Prompt Guides are instructions that tell Agent One exactly how to behave when working with a specific model. Instead of describing your preferences every single time you generate something, you set them once and Agent One follows them automatically.
Think of them as standing orders for each model, your rules, your style, your non-negotiables, baked in from the start.
How to find Prompt Guides
Inside your project, click the Context tab → click [ edit ] → in the pop-up window, select Prompt Guides.
You'll see a set of default guides already in place, one for each major model invideo uses, including Nano Banana, Veo, Sora, Kling, and ElevenLabs Voice Design. These are worth reading through before you start, they give you a clear picture of how each model thinks and what it responds well to.
Default Prompt Guides
Invideo ships with ready-made guides for the following models:
Nano Banana - for image generations
Veo - for video generations
Sora - for video generations
Kling - for video generations
ElevenLabs Voice Design - for voice generation
These are active by default and have been written to get the best out of each model out of the box. You can read through them, edit them, or leave them as they are.
Creating your own Prompt Guide
Have a specific way you want a model to behave? Click + New prompt guide at the bottom of the Prompt Guides section to create your own.
You might use this to:
Always generate images in a specific visual style
Ensure a consistent camera angle or lighting across all video generations
Set a default voice tone or pacing for all audio output
Define rules for a specific character or brand asset
The more specific your guide, the more consistently Agent One delivers exactly what you're after, without you having to repeat it every time.
A few things worth knowing
Prompt Guides apply automatically to every generation using that model within your project
You can have multiple guides and they stack alongside your Context
Editing a guide updates it immediately for all future generations in that project
Guides are per project, they don't carry over to other projects automatically
