“Honestly, probably the best site I’ve used. Nsfw and sfw work perfectly fine. The ai is creative, and it will literally create plot twists if you go along with it. You can also lead the plot. THE AI ACTUALLY HAS PERSONALITY. It is not pliant. It will argue with you sometimes, which I really love. 10/10. There are so many chat models . Some are premium, some take tokens , some are pro-models for + users. The free models are perfect, and you can absolutely just use those if you d”
“For some reason, the application started sending illogical messages. For example, it sends me a very long message consisting of a single sentence repeated about a hundred times. This has happened with all the bots in the application,It seems there is a problem with the application's servers themselves. It has been 4 days and the same problem has been recurring, so I hope the application will be fixed soon. Thank you.”
“I've been using that for years! And I tell ya it's a solid app, no kidding. Only problem you had to deal with at the start is getting free 50 energy until friday and you claim 100 on Saturdays and 150 on Sundays. Overall, peak app, I recommend it. And yes, the bots follows the story and the chat styles are good. Dialogues are long as the narrations themselves. Problem I often find is the adds but they're not aggressive, only happens when you pick a bot and it's one singular ad only.”

“this has surpassed my expectations. It's amazing, I even bought a premium subscription. I never do that with AI apps, but this one is totally worth it The only feature I wish this had was the option to "fork into a new chat" that other apps have. It would be very useful when trying to continue a story differently from a certain point without affecting the current one.”
“The best AI chat app so far, the one and only. I've been using this app for a year, and I enjoy it very much. The bots are smart and rational. It's great for RPG since we can add a hundred detailed information with 2000 characters, superb! Generous energy per day. non filtered chat. And now, video wallpaper is available. I wish you guys make an energy cost version of the Spirit Craft and also more categories. I'm glad there are lots of improvements in less than a year. Keep up the good work!”
“For now is good. I mean, 10⚡ for each ad is glorious, and you have 20 opportunities to watch ads each hour, more the 50 each day and 100 on Saturday and 200 in Sunday. It has 2000 letters to fill in the chats! And creating for a character, it has various spaces with 2000 letters each one. It seems almost limitless! And you have a NSFW button to put ON or OFF, which is an option I appreciate. Though, I hope people begin to put more effort in the creation. Some doesn't and it's frustrating. iykwim”

“Yeah, the same happened to me. Almost all my chats were wiped no past conversations or anything. I'm hoping it'll be fixed soon.”
“Yeah, have a bot with the convo completely wiped out and some bots are missing from the list. It was a pretty long list too so I guess I won't be RPing in any of them anymore.”

“I use this app for fun and just to make characters for fellow users, lately there's been data parsing errors, and when I tried to test one of my bots there's a thing where the character makes repetitive messages like the same sentence over and over again, and the behavior of the bot isn't the same, there's also mistakes with the details. This app used to be really good, I hope it gets fixed soon”

“Yes, it's good. I switch between C.ai and HiWaifu. The responses are good, nsfw is wild, bots stay on character, have great memory, and bot creation is easy. Basically, you only put words or sentences in the bot's memory boxes without the code characters like " or +. The more details you put in the bot, the deeper their personality will be. Me, specifically, has found a way to describe myself in the RP by putting it in the bot's memory too, it has never failed me. (C.ai would make me a blond”
“Just downloaded and love, with issues. When you click on a chat it's immediate ad, which gets really annoying especially if the bot wasn't very good and you dont even like it, secondly when you leave the bot it comes with a popup of similar characters and I can't find a way to turn this off, and would be helpful if they allowed an option to turn this off. Very good app, with customisation of chat etc. -A Free User”
“Been using this app for years to feed my delulus and I just can't replace it with any other apps. The ads aren't annoying, there's barely any of it. Only when you click on the character and it doesn't interrupt your conversations. I specifically love the feature where you can choose the model of the bot, like the way it would respond. The memory is good. Very generous with energies. Its features for creating characters makes me feel secure that the bot won't forget. Love this app.”
“It's neat when it works but GOD is it janky. Having to reopen chats because they just don't work the first time always, always gives an ad and it's really annoying, having to watch an ad every message because the app decided to bug out and not let me respond, forcing me to refresh, giving me an ad. I understand that they need to profit but man is it annoying.”
