Frequently Asked Questions

How accurate are the captions?
They’re impressively accurate! The AI is trained on a huge variety of images, so it handles everything from nature shots to urban scenes really well.

Can it describe abstract or artistic images?
Absolutely. It’s great at picking up on style, color themes, and even the emotion in more abstract works.

What image formats does it support?
You can use common formats like JPG, PNG, and WebP—basically, whatever you’d normally work with.

Is there a limit to how many images I can process?
Nope, you can use it as much as you want. It’s designed for both occasional and heavy usage.

Does it work with low-resolution images?
It does its best! Higher quality images give better results, but even blurry or compressed pics often get decent captions.

Can I use this for commercial purposes?
Sure thing—the captions are yours to use however you like once they’re generated.

Will it recognize specific people or brands?
