AI that learns your style and helps you create content faster. Creator AI analyzes your existing YouTube videos to understand your tone, vocabulary, and structure — then generates scripts, subtitles, ideas, stories, and more — all personalized to you.
- AI Style Training — Connect YouTube, provide 3–5 videos, and the AI learns your unique tone, vocabulary, and pacing
- Script Generation — Personalized video scripts via BullMQ worker; supports file attachments, storytelling mode, timestamps, multi-language output, and PDF export
- Ideation — AI-powered idea generation with live web search, trend snapshots, opportunity scoring, content angles, and sources; export as PDF/JSON
- Story Builder — Structured narrative generation from a topic with real-time SSE progress
- Subtitle Generation — Upload video (max 200 MB / 10 min), auto-generate timed subtitles, translate, edit in-app, export as SRT/VTT, burn into video via FFmpeg
- Audio/Video Dubbing — Dub media into 24+ languages via Murf.ai with real-time progress
- Billing & Subscriptions — Stripe-powered checkout, customer portal, webhook handling, and plan management
- Credit System — Token-based credits consumed per AI operation, tracked automatically
- Referral Program — Unique referral codes, track referrals, earn bonus credits
- Auth — Email/password and Google OAuth, OTP-based password reset, email verification via Supabase Auth
- Profile & Settings — Avatar upload, notification preferences, billing info
- Thumbnail Generator — AI-generated thumbnail descriptions (backend ready)
- Course Module Builder — Structured course outlines from a topic (backend ready)
- AI Video Generator — Page placeholder at

- Frontend calls Next.js API routes for AI operations (scripts, ideation) and the NestJS backend for subtitles, dubbing, training, and billing.
- Backend validates requests, manages auth, and enqueues long-running AI tasks to BullMQ.
- Workers process queued jobs (training, script generation, ideation, story builder) with SSE progress streaming back to the client.
- Supabase handles auth, database (with RLS), and file storage.
