Drawing & Signatures
Let guests sign or draw on screen, transform the drawing with AI, and print it on their design.
Collect signatures and drawings in a survey with the Drawing question: canvas size, pen colours, AI transforms and printing the signature on the design.
Drawing question (signatures and doodles)
The Drawing question gives guests a pad to draw or sign on with a finger, stylus, or mouse. The strokes are saved with the response and can be placed on a drawing placeholder in your event template, so a signature or doodle appears right on the final design.
Drawing ratio
Pick the aspect ratio of the pad from the ratio picker (the default is 3:2). It decides the shape of the area the guest draws in.
Drawing pad width
Choose Small, Standard, or Wide (full width) to control how much of the screen the pad takes up on the guest's device.
Brush size slider
Turn Show the brush size slider on or off (it is on by default). The Undo and Clear buttons are always shown.
Style from the template
The color, transparency, and shadow of the strokes come from the drawing placeholder in the template, so the pad matches the final result. Without a placeholder, strokes are plain black.
Required and wording
Mark the question required and guests must draw something before continuing. The pad hint ("Sign here"), the Clear and Undo buttons, the Brush size label, and the required message can all be reworded in the survey's translation settings.
Mapping and responses
In Survey Mapping, a Drawing question can only be linked to a drawing placeholder (and the other way round), on the front or back of the design. The answer is also kept as a small preview image for the responses table and webhooks.
AI transformation
Turn on Enable AI Transformation to run AI on the guest's drawing, with the same options as Photo Capture: one or more prompts (reorder and copy them), a prompt image, an aspect ratio and reference photo per prompt, and Allow user to modify prompt. A drawing can also be the source for an In-line AI Processor or Post-AI Processor, and a previous Drawing question can be used as a Reference Photo in other AI prompts. When the guest taps Next, the drawing is uploaded as an image and the AI result replaces it (the original is kept). In Survey Mapping, a Drawing question with AI can link its AI output image to an image placeholder. Offline, the drawing is not uploaded and the usual offline AI notice is shown.
To let guests sign or draw on a design:
- 1
Add a drawing placeholder
In the template design editor, tap the + button, choose Add drawing placeholder, and pick a ratio. Style it in the drawing panel. See Using Event Templates.
- 2
Add the question
In the survey, choose Add Question and select Drawing. Give it a title such as "Sign your card".
- 3
Match the ratio
Set Drawing ratio to the same ratio as the placeholder.
- 4
Set the pad options
Choose the pad width and whether to show the brush size slider.
- 5
Link and map
Link the survey to the template and map the question to the drawing placeholder in Survey Mapping.
- 6
Test as a guest
Preview the survey, draw something, and check the result on the design.
Important: if you use this question as a dynamic question to replace a drawing placeholder on an event template, select the same ratio as the placeholder. If the ratios differ, the drawing is resized to fit inside the placeholder.
Great for signatures: title the question "Sign here" and see a full recipe in Advanced AI: trading card. To turn a sketch into AI artwork, see Advanced use cases: sketch to AI artwork.
