Working through a Udemy course? HoverNotes watches each lecture with you and writes clean, structured notes — capturing the on-screen code, slides, and diagrams a transcript misses, with timestamps you can jump back to. Everything saves straight to your Obsidian vault.
Join thousands of students, professionals, and lifelong learners who use HoverNotes to enhance their video learning experience.
What it is
HoverNotes is a browser extension that takes notes on Udemy course videos as you watch. Open any lecture and it turns it into organized, timestamped notes — written automatically by AI or typed by hand. Because the AI reads what is actually on screen, it captures the code, slides, and diagrams instructors demo, not just the spoken captions — and it grabs clean frames even on the protected players where a normal screenshot comes back black. Notes save as plain Markdown to your own Obsidian vault — local-first and private.
Udemy courses are full of code walk-throughs and slides you want to keep — but protected players often turn a normal screenshot into a black rectangle, and the transcript leaves the code out entirely. HoverNotes captures clean, timestamped frames of what is actually on screen and writes the notes for you, so nothing from the course is lost.
Why it's different
Udemy's player often returns a black frame to a normal screenshot. HoverNotes captures clean, timestamped frames of the code and slides as they actually appear — so you keep what matters.
The visual AI sees what is on screen — code walk-throughs, slides, and diagrams — and captures them exactly as the instructor demos them, even when the captions skip right over them.
Your notes save as Markdown directly to your own Obsidian vault on your machine. Nothing about your Udemy coursework is uploaded or stored in the cloud.

"For Obsidian users, this is an absolute must. This app is simple, but so incredibly useful, especially if you're doing any kind of YouTube tutorials that require anything visual: math, UI, any design things. It's really incredible. You can screenshot along the way and be able to catalog someone's entire design process. I love how I'm immediately able to open the files within Obsidian. Great job!"

"HoverNotes has genuinely changed the way I learn from coding tutorials. I spend a lot of time watching videos on YouTube and Udemy, and this tool makes everything so much easier. Instead of constantly pausing or rewinding to jot things down, HoverNotes automatically generates clean, well-organized notes in real time—complete with syntax-highlighted code snippets and helpful screenshots. It feels like having a smart study partner sitting next to me. The split-view mode is one of my favorite features. Being able to watch the video and see my notes side by side keeps me focused and saves a ton of time. It's especially great for technical content where switching between windows can be a pain. The interface is clean, intuitive, and clearly built with developers and learners in mind. What really sets HoverNotes apart is how intelligently it captures context. It doesn't just rely on transcripts—it actually 'watches' the video with you and picks up on diagrams, code examples, and even handwritten notes on screen. The AI-generated notes are impressively accurate and easy to review later, especially when you add a few screenshots to give it more context. I also really appreciate the flexibility of how it stores notes. You can access everything in the cloud, or connect it with Obsidian if you prefer to keep things local and private. Whether you're a student, a developer, or just someone who learns best from video content, I can't recommend HoverNotes enough. I've tried a bunch of note-taking tools, but this one is on another level."

"Forget other note-taking apps, HoverNotes is in a league of its own. As someone who's lazy when it comes to taking notes, I had tried a bunch of paid and free extensions, but nothing compares to HoverNotes. The AI-Notes feature is my favorite, letting me focus on what truly matters: learning. For developers, it's even better. What stands out is that it doesn't just use transcripts; it actually watches the video with you. This makes it powerful for understanding code, diagrams, sketches, and anything referenced in the video. The notes are well-formatted, with all code, commands, and key details neatly organized. Just take a few screenshots if needed, and you'll get detailed notes for review. It works on almost all websites, offers cloud storage, and you can always access your notes online. But the integration with Obsidian is perfect for those who prefer a private and local note-keeping option. Highly recommended for developers and students alike!"

"HoverNotes is an absolute game-changer for developers and learners! As someone who frequently watches coding tutorials on platforms like YouTube and Udemy, I found this tool to be incredibly efficient and intuitive. The real-time AI-powered notes, complete with syntax-highlighted code snippets and screenshots, have saved me so much time—no more rewinding videos to catch details! The split-view mode is a brilliant addition, allowing me to watch and take notes simultaneously. It's made my learning process smoother and more productive. Highly recommend HoverNotes to anyone looking to streamline their learning experience—it's truly exceptional!"
Abdallah Mtavya

"This is a must-have for anyone who watches video tutorials and needs efficient note-taking without constantly rewinding to see what they missed. It automatically generates structured summaries, capturing key points without requiring you to pause and write things down manually. Obviously nothing will ever take away the joy of manual note-taking but this complements it and makes it more efficient and time saving. The integration with YouTube and other video platforms is seamless, and the ability to export notes makes it even more convenient. This tool is a game-changer for students and professionals looking to save time and stay organized. I was really impressed on the first try and since then I've looked nowhere else. Looking forward to more diverse applications beyond coding tutorials."

"This is an incredibly useful application for anyone following video courses. It effectively breaks down language barriers, providing access to countless contents and dramatically speeding up the learning process. The application delivers on its promise of eliminating the need to rewatch videos just to take notes on relevant information. The notes are always accurate and surprisingly comprehensive, capturing even visual elements shown on screen that aren't covered in the audio. In some cases, the notes have proven to be clearer than the original presentations. Occasionally, I've encountered some duplicated sections, likely a consequence of how videos are segmented for AI analysis, but this is certainly preferable to the alternative of risking missing parts of the content. The ability to enhance notes with full-screen screenshots or specific area captures is excellent, as is the option to save notes locally in Obsidian. I've been using the application for over a month and have observed that it's constantly being improved and updated with new features, such as the ability to increase or decrease video playback speed. Perhaps the user interaction could still be refined - for example, the need to select the save vault each time - but if I had to keep only one Chrome extension, I would definitely choose this one. I've also experienced that the customer support is very responsive and helpful."

"What an amazing app! I use the for all my online studies to help me take notes while I watch. It doesn't just transcribe, it summarises perfectly. Hovernotes isn't too basic in summary, and isn't just transcribing word-for-word but retains the notable points of the video. Not just that, but when something is clearly referenced Hovernotes will often take a 'word-for-word' note of those parts making it truely unique. It ensures that it is accurate in what needs to be referenced for later, and summarises in anecdotal stories or side tangents. Exactly what I needed. Thanks for such a useful study companion!"

"I was really impressed by the ai taking notes on the video, although I find it a little annoying to have to specify every time the folder path to my vault. Another thing is that, there is no marks on the video afterwards that I already have a note about it, which could confuse me later on. I think that adding a marking of a note taken would really be cool. Beside that, it is one of the best add-ons for obsidian I could find here"

"awesome extention for not making but AI features are stricted for some minutes, if it's became free this will be a path braking extension a learner can use. Please try to collaberate pitch in with some higher company with this idea so that we can get the AI feature for free, All the best"

"Thank you for taking the time to create this wonderful Chrome plugin. However, I believe there are some areas where it can be improved. Firstly, after capturing a screenshot, the next entry point for adding a note is not centered, which requires me to take my hand off the keyboard to scroll to the next note. Secondly, when I enter 'Video Mode,' I receive an error message stating, 'This video is unavailable. Error code: 4.' If you could address these issues, the plugin would be almost perfect."

Questions
Yes. Install the HoverNotes browser extension, then open any lecture on udemy.com and turn on notes. HoverNotes watches the video and writes clean, timestamped notes, capturing the on-screen code, slides, and diagrams a transcript misses — or you can type your own notes by hand.
Yes. Udemy's protected player often turns a normal screenshot into a black frame — HoverNotes captures clean, timestamped frames of what is actually on screen, so you keep the code and slides instead of a black rectangle.
Real notes. A transcript is a raw wall of text; HoverNotes gives you organized notes with headings, syntax-highlighted code blocks, and timestamped screenshots of what is on screen — the kind of notes you actually study from.
No. HoverNotes is a note-taker, not a downloader. It never saves or re-hosts the course video — it only captures your notes and timestamped screenshots of what is on screen, saved privately to your own Obsidian vault.
Yes — that is the core difference. Because the AI watches the actual video frames, it captures code snippets, slides, and diagrams exactly as they appear on screen, even when captions are disabled. Transcript-only tools simply cannot see any of that.
Locally and privately. HoverNotes is local-first: your notes and timestamped screenshots are saved as plain Markdown directly to your computer in your Obsidian vault. Nothing is stored in the cloud, so your notes stay yours.
