Hey Product Hunt! I'm Phoenix - and like a lot of people who post on X, I was mostly guessing at why some tweets fly and others die. Then I noticed xAI quietly open-sourced their ranking algorithm at github.com/xai-org/x-algorithm. So I built TweetAlgorithm. What it does: paste any tweet (up to 25,000 chars for long-form Premium posts), tell it whether you'll attach an image / video, and get: - A 0–100 virality score with a per-factor breakdown (engagement potential, content quality, hook strength, hashtag use, media fit) - Algorithm risk flags pulled straight from the public repo - out-of-network penalty, link dwell drop, hashtag-overload spam signal, the lot - 2–3 AI rewrites that preserve your voice but score higher What makes it different from the usual "AI tweet helper": the scoring isn't vibes. It's grounded in the actual engagement actions xAI weights in their ranker - favorite, reply, quote, dwell, profile_click, video_quality_view - plus the negative signals like mute / block / report that nuke your reach if you trip them. Free to try: signup gives you 10 credits (1 free analysis). After that it's $5 / $15 one-time packs, credits never expire, no subscription. → https://tweetalgori.com A question to kick things off: drop a tweet of yours that flopped and you wish you'd scored beforehand. Reply below - I'll run it through TweetAlgorithm and share the breakdown + rewrites publicly. Would love your feedback on the product, the scoring, the rewrites, anything.
