Billing FAQ
When am I charged?+
You are charged on the day you subscribe, then on the same date each month. Your word count resets automatically on that date.
Can I switch plans?+
Yes. Upgrade or downgrade anytime from your account page. Upgrades are instant. Downgrades take effect at the next billing cycle.
Do unused words roll over?+
No — word counts reset each billing cycle. This keeps pricing fair and costs predictable for everyone.
How does PenSmith humanise text?+
PenSmith uses advanced natural language processing to rewrite text at a structural level — varying sentence rhythm, word choice, burstiness and perplexity. This is what AI detectors actually measure, so targeting it directly produces genuinely undetectable results.
Is there a money-back guarantee?+
Yes. If you are unsatisfied within 7 days of your first subscription charge, contact us at hello@pensmith.ai for a full refund.
