About Wave Subs

Wave Subs is a desktop application that creates SRT or ASS subtitle files from video files using local artificial intelligence. It processes videos entirely offline, recognizing dialogue with whisper.cpp and aligning timing against reference subtitles. The software supports automatic translation into 29 languages using a locally running Qwen3 model or an OpenAI-compatible API. Users can edit subtitles with a built-in editor that includes video preview, timing adjustment, and audio playback for verification. The tool handles multiple video formats including MKV, MP4, MOV, and TS, and can process entire folders of videos with shared settings. It provides quality verdicts to highlight sections requiring review and allows glossary customization to maintain consistency across translations. All operations occur on the user’s machine without uploading videos or requiring an account.
