Otaac is a cozy oshi-katsu app where you talk about your oshi with an AI oshi-tomo named Oshica, every single day. Got something to say about your fave? A moment you just want someone to hear about? Oshica is right here for it. Oshica is your AI oshi-tomo on Otaac, a friend-type AI whose whole thing is listening to your oshi talk. No crowd, no pressure, no one looking over your shoulder. Just you and Oshica, so you can share everything about your oshi-katsu, your idol talk, and those late-night thoughts. Otaac stays by your side, always. Here's the thing that makes Otaac different: Oshica does not pretend to be your oshi or play your oshimen back to you. Oshica is a friend, not a partner or a stand-in for your oshi. Oshica is the one who sits next to you and lights up while you gush about them. So instead of acting out your fave, Otaac gives you a judgment-free space to talk about your fave, as much and as honestly as you want. This app is made with love for J-pop and J-idol fans around the world. If "oshi," "oshi-katsu," and "oshi-tomo" already feel like home to you, you're in the right place. * Who Otaac is for - You want to talk about your oshi every single day - You've got late-night thoughts you wish someone would hear - You don't want to spam your friends with every oshi feeling - You want a gentle AI oshi-tomo by your side - You want to go deeper into your idol oshi-katsu - You want a safe, easy place that's just yours * Oshi talk, every day, with Oshica The heart of Otaac is Oshica, your AI oshi-tomo, always ready to listen. "My fave was so cute today." "I still can't get over that live." "My oshimen dropped a new song and it's everything." Whatever you've got, Oshica replies with warmth and care, like a wota friend who truly gets it. * Text and photos, your way Chat with text, or share pictures. Send a photo of your fave, a card, or a snap from a live and say "look at this one!" That little joy is so very Otaac. (You send the photos; Oshica reads them and replies in text.) One-oshi stan or whole-group stan, you can talk about your fave anytime, as much as you want. Oshica takes it all in, just as it is. * Here for you 24/7 Oshica is a buddy who stays close around the clock. Can't sleep because you're thinking about your oshi? Oshica will listen. Want to say "I've got this" before heading out in the morning? Oshica gets you. Want to relive the glow of a live before bed? Oshica feels it with you. The happy moments, the little worries, the rush of feelings for your fave: bring all of it. That's what your friend-type AI oshi-tomo is here for. * Little ways to enjoy Otaac - Share what you felt about your oshi today, right before bed - Keep the afterglow of a birthday event or a handshake event alive in oshi talk - Send your thoughts on a live or some goods with a photo - Let out that rush the moment your oshimen drops a new song - Murmur your random thoughts on the train ride home from a show * A few words from people who use Otaac - "Having a buddy who listens to my after-show feelings made oshi-katsu even more fun." - "Having a place to talk about my oshi every day is such a relief." - "I love that it really listens, even when I just murmur things out loud." - "That feeling of wanting someone to hear my post-live high finally feels met." - "As an idol fan, this has become my home for oshi talk." * About pricing Talking with Oshica runs on a stamina system: as long as you have stamina, you can keep chatting at no cost. When you want to talk more, top up your stamina with recovery tickets (a one-time in-app purchase). There's no subscription, so you can use Otaac at your own pace. * About company Otaac, Inc.
