Explainer

Turns a URL into a 60-80 second walkthrough video with a talking head in the corner. Point it at a GitHub repo, product page, docs site, or blog post and it drives a real browser through the page, narrates what it sees, generates an avatar lipsync, and composites everything into a 1280×800 macOS frame. GitHub repos get special treatment with README scanning and live demo detection. The default flow is surprisingly autonomous: it generates a presenter avatar if you don't supply one, picks a voice, writes the script, and renders without asking permission at each step. Just a cost gate up front (can hit $5 depending on lipsync provider) and an auto-preview if it generated the avatar itself. Useful when you need a Loom-style explainer without recording one yourself.

/pika:explainer

Generate a ~60–80s URL explainer video: drive a real browser through the URL along a beat-sheet timeline, generate an avatar lipsync of the narration, and composite it all in a 1280×800 macOS Sonoma frame with a 240-pixel inner avatar (246-pixel outer including 3px white stroke ring) at canvas (20, 476) and element-targeted zoom on every mid-section beat. Works on any URL — product pages, docs sites, blog posts, launches. GitHub URLs activate a repo-aware mode (README scan + live-demo detection); all other URLs use a generic page-walkthrough flow.

Usage: /pika:explainer <url> [--focus "angles"] [--avatar <url>] [--voice <id>] [--lipsync-provider pika|kling] [--preview] [--live-url <url>]

Cost transparency gate

Before any paid MCP call, call identity_balance({verbose: true}) once. Surface the current balance, recent burn rate, and remaining runway, then gate the run with this exact message:

Estimated cost: about 50-500 credits (~$0.50-$5.00) depending on lipsync provider, narration, captions, and preview mode. This can reach $5, so Reply proceed to continue or cancel to stop.
