Voxel 3D
Voxel
A free Claude skill for narrated voxel 3D reels
One narrator explains something while a blocky toy world acts out every sentence. An orange Claude block and a creator in a blue cap stand on a wooden desk at night, in front of a huge window full of tiny lit city windows, and the props change with every line.

How to use it
- Morphy: it's built in. Open Settings → Community → Library.md and add Voxel to a chat in one click.
- Claude Code: save the file as
~/.claude/skills/voxel/SKILL.md, with the reference frames beside it asreference.jpg, then ask for a video or run/voxel. - Codex or any other agent: add it as a skill, or attach the file to your first message.
Your first video
Make a 50-second Voxel reel about the three apps I use to plan my week.
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 Voxel 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.
