-   **Smart Auto-Tidy**: Automatically fixes high-confidence errors (typos, specific homophones) instantly.
-   **Interactive Review**:
    -   **Synced Media Player**: Watch your video (or listen to audio) in real-time while editing.
    -   **Click-to-Seek**: Click any subtitle segment to jump the audio to that exact moment.
    -   **Inline Editing**: Fix any text manually with a simple click.
-   **Format Support**: Works with MP3 (Audio) and MP4 (Video).
