What devices are supported? ＋
KakuCut supports iPhone running iOS 17 or later. iOS 26 enables the primary on-device SpeechAnalyzer transcription path.
Can I edit more than one video? ＋
Yes. The current multi-video workflow supports up to ten ordered videos in one project.
Is KakuCut free? Does it add a watermark? ＋
