LinkedIn's feed is built for scanning, not reading. Readers make a split-second judgment on your first line, then decide whether to tap 'see more'. If your hook is too long, too vague, or buried in complex words, the post dies before it starts.
Short paragraphs, simple sentences, and a clear call-to-action are the three mechanics that consistently drive comments and reach. The readability score gives you a number for each one so you can fix the right thing.
This tool runs entirely in your browser. No API call, no account needed. Paste your draft, see the score update as you type, and use the tips to refine before you post.
