In their own words
Async
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).
Creen
Creen generates sound effects by synthesizing audio from written prompts rather than retrieving clips from a stock library. Its sound workspace also supports video-aware audio, ambience beds, and AI music generation. Prompts can specify material, distance, room size, microphone perspective, intensity, and mood. Each generation returns multiple takes to audition and regenerate; users can export audio and save favorites in reusable sets. The workspace includes more than 40 image, video, and audio models. Its sound workflow is prompt-first: descriptive language and model choice are the main ways to steer results, rather than reference-audio uploads. Creen says users own generated sound effects and may use them in social content, video, games, podcasts, and advertising. It lists video editors, filmmakers, indie game developers, short-form creators, podcasters, motion designers, teachers, students, and hobbyists as audiences. Creen is available on Android, iOS, and the web. A free plan is available, and the pricing note says paid plans start at $10/mo. Annual plan listings include PLUS at $6 a month, PRO at $17.40 a month, MAX at $29.40 a month, and ULTRA at $107.40 a month.
