What Simple SoapCalc does in ChatGPT
The Simple SoapCalc plugin handles the math of soapmaking inside ChatGPT. You describe the soap you want, such as a creamy bar for dry winter skin, and it gives you the exact amounts of lye, water and oils to use for the batch.
You can change the oils, the batch size or the superfat, which is the share of oil left unreacted to make the soap gentler, and see the numbers update. It also gives an honest idea of how the finished soap will behave and feel, such as lather and hardness.
The listing frames it as a way to skip spreadsheets so you can focus on the craft. Lye is a caustic chemical, so follow normal soapmaking safety steps whatever the numbers say. Prices are not mentioned. Check the website for plan details.
