Seed Phrase Confirm?

I'm trying to move my RVN from Binance to the Ravencoin official wallet. I wanted to be sure my seed phrase would attach, so i used https://ravencoin.org/bip44/ to check and make sure the seed phrase was associated with the right wallet. It seems sketchy to me to be typing in that seed phrase into anything whatsoever. Now I feel like the wallet may be compromised. True?

I can't figure out how to create a new wallet with new seed phrase in the Raven Core for Windows.
