Our verdict on Sonilo
Sonilo generates standalone sound effects from written prompts and scene-synced effects from uploaded video. It covers Foley, ambience, impacts, UI cues, whooshes, and transitions, making it relevant to video creators, game developers, agencies, production teams, and developers building sound generation into software. Text-to-sound-effects outputs can be configured from 0.5 to 180 seconds, while the product is available through the web and API.
The pricing structure is centered on credits and output length. Free includes 2,000 credits every 2 weeks, preview-quality exports, text-to-sound-effects generation, and personal use. Creator costs $4.99 per month when billed annually and adds 15,000 monthly credits, full-quality exports, up to 62 minutes of text-to-sound-effects generation, while retaining personal use. Pro costs $11.99 per month billed annually and adds 30,000 credits, commercial licensing, up to 125 minutes, and unlimited simultaneous tasks. Premium costs $23.99 per month billed annually, with 65,000 credits including bonus credits, up to 270 minutes, commercial licensing, and unlimited simultaneous tasks. Enterprise adds custom credits, seats, upload limits, volume credit rates, a dedicated dashboard, an account manager, and priority support.
Sonilo’s platform fit is broad for teams working across game and developer ecosystems. Integrations include Unity, Godot, Epic Games Fab, Roblox, Defold, MCP, and CLI, and the REST API supports asynchronous task polling. Outputs are available in WAV, MP3, AAC, and FLAC. Commercial rights require an eligible paid plan or qualifying API usage, so Free and Creator are better suited to personal projects. Choose Sonilo for prompt-based or video-timed SFX with flexible formats and integration options; consider another tool if reference input is central to the workflow or if commercial rights are needed on the entry plans.
