Common Questions
Everything you need to know about Shannon AI pricing and plans
What are daily tokens?
Tokens are the unit of AI processing. Each message you send and receive consumes tokens based on length. Daily tokens reset at midnight UTC. On average, 1,000 tokens equals about 750 words of conversation.
Can I upgrade or downgrade anytime?
Yes, you can change your plan at any time. Upgrades take effect immediately with prorated billing, and downgrades apply at the end of your billing cycle. No lock-in contracts.
What happens if I run out of tokens?
When you exhaust your daily allocation, you can wait for the next reset, purchase token add-ons, or upgrade your plan for more tokens. We'll notify you when you're running low.
Do you offer refunds?
We offer a 14-day money-back guarantee for new subscriptions. If you're not satisfied, contact support@shannon-ai.com for a full refund (no questions asked).
What payment methods do you accept?
We accept all major credit cards (Visa, Mastercard, Amex, Discover) through Stripe, as well as cryptocurrency (Bitcoin, Litecoin, Dogecoin). Enterprise customers can also pay via invoice with NET-30 terms.
Is my data secure?
Absolutely. All data is encrypted in transit (TLS 1.3) and at rest (AES-256). We're SOC 2 Type II compliant. Enterprise customers can opt for dedicated infrastructure and data isolation.
Can I use Shannon AI for production security testing?
Yes! Shannon AI is designed for professional red-team testing. The Pro plan includes reproducible test suites and audit-ready reporting for production environments.
