Record With Your Script on Screen
Each project can store a title, script, and notes. During recording, your script stays on screen, so you do not need to switch between apps. You can also adjust the script display to make it easier to read.
Manage Multiple Takes
Record several takes, listen back, compare them, and choose the one you want to use. This makes it easier to keep track of which recording belongs to which script.
Prepare Audio for Short Videos
Koetsuku-cho provides simple audio controls for creators who want to use their own voice in videos. You can adjust:
- Pitch
- Speaking speed
- Volume
- Silence trimming
- Noise reduction
The app also includes presets designed for common narration styles, such as short videos, bright voice, calm voice, commentary, and news-style narration.
Export Through the iOS Share Sheet
When your audio is ready, you can export it through the iOS share sheet. You can save it to Files, send it with AirDrop, or pass it to video editing apps and other destinations supported by iOS.
On-Device Storage
Your recordings, scripts, project information, notes, and settings are saved on your device. Koetsuku-cho does not require login or account registration, and it does not upload your audio or scripts to an external server.
No AI Voice Generation or Voice Cloning
Koetsuku-cho is not an AI voice generation app. It does not create synthetic voices, clone voices, copy another person's voice, or imitate celebrities, creators, voice actors, or public figures.
Record your own voice, prepare it for video, and export it when you are ready.
