# Comments

> Comment on a shared document, reply in threads, and mark as resolved

Comments help teams collaborate while writing the document and let recipients exchange directly on the document content without back-and-forth emails.

## Who can comment

* Organisation members can comment as long as the document is not locked.
* Guests can comment, unless the sender disables it for that share — see [Guest access](/features/sharing/sending-options#guest-access).
* Anonymous readers (access via public link) can read the document but **cannot comment**.

<Note>
  Automatic locking disables comments when the configured delay expires. [Configure locking](/features/sharing/sending-options#automatic-lock)
</Note>

## Create a comment

1. Open the shared document.
2. Select text / several blocks, or open a block menu from the handle.
3. Click **Add comment**.
4. Write the message, then send it.

To leave a global comment, open the **Comments** panel and add a comment without selecting a passage.

<Tip>
  To comment on a task, use **Add comment** from the block menu.
</Tip>

## Threads

Each comment opens a discussion thread:

* Participants can reply directly in the thread.
* Organisation members can be mentioned with `@`.
* Once a topic is addressed, the thread can be marked as **resolved**.

## Notifications

Each new comment or reply in a thread triggers an email notification to all participants in that thread. An organisation member mentioned with `@` also receives a dedicated notification. Comment actions are also visible in [read tracking](/features/sharing/read-tracking).
