right members and discourages off-topic behavior.
Reset your invite link after removing someone — Prevent removed members from rejoining via the old link.
Use Mention-Only Mode for human-first discussions — When the group needs to talk without AI interruption, switch to mention-only so ChatGPT participates only when called upon.
Communicate expectations — Send an introductory message or pin a note (via custom instructions) outlining what the group is for, what behavior is expected, and how ChatGPT will be used.
Act on disruptions quickly — Remove disruptive members promptly. In a 20-person group, one bad actor can derail the experience for 19 others.
Review who can share the invite link — Remember that anyone in the group can share the invite link. If you need tighter control, delete the link after your desired members have joined.
Be mindful of minors — If a teen joins your group, ChatGPT's content protections will apply to the entire room. Plan your group's audience accordingly.
Leverage file and image capabilities — Share reference materials, project documents, or images that give ChatGPT (and members) better context for productive responses.
Iterate on custom instructions — As your group evolves, update the custom instructions to match. What worked at launch may need refinement as the community grows.
