Honest FAQ
What counts as a check? One claim, one question, one citation, one receipt.
Essay reviews are metered separately, so a heavy essay week never eats your checks. How big can a review be? Pro takes drafts in 5,000-word parts and batches up
to 20 in one run, which is a whole thesis. No daily cap: the month's 1,000 citations are
yours to spend in one sitting if the deadline demands it. What's the annual deal? Twelve months for the price of ten. Two months free.
Bro is $99 a year ($8.25/mo), Pro is $299 a year ($24.92/mo). Why does Pro cost more? It unlocks the side-panel workspace: whole-draft
review, the argument critique, the analytical lens, and a searchable claim library.
and digs deeper on every check. Cancel? Any time, from your Stripe receipt email. No retention maze.
Every receipt you share can pay for your subscription: when someone subscribes through
your link, you earn monthly for as long as they stay. Receipt dividends →
