Your app won't crash
when translated.
We know localization is the last thing you want to deal with before shipping an update. Drop your app, website, SaaS, game or subtitle file, get every string translated — variables locked and verified, nothing skipped, no copy-pasting into ChatGPT. No login required.
Free preview: one cheap AI pass on your first 5 strings. The full pipeline locks every variable, verifies each string, and covers all lines.
Try it — no login required
Paste your strings. Watch your variables lock.
This is the exact moment your {player_name} tags get protected. The AI never sees them — only [[LOCK_0]] placeholders do. Locked before, verified after — your app won't crash when translated.
Preview runs the real VariableLocker — same code as production. No AI call, no storage, $0 cost.
Why localization breaks when products keep changing
Your app, website, or product keeps shipping. Agencies want $2,000 and weeks of coordination. Generic AI mangles your {player_name} tags, skips long strings, and leaves you fixing broken JSON after the release. You need the latest files back, ready to ship.
We lock your variables before the AI sees them, verify them after. Every string translated — no skips, no truncation. Drop your latest files, get a production-ready folder back, then repeat when the product changes.
Variable-safe translation — every protection tested
7 variable presets, 4 glossary rules, 8 injection patterns, 5 edge cases — all verified before the AI touches your strings.
{0:plural:1 Apple| Apples}{0:plural:1 Maçã| Maçãs}Plural formatters with pipe-delimited options — the entire token is locked as one unit.
{0:choose(1|2|3):one|two|three}{0:choose(1|2|3):um|dois|três}Choose formatter with enumerated values — pipes inside parentheses and after colon all preserved.
{0:{Name}}{0:{Nome}}Nested scope syntax — inner braces matched as part of the outer token.
{player_name}, NO SURPRISES AFTER UPLOAD
Here's exactly what we handle.
2-pass AI pipeline. We translate strings. We don't touch your layout, your voice acting, or your pricing. That's not a limitation — it's focus. You ship the build, we've got every string.
Translate
Heavyweight AI captures cultural context, game terminology, and natural language structure.
Refine
Cross-model native editing catches stiff phrasing, fixes cadence, ensures natural flow.
Verify
Deterministic verification enforces token preservation, JSON validity, and length-density guardrails — no guesswork, nothing left for a third AI pass.
What we handle
-
String translation across 27 languages — every string, no skips.
-
Variable locking — {player_name}, %s, Smart Strings, HTML tags stay put.
-
File structure preserved — keys, nesting, format intact.
-
Custom glossary lock — branded terms, character names, your call.
What you handle
-
UI layout & font sizing — German runs ~30% longer. Your engine, your call.
-
Cultural LQA & voice acting — AI translation, not human QA.
-
Regional pricing & currency — we don't touch your numbers.
You ship the build. We've got every string.
Real project, same pipeline
We use LocaFile AI on our own projects.
We built this because our own products keep changing. FastOG, BeCaSimulations, and Truck Empire went through the same localization workflow we make available to you.
This is first-party proof, not a customer testimonial: real projects, processed with our own tool.
