Tune a post or thread for X against the engagement weights X published in its open-sourced ranker (replies 13.5, the author's replies to replies 75, likes 0.5, reports -369). Free: the page counts each post the way X counts characters, flags links, stacked hashtags, engagement bait and capitals, and charts the ten weights. A metered run says which engagements the draft invites or risks and writes three rewrites, each aimed at a different one, re-counted and checked so none adds a number, mention or link you never wrote.
