What users praise
- • Completely free and open-source under GPL-V3, with zero per-minute or per-project fees.
- • Runs fully offline with local models — no login, no usage limits, no data leaving your machine.
- • 30+ languages for recognition, translation, and dubbing with swappable AI engines.
- • One-click pipeline chains ASR, translation, TTS, and composition without manual stitching.
What frustrates them
- • Built-in TTS engines run 5-6 seconds slower than calling the same model via local API.
- • TTS reads each subtitle line separately, inserting unnatural pauses at sentence breaks.
- • A floating 'Loading resources...' overlay persists on top of all windows during use.
- • Point-version updates can introduce regressions like the v4.12 seed_value error.
