The Story

Growing brands were drowning in Instagram comments — thousands per day, impossible to keep up with manually. Ignoring them killed engagement. Hiring a team was expensive. We built ReplyMagic to sit in the middle: an AI that reads each comment in context, generates a brand-voice reply, and posts it in under a second. It scaled to 50K users organically and has sent over a million replies.

What We Built

  • Instagram Graph API integration with real-time comment webhook handling
  • GPT-powered reply generation with per-brand tone and voice configuration
  • Sub-second response pipeline using queued workers
  • Web dashboard for managing brand settings, review queues, and analytics
  • Stripe-based subscription billing with usage tiers
  • Onboarding flow that extracts brand voice from existing content automatically

Results

  • 50,000+ users acquired with zero paid advertising
  • Over 1 million AI-generated replies sent across all accounts
  • Sub-second average reply time — faster than any human team
  • Brands reported 3–5x engagement rate increases after activating
