FAQ

Questions answered.

Everything you need to know.

What does "Bring Your Own Key" mean?

Connect API keys from Google AI, OpenAI, OpenRouter, or Anthropic. Pay them directly at wholesale rates — no markup from us.

Is this really a lifetime deal?

Yes. One payment, forever. No monthly fees, no renewals. You own your license for life, including all future updates.

How much does AI cost on my own key?

Roughly $0.01–$0.03 per viral clip. Most creators spend under $5/month on API costs.

What AI models are supported?

Gemini 2.5 Flash, GPT-4o, Claude, and 100+ models via OpenRouter. You choose what works best.

What video formats are supported?

MP4, MOV, WebM up to 500MB. Or paste a YouTube link — we handle everything.

How does the Neural RAG Engine work?

Documents are parsed into a hierarchical tree with node-level summaries. At query time, an LLM reasons over the tree structure (not vector similarity) to locate relevant nodes — sitemap-first BFS crawling, multi-model reasoning via OpenRouter, and source-grounded citations on every response.

Can I add team members?

Pro includes 3 seats, Agency includes 10. Each member gets their own workspace with shared resources.

What if I need help?

All plans include community and docs. Pro and Agency include priority support.

Stop paying monthly.
Start creating forever.

One purchase. Every feature. Your own AI. No limits.
