AI Sound Effects for Videos

Mute a big creator's video and it still looks normal. Watch yours next to theirs with sound on, and you hear the difference: theirs has a whoosh on every cut, a riser before the reveal, a pop when text lands. Sound design is the invisible layer that separates polished from flat—and doing it manually means scrubbing an SFX library for hours. Eliro's AI reads your edit, finds the cuts and key moments, and places the right effect at the right frame.
