Features

Live Converter

Type any text and see the full NATO phonetic breakdown in real time. Copy to clipboard or have it read aloud via text-to-speech. Perfect for use during active support calls.

Reference Grid

Full A–Z plus 0–9 reference with filtering and per-word pronunciation buttons. Includes the correct NATO digit pronunciations (e.g., "Niner" for 9).

Spell Drill

Given a hostname, IP, or custom string, spell out each character phonetically. Supports custom input or random IT-themed challenges like SRV-DC01, 172.16.0.50, WSUS-SRV01, and more.

Speed Quiz

Two quiz directions — see a letter and pick the NATO word, or see the word and pick the letter. Tracks score, current streak, and best streak. Supports keyboard shortcuts (1 2 3 4) for rapid-fire answering.

Call Simulator

Generates realistic IT scenarios — hostnames, IPv4 addresses, serial numbers, MAC addresses, or mixed — and has you read them out phonetically character by character. Timed with accuracy scoring.

Timed Challenge

30, 60, or 90 second countdown mode. Answer as many letter-to-word questions as possible before time expires. Tracks personal best across sessions. Countdown tick sounds in the final 10 seconds.

Additional Highlights

• Text-to-Speech — hear correct pronunciations on reference cards and drill results via the Web Speech API
• Sound Effects — synthesized correct/wrong/complete sounds via Web Audio API (no audio files needed)
• Keyboard Shortcuts — keys 1 through 4 for quiz and timed modes
• Persistent Stats — sessions, accuracy %, best streak, and best timed score saved to localStorage
• Mobile Responsive — fully usable on phones for quick practice between calls
• CRT Terminal Aesthetic — scanline overlay, green-on-black monospace theme
• Zero Dependencies — single HTML file, no build step, no frameworks, no CDN dependencies beyond Google Fonts
• Offline Capable — works without internet after first load (font falls back to system monospace)
