I’ve goofed up in presentations plenty of times because I didn’t practice enough or I got nervous. Thankfully, Microsoft PowerPoint‘s AI-powered coach can help you avoid those mistakes.

The coach was first released in 2019 on the web. Now, it’s now rolling out to all platforms — Windows, Mac, iOS, and Android. In coach mode, the AI listens to your presentations and gives you suggestions based on your tonality and delivery.

For instance, it will give you a warning not to use too many “umm”s and “ahh”s. Plus, the coach will ask you to vary your tone if your delivery is too flat.

I used this feature on the Android app and basic word and tone detection work well. One time, when I got frustrated and said “fuck,” the coach reminded me to avoid using profanities.

Microsoft says the AI also helps you pronounce words correctly. However, it’s trained on “General American English” for now, so if you pronounce a certain word differently in your region, you can avoid the coach’s suggestions. If you feel that you’re not pronouncing a word correctly, Microsoft will suggest you listen to the coach say it.
