About this utility
How to use BIP-39 Mnemonic Generator & Validator
Generate cryptographically random English BIP-39 mnemonics or validate their word list and checksum locally.
What to provide
Paste a 12–24 word English BIP-39 mnemonic to validate, or choose Generate and leave this empty.
- Paste, type, or drag and drop a supported text file into the input area.
- Choose the options that match your intended result.
- Select “Run tool” or press Ctrl/Command + Enter, then copy, download, or move the result back into the first input for another pass.
What the result means
A validated mnemonic report or a newly generated checksum-valid mnemonic.
Privacy and safety
This utility is loaded as browser code and processes your input only in this tab. OmniCastConverter has no upload endpoint and never stores your content, filenames, tokens, or secrets. Generated markup and code are shown as inert text and are never executed.
Limitations
- A mnemonic controls funds when used by a wallet. Never paste a production recovery phrase into any app; use this with disposable test vectors or offline on a trusted device.
