One corpus. Four levels of use.
One credit is one answered question. A question the verification gate declines to answer costs nothing. Every plan reaches the whole of Title 21 and every feature - only the allowance differs. Each plan includes one seat; additional seats are $20 each per month on every plan. A credit allowance is granted monthly, and unused credits carry forward. Annual subscription provides twelve months at the cost of ten. Terms may be amended or discontinued at any point.
