Pricing FAQ
Do I have to install anything?
No. Polyz runs in your browser. Sign up and you can be writing in the Web Studio a minute later. There's also a desktop app for macOS, Windows, and Linux, which adds offline-first local projects and print-engine PDF export. Same account, and cloud projects sync between the two automatically.
How does the trial work?
Click Start free trial, create an account, and add a card on Stripe Checkout. You won't be charged for 7 days. Cancel before day 7 (from inside the app or via the Stripe customer portal email link) and you owe nothing. After day 7 the card is charged $25.99/month, and the same account works on every device.
How many courses can I create?
Pro includes up to 2 new personal courses every month, and each one is a full multi-unit syllabus with lessons, graded practice, and an AI tutor, sized to take weeks to work through. Courses you've already built stay on your dashboard and don't count against a later month. Before subscribing you can try the whole flow free: the diagnostic, your generated course, and the entire first lesson cost nothing.
Is there a limit on AI usage?
Yes. Every AI call (chat, the writing agent, authoring, coaching, grading) draws from a generous monthly quota that's sized for typical heavy use. Most users never hit it. If you do, AI features pause until your subscription renews; everything else in the app keeps working. You can also buy a one-time top-up pack from inside the app if you want to keep going mid-cycle.
What about AI usage during the trial?
Real LLM tokens cost real money, so the trial includes a reduced AI quota (enough to fully evaluate the AI features before you commit). The moment your first payment clears, you switch to the full monthly quota, which resets on each renewal.
Can I cancel anytime?
Yes. During the 7-day trial, cancel from your account settings or via the Stripe customer portal and you're never charged. After the trial, cancellation stops the next renewal, and you keep access through the end of the period you paid for.
What happens to my data if I cancel?
Your work stays yours and your exports are never paywalled. If you cancel, you keep read and export access to everything you've written. Writing, AI features, and cloud sync resume when you resubscribe.
Is there a refund policy?
If you're not satisfied, email us within 7 days of purchase for a full refund. After that, prorated refunds are not automatic, but Stripe lets you keep access until the period ends.
Write your next chapter with a coach in the room.
Seven days free, every feature unlocked, writing in your browser a minute from now. If it doesn't make you a better writer, cancel and pay nothing.
