Frequently Asked Questions
What kind of captions does it generate?
The AI describes what it sees in your image — objects, scenes, actions, and context. Great for social media posts and accessibility alt text.
Does it work with any image?
Yes — photos, illustrations, screenshots, and more. Best results with clear, well-lit images.
