Add sound effects to your video automatically
Sound design is the difference between a clip people scroll past and one they watch twice. It is also the part of editing most creators skip, because placing every pop, whoosh and hit by hand takes forever.
Auto SFX does it for you. It watches your video, detects the key moments and places production-quality sound effects on your timeline, matched to the content and tone of the clip.
Keep what works, swap what does not, and you are done.
Why creators add sound effects with Auto SFX
Minutes, not hours
A 60-second clip gets its sound effects in under two minutes.
Matched to the moment
Transitions, impacts, on-screen actions and ambient beats each get a sound that fits.
Fully editable
Every effect is a separate block you can adjust, regenerate or delete.
Funny, cinematic or subtle: it follows your tone
Auto SFX matches sounds to your video's content and tone, so a comedy skit and a product demo do not end up with the same effects.
Want something specific, like a cartoon boing or a deep cinematic boom? Generate it from a prompt and pick from three versions.

"Everything is automated, I don't have to find clips or worry about captions, it is all done for me. I use it two or three times a month, and find it is as easy to use on mobile than on desktop. It's easy to get started, and the clips can be easily uploaded to social media - I use them on Instagram on TikTok."
