Vocalis AI runs entirely on-device so it's fast, private, and works offline. 49+ effect categories: Robot, Scary, Sci-Fi, Retro, Fun, Environment, more. Mix any voice effect with cinematic background sounds (rain, horror ambience, thunderstorm). What makes it different: → All processing happens locally — your voice never leaves your phone → Export as audio or video in HD quality → One-tap share → Set recordings as ringtones directly from the app Built by an indie developer. Feedback welcome!
