2. Import your video or audio file
3. Descript transcribes it automatically (very accurate, AI-powered)
4. Edit the transcript to edit the video. Delete filler words ("um," "like") with one click.
5. Use Studio Sound to clean up audio (removes background noise, enhances voice)
6. Add captions, transitions, screen recordings. Export to MP4, publish to YouTube, or share a link.

Key features:

• Filler word removal: One click removes every "um," "uh," "like," "you know" from your recording
• Eye Contact: AI adjusts your eyes to look at the camera even when you were reading notes
• Studio Sound: Makes any recording sound like a professional studio
• Green Screen: AI removes your background without a green screen
• Overdub: Clone your voice and generate audio corrections. Misspoke? Type the correction and your AI voice says it.
