AI tools are developing so fast, by the time I post this, some points will already be out of date.
Rather than fearing the technologies and their advances, I prefer to embrace them, test them and include them in my workflow if there are any benefits for me, the learners, my clients. Below is a list of various AI Tolls that could be used during the various phases of development of learning materials (digital or not).
I am not advertising, promoting but listing some of the tools I came across. I have not fully tested them all.
