Auto-FGD supports the following asset types as stimuli:
Images
Formats: PNG, JPG, JPEG
Maximum file size: 7 MB each
Videos
Format: MP4
Maximum 5 videos per study
Maximum file size: 100 MB each
Maximum duration: 180 seconds
Text There are two ways to add text assets:
Add Text button — click the Add Text button to open a modal, paste your text directly into it, and save. The platform stores it as a text asset for the study.
Attach Documents — upload a .txt file from your system the same way you would upload an image or video.
Maximum 5 text assets per study
Maximum 10,000 total words across all text assets combined
Built-in word counting, validation, and limit checks shown in the UI
Overall asset limits:
Maximum 10 assets per study across all types combined, up to 5 of which can be video
Maximum combined size across all uploaded assets: 300MB. Once your uploads reach this combined total, the platform blocks further uploads — even if you haven't reached the 10-asset count limit yet.
Example combinations: 5 videos + 5 images, or 2 videos + 4 images + 4 text assets, or 10 text assets
Fewer assets are allowed but cannot exceed these limits
Note: The 300MB combined-size cap is often the tighter constraint in practice. Five videos at the 100MB-each maximum would total 500MB — well over the 300MB cap — so a video-heavy set will usually hit the size limit before it hits the 10-asset count limit.
Mixed media: Images, videos, and text can be combined in a single study.
Design tip: Keep visuals clear with minimal text overlays for better AI comprehension.
