Spec score 8.2 #13 of 26 in AI Podcast Editing Software

What it is

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.
