Frequently asked questions

What is premium usage?

Premium usage measures the computing cost of premium models. Free models use 0. Premium ones use more or less depending on the model's power. It renews every 5h and has a weekly cap.

Does Free really not need a card?

Correct. Create an account and start using it. No card, no trial — it's truly free, 25 messages per day.

What happens when premium usage runs out?

You keep using the free models without limit. Premium usage renews on its own in the next 5h window. To continue on premium right now: buy a top-up.

Can I cancel anytime?

Yes. Account → Manage subscription → cancel. You keep the plan until the end of the paid period, with no extra charges.

Pro vs Pro Max — when is it worth upgrading?

Pro Max is needed if you require Claude Fable 5, GPT-5.5 or Grok 4.3, or want automatic skills (the AI picks the agent for you). For heavy use of mid-tier models (Kimi, Qwen, Mistral), Pro is enough.

Do web search and tools cost extra?

They're included in every plan, Free included. A message with tools enabled consumes double the usage, because the AI makes several calls behind the scenes (search, read sources, answer).

How do I earn free credits?

Refer friends: in Account → Refer & earn, copy your link. Each friend who signs up gives you +200 premium credits — and they start with a +100 bonus.
