Every plan includes a monthly word allowance. Usage is metered by actual words processed, not by how many times you click Humanize — a 3-word tweak and a 3,000-word chapter aren't charged the same, because they don't cost the same.
Your monthly allowance resets every billing date
Starter includes 37,500 words/month, Pro includes 125,000, Max includes 300,000 — on your billing date, it refills completely. Unused monthly words don't carry over.
Launch offer: 5,000 bonus words on signup
A one-time bonus for signing up during launch, available on every tier. It goes into your top-up balance below, so there's no deadline to use it by — but like any top-up words, it's spent as you run jobs, not an unlimited well.
How the two balances are used
Every Humanize or Check AI Score run draws from your monthly allowance first. Only once that's exhausted does it start drawing from your top-up balance (bonus words and any purchased credits) instead.
If you run out of both before your reset date
You have two options: wait for next month's reset, or buy a credit top-up to keep going right away. Nothing is throttled or degraded — you simply won't be able to run new jobs until one of those happens.
Credit top-up: $5 for 5,000 extra words
One simple size, no sliding scale to figure out. Goes straight into your top-up balance alongside any launch bonus. No deadline to use it and no monthly reset — it just sits there until you spend it on a job.
