Credits are the only currency: one reference, fully checked, costs one credit. Buy a pack when you need it, or subscribe for a monthly allowance.
Credits never expire. Bigger packs cost less per credit.
A fresh monthly allowance, billed automatically. Cancel anytime.
Each unique entry in your bibliography that we check: metadata lookup, PDF retrieval, and an identity verification that the file really is the cited work. Re-checking the same reference in the same project is free.
A claim check verifies the sentences in your text against the source. It's 1 credit per citation checked, and only fresh verdicts are charged. Re-running a check over cached work costs nothing.
Pack credits never expire. Subscription credits refresh each month with your billing cycle.
Only inside your own projects. Delete a project and everything in it goes with it.
