AI Summary

Ziyang Vocab Master is a free, browser-based tool that helps students turn any PDF (like a GRE textbook or class handout) into a personalized vocabulary study system. It works in three steps: extract words from a PDF, enrich them with AI-generated definitions and images, and study them using interactive flashcards with spaced repetition. Everything runs locally in your browser, so your data stays private. The project is open-source and created by a high school student as a public welfare project.

How It Works

📚 Discover the vocab problem

A student struggling with GRE vocabulary discovers there's a free tool that turns any PDF into a personalized word list.

2
📄 Drop in your PDF

3
🤖 Let AI enrich your words

You connect your AI account and watch as the tool automatically adds definitions, example sentences, pronunciation guides, and pictures to each word.

4
🧠 Study with flashcards

AI-Generated Review

What is Ziyang-Vocab-Master?

Ziyang-Vocab-Master is a single-file HTML web application that transforms PDF textbooks into personalized vocabulary study tools. Built entirely in HTML with JavaScript, it runs locally in your browser with no server required. The app extracts words from any PDF, enriches them using Gemini AI (adding definitions, phonetics, example sentences, and images), then lets you study through flashcard-based spaced repetition with pronunciation testing via microphone.

Why is it gaining traction?

This fills a gap that mainstream vocabulary apps ignore: studying words from YOUR materials, not their pre-made lists. Students stuck with GRE prep books or classroom handouts finally have a free way to build custom word lists without paywalls. The privacy angle matters too—everything stays on your machine, no accounts, no data collection. For developers, the open-source nature means you can fork it and adapt it for any language or curriculum.

Who should use this?

High school and college students preparing for standardized tests with specific prep materials will get the most value. Language learners working from textbooks or academic papers can skip generic word lists entirely. Teachers wanting to create custom vocabulary sets for their classes have a free, self-hosted option. Developers interested in building similar educational tools have a readable reference implementation.

Verdict

At 19 stars with a 1.0% credibility score, this is a passion project from a high schooler—not production-grade software. The feature set is genuinely useful, but test coverage, documentation, and long-term maintenance are unknowns. Worth trying if your use case matches, but treat it as a starting point rather than a finished product.
