Messages are the basic building blocks of channels and direct messages. Threads keep a focused reply chain beside one
message, so the main conversation stays readable.
Send a message
Type in the message box and press Enter to send. Press Shift + Enter for a new line.
You can add files, images, links, and emoji. In a channel, type @ to mention a teammate, AI model, or agent. In a
direct message, mentions and notifications focus on the person you are messaging.
Start a thread
Open the message actions and choose Reply in thread. Use a thread when:
- you are answering one question from a busy channel;
- several people need to work through a detail;
- an AI answer needs review without taking over the main conversation.
People who take part in the thread can return from their notifications. Mention someone if their input is needed.
Use message actions
Open the actions on a message to find options available to you. Depending on the conversation and your access, you can:
- react with an emoji;
- reply in a thread;
- copy the message or its link;
- edit or delete your own message;
- turn the content into a canvas;
- use an action from a connected app, such as creating or linking a Linear issue.
Write messages people can act on
A useful team message says what changed, why it matters, and what should happen next. For example:
The onboarding copy is ready for review. Please check the three screens linked below by Thursday. Mina owns the final
decision; use this thread for comments.
Use a reaction for quick acknowledgement. Use a reply when you need to add information or make a decision.
Edit and delete carefully
Edit small mistakes freely. If an edit changes a decision or request after others have replied, add a note explaining
what changed. Delete messages only when the content should no longer be part of the conversation record.
If a thread produces a lasting plan, turn the key message into a canvas and link it back in the channel.
