I don't post my seed at anyplace I have it on paper writed by hand, I'm totally noob programing I do it correcting what a AI do for me.
Why do you trust AI for your code when you are not an experience programmer like you said?
There are open source tools for you and they are coded by experts with years of testing, using and verifying by community. It's better if you trust those experts and their tools rather than trust AIs.
Trust or not, like LoyceV warned you, use those tools offline.
If I use those tools, I will only use it for a word in problem, not use it for all of mnemonic seed phrase because other words are fine, no need to test and take risk unnecessarily.
