常见问题解答

Is the generated caption always accurate?

No — like any AI model, it can miss specific details, names, or brands. Always review and edit the suggested text before publishing.

Does the image get uploaded anywhere?

No. The captioning model runs entirely in your browser — your image never leaves your device.
