Your lecture notes contain the right terms, but reading them back does not explain how they fit together. An AI study guide generator can help organize those notes and turn the confusing parts into questions you can work through. In Lensia's Chrome sidebar, you can paste your own notes or attach a PDF, ask for a clear outline, and follow up on the concepts that need more attention. Install Lensia free and start with one lecture rather than a whole semester of material.
Use your own notes to set the scope
A broad request such as "teach me biology" gives the assistant little guidance about what you have covered. Your notes provide the vocabulary, examples, and level of detail relevant to the topic you are learning.
Choose a short section you want to understand better. Include the title and any learning goals supplied with the material. Tell Lensia what is difficult: perhaps the definitions seem similar, a diagram has unfamiliar labels, or the steps of a process do not make sense yet.
Try: "Organize these lecture notes into a study guide. Use the ideas in the notes, preserve the key terms, and mark any unclear or missing explanation. I am especially confused by the difference between diffusion and osmosis."
Keep gaps visible. If your notes say "important example here" but never record the example, an invented one should not be presented as something from the lecture. Ask the assistant to distinguish its own illustrative example from the material you supplied.
Put the material beside a conversation
Open Lensia from its Chrome toolbar icon and sign in with Google. Paste typed notes into sidebar chat, or use the attachment control for a supported file. PDF attachments are available on every tier within the plan's size limits.
- Pick one lecture or chapter section.
- Supply your notes and name the topic.
- Ask for an outline with key terms and relationships.
- Read the outline beside your original notes.
- Choose one confusing concept and ask a follow-up.
- Add the explanation you checked to your own study document.
You can attach up to five PDFs per message, with a combined limit of 2 MB on Free, 10 MB on Basic, or 20 MB on Pro. Start with the relevant file or passage. More material is not always more useful if you only need to understand one concept.
Our PDF reading guide explains how to ask document questions and check section references. You can compare plans if file size or usage becomes a regular constraint.
Ask for a guide that shows relationships
An outline can list the topics without explaining why one idea depends on another. Ask Lensia to explain the relationships between the concepts in your notes.
Prompt: "Group these notes by concept. For each group, give a short explanation, the terms I need to know, and the connection to the previous group. Do not add topics that are absent from the notes."
For a history lecture, that might mean distinguishing the sequence of events from the reasons people give for them. In chemistry, it could mean showing how a definition connects to a particular type of calculation. For language learning, it might mean grouping expressions by the situations in which you use them.
Ask for one concrete example when a definition remains abstract. Then ask which features make the example fit the definition. If you can explain that connection in your own words, the guide has become more useful than a list to reread.
Use follow-ups to unpack the difficult part
When two concepts sound the same
Ask for a comparison using the exact terms in your notes: "Explain the difference between these two terms, then give one example of each. Tell me which detail determines the category."
Check the explanation against your course material. Sometimes a field uses a term more narrowly than an everyday explanation does. Retain your lecturer's wording when that distinction matters.
When a process has too many steps
Ask why the transition between two steps happens. "What has changed after step two, and why does that allow step three?" is a more useful question than requesting the entire process again.
Try describing the process back to the assistant without looking at the guide. Ask it to identify the first point where your explanation stops matching the notes. Your own explanation gives you something specific to improve.
When the notes are too compressed
Paste the short passage and ask which assumptions it leaves unstated. Tell the assistant to label any background information it adds. That lets you distinguish the lecture's content from the extra context you may need to understand it.
For an online reading alongside your notes, use the article summary guide to identify its claim and supporting examples.
Make the guide manageable for one session
Ask for a review plan based on the time you actually have. If you have twenty minutes, request a small set of concepts and one check for each. You can always return to the rest later.
For example: "Based on these notes, suggest a twenty-minute review session. Start with the two concepts I marked as confusing. Include a chance for me to explain each concept from memory."
The schedule is a suggestion, not a prediction about how quickly you should learn. Spend more time where your explanation is incomplete. Skip a definition you can already use correctly in a new example, and come back if later questions show a gap.
Small review targets are easier to finish. "Explain why this happens" is concrete. "Understand the whole chapter" makes it hard to decide whether the session worked.
Turn the guide into fresh practice
After reviewing a section, ask for a few new questions based on its concepts. Request one question at a time so you can answer before seeing an explanation.
- Ask for a definition in your own words.
- Explain why a new example belongs to a category.
- Compare two related concepts.
- Describe what would change if one condition changed.
These prompts help you use the material in different ways. They also reveal when you can repeat a sentence but cannot yet explain it. Our practice question guide shows how to keep the answers separate and review mistakes.
Check any unfamiliar statement against your notes or textbook. If the assistant introduces a fact you cannot verify, leave it out of your saved guide until you can. A fluent explanation can still be wrong.
Keep a record of what became clearer
At the end of the session, write a few lines in your own words: what you understood, what is still confusing, and which passage you will revisit. Bookmarks can save a useful sidebar response; conversation history lets you return to the discussion.
Keep the guide with its source notes so you know where the content came from. Do not include private information about classmates in attachments. If you want outside background, Basic and above offer web search, and our research workflow explains how to check those sources.
Open your next study session in Lensia with one lecture's notes and a concept you want to explain yourself.
