Can I chat with AI without logging in?
Yes. On MYMI, you can chat with AI characters up to 5 times without signing up.
Open a work and select Start chatting, and a chat room opens right away without a login screen. The only works that need you to log in are adult works. This page reflects MYMI as of November 4, 2026.
How the 5 trial chats are counted
- Each AI reply you get counts as one. Switching works doesn't start a new count: all works share the same 5.
- You can see how many you have left at the top of the ⋮ menu in the upper right of the chat room.
If the trial was used on the same internet connection (the same Wi-Fi, for example) in the last 7 days, a browser or app you open for the first time may start with none left. On a connection many people share, such as office, school, or café Wi-Fi, someone else's trial can cause this too. The same can happen in a browser or app where you logged in and then logged out, or when other conditions that prevent repeated trials apply. In that case, sign up or log in to chat.
What changes when you log in
| Without logging in | After you sign up and log in | |
|---|---|---|
| Chatting with characters | Up to 5 times | You chat with Sparks. Each model uses a different number of Sparks per reply |
| Choosing a model | Not available. The trial model (currently Gemini 3.8 Flash) replies | Choose one with the ⚡ button to the left of the message box |
| User note and persona | No user note. For persona, you can only pick one from Recommended personas on the work page | Set them for each chat room |
| Adult works | Not available | Available after age confirmation (18 or older) |
| Creating works | You only see a login prompt | Create them from Create at the bottom |
| Your trial chat | When the 5 are used up, the message box locks and you're asked to sign up or log in | Moves to your new account if you sign up in the browser or app where you tried it |
You can buy Sparks, or get them once a day from Attendance Check after phone verification. See Buying Sparks. To get a new reply or edit one in a chat room, see Chatting.
If you get stuck
What happens when I've used all 5?
The message box is locked, and a notice that the trial has ended appears at the top of the chat room. Once the last reply has finished, a login window opens too. If you closed it, select Log in on the notice to open it again. After you sign up or log in, you keep chatting with Sparks. A new account starts with no Sparks, so buy some or get them from Attendance Check after phone verification first.
Do Continue and Regenerate count too?
Yes. A reply you get from the ≫ button with an empty message box, a new reply from Regenerate, and a reply the model declined each count as one. Swiping through earlier replies with ‹ › doesn't count.
Can I chat without logging in on the app too?
Yes. From the first time you open the Android or iPhone app, you can pick a work and chat without logging in. The count and the notice after you've used all 5 work the same way as on the website. But if you used the trial on the website over the same internet connection (the same Wi-Fi, for example) in the last 7 days, the app may start with none left.
Will my trial chats be kept if I sign up?
Yes, if you select a login button in the browser or app where you tried MYMI and sign up with a social account you haven't used on MYMI before. All your trial chat rooms move to the new account, and if you signed up from the login window in a chat room, you return to that chat room afterward. They don't move if you log in to an account you already have, or sign up in a different browser or app. See Sign up for how to sign up.
