Frequently Asked Questions

Can I try Pro features before paying?
Yes! Start a 14-day free trial with full Pro access. No credit card required until you decide to continue.
What counts as a "reasoning step"?
Each step in a protocol counts as one reasoning step. For example, the 10-step Absolute protocol uses 10 steps per complete analysis. The Quick protocol uses 5 steps.
Can I switch between weekly and monthly billing?
Absolutely! You can change your billing cycle anytime from your account settings. Changes take effect at your next billing date.
What happens if I exceed my step limit?
We'll notify you at 80% and 100% usage. When you hit the limit, you can upgrade your plan or wait for the monthly reset. We never charge overages without your consent.
Do you offer discounts for startups or students?
Yes! We offer 50% off Pro for verified startups (under 2 years, under $1M funding) and students. Contact us with proof of eligibility.
Is there a money-back guarantee?
Yes! We offer a 30-day no-questions-asked refund on annual plans. Monthly and weekly plans can be cancelled anytime.
Can I self-host ReasonKit?
The open source version (Free tier features) can be self-hosted under the MIT license. Pro/Team features require a license. Enterprise includes on-premise deployment options.
