I'm a big fan of creating useful things. It came to my attention in the pandemic years that I spent quite a lot of time and energy keeping track (and constantly updating) my day-to-day schedule and to-do list. One day I realized that I really would prefer to not have to do that manually, but none of the various to-do list apps or existing calendar tools that I found were exactly what I had in mind.
Since I couldn't find something that fit my needs, I created a Discord bot to take care of various scheduling needs for me. This allowed me to free up a lot of brain-space for more important things, a huge plus in my book.
This bot is just a simple Discord bot that has various text commands to set different types of reminders at varying time intervals. Made with Discord.py and sqlite. Full repository here.
