Guest Inputs allow participants to influence how their photo is generated. When enabled, participants are prompted to answer questions immediately after capture and before the AI image is processed.
For example, you can let guests choose a theme, pick a color, or enter custom text to be incorporated into the final result. While many effects in the AI Effects library come with built-in inputs, users on Pro and Select plans can also create their own custom input questions and parameters.
How it Works
To use Guest Inputs, you follow a three-step logic:
Create the input (The question the guest sees).
Define the placeholder (The "variable" name the computer uses).
Add the placeholder to your prompt (Linking the guest's choice to the AI).
You can add multiple guest inputs to a single prompt to create highly personalized results.
1. Create the Input
From the Guest Input Settings section of your AI Effect:
Select the + button.
Select a Prompt Type:
Text: Guests type a custom response (e.g., "Enter your name").
Picker: Guests choose from a list you provide (e.g., "Choose a background: Jungle, Space, or Ocean").
Enter the Question participants will see on the screen.
2. Define the Placeholder
Every input needs a "Placeholder" or variable name. This acts as a shortcut for the app to know where to insert the guest's answer.
In the Prompt Placeholder field, enter a simple, one-word name (e.g.,
themeorcolor).If using a Text prompt, add an example value to guide guests.
If using a Picker prompt, add the selectable options you want guests to see.
Save and close.
3. Link the Input to Your Prompt
The guest's choice won't affect the photo until you "summon" it inside your AI Prompt.
Return to your Prompt Settings.
In the prompt text box, type your variable name surrounded by double braces:
{{theme}}.Example: "A person standing in a {{theme}} environment."
Alternatively, you can select the placeholder name from the list displayed beneath the prompt field to insert it automatically.
