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 Optional cloud engines (BYOK) — OpenAI / Claude / Gemini with your own API key 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 Multilingual UI (JA / EN / KO / ZH) 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. Offline / local-LLM models download on first use (internet required), then run offline. Machine translation may not always be accurate. If you choose a cloud engine (optional), it needs your own API key, you are billed by that provider, and on-screen text is sent to their servers. The default offline engine sends nothing.
