You ask your AI client for the comments on your posts, deal with them, and tell it when you are done. This page says what you can ask for on Facebook, Instagram and LinkedIn, what each needs, and what is refused.
Ask for the new comments of a Facebook Page, an Instagram account or a LinkedIn Page. The server looks at the most recent posts (10 unless you ask for more, up to 25) and returns the comments that arrived since you last marked them seen, oldest first under each post. On a post you have never marked, every comment is new.
You can also ask for all the comments on one post, newest first, with their replies.
A few things differ by platform:
Facebook
Instagram
LinkedIn
Who wrote it
Often not shown: Meta gives the name only when that person authorised the app
The username
An id only: LinkedIn gives the app no other member's name

If one post has more new comments than a single read covers, the answer says so and tells the AI client how to go through that post.
Reading marks nothing. After you have dealt with the comments, ask the AI client to mark them seen:
Those are handled. Mark them as seen.
The next time you ask, you get only what arrived after them. This order is deliberate: if a session stops halfway, no comment is lost, because nothing was marked until you said so.
The mark is the server's own note of how far you have read, kept for you alone. It changes nothing on the platform, it never moves backwards, and it needs no write access.
Reply to the first comment: "Thank you! We open at 9 every day."
A reply is public and goes live at once. There is no draft for a comment. So the AI client shows you the comment and the proposed reply first, and sends it only after you confirm. This happens for each reply. See How it keeps you safe.
The preview is the server's own check. The platform has not seen the reply at that point and may still reject it.
Replies are one level deep on Instagram and LinkedIn: to answer a reply, you answer the comment it is under. Instagram does not allow a reply to a hidden comment. A LinkedIn reply is sent as plain text and cannot mention anyone.
Replies have their own cap, separate from the cap on posts, so a busy day of answering comments never uses up the day's posts. The administrator sets it on Safety limits, under Posting limits:
Label
Starts at
Comment replies per person per day (Facebook and Instagram together)
50
Longest reply, characters
1000
LinkedIn comment replies per person per day
50
Longest LinkedIn reply, characters
1250
The count is per person over the last 24 hours. An empty box means no limit. A reply over a limit is refused, and the refusal says so.
Hiding works on Facebook and Instagram. A hidden comment stays visible to the person who wrote it and their friends, and you can bring it back at any time:
Unhide the comment we hid yesterday.
Because it can be undone, hiding is the way to deal with a bad comment. Up to 50 comments can be hidden in one request. Instagram always shows the account's own comments, so those cannot be hidden.
On Instagram you can also turn comments off for one post, and on again later. Turning them off hides and deletes nothing that is already there.
LinkedIn has no hide
LinkedIn cannot hide a comment, and nothing here deletes a LinkedIn comment or closes a thread. On LinkedIn you answer a comment or you leave it.
Deleting a comment cannot be undone, and its replies go with it. It is off by default:
The administrator opens Meta app and, under Comments and moderation, ticks Allow deleting comments.
Until then every delete is refused, and the refusal suggests hiding instead.
With the switch on, a delete works on Facebook and Instagram, one comment per request, and it asks twice: you see the comment first, then confirm that you want it deleted. The comment as it was is kept in the activity log.
An ad's comments are the comments on the post the ad shows. That post is often on no timeline, so it is not among your recent posts.
Show me the new comments on our posts and on the ads running from our ad account.
What are people commenting on the ads in ad account 123456789?
You reply to, hide and delete these comments the same way as any other, under the same cap and the same switches. Reading the comments on ads needs Meta Ads switched on: see Meta Ads.
On Facebook, reading comments works from the start. The rest needs more permissions, which are off by default.
Meta, on Meta app under Comments and moderation:
Ask for the comment permissions when people connect adds two permissions to the Meta sign-in. They are needed to read Instagram comments, and to reply to or hide comments on Facebook and Instagram.
Meta grants these through App Review (Advanced Access) for anyone who has no role on the app. Asking for a permission that the app does not have makes signing in fail for everyone, so leave the switch off until Meta has approved them.
After it is switched on, everyone already connected reconnects on Meta connection to grant them.
LinkedIn, on LinkedIn app under Comments:
Reading comments and replying may already work with the permissions that people grant for posting. If a reply is refused for a missing permission, and the app has LinkedIn's Community Management API, the administrator ticks Ask for the Community Management comment permissions when people connect.
LinkedIn refuses the whole sign-in for a permission the app was not approved for, so leave it off until LinkedIn has approved the app. Afterwards everyone reconnects on LinkedIn connection.
How far you have read each post: a post id and a time.
An activity log row for every reply, hide and delete. On Facebook and Instagram, the row of a reply or a delete includes the comment it was about. On LinkedIn the row holds ids only, never the commenter's name or words, because LinkedIn's terms limit what may be kept.
The server does not judge what a comment says. An alert rule can tell you when the number of comments jumps, and you then read them: see Budgets and alerts.
Comments
You ask your AI client for the comments on your posts, deal with them, and tell it when you are done. This page says what you can ask for on Facebook, Instagram and LinkedIn, what each needs, and what is refused.
What you can ask
Reading new comments
Ask for the new comments of a Facebook Page, an Instagram account or a LinkedIn Page. The server looks at the most recent posts (10 unless you ask for more, up to 25) and returns the comments that arrived since you last marked them seen, oldest first under each post. On a post you have never marked, every comment is new.
You can also ask for all the comments on one post, newest first, with their replies.

Replying needs write access on your account here.
The daily cap on replies
Replies have their own cap, separate from the cap on posts, so a busy day of answering comments never uses up the day's posts. The administrator sets it on Safety limits, under Posting limits:
