Generate sound effects timed to visible action in a video instead of searching for a stock clip and aligning it manually. The browser workflow avoids mandatory API setup, but the newer product needs testing against your own footage. Commercial work requires Pro or eligible API terms; confirm current subscription or usage rates before committing.

Create sound-effect candidates from a written prompt for game-audio work. Browser creation and documented API paths support experimentation and integration, but the limited track record calls for genre-specific listening review. Free and Creator are non-commercial, so released commercial projects need Pro or eligible API terms with current rates checked.

Overview
Not yet reviewedProduct quality is assessed from original evidence. How reviews work.
Sonilo generates realistic sound effects and music from a written prompt or directly from a video clip, syncing generated audio to on-screen action instead of leaving creators to search stock-sound libraries for a close-enough match. Point it at a video and it can analyze the visible action and generate sound effects timed to what's happening on screen, or skip the video entirely and generate an effect or a music track from a text description alone. Sonilo is available through its own browser-based upload and create workflow at sonilo.com, on subscription plans, and via its own documented API; it is also available through fal as an API integration partner for teams already using fal for other generative media.
Free and Creator plans are for personal, non-commercial use; commercial rights are available on the Pro plan or under eligible API terms. Sonilo fits video editors, game developers, and content creators who need sound effects that actually match footage timing without digging through stock libraries or hiring a sound designer for every project, as well as anyone who also wants a generated music track.

- YesSonilo's canonical domain is confirmed as sonilo.com, not the sonilo.ai used in the catalog listing, though both point to the same product. Its own privacy policy explicitly states that by using the service you grant Sonilo a license to use uploaded videos, prompts, outputs, ratings, edits, and usage data for AI model training, fine-tuning, and general improvement, carving out two exceptions: audio tracks in uploaded videos are not currently analyzed for this purpose, and Google or YouTube integration data is never used for AI training.

Our Take
Video creators doing post-production who need sound timed to what's actually happening in a shot, footsteps landing, objects hitting surfaces, environmental cues, are a core use case, alongside creators who also want a generated music track. It's available directly through sonilo.com with its own browser workflow, subscription plans, and documented API, as well as through fal for teams already in that ecosystem. Free and Creator plans are for personal, non-commercial use; commercial rights require the Pro plan or eligible API terms. It's still a newer product, so set realistic expectations and test directly against your own footage before committing.
