⚡ What Does ViralLead AI Do?

ViralLead AI automatically processes YouTube Shorts, TikTok videos, Instagram Reels, Facebook Reels, podcasts, and Twitter/X videos to:

1. Transcribe Speech-to-Text: High-accuracy transcripts with timestamps using native subtitle streaming and ultra-fast Groq/OpenAI Whisper.
2. Detect the Viral Hook: Pinpoints the opening 3–5 seconds hook sentence and classifies its psychological persuasion angle (Curiosity Gap, Negative/Contrarian, Direct Question, Bold Claim, Story Frame, How-To).
3. Calculate Virality Score (1–100): Evaluates hook punchiness, pacing (words per minute), emotional resonance, and retention appeal.
4. Auto-Generate Repurposed Content:
   • 🐦 Twitter/X Thread: Ready-to-tweet 4–5 post thread with viral formatting.
   • 💼 LinkedIn Post: Thought-leadership formatted post with whitespace and punchy hook.
   • 📧 Newsletter Breakdown: 3 core bullet lessons + quote for Substack / Beehiiv.
5. Extract Creator Metadata: Channel name, creator handle, video duration, view count, like count, and direct thumbnail URLs.
