Game Overlay Translator

Turn on-screen English into your language, in place

Game Overlay Translator reads the text on your game screen and overlays the translation right on top of the original — no window switching. It works fully offline, with unlimited translations and no subscription.

Great for

• Playing games with no localization — understand menus, quests and item text as you go
  
• Reading story and dialogue — translate NPC lines on the spot
  
• Translating just one area — drag to select a region; only that box is translated
  
• Doujin, indie and older PC games — comfortable even without an official translation

Features

• Full-screen translate (one hotkey) and region translate (movable box)
  
• Fully offline (recommended) — no internet, unlimited, high-quality local model
  
• Optional local LLM (Ollama) for more context-aware results
  
• In-place overlay — original text blended out, translation drawn in the same spot
  
• Glossary to fix game-specific terms to the wording you want
  
• Display customization — font size, color, background opacity, selection-box color
  
• Translate into 33 languages — 19 European languages added. Major languages are bundled and fully offline; some European languages download once automatically on first use (offline afterwards)
  
• Multilingual UI (19 languages)

A floating control bar

While translating, a small on-screen bar gives one-click access to full-screen / region translate, auto mode, history and settings.

How it works

Screen capture, OCR, translation, then in-place overlay. Results are cached locally for instant re-display.

Important notes

• As an on-screen overlay, games with anti-cheat (EasyAntiCheat / BattlEye / VAC, etc.) may warn, kick, or penalize your account. Use with online/competitive games at your own risk and check each game's ToS.
  
• May not appear in exclusive-fullscreen games — use borderless/windowed mode.
  
• Machine translation may not always be accurate.

About translation quality (honestly)

The default engine is offline machine translation: fast, free and good enough for menus and quest text, but not literary. The screenshots show real, unedited output. If you want more natural, context-aware translations, the free Ollama integration runs a local LLM. And any translation you dislike can be pinned to your own wording with the glossary feature.
