Zero Broken Variables.
Ship your game in 15+ languages.
AI that preserves every {0} \n [color=#FFF] in your files — keeps your glossary consistent across every line — and matches your game's tone in every language.
Active Debuffs on Your Localization
Every AI translation tool promises quality. None of them understand game localization files. Here's what breaks.
Variables get mangled into fullwidth characters. Your game engine parser crashes on import.
Without a glossary, AI translates the same game term differently every time. Players get confused.
Generic AI writes like an instruction manual. Your dark fantasy game reads like a Google Translate dump.
L10nGuard Buffs
Every debuff, countered.
Variables and tags are locked before translation and restored after — byte for byte.
Auto-glossary extracted, reviewed by you, enforced across every line.
Set your genre and tone. AI adapts — dark fantasy reads like dark fantasy.
