ArkJunior

EXPERT-CURATED. AI-NARRATED.PAUSE, ASK, WONDER.

Give it your slides and supporting materials, and it creates a narrated presentation in a voice of your choosing, with a script you can review and edit. Whether you’re teaching a class, sharing research or briefing a team, your audience can pause anytime to ask questions and explore what interests them. Their questions and feedback help you see what resonates, where confusion lies and what to explain or discuss next. Now integrated with HKU LMS.

Who it’s for

Purpose

A student raises her hand with a question during a lecture

Teaching and learning

Turn course materials into interactive lectures. Students ask when they are curious or stuck; their questions inform your next teaching move.

Research sharing and feedback

Share a presentation with the paper as supporting material. Colleagues can explore the work, ask questions and offer feedback; researchers can review those exchanges.

ExampleMessy Jobs · Prof Jin Li (opens in a new tab)

Team communication

Make a town hall, project briefing or onboarding presentation available afterwards. Colleagues—including those who missed the meeting—can listen, ask questions and clarify what matters to them.

What colleagues say

In their words

That is the best thing in education technology I’ve seen in a long time.
Professor Jason WoodardSchool of Innovation (I-School)

I am most impressed with the teaching text ArkJunior generates from slides—and its potential to help colleagues develop more flipped-classroom, student-centered teaching!
Professor Pauline ChiuDepartment of Chemistry, Faculty of Science

A question a student never asks is a teaching opportunity instructors never see. ArkJunior gives students a safe space to ask. At last, we can see.
