Automatically remove filler words, pauses, and silences — just by asking AI
Clean up recordings — instantly
Use simple requests to remove anything from your speech
Eliminate filler words and pauses in seconds
Tired of cleaning up “um,” “uh,” “erm,” awkward pauses, and messy voice overs manually? Just ask Kai, Kapwing’s AI assistant.
Remove filler words, eliminate silences, or clean up speech entirely — Kai instantly delivers a natural, professional-sounding audio or video recording in seconds.
It's the ultimate tool for voice overs, narration, talking head videos, interviews, podcasts, or any recording that needs to a polished and professional finish.
Automatic clean up with studio-grade quality
Video and audio editing is full of tedious tasks — especially cutting stutters, speech mistakes, and filler words that hurt retention and slow narration speed.
These interruptions affect engagement on social media, make creators sound less professional, and require hours of trimming.
With Kai, you simply tell the AI what you want fixed, and it handles the heavy lifting. Whether you give a broad command like “remove all silences” or specify certain filler phrases you commonly repeat, Kai delivers a clean, polished result every time.
Faster audio and video editing
Kapwing’s streamlined workflow transforms narration cleanup for marketing teams, content creators, and podcasters who need studio-grade results quickly.
In the same studio you can eliminate background noise, manually split or trim, add subtitles, and finish your entire edit — all online, from one browser tab.
Teams and freelancers can collaborate in real time — reviewing edits, leaving feedback, and refining content in one shared platform. The payoff: cleaner audio, more confident speech, faster delivery, and professional-quality production without losing creative control.
