My Workflow:
1. I prepared a point-form summary of What is Metacognition in WORD.
2. I opened PPT, and chose 'Create with Copilot.' A side pane appeared on the right.
3. I uploaded the above WORD, asked Copilot to turn it into a PPT, sticking to the content of the WORD WITHOUT adding in more content ideas.
4. After answering a couple of parameter questions (eg, style), it started to generate the slidedeck.
TAKEAWAYS
1. Output better than other apps like Gamma and SlideAI. It doesn't add in additional content ideas.
2. The points are presented in graphic forms in many of the slides.
3. The initial output lends itself to revision. (For example, I asked it to enlarge the font size a little.)
4. The biggest problem: The long time it takes.
