StudyHub

English · 简体中文

Turn your lecture slides into questions that each link back to their page; finish a round and see yourself getting it.

Free and open source, your materials stay on your computer; pick your own model and pay for what you use.

StudyHub is a plugin for DeepSeek Harness (DSH), an AI agent app. DSH runs as a desktop app or as a web page served from your own computer, and StudyHub opens inside it.
