Paste a tweet and hit Score to see your viral reach breakdown.
The ViralGrok viral tweet scorer estimates how a draft may perform against X-style ranking signals. It returns a 0–100 viral reach score across six dimensions: reply potential, dwell & read time, share & repost, hook & scroll-stop, content quality (including human-voice / AI-tell risk), and algorithm risk. Paste any tweet—including output from other AI tweet generators—to see which dimensions are weak before you publish. No account is required for the core score and dimension breakdown; a free ViralGrok account unlocks deeper improvement suggestions and Grok rewrites. The free scorer uses the same scoring dimensions as ViralGrok's generation pipeline; paid generations add live X research and multi-angle drafts with full scoring. It does not claim official X algorithm weights or 100% AI-detection accuracy. Use it as a pre-publish checklist to edit hooks, reply triggers, and risk patterns—not as a guarantee of impressions or virality.
ViralGrok researches live X conversations, then writes humanized drafts with hooks and pacing tuned for impressions and replies — scored for reach and AI tells. 20 free credits per month — no credit card.
The scorer models X's ranking signals: reply potential, dwell time, share/repost signals, hook strength, content quality, algorithm risk, and AI tells / human-voice risk. Each dimension feeds a 0–100 viral reach score so you know if a draft can perform — and if it sounds robotic.
Yes. AI tells and human-voice signals are part of the score. Use it to catch robotic lines before you post — a free bridge from "sounds like ChatGPT" to a cleaner edit. It does not claim 100% AI detection accuracy.
The free scorer uses the same scoring dimensions as ViralGrok's latest Grok generation pipeline — hook, specificity, reply triggers, and AI tell detection. Paid generations add live X research and multi-angle drafts with full scoring.
