AI Vision — FAQ
Everything you need to know about the free image analysis tools.
Are the vision tools really free?
Yes. Image to Prompt and Alt Text are free with no account. They use the free Gemini API tier with vision support.
Which image formats are supported?
JPEG, JPG, PNG, WebP and GIF, up to 4MB per image. For best results use clear, well-lit photos or high-res renders.
Is my uploaded image stored?
No. The image is sent to the Gemini API to generate text, then discarded. PromptHub does not store or index your uploads.
Can I use the prompt for Midjourney?
Yes — choose Midjourney style and get a prompt with subject, composition, lighting and style tokens you can paste directly into Midjourney.
