I’m working on Popgot ( https://popgot.com ), a tool that tracks unit prices (cost per ounce, sheet, pound) across Costco, Walmart, Target, and Amazon. It normalizes confusing listings (“family size”, “mega pack”, etc.) to surface the actual cheapest option for daily essentials. On top of that, it uses a lightweight AI model to read product descriptions and filter based on things like ingredients (e.g., flagging pean…

I like this idea a lot -- feels like there's a lot of room to grow here. Do you have any sort of historical price tracking/alerting? And/or also curious if there is a way to enter in a list of items I want and for it to calculate which store - in aggregate - is the cheapest. For instance, people often tell me Costco is much cheaper than alternatives, and for me to compare I have to compile my shopping cart in multipl…

(Specifically the size that fits in my pocket which I carry around. User #1 is me). Building in Common Lisp and targeting an Emacs mode…

https://mysukari.com - A Diabetes management platform I got diagnosed with type 1 diabetes in Feb (technically LADA as it's late onset). I'm the first in my family with it so I had zero info on it. I tried getting some CGMs to use but most don't work in Kenya as they are geo-locked, and even apps for measuring carbs like CalorieKing are not available in my region. I was really frustrated with the tech ecosystem, and…
