Best subtitle & caption generator for videos

For users handling longer videos or seeking faster processing and more control, [WithSubtitles](https://desktop.withsubtitles.com/) offers a **paid desktop application**. The desktop app brings all the core features of the free browser version offline, plus several enhancements that make it a powerful tool for serious creators.

Highlights of the desktop version:

- One-time purchase for a lifetime license (no subscription)
- Works fully offline without internet connection once AI model downloads
- Much faster export speed (\~25x faster than the browser tool)
- Suitable for any length videos, not just short clips
- Advanced subtitle editor with customizable styles, fonts, sizes, colors, and positions
- Export subtitles and full transcription text for any video length
- Runs on Windows and MacOS with stable performance even for heavy workloads

Creators use the desktop app for professional-level subtitling workflows where precision, speed, customization, and privacy are critical. Despite these extra power features, the main subtitle generation technology remains rooted in the same high-quality AI as the free version.
