Frequently asked questions

How does the viral tweet scorer work?

The scorer analyzes your tweet draft across six dimensions: hook strength, length fit, reply potential, specificity, human voice (AI tell detection), and engagement cues. Each dimension is weighted to produce a 0–100 viral reach score aligned with how the X algorithm distributes content in 2026.

Is this the same score ViralGrok uses internally?

The free scorer uses the same scoring dimensions as ViralGrok's Grok-4.3 generation pipeline — hook, specificity, reply triggers, and AI tell detection. Paid generations add live X research and multi-angle drafts with full scoring.

Do I need an account to use the tweet scorer?

No. The overall score and dimension breakdown are free without signup. Create a free ViralGrok account to unlock all improvement suggestions and generate optimized rewrites with Grok-4.3.
