FAQ

Frequently asked questions

How does the credit system work?

Each subscription tier includes a monthly credit allocation. Different AI models consume different amounts of credits based on their computational cost. Economy models (GPT-4o Mini, Gemini Flash, etc.) are completely unlimited for Pro and Team users — no credits deducted. Premium models (GPT-4o, Claude, o1) use credits from your monthly pool.

What happens when I run out of credits?

You never get locked out. Economy models remain unlimited even after premium credits are exhausted. You can continue using fast, capable models like GPT-4o Mini and Gemini 2.0 Flash with zero interruption. Credits reset monthly.

Can I cancel anytime?

Yes. Cancel anytime from your account settings. You'll retain access until the end of your current billing period, and any remaining credits can be used until then.

Do unused credits roll over?

No. Credits are allocated monthly and expire at the end of each billing cycle. This keeps pricing simple and predictable.

Is my data secure?

Yes. All data is encrypted in transit and at rest. We follow GDPR guidelines and industry-standard security practices. Your prompts and conversations are never used to train AI models. See our Privacy Policy for details.

What payment methods do you accept?

We accept all major credit cards (Visa, Mastercard, Amex, Discover) and debit cards. Payments are processed securely through our payment partner.

Do you offer refunds?

Yes. We offer a 7-day satisfaction guarantee for new subscriptions. Refunds are handled case-by-case for technical issues, billing errors, or service outages. See our Refund Policy for details.

Can I upgrade or downgrade my plan?

Yes. Upgrade anytime to access higher credit limits and team features. Downgrade at the end of your current billing cycle. Changes take effect immediately (upgrades) or at renewal (downgrades).

Do you offer team or enterprise plans?

Yes. Team plans include shared credit pools, centralized billing, and usage analytics. For enterprise needs (SSO, custom contracts, dedicated support), contact [email protected].

Which AI models are included?

All of them. You get access to 30+ models from OpenAI (GPT-4o, o1), Anthropic (Claude), Google (Gemini), xAI (Grok), Meta (Llama), Mistral, DeepSeek, and more. New models are added regularly at no extra cost.
