# LLMSketch

> Text to hand-drawn explainer videos. One sentence in, whiteboard sketch video out.

LLMSketch turns plain English into hand-drawn whiteboard explainer videos, static SVG
diagrams and animated SVGs. Deterministic CPU rendering means labels, arrows and numbers
are always exactly correct — no generative-video garbling.

## Products
- Sketch video (MP4, 1280x720, hand-drawn draw-on animation, ~20-60s render)
- Static SVG diagram (site builds, ~12 KB, infinitely scalable)
- Animated SVG (SMIL stroke draw-on, zero JavaScript, web heroes)
- Lyric videos (any song -> timed sketch lyric video, built for music catalogs)

## Pricing (USD)
- Credit Pack: $15 one-time, 50 render credits, never expire
- Starter: $19/month, 60 renders/mo, voiceover + background music
- Pro: $49/month, 250 renders/mo, 1080p, custom audio, webhooks for n8n/Make
- B2B Fast Pack: $249 one-time, 10 custom explainer videos delivered in 24 hours
- Free previews: 2 per IP per day, watermarked, no signup

## How it works
1. User describes a diagram in one sentence (or passes SceneSpec JSON)
2. A local LLM writes the scene: nodes, arrows, labels, timing
3. Sovereign CPU renders hand-drawn jittered strokes frame by frame (PIL + ffmpeg)
4. Output: MP4 / SVG / animated SVG
