We build learning-first products that help people study more efficiently, explore big ideas faster, and build consistent habits—on the web today, and on mobile when available.
Make knowledge more accessible and more usable: less friction, clearer learning, and better outcomes for real people with real schedules.
We design products where learning feels simple and repeatable. That usually means:
AudiobookHub is an "audio hub" for discovering books quickly and learning efficiently, built around short, audio-friendly summaries and easy browsing across many categories.
It's designed for different kinds of listeners—busy readers, time-starved learners, and reluctant readers—so users can grasp core ideas fast, learn during commutes/chores, and build a lasting habit.
AudiobookHub includes discovery navigation (Home, My Shelf, Categories, New Releases, Blog) and a "My Shelf" concept for listening history and progress.
Prep4SSAT is an SSAT preparation platform focused on real practice and targeted improvement. It offers resources such as SSAT upper/middle level materials, full-length past tests, and focused practice modules (verbal, reading, quantitative, etc.).
Prep4SSAT supports multiple languages (English / 한국어 / 中文) and provides a contact channel for learners.
We aim to ship products that are:
We take privacy seriously and publish clear policies for our products. For example, Prep4SSAT's privacy policy explains what data is collected, how it is used, and includes specific disclosure about Google Sign-In; it also states it does not sell personal information.
AudiobookHub publicly provides About / Privacy Policy / Terms of Service / Contact pages from its website footer, and the About page includes company identity and contact details.
If you need help with any of our products, please contact us by email. We typically respond within 1–3 business days.
