ClassAI is a real-time polling and Q&A interaction platform for lectures, events, and training. Its core goal is to provide instructors with an efficient way to interact in real time with hundreds of audience members and to automatically collect, analyze, and report lecture data.
[Main Uses] Used for real-time interaction in lectures, corporate events, classroom teaching, public institution training, and similar settings. Participants do not need to install an app or register as members; they can enter via QR code or a 6-digit PIN and participate by simply entering their name.
[Main Capabilities] The platform provides 20 interaction modes, including: multiple choice, choose one of two, subjective questions, ranking, word cloud, opinion collection, buzzer quiz, betting quiz, real-time questions, scenario response training, random drawing, comprehensive assessment, photo message board, 1-on-1 showdown, stance selection, participant-generated questions, number guessing, AI vs. human preference prediction showdown, elimination tournament, and budget auction.
There are 9 AI automation functions: automatic scoring of subjective questions (0-100 points + feedback, about 30 seconds); scoring words or phrases according to criteria; evaluating questions without standard answers based on logic, specificity, and appropriateness; automatically selecting the TOP 3 excellent answers; generating an analysis report by synthesizing team or overall answers; after entering a topic, generating 5-10 questions plus correct answers and explanations in about 30 seconds; generating 3 sample answers from different perspectives; comprehensively assessing and automatically flagging perfunctory answers or cheating behavior; and generating a four-part PDF report in about 10 seconds after the lecture ends.
The report contains four parts: core outcomes (2-3 sentence summary), TOP 3 strengths, TOP 3 improvement points, and educational recommendations (2-3 sentences).
There are 6 auxiliary functions: instructor-participant chat (including anonymous mode and full-screen display), timer (countdown for breaks/discussions/presentations, displayed as an overlay on the projected large screen), attendance records and manual score adjustment, real-time leaderboard (one-click display of ranks 1-10 on the projector), large QR code pop-up (no registration or installation required), and automatic tutorial and help restart for first-time use.
[How to Use] You can start in three steps: 1. After registering, click “New Lecture” to create a room. After entering a topic, AI generates 5-10 questions, or you can write them yourself or import them from a question bank (about 5 minutes); 2. Display the QR code and 6-digit PIN on the projector. Participants scan it with their phone camera and enter their name to join (about 30 seconds); 3. The instructor opens questions one by one, answers accumulate in real time as charts, subjective questions are scored by AI, and clicking “End Lecture” generates a PDF report in about 10 seconds.
The instructor's laptop shows answers and control buttons, the projector shows questions and results, and participants' phones show answer buttons, with all three screens synchronized. It supports offline, online (Zoom/Teams), and hybrid modes.
[Applicable Scenarios] Corporate events: start with company trivia OX questions,team-versus-team survival quiz to liven up the atmosphere, then summarize the company with a word cloud, and after it ends use the PDF report directly as a training results report. Workshops and training: obtain authentic diagnostics through anonymous voting, have 100 subjective answers scored and given feedback by AI within 30 seconds, and display excellent answers to guide discussion. School education: review with betting quiz, have AI score questions without standard answers by logic in discussion mode, conduct online sessions through Zoom/Teams screen sharing, and use it free for up to 20 people.
[Limitations and Pricing] The free version supports up to 20 people, provides 4 basic modes (multiple choice, polling, Q&A, word cloud), includes a watermark, saves results for 30 days, and reserves the 11 gamification modes for Pro. The Pro version unlocks all 20 modes, supports up to 1000 people per room, offers a 7-day free trial, and after the trial is billed annually at about 2,600 KRW per day on average, with cancellation available at any time.
