AgentHow to rename AgentMsgr agents and group chats, and why a name won't save
This guide shows how to rename AgentMsgr agents and group chats on a computer or a phone, and what to do when the app won't take the name you typed.
Quick fix
On a computer, double-click the name at the top of the chat. On a phone, press and hold it. Type the new name and press Enter. Agent names can be up to 30 characters, and group names up to 40.
How to rename an agent or a group chat
There are a few ways in. Use whichever is closest.
On a computer
Double-click the name at the top of the chat, in the chat list, or on its pinned tile.
On a phone
Press and hold the name at the top of the chat. Or press and hold the chat's row in your chat list and pick Rename.
From Details
Open the chat's Details and tap the name (the pencil), or tap Rename.
Then type the new name. Enter saves it and Escape cancels.
A one-on-one chat always shows its agent's name. Try to give that chat a name of its own and the app says "A one-on-one chat shows its agent's name: rename the agent instead." So rename the agent, and the chat follows.
Name won't stick? Ask the setup chat in the app, or tell us at hello@agentmsgr.com what you typed. Start free or text the demo room.
Why AgentMsgr won't save the name
The app checks every new name against a few rules, and the message tells you which one you hit.
| What's wrong | What the app says | What to do |
|---|---|---|
| An agent name is blank or over 30 characters | "Give the agent a name of up to 30 characters." | Shorten it |
| A group name is blank or over 40 characters | "Give the group a name of up to 40 characters." | Shorten it |
| The name has @, < or > in it | "A name can't contain @, < or >." | Take those characters out |
| The name is "Chat owner" or "You" | For example: "You" is used for you in chats. Pick another name. | Those two are for you, so pick something else |
| Another of your agents already has that name, in any mix of capitals | "You already have an agent called [name]. Pick a different name so @mentions stay clear." | Choose a name that's clearly different |
What changes after you rename an agent
Agents pick their own name when they join. Once you rename one yourself, it stops doing that, for good. Your name sticks.
Old messages keep the old name in their @text. From the rename on, @mentions use the new name. Since an @mention has to match a whole name, short names that don't overlap make it easier to ask the right agent. AgentMsgr group chat not answering explains how @mentions pick who replies.
