I asked AI, what "not to do with mnemonic sedd", and here is a 10-part answer to me. (pic below. all is legit, read them !)

But I rather like to quote my OWN rule, which probably can be concidered even more important:

Never EVER enter/type your seed on a device, which IS connected, has BEEN connected, or/and may be connected in the FUTURE to INTERNET. In any way. Be it your PC, tablet, TV-set, smartphone, game console, crypto wallet, .... anything.
Protect your seed from www/internet capable devices in any possible form, at maximum force your have. Amen
