Grow an idea into a film

Lumibelle is a personal video studio. Write the script, build your cast and locations, compose shots and cut them together, with AI help wherever you want it.

Free and open source. The Windows download is an unsigned preview build, so Windows may ask you to confirm the first launch.

Four studios, one film

Script

Write a screenplay with scenes and acts, or ask the assistant to outline, revise and continue. Every AI change is a proposal you review first.

Assets

Pull characters, locations and props out of the script, then generate, edit and approve reference images for each one.

Shots

Plan coverage, pick references, compose prompts and generate takes, all in one workspace.

Cut

Assemble takes on a timeline, trim to the frame, swap alternatives and export an MP4.

Yours, on your computer

Local projects

Projects are readable files in a folder you choose. Back them up by copying the folder.

Bring your own models

Connect ComfyUI for local image, video and text generation, or OpenRouter, Claude Code and Codex for hosted text models.

AI is optional

Writing, asset editing and cutting all work by hand. Nothing is generated unless you ask.
