How it works

From your voice to a film

STEP 01

Upload audio or generate it from text

Planetanium transcribes audio and extracts the story. You edit the transcription, select the visual style and aspect ratio.

STEP 02

Agent helps

It breaks the story into logical parts: characters, locations, objects, scenes, shots - the storyboard. You can use your own images, or generate them using the latest generative models.

STEP 03

You direct

Watch the story grow on the timeline. Adjust timings, change properties, (re)generate images and videos, animate them. Talk to the agent about every detail by pointing at entities, fix mistakes, redo things, change your mind. The process is immersive and creative.

STEP 04

Export

Export to video or to a portable format which you can import into your video editor. Or just download all the assets and reuse them in your other projects.
