Introduction
Sonilo does one thing most AI music tools skip. You upload a video, Sonilo describes what is on screen, and it generates a soundtrack sized to that clip. It also makes sound effects from text prompts. As a side feature, it translates speech into 24 languages in the speaker's own voice, with optional lip sync.
The pitch is aimed at video editors, YouTubers, ad makers and small game studios who are tired of searching a stock library and then trimming a track to fit. This review covers what the product does, what the pricing page says each plan buys, how the license works, and where the evidence runs out. scored.tools did not test Sonilo hands-on. Everything below comes from Sonilo's own pages, its API docs and public listings.
Our overall score is 6.4/10. The tooling and pricing look solid on paper. Output quality is the open question, because there is almost no outside evidence on it yet.

Key Features
Video-to-music
This is the main feature. Sonilo reads the uploaded video, writes a description of it, and generates music to fit. The output matches the length of the video, so in principle there is no trimming or looping in an editor afterwards. Max upload length depends on plan: 3 minutes on Free, 8 on Pro and 30 on Premium, per the pricing page.
Sonilo's homepage claims a +24.35% engagement lift for its tracks against library music. That figure is the company's own internal data. There is no published method and no third party has checked it, so treat it as marketing.
Video-to-sound-effects and text-to-SFX
Sonilo can generate effects from the video itself or from a text prompt. The vendor's example is "footsteps on gravel." For game developers and short-form editors who otherwise pull from free SFX packs, this is the more practical half of the product.
Text-to-music
You can also prompt for music without a video. It costs far fewer credits per second than the video-based modes (details in the pricing section below), which makes it the cheaper route when you already know the mood and length you need.
Video translation and lip sync
Sonilo translates speech into 24 languages in the speaker's voice, with optional lip sync, and keeps the music and effects tracks intact. It accepts .srt and .vtt subtitle files as input. Translation is not available on Free. Pro gets 800 seconds per language per month and Premium gets 2,000, per the pricing page. This is a full dubbing feature inside a music product, and it competes with dedicated dubbing tools rather than with the music generators listed below.
API and library
The platform docs at platform.sonilo.com describe API keys, a streaming music endpoint, async sound-effect endpoints and timeline placement. The docs offer 12 free trial calls. There is no official SDK in multiple languages, so expect to write your own HTTP client. Sonilo also has a royalty-free music and sound effects library, and partner listings on Unity Asset Store, Godot, Epic Games Fab and Roblox Asset Store.

What credits actually buy
Video-to-music and video-to-SFX cost 18 credits per output second. Text-to-music costs 5 and text-to-SFX costs 4. Every generation is billed at a 15-second minimum and a 200-credit minimum charge. So a 15-second video soundtrack costs 270 credits, while any short text generation costs at least 200.
Working from Sonilo's own figure of 148 clips on Pro, that is about 37 minutes of video-scored audio a month. Premium's 370 clips come to roughly 92 minutes. Credits do not roll over, and every regeneration you run while hunting for a usable take comes out of the same pool. A creator who scores two or three short videos a week will fit inside Pro. Someone scoring long-form content, or rerolling a lot, will hit the ceiling and need Premium or top-up credits.
The free tier is a demo
Free gives 2,000 credits every two weeks, which is about seven 15-second soundtracks. Exports are preview quality only, and the license is personal and non-commercial with required attribution. You can judge whether the music fits your footage. You cannot ship it in a client video, an ad or a monetized channel.
Licensing
Pro covers ads, branded content, client work, monetized channels and indie games, with no attribution required. Premium extends that to film, TV, broadcast and studio games. Paid plans get a downloadable license certificate, which helps when a client or platform asks for proof. Sonilo states that its model is trained only on licensed catalogs. The pricing page also says plainly that commercial rights do not remove every copyright, platform, client or broadcast review, and tells users to check the current Terms before publishing. That caveat is honest, and you should take it at face value.
Pros and Cons
Pros
- Music is generated from the video itself and sized to its length, so there is no manual trimming.
- Pricing is published, and Pro at $14.99 a month is cheap for a commercial audio license.
- Paid plans include a downloadable license certificate and a clear split between Pro and Premium rights.
- Free start with no credit card.
- Documented API plus listings on Unity Asset Store, Godot, Epic Games Fab and Roblox Asset Store, which suits game developers.
Cons
- No independent reviews of output quality. The Product Hunt and Godot listings show none, and the +24.35% engagement figure is Sonilo's internal data.
- Free exports are preview quality and non-commercial, so you cannot ship anything without paying.
- Video-based generation costs 18 credits a second, more than three times text-to-music, and credits expire each cycle.
- The 8-minute upload cap on Pro rules out scoring long videos in one pass.
- Film, TV and broadcast use needs Premium.
- Translation and lip sync widen the scope, which may pull focus from music quality.
- No official SDKs for the API.
Who Is It For
The best fit is a solo editor or small team producing short videos (ads, social clips, YouTube intros, product demos) who currently spends time searching a stock library and cutting tracks to length. For them, Pro at $14.99 covers the commercial use they need and removes the trimming step.
Indie game developers are the second good fit. The engine store listings, the async SFX endpoint and the indie games clause in the Pro license all point at that audience.
Sonilo is a weaker fit if you need music you have heard and approved before you pay, which a stock library like Epidemic Sound gives you. It also suits you less if you mostly need full-length tracks without a video, where prompt-driven generators such as SOUNDRAW, Soundful, Beatoven.ai and Mubert are the obvious comparisons. Broadcast and film work requires Premium at minimum, and anyone doing that work should read the Terms with a lawyer first.
Verdict
Sonilo earns a 6.4/10. The product idea is sound, the setup is easy, the API is documented and the pricing is public and reasonable. The weak point is evidence. Output quality scores 4/10 because the only proof it sounds good comes from Sonilo itself.
Our recommendation: start on Free, run your own footage through it, and listen to the previews before you pay. If the tracks fit, Pro at $14.99 a month (with the $5.99 first month) is a low-risk way to get commercially licensed, length-matched audio for short videos. Do not commit client deliverables or broadcast work to it until you have checked sample output and the current Terms yourself.
