Write your own script or let AI write it

You can start a video two ways. Give AITuber an idea and AI writes the script, or paste your own script and AI adds the visuals and voice.

Idea to Video or Script to Video?

At the top of the input box you see two tabs.

• Idea to Video: Type a short idea. AI writes the words and picks the visuals.
• Script to Video: Paste your own words. The voiceover follows your script exactly.

Pick Idea to Video when you want speed. Pick Script to Video when the exact wording matters, for example a brand message or a translated script.

How do I control the visuals with [brackets]?

In Script to Video, put a visual description in square brackets before the words that go with it. The text in brackets becomes the scene image or clip. The text after it becomes the voiceover.

Example:

[A dark forest at night] Something was watching from the trees.
[Close-up of glowing eyes] It had been waiting for years.

Brackets are optional. If you skip them, AI picks the visuals for each part of your script. Some video types have their own bracket style. For example, a Skeleton video script looks like this:

[3D skeleton in a dark room] What happens to your body if you...
[Brain inside skull glowing] Your brain starts to...

Can AI write or improve my script?

Yes. The script box has built-in AI tools.

1. Click Get ideas to get video ideas about a topic. This costs 2 credits.
2. Click Write script to turn an idea into a full script. Pick a length and language first.
3. When your script has at least 20 characters, the button changes to Improve script. Tell it what to change, for example "Stronger hook" or "Add [visual] directions".

Write script and Improve script cost 1 credit per minute of script length, with a minimum of 1 credit. A 5-minute script costs 5 credits to write or improve. After writing, you get two versions (A and B) and can switch between them. After improving, you can switch back to your original.

How long can my script be?

The voice speaks about 3 words per second. Use this to size your script:

The character How long can my videos be? for the maximum length of each video type.
