# Letter to Mr. Matt Rickard on 2022-11-28

Dear Mr. Rickard,

It's Sunghyun. I hope you had a great Thanksgiving break — I've been great! I hope to work on some projects on curating human knowledge and sentience, which I've been delving into these days.

I recently had an idea for a hypothetical product, "Let's Alter." I have a vision but need clarification on where to start.

Let's Alter is a non-profit product that uses Generative AIs to describe any image on the web. For example, given an idea of dogs playing frisbee, AI will put the following as such.

ALT: Three white dogs are playing frisbee on a lawn with a woman wearing a red skirt

Facebook and Instagram have been doing this for a while, but AFAIK there are no open-source products. As Generative AIs evolved, I expected it to be possible to reverse Gen AIs to take images and spit out different variations of descriptive texts.

The final goal is to create a product like Let's Encrypt, which heavily contributed to removing unencrypted websites on the web. I imagine a future where no single image on the web is missing the alt tag with this technology.

What would be a logical first step to diving into this goal? Any ideas or meta-ideas that come to your mind?

Any help would be heavily appreciated.

Best Regards, Sunghyun Cho

### Implementation Suggestion​

• CLIP inference server + Library that wraps an image component (raw img or next/image)
function AltTextImage() {...hash image on the client...check if a hash exists on AltTextDB...if it does, set alt text...if it doesn't, upload the image and the alt text will be returned (hash + maybe image is stored in DB)}

### Transparency Logs​

• Possible incorporation of a transparency log like Let's Encrypt.
• Maybe a log of image hash → alt that anyone can contribute?
• Maybe Common Crawl is a better model?
