Can I use a JR Pass for Kyoto Subway?

Excuse me, I'm a bit confused about transportation options in Japan. I'm planning to visit Kyoto and I've heard about the convenience of the JR Pass. But I'm wondering, does the JR Pass cover the Kyoto Subway system as well? Or is it only valid for JR trains? I'd like to make the most of my travel time in Kyoto and use public transportation efficiently, so any clarification you can provide would be greatly appreciated. Thank you!
