Sonilo
Sonilo is a web-based AI music and sound effect generator built specifically for video. Rather than requiring users to search a stock library or write detailed prompts, Sonilo analyzes an uploaded video edit, reading its timing, pacing, and emotional arc, and then composes an original soundtrack that matches the video's exact length. Audio is delivered as separate music and sound-effect tracks that can be exported either mixed into the finished video or as standalone files. Generation can also be driven from a text prompt alone when no video is supplied. The product targets the everyday problem of sourcing affordable, copyright-safe audio for monetized content. Its marketing cites internal usage data claiming an average 24.35% lift in video engagement versus picking a track from a music library, along with more than 5.3 million "copyright-risky" soundtracks replaced and over 700 brands using the platform. Tracks generated on eligible plans ship with a commercial license covering ads, sponsorships, and monetized channels, and the company has publicized a partnership with Shutterstock around licensed audio. Beyond the browser interface, Sonilo exposes an API through a separate platform portal and offers engine plugins distributed on the Unity Asset Store, Godot, Epic Games Fab, the Roblox Asset Store, and the Defold Asset Store, letting game developers generate licensed music and sound effects inside their projects. Integrations and partner listings also include ComfyUI, fal, WaveSpeed, Scenario, Tapnow, and BudgetPixel. A royalty-free sound effects library and a solutions page are available alongside the core generator. Pricing details are not fully published on the homepage beyond a free starting tier that provides 2,000 credits with no credit card required; commercial licensing is gated to Pro, Premium, Enterprise, and eligible API-user terms. Exact underlying model architecture, training data, and audio format specifications are not disclosed.

Problem solved
Creators need original, length-matched, copyright-safe music and sound effects for video, but stock libraries require manual track-hunting and licensing carries monetization risk. Sonilo analyzes an uploaded edit or a text prompt and automatically composes licensed audio that fits the video's duration, pacing, and emotional arc, reducing both search time and copyright exposure.
