Seed word lookup

Check whether a word belongs to a seed phrase word list. Search BIP39 in all 10 languages, SLIP39, old Electrum and Monero by word, by number, by binary, or paste a whole phrase.

Try abandon, a number like 1560, 11-digit binary like 11000010111, or paste several words to check a whole phrase.
