A full Zoom meeting mock-up that runs in your browser. Launch a poll as the professor, then switch to the student view and answer it. No install and no sign-in.

What it does

A live classroom loop inside Zoom.

Four tools that all run on the live lecture transcript. Professors check understanding during class, and students follow along and fill the gaps after.

Professor's Pulse

Quick comprehension checks, mid-lecture.

One click drafts a poll from the last few minutes of lecture. The professor edits it, launches it, and watches the answers come in live.

Warm-Up Arena

A timed review game built from the lecture.

AI writes review questions from the lecture, students race a countdown, and faster correct answers score higher on a live leaderboard.

Live Anchor

A live topic timeline and glossary from the transcript.

Momentum listens to the live transcript, marks every topic change, and defines new terms the moment they're said, in any of six languages. Join late or lose your place, and you can still see the current topic and every term defined so far.

Recovery Agent

Capture confusion in class, fix it after.

Students bookmark hard moments privately during class. After class, every bookmark turns into a recovery pack with plain-language explanations, practice prompts, and notes to download.

What it looks like

The actual Momentum interface, docked in the side panel of a live Zoom meeting. Blue tags mark the professor's panel; green tags mark a student's.

The full Momentum demo: the professor's Live Anchor panel on the left, the Zoom meeting gallery in the middle, and a student's topic timeline on the right — In a real meeting the panel docks on the right for everyone — shown side by side here, the professor's panel on the left and a student's on the right, so you can see both at once.

Pulse tab with an AI-drafted poll — question and four editable options with a Launch Poll button — Pulse drafts a check-in poll from the lecture. Every field is editable before launch.

A live poll card on the student panel with four answer options and a Submit Answer button — The poll lands on every student's panel the moment it launches.

Poll results with percentage bars for each option and a nine-response count — Answers tallied the instant the poll closes — zero grading.

Arena review screen listing two AI-written quiz questions with highlighted correct answers and Edit buttons — Arena writes quiz questions from the lecture; review and edit before starting.

An Arena quiz question on the student panel with a 13-second countdown and four options — Students race the countdown — faster correct answers score more.

Live Anchor tab with an AI-built topic timeline — the current topic is highlighted with three key points — Live Anchor turns the transcript into a topic timeline as the professor speaks.

Live transcript tab with timestamps, a topic banner, and technical terms highlighted in blue — The raw feed: a live transcript with key terms highlighted.

Student timeline with the current topic marked NOW, key points, and Bookmark and Note buttons — Students follow the same timeline and bookmark any topic with one tap.

Glossary tab with five searchable terms defined from the lecture, each with an add-to-notes button — A glossary that writes itself — searchable, translatable into six languages.

Bookmarks tab listing two saved moments, one auto-captured from a spoken cue — Bookmarks — including moments auto-captured when the professor says "this will be on the exam."

My Notes panel with markdown notes assembled from topics and glossary terms, plus Copy and Download buttons — Smart notes: capture topics, terms, and bookmarks, then download as Markdown.

Fellowship project

Made through the Zoom Fellowship at ASU Next Lab.

About the program

The Zoom Fellowship pairs ASU students with the Zoom developer platform.

It's run by Next Lab, ASU's emerging-technology studio focused on the future of teaching and learning. The goal is working products that real classrooms can actually use. Momentum is one of three projects in the 2025 cohort.
