I built an AI tool that turns images into structured text (Captio)

I’ve been working on a small side project called Captio.

The idea is simple:

you upload an image, and it turns it into clean, structured text.

It works with:

• product photos


• screenshots / UI


• documents


• posters


• portraits

And generates:

• title


• key points


• description


• a clean summary

Why I built this

I kept running into the same problem:

Writing text from visuals is annoying.

Whether it's:

• describing a product


• explaining a screenshot


• summarizing a document

it always takes more time than it should.

So I built a tool to automate that.

How it works

1. Upload an image


2. Click generate


3. Get structured output in seconds

That’s it.

What surprised me

I expected it to work mostly on product images.

But it actually handles:

• UI screenshots


• random designs


• mixed content

much better than I thought.

Still early

It’s definitely not perfect.

Some outputs are great, others still need improvement.

That’s why I’m sharing it — I want to see:

• where it breaks


• what people expect from it

Would love feedback

If you try it, I’d really appreciate:

• what worked well


• what felt off


• what you’d want it to do better

Thanks 🙏
