Lights. Camera. Nobody.
Give Lumen one sentence and it makes the Minecraft explainer: script, voice, block world, captions and music. It runs on your computer, with the Claude or ChatGPT plan you already have.
This explainer started as a sentence.
Nobody built it. Nobody cut it.
The whole brief
Why a bank run happens
-
01
Script
Your AI researches the topic, writes every line and files each fact with its source and how sure it is. The word count and timing stay live, and any line is yours to rewrite.
-
02
Voice
Each character gets a voice. Lumen cleans the audio and times every word, so one line can be voiced again without touching the rest.
-
03
Storyboard
Shots are planned against the words. This film has 11, and each one knows its set, its camera and where it starts.
-
04
Scenes
The AI stages every line in the block world and checks its own build: sets, actors, cameras, HUD and captions, 50 words all on time.
-
05
Review
Automated checks measure the film and list what deserves a look. Each note jumps to its moment, and the panel says plainly what it could not check.

- Built in
- The Minecraft Explained engine ships with Lumen. No mods, no game, no screen recording.

Not an official Minecraft product. Not approved by or associated with Mojang or Microsoft.
Point at it. Say what's wrong.
Click anything in the frame and the AI knows exactly what you mean. Scope a note to one element, one shot or the whole video. Lumen saves a restore point first, shows the shots that changed and keeps an Undo one click away.
- Ask
- Question the AI about a shot without changing a thing.
- Locks
- Lock a line, a shot or a voice and every AI run must leave it alone.
- Ultra Edit

A crew that never asks for lunch.

Not only blocks.
Lumen has more worlds than one. These seven films share one storyboard, one voice and one timeline, and they play in sync, so switching a look loses no time.
Everything else on the lot.
Three hooks
Three opening lines, each staged and voiced, compared side by side.
Timing budget
Lines past your target length light up. Shorten to fit, then accept or refuse the diff.
Channel presets
Language, style, narrator, captions and pace, saved once per channel.
Recurring characters
A cast with a look, a voice and a personality that stay the same film after film.
Voice auditions
The same line in up to eight voices, plus a pronunciation list that captions never see.
Styles from references
Drop in pictures or videos and Lumen measures a new look from them.
Sound design
Effects on the visible actions and a music bed that ducks under the voice. One mix, no AI.
Thumbnails
A master board and a board per video, with a style key learned from your references.
Memories
Tell it once. Every later build reads the rule, and styles learn from their own mistakes.
Personal brand
Import your own recording. False starts go, pauses close, captions and punch-ins arrive.
Several accounts
When one AI account hits its limit, the run moves to the next one signed in.
Effort test
The same video at each quality, side by side, with build time and tokens.
Your computer is the studio.
Your AI plan
Lumen drives the Claude Code or Codex you already signed in to, or an Anthropic or OpenAI key. It never sees your password.
Your files
Every project is a plain folder in Documents. Scripts, voices, scenes and exports stay there, and restore points are saved before each run.
Your voices
ElevenLabs or Fish Audio with your key, or a local voice that runs on your own GPU, free and offline.
Other worlds
Straight out of the export window. Sound on.
Film school
Seven short lessons, recorded in the real app.
Two plans.

Every style, every look, the whole editor.

Questions from the back row.
What do I need to run it?
A Windows PC, plus one AI engine: Claude Code or Codex signed in with your own plan, or an Anthropic or OpenAI API key. For narration, add an ElevenLabs or Fish Audio key, or use a local voice on an NVIDIA GPU. You also need Node.js 20 or later and FFmpeg on the computer.
Does Lumen see my Claude or ChatGPT login?
No. You sign in to the command line tool yourself, in your own terminal. Lumen runs that tool and never touches the password.
How long does a film take?
It depends on the length, the style and the build quality. On the bakery short in the credits above, each agent worked for three to six minutes, side by side. The final render of a 36 second 2D film takes about a minute.
Can it post for me?
Lumen exports the video, captions, thumbnail and text, then opens the upload page. YouTube upload works with your own Google Cloud client. Direct TikTok posting is waiting on the platform's audit.
Can I use my own voice?
Yes, with a local clone or a voice from your own account, as long as you have the right to use that voice.
What if I don't like a shot?
Click it and say what's wrong. Lumen saves a restore point before each AI run, so one Undo brings the old version back.
