Manual vs. AI: Revolutionize Your Video Workflow

Manual Video Captioning

Labor Intensive

Spending hours listening, typing, and manually dragging text blocks to align with audio.

Syncing Errors

High risk of "subtitle lag" where text doesn't match the speaker, ruining the viewer experience.

High Fatigue

Constant rewinding and re-typing leads to editing burnout, especially for long-form content.

Language Limitations

Struggling to accurately transcribe and time-stamp languages you aren't 100% fluent in.

Complex Re-editing

If the audio changes slightly, you have to manually shift every single subtitle block again.

AI Auto Captioning

Instant Generation

Add subtitles to video in minutes. The AI does heavy lifting while you focus on creativity.

Perfect Timing

Millisecond-level synchronization ensures your AI subtitles are always perfectly in-sync with the voice.

Effortless Flow

Avoid the "rewind-replay" loop. Review a completed draft and make quick edits in a simple interface.

100+ Language Support

Leverage professional auto captioning for over 100 languages, expanding your reach instantly.

Dynamic Flexibility
