Terracotta UI
Clay
A free Claude skill for faceless motion-graphics reels
A narrated explainer in warm, editorial motion graphics. Everything on screen is drawn in HTML, CSS and SVG: headlines that slot in word by word, app cards, a prompt bar that types and rubber stamps, on paper with a fine grid. No footage and no face.

How to use it
- Morphy: it's built in. Open Settings → Community → Library.md and add Clay to a chat in one click.
- Claude Code: save the file as
~/.claude/skills/clay/SKILL.md, with the reference frames beside it asreference.jpg, then ask for a video or run/clay. - Codex or any other agent: add it as a skill, or attach the file to your first message.
Your first video
Make a 40-second clay reel: three free tools that replace a $30 app.
The agent checks your setup, writes the script, makes the voice, renders a few stills to check and then every frame, and hands you the MP4. Posting it is up to you.
Questions
- Is the Clay format really free?
- Yes. Download the .md file: no account, no email, no paywall. Use it for as many videos as you like.
- What do the voices cost?
- The voice comes from ElevenLabs. Its free plan is enough to try the format (about 10,000 credits a month, roughly one per character of script). Posting videos that promote anything needs a paid plan for the commercial licence, from $6 a month.
- Does it work with Codex too?
- Yes. It's a standard SKILL.md, the skill format Claude Code and Codex both read, and Morphy has it built in. Any other agent that can run code can follow it if you attach the file.
- Do I have to label the video as AI?
- On Instagram, a reel narrated by a realistic AI voice needs Meta's AI info label; switch it on when you post. On YouTube and TikTok, check the AI disclosure setting when the content looks realistic.
