A quiz generator that converts your textbook chapters or lecture notes into practice questions—all running on your phone, offline, without uploading anything to the cloud. This is how on-device AI transforms study materials into personalized quizzes in seconds.
The Student Problem: Endless Quizzing Cost
High-quality practice quizzes are essential for learning. When you're studying for an exam or mastering new material, simply re-reading notes isn't enough. You need to test yourself, identify weak spots, and reinforce concepts through retrieval practice.
But most quiz-building tools are expensive, cloud-dependent, or inflexible. Quizlet charges per feature. Learning platforms lock you into their ecosystem. ChatGPT charges per query, and every question you generate sends your study material to OpenAI's servers. None of these solutions are ideal for students who want privacy, affordability, and control.
What if you could generate unlimited practice quizzes from your own course materials, offline, for a one-time $2 cost? That's what a quiz generator in MyBenAI does.
How On-Device Quiz Generation Works
Quiz generation is built on two core pieces: your study material (in a notebook) and an on-device language model.
First, you add your source material. Scan textbook pages, upload lecture PDFs, paste lecture notes—anything you're studying. MyBenAI indexes this material using on-device RAG (Retrieval-Augmented Generation), breaking it into searchable chunks and embedding them in a local vector database. All of this stays on your phone.
Next, you ask the AI to generate quizzes. Instead of sending your material to the cloud, the model runs locally on your device. When you request "Create 15 multiple-choice questions about Chapter 3," the app retrieves relevant chunks from your notebook, passes them to the local language model, and the model generates custom questions tailored to that specific material. No network call, no data upload, no transcript stored on a remote server.
The result: practice questions that directly target your actual study materials, not generic questions about the topic.
The Typical Workflow
Here's how a student would use this in practice:
- Create a notebook. In MyBenAI, create a new notebook. Give it a name like "Biology 201: Cell Biology."
- Add source materials. Add your course materials—textbook photos (via phone camera or OCR), lecture notes, PDFs, images. The app automatically scans and indexes everything. Progress is incremental; adding more materials as the semester progresses works seamlessly.
- Generate quizzes. Chat with the notebook. Ask: "Give me 20 multiple-choice questions testing Chapter 5." Or: "Create a practice quiz on DNA replication with a mix of recall and application questions." Or: "Quiz me on the Krebs cycle and osmosis."
- Study and repeat. Answer the quiz, check answers, then generate a new set of questions from the same material. Each quiz is fresh because the model regenerates it.
- No storage needed. Everything lives in the app. No login, no cloud storage, no data leaks. Uninstall the app, and everything is gone.
Question Quality Depends on Source Material
A critical trade-off: the model can only ask questions about material you provide. If your textbook emphasizes cell division but glosses over mitochondrial dysfunction, the generated quizzes will reflect that imbalance. The model works with what you feed it.
Also, local models (especially smaller ones like Qwen3 1.7B or Llama 3.2 1B) sometimes generate redundant or slightly awkward questions. They're not as sophisticated as Claude or GPT-4. But they're fast, local, and good enough for most study scenarios. If you need absolute perfection, you'd use a cloud AI. If you want fast, cheap, offline quizzes tailored to your exact materials, on-device generation wins.
Customizing Quiz Type and Format
You're not limited to one format. You can request:
- Multiple choice: "5 multiple-choice questions with 4 options each on Chapter 2."
- Short answer: "10 short-answer questions about the Electoral College."
- True/false: "Give me 20 true/false questions on the Periodic Table."
- Essay prompts: "Create 3 essay-style questions comparing photosynthesis and respiration."
- Fill-in-the-blank: "Generate 15 blanks testing vocabulary from my Spanish notes."
- Mixed format: "Quiz me with 5 MC, 5 short answer, and 5 true/false on World War II."
You can also control difficulty: "Easy questions for review" vs. "Hard questions pushing deep understanding." The model adjusts based on your notebook's material and your request.
Offline Means Always Available
Because the model runs on your phone, you can generate quizzes anywhere: on a subway commute, in a library with spotty WiFi, or during a flight. No internet required. No rate limits. Generate 50 quizzes in a row if you want—no cost, no API throttling, no waiting for cloud servers.
This is especially valuable for students who study during dead time or who live in areas with unreliable connectivity.
Compare to NotebookLM and Other Tools
Google's NotebookLM generates study guides and answers questions about notebooks, but it uploads your materials to Google's servers. If you're concerned about privacy (or school policies around cloud uploads), that's a dealbreaker. MyBenAI keeps everything local.
Quizlet offers quiz generation but charges for it and requires cloud storage. For a student using quizzes daily, the cost adds up.
With MyBenAI, you pay $2 once. Then unlimited quiz generation, forever, on your device, with your data.
Homework and Test Prep Scenarios
Weekly homework: After each class, generate a practice quiz from your notes. Answer it, identify weak spots, revisit those topics, regenerate, and repeat. This retrieval practice is one of the most effective study techniques.
Exam cramming: Three days before an exam, generate 50 quizzes from all your course notes. Take them rapid-fire, see which topics stump you, request more quizzes on those specific topics, and drill deeper.
Subject mastery: Not just exam prep. If you're learning a language, math, coding, or any skill, quizzes reinforce learning. Generate quizzes from your learning materials constantly; the local model never tires and never charges per quiz.
Integration With Citations and Source Tracking
Because MyBenAI notebooks use on-device RAG with automatic citations, when you generate a quiz, the model can optionally note which notebook section each question targets. You can ask: "Show me which chapter each question comes from." This is useful for reviewing: if you miss a question, you know exactly which section to reread.
Getting Started
Open MyBenAI, create a notebook, add your study materials, and start chatting. Request a quiz. Within seconds, you'll have fresh practice questions tailored to your exact curriculum. No setup, no subscriptions, no cloud account.
If you're a student drowning in paid quiz platforms and cloud-dependent study tools, this is a cleaner, cheaper alternative. If you're a teacher looking for a tool to suggest to students, MyBenAI is $2 one-time, no ads, and your message content never leaves the device.
