Sonilo generates music and sound effects intended to follow a video's pacing, mood and scene changes. Users can upload MP4 or MOV video, or describe the desired audio in text. Sonilo processes the visuals while leaving the original audio available to keep, adjust, replace or layer. It generates several variations by default and accepts an optional prompt to guide style. The service also supports speech translation, video re-voicing, lip-sync re-rendering and SRT or VTT subtitles. Its API covers music and sound-effects generation, audio ducking, task polling and account usage; plugins are listed for Adobe Premiere Pro, Unity, Godot, Epic Games Fab, Roblox Studio and Defold. Free provides 2,000 credits every two weeks, with preview-quality exports and videos up to 3 minutes. Pro is $11.99 a month, billed yearly as $143.88, and Premium is $23.99 a month, billed yearly as $287.88. Commercial use is limited to specified paid plans and eligible API users. Sonilo says uploaded videos, prompts, outputs and related data may be used for training and product improvement by default.
