Quick answers
Frequently asked questions
Does Image Caption Generator upload my photo?
No. The image is processed in your browser after the model files download. The first download is about 250 MB and may take several minutes on a slow connection.
Can I publish the generated caption without checking it?
Review it first. The model can miss context, invent objects, or use wording that does not fit your audience. Edit the suggestion before sharing.
