What It Is

Hi-Boo（하이-부!）is a Chrome extension built for the Hi-Learning platform of the Gyeonggi Provincial Office of Education in South Korea, positioned as a “Hi-Learning assistant” for teachers. Through the browser sidebar, it brings together teaching materials, timetable/class management, assignment downloads, AI evaluation feedback, and Classboard activity result management. Its activation requirements are clearly defined: teachers must log in with a Hi-Learning teacher account at hi.goe.go.kr, and the extension’s features are enabled only after the account is detected.

Core Capabilities and AI Aspects

The product’s main strength is teaching workflow automation rather than general-purpose AI content creation. AI-related information is mainly focused on “written/essay-style evaluation”: teachers can check each student’s AI feedback status by assignment and download an overall feedback report as an Excel file, making it easier to distribute results and track students who have not yet received feedback. However, the website does not disclose the underlying model, grading criteria, feedback generation mechanism, or human review process, so it is difficult to assess the quality and explainability of its AI evaluation.

Features, Integrations, and Privacy

Beyond AI feedback, Hi-Boo supports bulk downloading of course materials and student-submitted assignments, automatically organizing files by “하이부 / category / name / year-month.” It can monitor in real time how many students are online, studying, or waiting in the unified learning window, and it can also distribute or reclaim student praise points in bulk. In Classboard scenarios, it supports exporting group results as PDFs by group and tracking student contribution levels in real time. On privacy, the FAQ states that it does not operate independent servers or transmit user data externally; processing is completed entirely inside the browser, and data is deleted from memory after the session ends. This is a plus for educational use cases.

Pricing and Ease of Use

The webpage does not provide information on pricing, subscriptions, free quotas, or payment methods. What can be confirmed is that it can be installed from the Chrome Web Store and supports Chromium-based browsers such as Chrome, Edge, and Whale, while Safari and Firefox are not supported. The installation process is fairly simple: add the extension, log in to Hi-Learning, and open the sidebar to start using it, with no additional setup required.

Pros, Cons, and Who It’s For

Its strengths lie in how closely it matches the real workflows of teachers in Gyeonggi-do, especially those who frequently need to download assignments, organize evaluation feedback, and manage group activities. Its drawbacks are its extremely narrow scope—it is limited to Hi-Learning teacher accounts—and the lack of information on Chinese-language support, pricing, and AI model details. For users in China, access status is unknown, and because the product depends on a Korean regional education platform account, its practical usability is very low. If you need a more general-purpose classroom management tool, alternatives such as Google Classroom, Microsoft Teams for Education, Canvas, or Moodle may be more suitable.
