AI LinkedIn Post Writer
AI Ghostwriter's LinkedIn post writer turns a rough idea into a post with a hook up top, short paragraphs and no Markdown, in your voice if you've saved one. It checks the post against LinkedIn's 3,000-character limit, warns you when the first line runs past 210 characters (roughly what shows before “see more”), and runs a red pen pass to cut the AI clichés.

How to use it
- 01
Type what happened or what you want to say in rough notes: the story, the number, the lesson.
- 02
Pick LinkedIn post under “Use it for” and set the post type, tone, length, hashtags and closing question; More details adds the hook style and emoji.
- 03
Send it, read the hook and check the character count, then tap Better hook or Shorter, or tell it what to change.

Questions
How long should a LinkedIn post be?
LinkedIn allows up to 3,000 characters, and every draft is checked against that limit. Pick Short (400-700 characters), Medium (900-1,400) or Long (1,800-2,600) depending on how much story you have.
How much of a LinkedIn post shows before “see more”?
Roughly the first 210 characters, so the hook has to work there. The writer puts the hook in the first line or two and warns you if the first line runs past 210 characters.
What's a good hook for a LinkedIn post?
One that earns the second line: a bold claim, a concrete number, a confession, a question, a contrarian take or a specific moment. Leave Hook on Auto or pick one; a number hook only uses numbers you gave it.
How many hashtags should a LinkedIn post have?
Three to five specific ones, at the very end. With Hashtags on, the writer adds 3-5 after a blank line instead of sprinkling them through the text, and if you switch them off it warns you about any that slip in.
Can I put a link in my LinkedIn post?
Not in the body: the writer keeps links out of it and, if you need one, ends the post with “(Link in the first comment)”. Add the link as the first comment once the post is live.
Will my post sound like AI wrote it?
The red pen (Light by default) cuts stock phrases, breaks up a flat rhythm and shows a naturalness score before and after. It's an editing step, not a way past AI detectors, and it makes no promises about them.
