An internal note is a message in a conversation that only your team sees. Line never sends it to the customer. You can mention a teammate in a note, and the conversation then shows in their **Mentions** view.

## Add an internal note

1. Open the conversation in the **Inbox**.
2. In the composer, select the **Internal note** tab.
3. Type the note.
4. Select **Add note**.

The note shows in the thread with a different colour. It stays in the conversation on every channel and in every view.

> **Note:** Check the tab before you type. The **Reply** tab sends the message to the customer.

## Attach files to a note

You can attach files to a note on every channel, including SMS.

1. Select the **Internal note** tab.
2. Select **Attach a file**, or drop a file on the thread.
3. Select **Add note**.

A note can hold up to 5 files of up to 25 MB each. A note can hold only files, with no text.

## Mention a teammate

1. In the **Internal note** tab, type `@`.
2. Select the teammate from the list.
3. Finish the note and select **Add note**.

The teammate sees the conversation in **Mentions** in the Inbox sub-menu.

## See your mentions

1. Open **Inbox**.
2. Select **Mentions** in the sub-menu.

**Mentions** lists the conversations in which a teammate mentioned you. It also shows your mentions from team chat.

## Discuss a note in team chat

Each note has a **Discuss in chat** button. It starts a team chat discussion with the conversation and the note text. The note then shows the number of replies. See [Chat with your team](https://useline.io/help/inbox/team-chat).
