SayCut turns talking videos you filmed yourself into a first edit with AI captions and cuts. Then you finish it by asking in chat: "Make the captions bigger", "Shorten the long pauses", "Keep this scene as it is". Every change shows up as a before → after card you can undo on its own, so the AI does the busywork and you make the call. Filler words removed, music ducked under your voice. Export for Reels, Shorts and TikTok. Works in English, Korean and Japanese.
