- What counts as a render?
- Each video generation request counts as one render, regardless of video length or topic.
- Do unused renders roll over?
- No. Free renders reset at midnight UTC each day. Paid plan renders reset at the start of your billing month.
- Can I use my own OpenRouter key?
- Bring-Your-Own-Key is on the roadmap — coming soon.
- Can I cancel anytime?
- Yes. Cancel from Settings → Billing at any time. Your plan stays active until the end of the current billing period.
- What's the difference between models?
- Free-tier models (Gemini Flash, DeepSeek) are fast but occasionally produce Manim code with errors on complex topics. Hobby and Pro models (GPT-4o, Claude 3.5 Sonnet, Claude Opus 4) generate cleaner Manim code with noticeably fewer failures.
