Frequently asked questions
How does HippoKit credit pricing work?
You get a fixed credit pool every month. Formats cost different credits: flashcards 1, quiz 2, ebook 12, audio 6, slides 20, or a 5-format kit at 34 (17% bundle discount). Unused plan credits roll over to the next cycle, up to one month's worth. Top-up credits never expire. Your bill is fixed; you never get an overage charge.
What's included in HippoKit's free tier?
60 credits per month — about 1 full 5-format study kit, or 60 flashcard sets, or 30 quizzes. No credit card required.
What file types can HippoKit turn into study materials?
HippoKit accepts PDF, Word (.docx), and PowerPoint (.pptx) as a source — alongside a plain typed topic. Upload an existing slide deck or training doc and HippoKit turns it into flashcards, a quiz, an ebook, an audience-themed slide deck, and an AI-narrated audio lesson. The Free tier accepts PDF; Word and PowerPoint uploads are on paid plans.
How many study kits can I make with HippoKit Plus?
HippoKit Plus is $12.99/mo ($10.79/mo billed annually) for 150 credits per month — about 4 full 5-format kits, or 150 flashcard sets, or 75 quizzes, or any mix totaling 150 credits.
How many study kits can I make with HippoKit Premium?
HippoKit Premium is $34.99/mo ($28.99/mo billed annually) for 500 credits per month — about 14 full 5-format kits per month, plus priority generation.
What is HippoKit Studio?
HippoKit Studio is $99.00/mo ($81.99/mo billed annually) for 1500 credits per month, premium-model opt-in (Gemini 3 Pro / Claude Opus on demand), priority generation, and bulk export tools. Click Upgrade to Studio on the pricing page to start.
What is HippoKit Enterprise?
HippoKit Enterprise is the bespoke sales-led tier — SSO, admin dashboard with org-wide usage analytics, SCORM/LMS export, dedicated CSM, and custom contracts with invoicing. Pricing is custom; click Talk to us on the Enterprise card to start a conversation.
What's HippoKit's annual discount?
17% off when you pay annually. Plus drops to $10.79/mo (billed $129.48/yr); Premium drops to $28.99/mo (billed $347.88/yr); Studio drops to $81.99/mo (billed $983.88/yr). Enterprise pricing is custom — annual billing is negotiated per contract.
Do unused credits roll over?
Yes. Unused plan credits roll over to your next cycle, up to one month's worth — so a light month is never wasted. Credits refresh on your billing date each month (not the 1st), and separately-purchased top-up credits never expire at all.
Why not an unlimited plan?
Every AI tool has cost-to-serve limits. Some hide them in fine print; we put the limit on the front of the page. You always know exactly what you have left.
What's your refund policy?
Full refund within 7 days of any charge, one per customer, no questions asked. Issue the refund yourself from Settings → Request a refund.
What if I cannot predict my usage?
Use the cost calculator at /tools/ai-study-kit-cost-calculator to estimate your monthly need. You can change tier anytime — upgrades take effect immediately, downgrades at the next billing cycle.
Does my plan include AI assistant integrations?
Yes — all paid plans include MCP access. Connect HippoKit to Claude Desktop, ChatGPT, Gemini, or Cursor, and your existing monthly credit pool covers both web and assistant generation. Anonymous demo is also available with a $200/month company-wide ceiling.
7-day money-back guarantee
Cancel within 7 days of any charge for a full refund — one per customer, no questions asked. Manage refunds and cancellations from Settings.
