Post virality scorer
Score a draft post's hook, specificity, novelty and shareability before you publish.
Breaks 'will this do well?' into questions you can act on: hook strength, a concrete number or story, novelty for your audience, one-read clarity, emotional pull and shareability, with engagement bait counted against it. Rewrite the weakest part and score again.
