I built Butterwell after watching too many bakers sell things at a loss because pricing felt like guesswork.
The pattern I kept seeing: someone makes a great product, they pick a price based on what "feels right," and they never account for ingredient cost fluctuations or their own time. Most don't want to touch a spreadsheet.
Butterwell lets you photograph your recipe — handwritten or typed — and uses AI to detect the ingredients. It then pulls live grocery prices and calculates what you should charge, with a breakdown showing ingredient cost, labor, and margin.
The live price data was the tricky part to get right. Grocery prices shift constantly and the gap between stale data and real data meaningfully changes the recommended price.
Currently in free beta. Curious what the HN crowd thinks about the pricing model approach.
