Ask HN: What are the things that you have automated in your personal life?
After starting to do groceries via an online supermarket that delivers to our home, I found it a hassle to add all ingredients one by one every time. 
So I "reverse engineered" the supermarket app API via a proxy, and made a tool to order recipes. When ordering a recipe, all ingredients are added to the cart. We use the tool for almost one year and it saved us a lot of time.
