Can I turn a PDF into flashcards and a quiz?

Yes. Upload a PDF and HippoKit reads it, then generates flashcards, a scored quiz, a formatted ebook, an audience-themed slide deck, and an AI-narrated audio lesson in one pass — each exportable. PDF upload is available on every plan, including Free.

Does HippoKit work with Word documents and PowerPoint files?

Yes. HippoKit accepts Word (.docx) and PowerPoint (.pptx) uploads alongside PDFs, plain images, and a typed topic. Drop in an existing training doc or slide deck and it becomes the same five study formats. Word, PowerPoint, and image uploads are on paid plans; PDF is on Free.

What can I use as a source?

A typed topic, or an uploaded document — PDF, Word (.docx), PowerPoint (.pptx), or an image. HippoKit turns any one of those into flashcards, a quiz, an ebook, an audience-themed slide deck, and an audio lesson, generated together in a single step.

How We Process Uploaded Files

When you upload a file, we use AI sub-processors to read it and generate your study content. Your uploaded files and the content derived from them are processed by Google Cloud / Vertex AI (Gemini for reading and generation, and Cloud Vision for image screening) and, as a fallback during generation, by Anthropic (Claude). These providers process your content under enterprise API terms and, per those terms, do not use your content to train their public or foundation models.

Shared Courses & Learner Data

HippoKit lets a user publish a kit they own as a tracked, shareable course. If you open such a course and enroll, we collect the email address you provide and your progress in the course — which formats you start and complete, and quiz scores recorded as numbers only. We do not store your quiz answers or any free text you enter while studying.

The HippoKit user who shared the course (the “course owner”) can see your email address and your progress so they can track completion. For a shared course, that owner acts as an independent data controller for the learner data they collect, and is responsible for using it lawfully. HippoKit acts as the processor that hosts and secures that data on their behalf.

Your email is used only to identify your enrollment; internally we also keep a one-way hash of it so we can recognize a returning learner without exposing the address. Your email is never shown to other learners and never appears on any public page, in our sitemap, or in search results — tracked course pages are excluded from indexing.

You have the right to erasure. On the course page you can choose “Remove my data” to delete your email and progress for that course at any time; the course owner can also remove a learner. We retain learner enrollment data for up to 18 months after your last activity and then delete it automatically, and we hard-delete erased records on a daily schedule. To exercise any data right, you can also contact hello@hippokit.ai.

Content Moderation

To keep HippoKit safe and lawful, we automatically scan uploaded files and the text we extract from them to detect and block prohibited content (such as illegal material or content depicting child sexual abuse, terrorism, or other serious harm). Uploads that fail these checks are rejected and logged. See our Terms of Service for what is and is not allowed.

Data Retention

We retain your uploads and the content we generate from them for as long as needed to provide the service. You can delete a kit or your account at any time, and you may request deletion of your data by contacting us; we delete the associated content on your request.

Data Security

All data is encrypted in transit (TLS) and at rest. We use Google Cloud Platform infrastructure with enterprise-grade security controls. We never sell your data, and our AI sub-processors do not use your content to train their public or foundation models.
