Most advice about first lines comes from other people's posts and other people's readers. This skill starts from yours. Give it your posts with their numbers and it finds the openings that did better than your own median.
It names the shape of each one (a figure, a claim, a moment, a question, a contrast or a list), then writes three new first lines for your draft in those shapes. Every fact in them comes from the draft. With fewer than five measured posts it tells you there is no pattern yet.
- Works from the LinkedIn analytics export, a spreadsheet of your own, or posts pasted in with their numbers.
- Shows a table of your winning openings, with shape, length and result.
- Never reuses an old sentence and never carries a number over from an old post.
