Pairs like B/D/P, M/N, and F/S blur together on a lossy audio channel. Distinct code words remove the ambiguity in a single pass.
The built-in reference chart doubles as a study aid for memorizing all 26 code words and the digit spellings.

A standardized set of code words for the 26 Latin letters and the digits 0–9, defined by ITU/ICAO and adopted by NATO. Each word is chosen to sound distinct over noisy or lossy audio.
Letters and digits are mapped to code words, but characters outside A–Z and 0–9 pass through unchanged. Punctuation like , or ! appears in the output as-is.
The official spellings are Alfa and Juliett to keep pronunciation consistent across languages. Only the official spellings decode back to their letter.
The digit 9 is Niner to avoid confusion with the German word "nein" (no), which sounds similar over a radio.
No. It's a one-to-one, fully reversible substitution. It doesn't hide data — it only makes letters clearer to hear and repeat.
No. Decoding compares words case-insensitively and splits on spaces, commas, and semicolons, so bravo and Bravo both map to B.
Never. All conversion happens locally in JavaScript. Your input is not sent to, stored on, or logged by any server.
