For AI video creators · add the soundtrack layer your edit is missing
Sonilo is an AI music and sound effects generator built for video creators. Upload your video and Sonilo reads the cuts, pacing, and voiceover, then generates a synced, commercially licensed soundtrack for the key moments.
Free preview included. Just upload your video.
How it works
MP4 or MOV. Sonilo reads the clips, pacing, and voiceover. Your key moments tell it where to land.
Type one line for the mood you want. Or leave it blank and let Sonilo choose. Extra controls keep voiceover clear.
Get music generated to hit your cuts, reveals, and voiceover. Commercial rights start on Pro, with Enterprise and eligible API-user terms for teams.
Try it
Upload a render, get original music composed to your edit in seconds. Free plan included.
Why not stock. Why not a song generator.
Stitch three AI clips and you get three sounds that miss the edits. Sonilo generates music for the finished video. No prompt required.
You search for one that almost lands, then trim it by hand. Everyone else can use the same music.
Prompt tools do not watch your video. For a monetized channel, unclear rights become a risk.
Sonilo reads the full video and generates music that lands on cuts, reveals, and scene changes.
Creative control
Sonilo generates from your video, but you stay in control of what it sounds like.
One line is enough, or as much detail as you want. Prompt influence sets whether the video or your description has the final say.
Tense for the setup, open and bright after the reveal, without cutting the video. Missed a transition? Regenerate that segment instead of re-editing.
The music pulls back under voiceover and narration. Every generation returns multiple variations, and sound effects can come from the same upload.

Yes. Commercial use is available on Pro, Premium, Enterprise, and eligible API-user terms for monetized channels, sponsored posts, ads, and client work. Free and Creator are personal and non-commercial only.
Yes, that is the point. Sonilo reads the finished video, not each clip alone, and generates music that hits the changes.
No. Your video is enough. Sonilo reads it and generates music from it. If you want control, add one optional prompt, and extra controls let you guide key moments.
No. Sonilo keeps speech clear and lets the music sit under your narration.
Yes. Every generation returns multiple variations. Describe the direction, give different instructions to different sections of the timeline, set how strongly your prompt leads versus the video, and regenerate any section with tighter direction without re-editing the video.
Pick another variation, or regenerate with a more specific direction for the moment that missed: build into the reveal, shorter intro, lighter drums, more space under the voiceover. Change the timing instruction before changing the whole style.
