Bitcoin Seed Phrase Recoverer is a tool for people who are missing one word (and only one word) in their BIP39 seed phrase. It works by taking advantage of the fact that the last word of a BIP39 seed phrase serves as a checksum: thus, it can be used to reduce the number of seed phrases you have to try in your wallet software to gain back access to your Bitcoins.

Typically, my software will reduce the number of candidate words from 2,048 to about 128 for a 12-word seed phrase; 64 for a 15-word seed phrase; 32 for a 18-word seed phrase; 16 for a 21-word seed phrase; and 8 for a 24-word seed phrase.
