Comments & mentions
Every thing has its own comments: a place to discuss it without touching its content. Mention a member to get their attention, or leave a job for the next AI agent that runs.
Open the comments
Open a thing and look at the row of round buttons at its top. The 💬 opens the comments below the thing's content and scrolls to them; press it again to hide them.
- A small badge on the 💬 counts the thing's comments, so you can see there is a discussion before you open it.
- A notification about a comment, a reply or a mention opens the thing with its comments already showing.
- In a read-only workspace the 💬 still appears when the thing has comments, so you can read them.
Write a comment
Comments work the same in every workspace, shared or not. In a workspace of your own they make a running log of thoughts about a thing.
- Open the thing and press 💬.
- Type in the box that reads Add a comment... (@ to mention someone).
- Press Add Comment. Your comment appears at once at the bottom of the list.
Dictate instead of typing
On the web, when your browser supports it, a mic sits in the corner of the comment box (Dictate) and turns speech into text at the cursor. Words still being heard show grayed out inside the box until they are added. Press the mic again (Stop dictation) to finish; Add Comment waits for the last words before it posts.
What a comment shows
Each comment shows its text, then a line with who wrote it and the date, such as By: Ann · Oct 17, 2026. A comment written through an agent or Slack adds where it came from (see below).
Plain text
Comments are plain text, kept exactly as you type them. Mentions are the exception: they show as a highlighted @Name.
Edit and delete
You can change or remove the comments you wrote, whatever your role. The workspace's owner and admins can also delete other people's comments, but nobody edits a comment but its author.
| Where | Edit | Delete |
|---|---|---|
| Web | The pencil at the top right of your comment opens it in a box. Change the text and press Save, or Cancel. | The trash icon beside the pencil deletes it right away. Admins see the trash icon on other people's comments too. |
| Phone | Edit on the web. | The trash icon on your comment deletes it. |
A comment an agent posted through your account counts as yours, so the same controls appear on it.
Replies
A reply answers one comment and sits under it. Replies are written in the phone app.
Reply on the phone
- Tap Reply on the comment you are answering. Replies go one level deep, so Reply appears on top-level comments only.
- The comment box shows Replying to (their name), and its hint changes to Write a reply... Tap Cancel to go back to a plain comment.
- Tap the send button. The reply appears indented under the comment.
Replies on the web
The web shows every comment on a thing in one list, oldest first, with replies in their place in time. The comment box on the web always starts a new top-level comment.
Who hears about a reply
The author of the comment you replied to gets a replied to your comment notification, and the thing's author gets the usual commented on one. A person who is both gets a single notification.
Mention a member
An @mention names someone in a comment and sends them a notification, so they know the comment is for them.
- Type
@in a comment box, at the start or after a space. A list opens with Agent and everyone else in the workspace (the owner and the members), by name. - Keep typing to narrow it:
@anfinds Ann and Dan. The list shows up to 8 matches, or No matching member. - Click a name, or move with
↑↓and pressEnterorTab.Esccloses the list and leaves what you typed as plain text.
How a mention looks
While you write, the box holds the mention as a code with the person's id, like @[Ann](user:…). Once posted, it reads as a highlighted @Ann on the web and on the phone, and as plain @Ann in notifications. An @ inside a word, like an email address, never opens the list.
What the mentioned person gets
A notification that reads “(your name) mentioned you on (thing)”, with the start of the comment. It replaces the comment or reply notification they would otherwise get for the same comment, so nobody hears twice. Each person can turn mentions off per workspace with Mentions of me; see Notifications.
Mentions work on the web and on the phone. You can't mention yourself, and only people in the workspace appear in the list.
Leave a job for @Agent
Agent heads the @ list on every account. Picking it turns a comment into a job for whichever AI agent runs next in the workspace.
- Write the request with @Agent in it, for example “@Agent please break this thing up into sub-things”, and post it.
- Nobody is notified. The comment waits as an open job.
- The next agent run with access to the workspace finds it (the
list_mentionstool), reads the thing and does the work. - The agent closes the job with
resolve_mention: your @Agent turns into 🤖agent, and the agent posts a reply under your comment saying what it did. That reply reaches you as a replied to your comment notification.
The Everythings server tells every agent to look for @Agent jobs right after it checks what changed. When a job is unclear, the agent asks you a question on that thing and leaves the job open until it is done. The Claude Code plugin counts open jobs above the prompt. The agent's side, and the questions agents ask you: Questions, inbox & @Agent.
Comments from agents and Slack
A comment always belongs to a person. When it reached Everythings through something other than the app, the author line says so with via.
| Written through | Author line reads | Notes |
|---|---|---|
| An AI agent | By: Ann · via Claude | The agent used Ann's account. Notifications about it name the agent. |
| The Claude Code pane | By: Ann · via the agent's name | The pane posts through the agent's connection, so the comment carries the agent's label even though Ann typed it. |
| A Slack card | By: Ann · via Slack | Ann pressed Comment on a card in Slack. It counts as her own comment. See Slack. |
Limits
Comments are open on every plan. A few caps keep the numbers sane.
| Limit | Free | Plus |
|---|---|---|
| Comments on one thing (by the workspace owner's plan) | 100 | 1,000 |
| Comments one person posts per day (by their own plan) | 300 | 2,000 |
| Length of one comment | 10,000 characters | 10,000 characters |
A thing at its comment cap refuses new comments and says why; on Free the message offers Plus. In a workspace that is locked to read-only, the comment box is replaced by “This workspace is read-only, so new comments are closed.” See Plans & limits.
Questions
Can I format a comment with Markdown?
Comments are plain text: what you type shows as written. Mentions are the one thing drawn differently. For formatted writing, put it in the thing's content, or in a sub-thing.
Can I delete someone else's comment?
Only if you are an admin or the owner of the workspace: they can delete anyone's comment, though not edit it. Editing stays with the person who wrote the comment. A comment your own agent posted through your account counts as yours, so you can edit or delete it.
Why isn't the person I want in the @ list?
The picker lists the owner and members of the thing's workspace, minus you. Someone with a pending invitation shows up once they accept. For someone outside the workspace, invite them first; see Sharing a workspace.
I added a mention when editing a comment. Was the person told?
No. Mention notifications go out when a comment is posted. To make sure someone hears about it, post a new comment that mentions them.
Who picks up an @Agent job in a shared workspace?
The first agent run that reaches it, from any member's connected agent. Once it resolves the job, your @Agent reads 🤖agent and the job no longer lists, so each one is done once. See Questions, inbox & @Agent.
Do comments go to Trash with their thing?
Yes. A thing in Trash keeps its comments, and restoring the thing brings them back with it. Emptying Trash deletes them for good. See Things.
