What Henshu is
HENSHU is an audio-only podcast editor for arranging episodes into named sections and editing audio through text. Users can organize audio blocks, then trim, cut, or improve them independently. Its AI tools reduce noise, level volume, and master audio; the site says users need not adjust EQ or compression. Transcription uses automatic language detection and supports Japanese and other non-English episodes, though quality depends on language, speakers, and recording clarity. The product describes roughly 200 podcast-ready tracks cleared for podcast use, with looping, fades, and music ducking under speech. Inputs include phone memos, Zoom recordings, WAV, MP3, AAC, M4A, and separate host and guest tracks. Users can download mastered audio and generate or copy show notes and chapters for publishing wherever they host their show; direct publishing integrations are not described. HENSHU is available on Android, iOS, and the web, including mobile web without a desktop app. The Free plan is free; Standard is $15 a month, billed monthly.
