If you get 11 dice. Roll the 11 dice 23 times. Writing down 1 for even numbers and 0 for odd. Then convert each set of 11 digit binary numbers to a base 10 number between 0-2047. Print out a bip39 word list and match the numbers to the words. Get a valid 24th word checksum, and you are done. No need for AI or websites.

I don't trust myself not to make an error but I did investigate that option. For me it's better to reconcile the system result and trust my work.

If you made an error it wouldn't matter. That error would be unique to you and not reproducible.

Yes I wondered about that but with a lack of in-depth understanding on this I preferred a system. Now I actually have a bit more education on the matter, the paper option is totally valid.
