You recognize every term in your notes. Then you close the page and try to explain one. An AI quiz generator from notes can turn that material into fresh questions, giving you a way to check what you can recall and use. Lensia's Chrome sidebar lets you supply your own study notes, request one practice question at a time, and discuss the reasoning after your attempt. Install Lensia free to try a short practice session on a topic you have already studied.
Give the assistant the material you want to learn
Start with a lecture outline or a section of your own notes. A short reading you are reviewing works too. Name the topic and your level of familiarity. A broad topic without source material can lead to questions about ideas you have not covered.
Try: "Create new practice questions based on these notes about supply and demand. Stay within the concepts provided. Ask one question at a time and wait for my answer before explaining it."
That instruction makes the exercise a conversation with pauses. You see the question, make an attempt, then ask for feedback. The questions are generated practice in chat. You can adjust them as you go.
If your notes need organizing first, use the study guide workflow. A guide can help define the material before you start testing your understanding of it.
Set up a small practice session
Click Lensia's Chrome toolbar icon to open sidebar chat, then sign in with Google. Paste your notes or attach a supported file using the attachment control. For PDFs, the combined limit per message is 2 MB on Free, 10 MB on Basic, or 20 MB on Pro, with up to five PDFs.
- Choose one section of notes you have already reviewed.
- Tell the assistant which concepts to include.
- Request five fresh questions, delivered one at a time.
- Ask it to withhold the answer and explanation until you respond.
- Attempt each question before returning to your notes.
- Discuss the reasoning, then record any concept to revisit.
Start with five questions. A small batch lets you assess whether the questions fit your material before generating more. If one uses an idea absent from your notes, say so and request a replacement.
Free includes sidebar chat within its usage allowance. You can compare plans when you need larger PDF attachments or more room for longer sessions. Our PDF guide covers document questions and file limits.
Choose question types that reveal understanding
Explain a concept in your own words
Ask for a short-answer question: "What is the difference between these two concepts? Give a new example of each." Your response shows whether you understand the distinction without depending on the wording in the notes.
If you get stuck, ask for a hint that names the relevant concept but leaves the answer open. You can then make another attempt before requesting the explanation.
Apply an idea to a new situation
Ask for an unfamiliar example using a familiar principle. In economics, that could be a change in a market condition. In biology, it might be a scenario that uses a process described in the lecture. Keep the question within your source material.
Prompt: "Write a new application question using this concept. Make the scenario different from the example in my notes. Do not introduce extra facts I would need to look up."
Use multiple choice carefully
Ask for plausible choices, then explain why you selected one. After your attempt, discuss why the other options fail. Reasoning behind the choice tells you more than the letter alone.
If two options seem defensible, point that out. The generated question may be ambiguous. Ask the assistant to revise it so the distinction depends on a clear feature from the notes, then try a new version.
Keep the answers out of sight until your attempt
Ask the assistant to wait after each question. A prompt can guide that behavior, but it is not a technical guarantee that no answer will appear early. If the reply includes the solution, ask for a new question and restate the instruction.
Avoid requesting a question and its answer in the same block if you want to recall the idea before seeing the explanation. Seeing the explanation first can make the question feel easier than it would have been on its own.
You can answer briefly and include your uncertainty: "I think the direction changes because of this condition, but I am unsure about the second step." That gives the assistant a specific piece of reasoning to discuss.
A partial attempt is useful. It shows where your understanding stops. Ask for one hint or a correction to that part instead of requesting another full explanation of the whole topic.
Review a mistake before moving on
When you miss a question, compare your reasoning with the relevant passage in your notes. Did you confuse two definitions, overlook a condition, or remember the rule but apply it in the wrong situation?
Ask: "Identify the first step in my reasoning that does not fit the notes. Explain that step, then give me a new question on the same idea."
The new question should change the example or numbers while keeping the concept. That gives you a chance to use the explanation rather than repeating the answer you just saw.
If the assistant's correction conflicts with your source, check the source directly. Generated answers can be wrong, including answers to questions the same assistant generated. For an unfamiliar term, ask it to point to the relevant passage and distinguish added background from the notes.
Our article reading guide can help you unpack the original explanation when the source is a long online reading.
Use your results to choose the next review
At the end of a batch, ask for a short recap based on the answers you actually gave: which concepts were clear, which needed hints, and which need another look. Keep that recap descriptive rather than treating a chat response as an official score.
Write the weak concepts in your own notes and revisit them in a later session. You can ask for another small batch covering the same ideas with fresh examples. Conversation history helps you return to the earlier discussion, but supply the relevant notes again if the thread has become long or changed topics.
For vocabulary, request a few question-and-answer pairs you can copy into your preferred flashcard tool. Lensia can draft the text; this workflow does not promise a built-in flashcard scheduler or direct export integration.
Finish with something you can explain
Choose one idea from the session and explain it without looking at the guide. Give an example, name the condition that matters, and describe a common confusion. If you still need the notes, that tells you where the next session should begin.
You can combine this practice routine with the study guide approach: organize a short section, explain the difficult part, then try fresh questions. Keep each step small enough to complete.
