FEATURES

• Live speech recognition: local Qwen3-ASR, or cloud Qwen / MiMo

• Machine translation: local Tencent Hunyuan Hy-MT2, or cloud Hy-MT2

• Speech synthesis: local Kokoro, or cloud MiMo, with voice cloning

(Current best combo: cloud Qwen3-ASR + local Tencent Hunyuan Hy-MT2-1.8B + local Kokoro-82M. All of the above can be extended via plugins.)

• Floating subtitle bar: click-through, streaming bilingual captions, stays out of the way while gaming

• Two-way call interpreting: WASAPI process isolation — broadcast both directions in meetings or co-op

• Browser extension: intercepts player caption streams at 0 ms into the translation pipeline

• Glossaries: terms.txt / terms.json force industry-correct meanings

• Themes & QML slots: customize subtitle styles and UI components

• History: full-text search, export, read-aloud, single-line copy

PERFORMANCE

Default engines run locally; download the models and work fully offline.

In cloud mode, latency depends on the service you choose.

The overlay is optimized with low VRAM usage. Enable click-through in fullscreen games — it won't get in the way of play.

WORKSHOP

Steam Workshop is supported.

Subscribe to community-made glossaries, subtitle themes, and voice packs, or build and publish your own extensions on the standard Python / QML contracts.

Local or cloud engines — your choice.

API keys and fees are opened directly with each vendor. TransBox does not resell third-party model services.
