1) My goal:
I want to upload image files as app assets and use them in my Retool app, as described in Retool's file upload announcement.
2) Issue:
When I try to upload images through the Chat tab, the uploads fail and the images don't appear to actually be added as assets. However, the process still uses AI credits.
I've now run out of credits. The chat successfully made code changes that reference the images, but the actual image files are not there, so the app is pointing to assets that don't exist.
Is there a way to directly upload assets without going through the AI chat? It feels problematic that a basic asset upload currently requires consuming AI credits, especially when the upload itself fails.
3) Steps I've taken to troubleshoot:
Tried uploading the images through the Chat tab multiple times.
Allowed the AI chat to make the requested code changes.
Checked whether the uploaded images were actually available as app assets.
The code now references the images, but the image files themselves are missing.
Retried the process, which consumed additional credits.
I have now run out of AI credits without successfully uploading the assets.
Tried to drag and drop the images into the Code panel folders
4) Additional info:
Using the new app builder (not a classic app).
The issue is specifically with uploading image assets.
Has anyone else experienced this? Is there a workaround or a direct asset-upload option that doesn't require using AI credits?
Using the new app builder, attempts to upload image files as app assets through the Chat tab fail (the code references the images but the actual files aren't added as assets), yet the process still consumes AI credits — and there appears to be no way to upload assets directly without going through the AI chat.
AI Response
In the new app builder, uploading files as app assets is currently only supported through the Chat tab's 'Attach files' control (click the attach icon or paste files directly into the prompt box); dragging files into the Code panel folders is not a supported upload path, which is why that attempt didn't work. Note the documented limits: images up to 5 MB, documents/videos up to 20 MB, and a maximum of 10 attachments per message — uploads that exceed these can silently fail while the chat still edits code to reference them. There is presently no separate, non-AI direct asset-upload option, so asset uploads do go through the agent. Confirming files stay within the size limits and re-attaching them in a fresh message is the most reliable approach today, and heavy credit consumption in the new builder is a known, actively discussed concern.

Thank you for sharing these details with us! Really sorry to hear that the image upload has failed in the new app builder, and in this process, you have used up all of your AI credits.
I've shared this internally with our eng team who will be investigating this issue soon.
However, I'm missing your org details. I have DMed you privately to get your org details, so when you get the chance, please reply there so we can take a closer look at your situation and follow-up with you!
