Maybe you've created your own AR program for wearables that shows the definition of a word when you highlight it IRL, or you've built a personal calendar app for your family to display on a monitor in the kitchen. Whatever it is, I'd love to hear it.

A recipe manager for our family that strips all the SEO text out using the OpenAI API. I built this after someone in our family got diagnosed gluten intolerant and we had to make changes to our usual recipes.

Normal recipe sites tend to be full of irrelevant (SEO optimized) text, ads and tracking, and I wanted something to just get the recipe in a clean form.

It’s a basic web application (mostly in Go) to manage recipes. New recipes are imported from an URL, after which it extracts the plain text from the site and uses GPT to get a markdown formatted recipe and list of ingredients.

This would’ve been much harder pre-GPT, but now was trivial to implement.

Oh for sure. I think Paprika (?) does a decent job. To be fair, it started as a learning project for myself.

As a minor detail I also translate everything to the same language as part of the transformation. Just a bit of prompt experimentation.
