01 · Overview
Sheet hookline · 1/1
Know if your post will stop the scroll before you publish it.
Paste a LinkedIn draft, in French or English. Hookline reads it the way a stranger on a phone does and returns a /100 score explained pass by pass, a verdict on every sentence and five stronger hooks.
Harsh on purpose: the scale is anchored on what actually gets reach in 2026 (hook before "see more", paragraphs, no clichés, no bait). An average post scores like an average post.
02 · What you get back
Unpopular opinion: you don't need to post every day.
I tested it for 90 days with the same audience.
Three posts a week, twice the comments, and a lot less of the "what do I write today" anxiety that was eating my mornings before anything else got done.
Because one post that says something beats three that fill a slot.
Agree?

Stronger hook
Posting every day cost me comments.
I measured it for 90 days.
Red = cut, amber = rework. Every verdict comes with its reason; every hook with the question it plants in the reader's head.
03 · How it judges
Cold reader first
A dedicated pass sees only your first 140 characters and the shape of the post, and says whether a stranger taps "see more".
Rules you can check
Walls of text, clichés, bait, hashtag stuffing and question openers are measured in code and cap the score. Each cap is named on the card.
Versions, not guesses
Edit, analyze again, compare two versions side by side and watch the score move. Six scored passes, weighted and explained.
