Here are some of the responses to this from last year's jam:

angela-quidam: If someone wants to create an ePub, I created an easy to follow step-by-step guide. It's available for 5$ or for free as a community copy: https://angela-quidam.itch.io/ebook-express

Tanaguru can be used to test your background/foreground colors for appropriate contrast. If your colors don't meet the minimum contrast ratio, it will suggest other colors! https://contrast-finder.tanaguru.com/

Color Brewer was created to improve data visualization (mostly for maps), but it can give you a set of hexcodes based on certain criteria (i.e., colorblind safe, print friendly, photocopy safe, number of hues). https://colorbrewer2.org/#type=sequential&scheme=BuGn&n=3

Kapwing is my favorite video captioning and transcription tool! The auto captioning is really accurate and very easy to edit. You can do a couple free videos each month, but there are also reasonably-priced subscriptions if you need to caption more videos! https://www.kapwing.com/
