Async vs Henshu

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).

HENSHU is an audio-only podcast editor for arranging episodes into named sections and editing their audio through text. Users can organize blocks, then trim, cut, or improve each one independently. AI tools reduce noise, level volume, and master audio; the site says there is no need to adjust EQ or compression. Automatic transcription detects language and supports Japanese and other non-English episodes, though results depend on language, speakers, and recording clarity. The music library has roughly 200 podcast-ready tracks, with looping, fades, and ducking under speech. Inputs include phone memos, Zoom recordings, WAV, MP3, AAC, M4A, and separate host and guest tracks. Users can download mastered episodes and generate or copy show notes and chapters for their hosting destination; direct publishing integrations are not described. HENSHU works on Android, iOS, and the web, including mobile web. The Free plan is free; Standard costs $15 a month, billed monthly.
