Yes. The catalog needs no payment details, every learning journey has a free opening chapter, and a free account includes small daily allowances for the AI Engineering Expert and sandboxed code runs. Pro removes the daily limits.
A free account includes 5 AI expert answers, 10 sandboxed code runs, and 20 learning actions per day. Pro removes the code and learning caps and carries a larger AI allowance; the exact daily requests and monthly model-cost budget are shown on the plan card above. You can also use your own Anthropic or OpenRouter key, and requests on your key never draw on the plan allowance.
The optional key stays in session storage for the signed-in account in that browser tab. It is sent only for an upstream request, never written to the Agentic Design database or logs, and cleared on sign-out, account switch, or session close.
Pro renews on the selected monthly or annual interval until canceled. Use the Stripe billing portal to manage or cancel; Stripe shows the effective date before confirmation.
Displayed prices exclude tax; Stripe calculates the exact amount for your country at checkout. Every first purchase carries a 14-day withdrawal right: email support within 14 days and the payment is refunded in full through the original payment method. A canceled subscription simply runs to the end of the period already paid. Details are in the Terms.
Account records, learning progress, and saved audit findings may be stored to provide the service. The Privacy Policy explains categories, purposes, retention, and your rights.
