A 500-word assignment should not require a monthly subscription
Everyday coursework was never hard to rewrite - it was just never worth a full month of subscription. HumanPen bills on the words it actually rewrites, so a short assignment costs cents, and unused credits carry over indefinitely.

1,000 words costs 100 credits — you are only charged for the words actually rewritten

The real cost problem with everyday coursework
Assignments and theses are different spending patterns. A thesis is two or three pieces a semester at thousands of words each. Coursework is several pieces a week at a few hundred words each.
Subscriptions serve the second case badly. A $12-18 monthly plan against three 500-word assignments means paying well over ten dollars for 1,500 words - and paying again next month if you forget to cancel. That is how people end up with a service in their subscription list they use twice a year.
Metered billing runs differently: a 500-word assignment costs 50 credits, roughly $0.50. Three of them is $1.50, and then it stops. Credits in your account do not expire, so the next time you need it, it is there. The 100 credits you get at signup already cover two short assignments.
There is also a specific sub-case worth naming: discussion-board posts. Short, conversational, meant to read like something you typed off the cuff - which is exactly where AI phrasing stands out most. Even sentence lengths and a tidy three-part argument in every reply read less like a forum and more like a template.
Frequently asked questions
What does one assignment actually cost?
100 credits per 1,000 words (about $1), billed only on words actually rewritten. A 500-word assignment is about 50 credits, roughly $0.50. Signup gives you 100 credits - two short assignments.
Do I need a subscription? Do credits expire?
No subscription and no monthly fee. Credits are bought once and never expire. Failed or cancelled jobs are not charged.
Can I process several assignments at once?
Upload each as a separate file - up to three jobs run concurrently, and all results collect in History. Bundling several assignments into a single job is not supported today.
Can it handle something as short as a discussion post?
Yes, put it in a Word file and upload. Note the 10-credit minimum per job, so processing a very short text under 100 words on its own is poor value - put several posts in one document instead.
My assignment has code blocks, formulas, and tables. Will those break?
No. Formulas, figures, and table structures never enter the text rewrite. But if code is written as ordinary body text, use "specify content" to scope the rewrite to the prose and leave the code out.
Can it handle a Chinese-language assignment?
Not yet - the engine is currently tuned for English.
