How can I help?

We reply by email or in Telegram within one to three working days. Urgent matters — in the bot @arkheon_ai_bot.

FAQ

Credits were charged but there is no answer

Only the actual cost of the answer is charged; if the model did not answer, the hold returns by itself within a minute. If the balance did not come back, write to us with the time and the model.

The request was refused with a note about the terms

The automatic check fired. The rules and consequences are described on the page the terms of use. A wrong refusal can be contested through an appeal — your moderation records are visible there.

The payment went through but the credits did not arrive

A YooKassa payment is credited within a minute, App Store and Google Play purchases right after verification. If more than 10 minutes have passed, write to us with the date, the amount and the payment method.

One account on the site, in Telegram and in the app?

Yes. Balance, conversations and settings are shared. Telegram can be linked to the site account in your account; sign in to the app via Telegram or by email.

Write to support

If you are blocked and cannot sign in, that is fine: give the account's email or Telegram and we will find it ourselves.
