Podcast-first editing
Built for episodes, not mixing sessions.
Traditional audio editing tools expose every track, knob, and slider because they were built for music production. HENSHU keeps the audio engineering under the hood, so podcasters can shape the story.

ALEX·00:12
Welcome to the Jungle Gym, the show where we swing through modern life from a slightly different lens, usually one with more fur and fewer spreadsheets. I'm your host, Alex, and today's guest is Dr. Maya Sterling. Maya, welcome to the podcast.
MAYA·00:34
Thanks for having me. I'm looking forward to it.
ALEX·00:40
So for those of you who don't know, Maya spent the last 15 years embedded with chimpanzees, studying how groups make decisions when nobody is officially in charge.
MAYA·01:02
That is right. The funny thing is that the patterns feel familiar pretty quickly: attention, trust, status, interruption, all the things humans bring into a meeting room.
ALEX·01:18
That is exactly where I want to start, because the meeting room comparison is the part I did not expect.

A note from the team
Tokyo · 2026
So much of the internet is increasingly being built for short, viral content. But the slower rhythm of a podcast has something that the short stuff doesn’t. There’s room to think, explain, remember, and disagree. Editing one well, though, is quite a hustle.
That’s what HENSHU is for: turning recordings into clean, listenable episodes with ease, without a studio, expensive gear, or a complicated workflow. By lowering the friction of making a good episode, we’re hoping more voices will show up. Not just people who are already established or influential, but also the ones who never had the tools, time, confidence, or access.
A phone and a story should be enough to get started. Editing shouldn’t be the wall.
Kensuke & the team
Founder · HENSHU
Made for
Podcasters who care about speed and quality.
Interview hosts, solo creators, founder-led shows. HENSHU follows the same five steps.
“I used to spend hours trying to make my interview episodes sound good, but as an inexperienced editor, the results were inconsistent and mediocre at best. HENSHU not only gives me confidence in the final sound quality, but it also makes the editing process a blast, allowing me to focus on the content itself.”

FAQ
Common questions.
How is HENSHU different from other podcast editing tools?
HENSHU is audio-only and built around episode structure. Instead of starting with a dense timeline, you arrange named sections, edit words when needed, and let HENSHU handle cleanup, music, mastering, and export.
Do I need to know audio editing?
No. If you can organize sections and edit text, you can shape an episode. HENSHU keeps the audio engineering work in the background so you do not have to learn compressors, EQ, or mastering settings.
What can I upload?
You can start with the audio you already have: phone memos, Zoom recordings, WAV, MP3, AAC, M4A, or separate host and guest tracks. HENSHU turns those files into editable episode material.
How much does AI decide for me?
The creative calls stay yours. AI can clean the sound, suggest changes, and speed up production, but you decide what gets cut, what stays, and what the episode says.
What is included in the free plan?
The free plan includes all editing features, AI cleanup, mixing, mastering, the standard BGM collection, unlimited exports, 5 hours of audio storage, and 5 hours of transcription. No credit card required.
Does HENSHU work for non-English podcasts?
Yes. HENSHU uses automatic language detection for transcription, so you can use it for Japanese and other non-English episodes. Transcription quality still depends on the language, speakers, and recording clarity.
Can I use HENSHU on my phone?
Yes. HENSHU works in mobile web, and every editing feature is available there too. You can arrange an episode, edit words, clean the sound, add music, master, and export from your phone without installing a desktop app.
Can I use my own music?
Yes. You can use tracks from the HENSHU BGM library or upload your own music for a show. For music you bring yourself, make sure you have the rights to use it in your podcast.
