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).
Pixazo AI SFX Generator
Pixazo AI SFX Generator creates short sound effects from text prompts and can also match audio to an uploaded video clip. Text-to-audio uses Mirelo SFX, while video-to-audio uses MMAudio. It can produce one-shot effects, foley, game and UI sounds, and loopable ambiences, with results downloadable as WAV files. Generation and downloads happen in a browser; no separate audio software is required.
The Free plan costs nothing and gives 100 bonus credits during a 7-day trial. Those credits lapse after the trial, which has no API access or commercial rights. Pro Monthly is 37.50 BRL a month, and Pro Yearly is 299 BRL a year; both list 300 credits per month and commercial rights. API billing is pay per call in USD, with a free tier and a separate account from Pro. Pixazo describes RESTful APIs for app and workflow integration. The tool is intended for video editors, game developers, motion and UI designers, podcasters, and app makers. It does not make full songs or offer multi-track mixing, and specific or branded sounds may need prompt refinements. Commercial use depends on plan terms.
