I have other tools that include the checksum calculator and all... The problem I wanted to solve here is that people just want the words, in a secure way, and nothing else.
I deliberately don't include the other links for that reason. It's standalone, and meant that way.
I have a checksum calculator here as well: https://allesvoorbitcoin.be/bip39tool/checksum/

BIP-39 Word Raffle

Good idea, thanks!

My suggestion: you could add some 'how-to' section or explaining what is the BIP-39, where entropy comes from etc.

And the link to last-word-generator, like: https://seedpicker.net/calculator/last-word.html, so it is actually usable for people to generate their wallets.
