Are TOR exit nodes safe?

So I’ve been trying to be more privacy conscious and I’ve been seeing a lot of suggestions to use TOR. With my very limited knowledge of TOR I’m slightly concerned about TOR exit nodes reading my data. I get that this is a vulnerability with other things like VPŅ, but I feel pretty safe with mine. Could I use both TOR and a VPŅ to protect against the exit node reading my stuff, or does that just defeat the purpose …
