A Practical System for Your Online Course Notes

#Why You Don't Remember What You Watch

The global e-learning market is on track to hit $1 trillion by 2028. More of us are learning from videos, but we're all hitting the same wall: video learning has a retention problem. We watch, but we don't remember.

The old method is a mess. Constantly pausing a video to write in a notebook breaks your focus. Taking screenshots creates a folder of scattered images with no context. You end up with disconnected thoughts that are almost impossible to make sense of later.

This guide isn’t about "taking better notes." It’s about building a reliable workflow—a system to create a searchable, permanent knowledge base that helps you actually remember and apply what you’ve learned.

#Why a System Beats Random Notes

Jotting down points here and there feels productive, but it fails in the long run. A structured system provides a framework for capturing, organizing, and—most importantly—reviewing.

Here’s how an ad-hoc approach compares to a systematic one for online course notes.

A systematic approach turns your notes from a temporary crutch into a long-term asset. The goal is to beat the Forgetting Curve, the natural process of how our memory decays. A good note-taking system is your primary defense against it.

This means building a process that's efficient while learning and effective for long-term recall. The rest of this guide walks you through setting up this exact system. For more on the science, see our article on how to boost retention with video learning.

#Step 1: Set Up Your Digital Learning Hub

Before you press play, create a dedicated home for your knowledge. For anyone serious about learning and data ownership, local-first tools like Obsidian are the best choice.

Your knowledge should belong to you, not be locked on a company's server. By building your system around plain Markdown (.md) files, you guarantee your online course notes are future-proof. You own the files. Move them, back them up, grep them—they're just text.

#Choose Your Core Tools

The right tools get out of your way. For this workflow, you need two things: a place to store knowledge and a way to capture it.

• Your Knowledge Base (The "Vault"): We recommend Obsidian. It’s a free app that turns a folder of Markdown files into a powerful, interconnected knowledge base.
• Your Capture Tool: Manually pausing, typing, and taking screenshots is tedious. A dedicated capture tool is necessary. HoverNotes is a Chrome extension that watches videos with you, generates AI notes, and saves them as Markdown directly to your file system.

This combination creates a direct pipeline from a video lecture into your permanent, searchable library.

Here’s what a clean Obsidian setup can look like. The notes are neatly structured for easy access.

The layout is minimal, helping you focus on your notes while navigating your knowledge base.

#Create a Simple and Effective Folder Structure

Consistency is key. A simple folder structure is the difference between a library and a junk drawer. Inside your Obsidian vault, create a main folder called 01_Courses.

Inside, make a new subfolder for every course. A clear naming convention saves headaches. For example:

• Udemy - AWS Certified Solutions Architect
• Coursera - Machine Learning Specialization
• YouTube - Python for Everybody

This simple hierarchy keeps everything tidy. A few minutes of setup saves hours of cleanup later. For a deeper dive, check out our guide on how to create a knowledge base.

With your vault and folder structure ready, the next step is to master the capture process.

#Step 2: Turn Video Lectures into Actionable Knowledge

With your digital hub ready, it's time to capture high-quality online course notes. The goal is to make note-taking so seamless that you can focus on understanding the material, not the clumsy dance of pausing and typing.

A good capture workflow minimizes friction. If you’re using a tool like HoverNotes, you can enable a distraction-free mode that places the video on one side of your screen and a notes editor on the other. This blocks site ads and "up next" recommendations, keeping you focused.

The process is a simple but effective workflow: pick your tool, set up your vault, and start capturing.

A solid foundation—the right tool and an organized vault—makes the note-taking process work.

#Shift from Transcriber to Active Learner

When AI handles the transcription, your role changes. You're no longer scrambling to type every word. Instead, you can watch, listen, and think critically. The AI produces the first draft, leaving you to be the editor.

Your job becomes more valuable. You can:

• Add your own insights: While the AI generates notes, type your thoughts and questions directly into the editor.
• Correct or clarify points: AI isn't perfect. Quickly edit the generated text to reflect the instructor's meaning or your understanding.
• Highlight key concepts: Use bolding or headings to make important takeaways stand out.

This workflow turns passive viewing into an active learning session.

#Capture What Transcripts Always Miss

The biggest failure of transcript-only tools is their blindness to visual context. Much of the information in technical courses—from coding tutorials to engineering lectures—is shown, not said.

A transcript might say, "as you can see in this diagram," which is useless when reviewing notes a week later.

This is where visual capture is essential. Instead of writing "see diagram," a tool that watches the video can grab the actual visual. Unlike tools that only parse transcripts, HoverNotes watches the video to capture what's actually on screen. You can use its "snip" feature to select just the relevant part—a code snippet, a formula, or a diagram—and embed it directly into your notes.

Every screenshot includes a clickable timestamp—one click returns you to that exact moment. This feature alone eliminates hours of scrubbing through videos to find a specific point. This workflow is invaluable whether you're learning on Coursera, Udemy, a private university portal, or from local video files. For a detailed walkthrough, check our guide on how to take notes on videos.

#Step 3: From Raw Text to Structured Knowledge

You've captured the raw content. Good start, but that's just the raw material. The real learning happens when you shape that text into something that makes sense to you. This turns a jumble of words into a permanent piece of your knowledge library.

This isn't just a student problem. Corporate e-learning is exploding, with companies seeing higher revenue per employee with solid training programs. Professionals need reliable systems to manage what they learn. More on the insane growth of corporate online learning shows why this skill is critical.

#Apply Structure with Markdown

Your first pass after capturing should be about creating visual structure. A wall of text is a nightmare to review. Simple Markdown formatting makes notes instantly more useful.

Break up long paragraphs and use formatting to signal importance:

• Headings (##, ###): Outline the main topics and sub-topics. This creates a scannable table of contents for the lecture.
• Bold Text (**text**): Make key terms, definitions, or critical takeaways pop.
• Bullet Points (*): Turn lists into bullet points. They are much easier to read than a comma-separated sentence.
• Blockquotes (>): Pull out powerful quotes from the instructor or any "aha!" moments.

This isn't just about aesthetics. It's a mental exercise that forces you to identify the core structure of the information, which is a huge step toward understanding it.

#Weave a Web of Connected Ideas

Isolated notes are a dead end. The real power of a tool like Obsidian comes from connecting ideas. This transforms a collection of documents into a web of knowledge, much like your brain works.

After structuring a new note, ask yourself: "What does this remind me of?" Then, start linking.

The goal is to never have an 'orphan' note—one that doesn't link to or from anything else. Every new piece of knowledge should connect to something you already know.

For instance, if your notes are on Python list comprehensions, you could link that concept back to a broader note on [[Python Fundamentals]] or even [[Functional Programming Concepts]]. This simple act builds mental pathways that make recall easier. This is a core idea in our guide on how to build a second brain.

#A Practical Tagging Strategy for Discovery

Links connect specific ideas; tags categorize them. A consistent tagging strategy makes finding what you need effortless.

Here’s a practical system:

• #status/review: Apply to any note you need to look over again.
• #type/concept: Use for notes that break down a specific idea (e.g., #type/concept/recursion).
• #course/aws-architect: Groups all notes related to a single course.
• #person/andrew-ng: Tags insights from a particular instructor.

This ensures that no matter how you try to find a note in the future—by topic, source, or status—you can pull it up in seconds.

#Step 4: Build a Review System That Sticks

Notes you never look at again are just well-formatted clutter. The final piece of the system is a practical review process that cements learning for the long term. This is how the time spent creating online course notes pays off.

The goal is to move past passive re-reading. We're going to use active recall, a method that forces your brain to retrieve information without peeking. This builds strong neural pathways.

#Active Recall in Practice

Your structured notes are the perfect raw material. Turn them into a self-quiz instead of just reading them over.

• Turn Headings into Questions: Treat each heading like a question. Before reading the content below it, try to explain the concept out loud or write it down.
• Explain the Screenshots: Look at a screenshot of a diagram or code. Before reading your notes or clicking back to the video, explain what it means and why it was important.
• Follow the Links: When you see a link to another concept, pause. Try to define the linked concept before you click on it.

This process feels harder than reading. That’s the point. The productive struggle makes the knowledge stick.

#Schedule Your Review Sessions

Consistency is everything. A simple, repeatable schedule makes all the difference. Block out 30 minutes every Sunday to go over the notes you took that week.

The Massive Open Online Course (MOOC) market is exploding, expected to hit $165.87 billion by 2030. Platforms like Coursera serve over 148 million users. With that much learning, an effective review system is essential. You can read more about the growth of the MOOC market to see how big this trend is.

#Effortless Retrieval for the Long Haul

A digital system like Obsidian or Logseq shows its power here. Six months from now, you won't remember every detail of a course. But when you need to recall a specific statistical method, a quick search for "logistic regression" in your vault will instantly pull up your note.

There it will be—your refined summary, key concepts, and the timestamped screenshot showing the formula. This closes the loop on the system, turning fleeting information into permanent, searchable knowledge. For more ideas, check our guide on how to make a study guide.

#Common Questions About This Note-Taking System

As you build this system, a few common questions come up.

#Is an AI note-taker essential for this?

No, but it's a massive shortcut. The core of this system is structure and review. An AI tool handles the transcription so you can spend your energy thinking about the material. You can follow this process by typing manually. Even without AI, the distraction-free mode and screenshots are worth it. You can use a tool like HoverNotes to get those features for free.

#How do I handle a huge course with 100+ videos?

This is where a system shines. For a large course, create a central index note, or a Map of Content (MOC).

Create a main note like MOC - AWS Certified Solutions Architect. Each video lecture gets its own note with a consistent name, like 01.1 - Intro to IAM. In your MOC, link to each lecture note. You end up with a clean, clickable table of contents inside your knowledge base.

#Can I use Notion or Google Docs instead of Obsidian?

Yes. While this guide focuses on local-first tools like Obsidian and Logseq because they give you ownership of your data, the principles are universal. Capture, structure, and review work on any platform. The most important thing is having one central, organized, searchable place for your notes. Notes from HoverNotes copy cleanly into Notion or Google Docs with formatting intact, so you can use whatever tool you prefer.

The timestamped screenshot feature alone saves hours of rewatching. You can try it out for free—you get 20 minutes of AI credits, no credit card required.
