Hey, author here. I made this to help technically curious people understand what's really going on when they're handed a Bitcoin seed phrase (i.e. why it's not just a password). You can flip bits of entropy, explore checksum validation, and see how mnemonic phrases are turned into deterministic wallets. Feedback welcome. If anything breaks I’ll fix it fast.
