LinkedIn Bans the AI Extension Even When You Click Comment Yourself

LinkedIn judges a tool by what it does on linkedin.com, whoever presses the button. Two tests sort every AI tool you use.

Picture a browser extension that adds a small "Draft reply" button under every post in your LinkedIn feed. You click it, read the draft, fix a word and press Comment yourself. Under LinkedIn's written rules that extension is banned, and your click doesn't save it.

ChatGPT in another tab, pasted into LinkedIn by hand, is fine. This is one of four deep dives behind my essay on LinkedIn's AI slop crackdown.

In short

  • A browser extension that reads your LinkedIn feed or adds buttons to it is banned, even if you click Comment yourself.
  • ChatGPT in its own tab, pasted in by hand, breaks no LinkedIn rule.
  • LinkedIn publishes no approved tool list and no safe daily limit. A tool that still works hasn't been stopped yet.
  • A customer story your AI invented breaks LinkedIn's policies. A missing "written with AI" label on text breaks none I could find.

LinkedIn bans any tool that runs on its site, whoever clicks

On February 13, 2026, Gyanda Sachdeva, LinkedIn's VP of Product Management, defined automated comments as those "submitted to LinkedIn via a browser extension, script, or third party tool, without human action involved in clicking the 'comment' button." They are not allowed.11 Her video added a line many people read as a permission slip.

“We welcome tools that help you engage on LinkedIn thoughtfully and responsibly, but we do not allow tools that bypass human review entirely and post automated content on your behalf.”

Two other lines in LinkedIn's rules say more:

  • The User Agreement bans tools that "Overlay or otherwise modify the Services or their appearance (such as by inserting elements into the Services...)."48
  • The Help Center bans "third-party software or browser extensions that scrape, modify the appearance of, or automate activity on LinkedIn's website."15

Neither asks who clicks, so a tool has two tests to pass. A person reviews and submits the content, and the tool stays off LinkedIn's pages.

The "Draft reply" button passes the first test and fails the second. It read the post off your screen and drew a button into LinkedIn's page before you clicked anything. Your approval answers the first test and leaves the second untouched. LinkedIn hasn't ruled on this exact case, so this is my reading, and I'd stake my own account on it.

No tool comes with a safe daily limit

LinkedIn's rules name no products and list no approved vendors. Its prohibited-software page covers bots, plug-ins and extensions, and warns they "may become non-operational without notice."14 On pace, it says only that it "may limit how many comments a member" can make, and gives no number.6 A tool that advertises safe daily limits is selling a number LinkedIn never wrote down.

Sort your tools by where they run

  • A chatbot in its own tab. You paste in and copy out. Nothing touches LinkedIn, so it passes both tests.
  • A comment helper in your feed. If it reads the post on your screen and puts a button or draft under it, it fails however carefully you review.
  • A grammar extension that underlines text in LinkedIn's composer. The underline is an inserted element, and LinkedIn hasn't addressed spell-checkers. I'd switch it off on linkedin.com.
  • A scheduler on its own website. LinkedIn lists no posting tools it trusts, so you rely on something unwritten.
  • Anything that comments, likes, shares or connects for you. The User Agreement bans "bots or other unauthorized automated methods" for exactly those actions.48

Handful sits outside your account. It never logs in or touches it, and you post every comment yourself.

Is pasting a post into ChatGPT scraping? LinkedIn hasn't said, and I don't read it that way, since the scraping clauses target software. The contract does ban using content "obtained from the Services" without the owner's consent.48 So paste only the post you're answering, never a DM, and never republish a model's rewrite of someone else's post.

Save this

Before you let an AI tool near your LinkedIn

  1. Does any part of it run on linkedin.com? Then clicking Comment yourself doesn't make it allowed.
  2. Does it read your feed or add buttons and drafts to LinkedIn's pages? Banned, however carefully you review.
  3. Does it like, comment, share or connect for you? Banned outright.
  4. Grammar extension underlining text inside LinkedIn? Turn it off on linkedin.com.
  5. "It still works" proves nothing. LinkedIn publishes no approved list and no safe daily limit.
  6. A chatbot in its own tab, pasted in and out by hand, breaks no rule.

LinkedIn catches hundreds of thousands of automated comment attempts a day

On July 30, 2026, Chief Product Officer Hari Srinivasan wrote that LinkedIn is "catching hundreds of thousands of automated comment attempts" every day and had "blocked billions of other automation attempts (posting at scale, slop)" in the previous couple of months.10

A detected automated comment drops out of "Most relevant," the default view under a post, and is sometimes hidden outside the commenter's network. Repeat offenders may have their access restricted.11 The first two penalties only change who sees the comment, so the person using the tool may never notice. If an account is restricted for automated activity, LinkedIn says to disable the tool, and the account is re-enabled "at the time specified on the suspension notification."15

This enforcement targets automation. Whether AI helped write the words is a separate question, and Srinivasan wrote that "AI and slop are not the same thing."10

LinkedIn's own AI writer now only proofreads

The Help page for LinkedIn's AI-powered post writer now says that tool "is not available at this time."47 Its replacement, Post proofreader, fixes spelling and grammar, shortens and clarifies, and shows each change inline. "Changes aren't applied until you accept them." For now it is English only, for Premium Career and Business subscribers.46 That is a fair model for any AI near your LinkedIn: it edits what you wrote, and you accept each change.

Invented experience is banned, and an AI label is optional

The one thing a model can't do for you is lend you a past. The policies ban "misleading or deceptive information about yourself, your business, your qualifications, work experience, affiliations, or achievements."7 A customer story the model made up is exactly that, with your name on it.

Labels are looser. You may not share synthetic media "that depicts a person saying something they did not say or doing something they did not do" without clearly disclosing it.7 For text, LinkedIn only recommends that you "let others know (if it isn't obvious from the context) if you've relied heavily on AI."1 No rule I found restricts an account over a missing label. If you brought the point and the model tidied the sentences, the post is yours and I wouldn't footnote it.

The safe setup runs entirely off LinkedIn

Start with a note only you could write, then hand the model editing work with the limits spelled out.

The post I'm replying to: [paste it]
What I want to say, in my words: [your note]
Turn my note into a comment under 60 words.
Don't add facts, numbers or experiences I didn't give you.
Don't praise the post or repeat what it says.

Cut any sentence that would fit under someone else's post, the swap test from the piece on comments. Then paste the text into LinkedIn's composer and post it by hand, at a human pace. I hold Handful's drafts to the same line: answer what the person said, and you decide whether it goes out.

Comments that add something, on the posts that matter.

Handful finds up to five LinkedIn posts a day from people who need what you sell, and drafts a comment in your voice. You read it, edit it, and post it yourself.
