Async vs Sonilo

Async is an online AI video editor where users create and edit videos through chat. It can remove filler, pauses, repetitions, bad takes, and awkward moments. Magic Dust reduces background noise and clarifies voices, while chat can generate B-roll, visuals, scenes, or music within an edit. Users can add subtitles and turn moments from longer videos into short-form clips. Async presents the workflow for ads, vlogs, explainers, podcasts, and other formats, and says it is built for creators and teams. Its browser-based remote interview feature supports up to 10 participants with separate tracks; local recording and automatic transcription are also listed. The Voice API supports text-to-speech and speech-to-text, including streaming over WebSockets. Async is available on the web and iOS, with no Android version listed. The Free plan is free and includes 10 lifetime AI credits, one hour of media upload to AI chat, exports up to 720p, and 2 GB storage. Paid pricing starts at $11.99/mo (annual).

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.
