Licensed AI music generator that scores a soundtrack directly from your video — no text prompts.

Sonilo is an AI music generator built for video. Its headline trick is that you do not write a prompt at all: you hand it a clip, and it reads the footage — pacing, motion, cuts, structure, and emotional arc — then composes an original soundtrack that fits. The track is generated to the exact length of your video and resolves on a real musical ending rather than a hard cut or a loop. Rather than returning one result, Sonilo produces several variations from the same footage so you can audition styles and pick the one that lands. The company is based in Menlo Park, California, and led by CEO Shawn Song, whose framing for the product is that "the information needed to score a video is already inside the video — so why are we still writing prompts?"
The pitch creators care about is the rights story. Sonilo's models are trained on professionally licensed content, including Shutterstock's music catalog, with the musicians involved compensated. Output is positioned as production-ready and cleared for commercial use on its paid plans — a meaningful difference from generic AI-music tools where the licensing for monetized or branded video is murky. (Note the free tier does not include commercial-use rights; that unlocks on the paid plans.)
Alongside video-to-music, Sonilo offers a text-to-music mode for when you want to start from a description or steer the result — style, mood, pacing, or instruments — including segment-level controls in its v1.1 model. It also preserves the original speech in your source clip and delivers the music as a separate audio track, so you can mix the soundtrack against dialogue independently.
Sonilo runs as a web app with its own pricing and an API, and it is also available through several creative-infrastructure platforms — fal.ai, ComfyUI (as a native node), WaveSpeed, and Scenario — so developers and tools can wire video-to-music into their own pipelines. Through fal.ai it accepts videos up to about 600 seconds. Sonilo scores the video; it is not a video generator, an editor, or a publisher — getting the finished clip captioned, reframed, and posted across platforms is a separate job.
A Sonilo soundtrack solves one expensive problem — finding rights-cleared music that actually fits the cut. It does not solve the next one: one scored clip is a single upload, not a content schedule. Kompozy is the layer that turns that finished, soundtracked video into a week of published content. Bring the Sonilo export into Kompozy and it treats the clip as a source asset — burning in branded, on-style captions, reframing it to each platform's aspect ratio, and stacking hook text or overlays through HyperFrames so the silent-autoplay first second still works even before the music kicks in.
From that one scored clip, Kompozy fans out a whole content unit instead of a lone post: a Clipped Short for vertical feeds, a quote card pulled from the video's line, a caption and a text thread written in your voice through your Persona Brief, and a blog or newsletter built around the same idea. Then it schedules and publishes the set across all nine supported platforms — TikTok, Reels, YouTube Shorts, X, LinkedIn, Pinterest, Threads, Facebook, plus email and blog — from one queue. Sonilo owns the soundtrack; Kompozy owns the captions, the multi-format fan-out, the per-platform reframing, the schedule, and the publish.
Sonilo is an AI music generator for video. Instead of writing a prompt, you give it a clip and it analyzes the pacing, motion, and emotional arc to compose an original soundtrack matched to the video's exact length. It also offers a text-to-music mode and is built around commercially licensed training data.
On its paid plans, yes. Sonilo trains on professionally licensed content including Shutterstock's music catalog, with musicians compensated, and positions output as production-ready and cleared for commercial use. The free tier does not include commercial-use rights — that unlocks on the paid plans, so check your plan before monetizing a video.
Sonilo is built for scoring video specifically. Its primary mode is video-to-music — it reads your footage and composes a fitted, exact-length track with no prompt — and it leans on a licensed-music rights story. General AI-music tools usually start from a text prompt and produce standalone songs rather than soundtracks timed to a clip.

Sonilo scores the clip but does not publish it. Bring the soundtracked export into Kompozy to add branded captions, reframe it per platform, fan it into supporting posts in your voice, and schedule and publish across TikTok, Reels, YouTube Shorts, X, LinkedIn, and more from one queue.
