LinkedIn's Post Proofreader edits your draft. It will not write it.
LinkedIn's Post Proofreader polishes an English draft you have already written, for Premium Career and Premium Business members only, so it can save you editing time but leaves the hard part, deciding what to say from your own work, with you.
LinkedIn has a new writing aid for posts, and it is deliberately smaller than the one it had before. Social Media Today reported that Post Proofreader replaces LinkedIn's AI post enhancement option(Social Media Today, LinkedIn ditches post enhancement, launches Post Proofreader, 2026-09-20), the tool that let members revise their posts with AI. LinkedIn's own Help page describes the new feature as an editing assistant that edits what you write instead of writing for you(LinkedIn Help, Post proofreader for LinkedIn posts).
What does Post Proofreader do?
You write a post, click Proofread at the bottom of the sharebox, and pick one of three modes. LinkedIn Help describes them this way:
- Review fixes spelling, grammar, and punctuation errors.
- Shorten makes your post more concise while preserving its meaning.
- Clarify makes your post easier to read and understand.
Suggested edits show up inline, with removed text struck through, and nothing is applied until you accept it(LinkedIn Help, Post proofreader for LinkedIn posts).
Two limits decide whether it helps you at all. It is available to Premium Career and Premium Business subscribers(LinkedIn Help, Post proofreader FAQ), and it supports English-language drafts only(LinkedIn Help, Post proofreader FAQ).
What does it change for you?
The blank page is still yours. The proofreader needs a draft to work on. LinkedIn's FAQ says you may get no suggestion when your draft doesn't contain enough content(LinkedIn Help, Post proofreader FAQ). If you are a consultant, coach or founder who rarely posts, commas were never the obstacle. The obstacle is deciding which client problem, decision or lesson from this week is worth a post, and getting it into words at all. LinkedIn's tool starts after that work is done.
If you post in another language, nothing changed. A draft in French, Spanish or German gets no suggestions. The same goes for anyone without an individual Premium Career or Premium Business subscription.
Run it last, and read before you accept. Manual editing is switched off while you review a suggestion, you can review only one enhancement at a time, and there is no version history, side-by-side comparison, or undo and redo(LinkedIn Help, Post proofreader FAQ). So finish your own edits first. Before you accept a Shorten or Clarify suggestion, check that the specific detail that made the post worth reading, the client situation or the number from your own work, survived the cut. If you are unsure, copy your draft somewhere before you start.
Where this fits
The proofreader is not LinkedIn's only recent move on AI written posts. It also added a report option for posts that seem like AI slop. We cover that option, and what it means for posts built from real work, in what LinkedIn's AI slop button means for your posts.
Read together, the two point one way: LinkedIn will help AI polish your words, and it is wary of AI supplying them. Amelia works at the step before the proofreader. She starts from your notes, voice memos and conversations, drafts from them, and you review before anything is posted.
