How to comment on someone's LinkedIn posts from your AI app

What has this person posted lately?

Start with the person. Give your AI app the link of their LinkedIn profile, or the name of someone it already found for you, and ask for their posts. It lists them newest first, 10 unless you ask for more. It only reads: nothing changes on your account or theirs.

• "What has this person posted on LinkedIn lately? Here is their profile link."
• "Show me the last five posts from the first person on yesterday's list."

• list_posts_by_authorList the posts one person or one company page published, newest first.

Each post comes with its text, its date, and how many reactions and comments it has. A company page works the same way: ask for the posts of the company instead.

Can I read what others already said under it?

Yes. Ask for the comments on a post before you write your own. Your AI app lists them, newest first, with who wrote each one. This also only reads.

• "What are people saying under her second post?"
• "Read me the comments on that post, so mine does not repeat them."

• list_post_commentsList the comments on one post, or the replies to one comment.

How do I leave the comment?

Point at one post and say what you want to write, or ask your AI app for a draft and change it until it sounds like you. When you say post it, the comment goes out on that one post, now, from your own account.

• "Draft a short comment on her latest post that adds one thing from our own work. Show it to me first."
• "Post that comment, as written."

• comment_on_postComment on one post, or answer one comment on it.

A comment can be up to 1250 characters. The answer says whether it went out, which of your accounts it ran on, and how many comments that account has left today.

Can I answer a comment, or comment as my company?

Yes to both. To answer one comment instead of the post, name the comment from the list above and your AI app replies under it. To write as a company page you run, say so and give the page.

• "Reply to the first comment under that post and thank them for the question."
• "Comment on this post as our company page, not as me."

If you have more than one LinkedIn account connected, say which one to use. Without that, the first live account is used.

How many comments can I post in a day?

Every kind of action here has a daily limit for each LinkedIn account. For comments on posts it is 40 a day. Ask how much of today's limits you have used at any time.

• "How many comments have I posted today, and what is the limit?"

• get_usageRead how many of each LinkedIn action your account used today, and each daily limit.

The full list of limits is on the actions page. The same two steps, list the posts and then comment, are also written out in the recipes.

Where to set it up

You ask in the AI app you already use. Connect it once, then ask in plain words as above. The setup for each app is on its own page: Claude, ChatGPT, Meta Muse, n8n, or the plain API.
