Add Music to Your Video — Free, Right in Your Browser
Drop a track onto your clip and Plumely mixes it on your device — it can auto-duck under your voice, fade in and out, or fully replace the original audio. Nothing is uploaded, and there's no watermark.
Everything runs on your device. Your videos are never uploaded — there's no server to upload to.
Auto-duck under speech
Turn on ducking and the music automatically dips whenever you're talking, then comes back up — so your voice always stays clear without manual volume keyframes.
Or let the music replace the audio
One toggle silences the clip's own sound so the track carries the whole video — perfect for B-roll montages and trailers.
Fades and level control
Set the music volume in dB and add fade-in / fade-out so it starts and ends smoothly.
