Otto turns your voice into something worth sharing. Record, flip it backwards, drop an effect on it, then send it out as a video. The name reads the same backwards, and so does everything you make here.
SHARE IT AS A VIDEO
Audio files go nowhere on social apps. Otto renders your recording as a vertical video with an animated waveform and your own caption, sized for TikTok, Reels and Shorts. Save it to Photos or share it straight from the app.
ELEVEN VOICE EFFECTS
Reverse is where it started. Now you also get Slowed for that late night sound, Chipmunk, Demon, Whisper, Robot, Phone, Megaphone, Underwater, Glitch and Cave. Record once and try every one of them on the same take.
ASMR BACKGROUNDS
Layer a soft sound under your voice: rain, white noise, keyboard clicks, tapping, brushing, paper crinkle, fireplace, wind or a slow heartbeat. Set how much of it you want with one slider. Pair it with Whisper and you have an ASMR clip in seconds.
THE BACKWARDS CHALLENGE
Read a phrase out loud. Otto plays it backwards. Now try to copy that sound. Otto reverses your attempt and puts it next to the original, then scores how close you got. Bring a friend, it gets worse for both of you.
WHAT IT IS GOOD FOR
Reverse singing and say it backwards clips
Funny voice messages your friends will replay
ASMR and whisper content with a background you choose
Sound effects for videos and music
Finding out what a laugh or a sneeze sounds like in reverse
FREE AND PRO
Free gives you recording, four effects, three ASMR backgrounds, full length playback with nothing cut short, the challenge, and video export with a small watermark.
Pro removes the watermark and unlocks the remaining effects and ASMR backgrounds. That is the whole difference.
Everything runs on your device. No account, no sign up, and it works with no connection.
