PACE case study

Every second tells a story.

PACE turns AI quizzes, access codes, live activity, and teacher analytics into one classroom workflow.

A score tells the result. PACE shows the process.

Most quiz platforms only record whether a student was right or wrong. Teachers often need the story behind the answer: hesitation, answer changes, focus shifts, and questions that created confusion.

PACE connects AI-generated questions, secure access codes, fullscreen quiz sessions, real-time activity signals, and post-quiz analytics into one classroom workflow.

More than an AI quiz generator.

PACE combines quiz creation, live proctoring signals, and teacher analytics so educators can understand both performance and behavior.

AI Quiz Generation

Teachers can create MCQ and True/False quizzes from PDFs or custom prompts, with control over difficulty, number of questions, and time limit.

Real-time Student Monitoring

During the quiz, PACE records fullscreen exits, tab switches, window blur events, copy and paste attempts, and answer changes.

Teacher Analytics Dashboard

Teachers can view submissions, average scores, question timing, live heatmaps, AI-generated reports, and exportable CSV data.

A live dashboard for the teaching moment.

PACE gives teachers real-time visibility into how students are taking the quiz, not just how they scored after submission.

What we had to balance.

PACE needed to protect classroom integrity while staying practical, respectful, and focused enough for an MVP.

Monitoring without overreach

PACE records quiz-related behavior signals without reading clipboard content or tracking external websites.

Security vs convenience

Gmail verification, 30-day sessions, and access keys keep the classroom flow secure without making it slow.

Turning PDFs into quiz-ready content

AI must convert unstructured lecture material into clear MCQ and True/False questions.

Keeping the MVP focused

The product focuses on AI quiz creation, live monitoring, teacher analytics, CSV export, and student quiz history.

Focused on signals, not surveillance.

PACE is designed to help teachers maintain assessment integrity without becoming invasive. It records events that happen inside the quiz session, such as leaving fullscreen, switching tabs, copy/paste attempts, answer changes, and timing patterns. It does not read clipboard contents or identify which external websites students visit.

About us

PACE was built as a focused classroom product case study, shaped around teacher workflow, secure access, real-time signals, and responsible analytics.
