Instant structure check · 0/100

Paste a post above to see the check.

  • × Hook: Start with a one-line hook that makes people tap “see more”.
  • ! Length: Very short. Fine for a question post; add context if you want dwell time.
  • ✓ White space: Paragraphs are short and scannable.
  • ✓ Sentence length: No sentences yet.
  • ✓ Hashtags: No hashtags — optional; add 1–3 specific ones if they help discovery.
  • ! Conversation starter: Close with a specific question to invite comments (not “thoughts?”).
  • ✓ External link: No outbound link in the post body.
  • ✓ Styled text: No Unicode styling.

Written by AI on demand — nothing runs until you press the button. Always check facts and make it sound like you before posting.

What the optimizer looks for

A hook that fits above the fold. On phones roughly 140 characters show before “…more”. A first line under 70 characters lets the reader see the hook and the start of the next line — enough to want more.

White space. Paragraphs over about 35 words turn into a wall on a phone screen.

A real question. Posts that end with a specific question get more comments than those ending in a statement or a vague “thoughts?”.

Restraint. Three to five hashtags, few Unicode-styled characters, and caution with outbound links.

Everything else — whether the idea is interesting, whether it’s true, whether it sounds like you — is your job. Format the final version in the formatter.

Questions people ask

What does the LinkedIn post optimizer check?

The instant check looks at structure: hook length against the phone fold, total length, paragraph size, sentence length, hashtag count, whether you end with a question, outbound links and how much Unicode styling you used. The AI rewrite then improves hook, tone and flow without adding facts.

Will the AI change my facts?

It is instructed to keep every number, name and claim you wrote and not to add new ones. Always read the rewrite before posting.

Is the score a prediction of reach?

No. It measures readability and structure, which you control. Reach also depends on your network, timing, topic and whether the idea is worth reading — no tool can score that honestly.

Does it matter if I put a link in my post?

Many creators report that posts with outbound links get less distribution, and LinkedIn has said it wants to keep people on the platform. Testing the link in the first comment is a common workaround; results vary.
