How It Works

From raw strings to shipped localization - 5 steps, fully managed.

Step 1

Create Project

Set up your game with genre, languages, and glossary

Step 2

Upload Strings

Drop JSON or CSV - auto-detect format, keys, and placeholders

Step 3

Auto Map & Translate

5-layer pipeline: context, tone, glossary, validation - all automatic

Step 4

Review & QA

Quality scores, issue detection, inline editing, approval workflow

Step 5

Export & Integrate

Download localized files or use the API in Unity, Unreal, Godot

More Than a Translation Tool

A full localization platform - project management, glossary, quality review, and integrations.

Smart Glossary

Define game-specific terms once, enforce them everywhere. Brand names, abilities, items - consistently translated across all strings and languages.

Quality

Translation Review

Quality scores for every string, issue detection (grammar, tone, meaning), inline suggestions, and team comments. No string ships without review.

5-Layer Intelligent Pipeline

Every string passes through five deterministic layers before reaching the LLM, then a final QA pass. Context-aware, not just word-for-word.

1

Project Context Profile

Project-wide knowledge injected into every translation.

  • Description, characters, locked glossary, do-not-translate
  • Sibling-aware speaker classifier
  • Default voice + player gender fallback
2

Context & Strategy

Decide WHAT each string is and HOW to translate it.

  • Context Engine — string type from key & file path
  • Classifier — regex + LLM categorization
  • Tone Engine — pick tone by genre, scene, string type
  • Strategy Engine — literal, creative, or standard
3

Constraints & Terms

Lock placeholders, character limits, and required terminology.

  • Placeholder protection ([player], {i}, %s, {0})
  • Character limits and format rules (UI overflow)
  • Glossary matching for game-specific terminology
4

LLM Translation

Single context-rich call with all of the above injected.

  • GPT-4o context-aware translation
  • SPEAKER + Voice Context block injection
  • Gender-preservation rule for gendered languages
5

QA & Repair

Validate, score, and surgically rewrite when something is off.

✓
  • Validator — placeholders, format parity, semantic loss
  • Quality Review — LLM-graded grammar, naturalness, tone
  • Glossary violation → targeted repair
  • Gender consistency → targeted repair
  • Auto-fix — plurals, format, profanity, dev-note leaks

Not Just Translation - AI Intelligence

Our neural translation engine doesn't just translate words - it understands game context, adapts tone, protects entities, and self-heals errors. Every string passes through 8 intelligent layers before delivery.

🧠

Context-Aware

Understands game context - quest, UI, combat, dialogue

🎭

Tone Adaptation

6 tone modes: epic, casual, formal, ironic, comic, poetic

🛡️

Entity Protection

Never translates player names, item IDs, or placeholders

🔄

Self-Healing

Auto-detects and repairs translation errors
