Turn the Web Into Your Personal Notebook
We've all been there. You're deep into an amazing article or critical piece of research, and you find a flash of brilliance—a perfect quote, a crucial statistic, a key idea. You promise yourself you'll remember it, but a dozen tabs later, that insight is gone.
What if the web wasn't just for reading, but for thinking? Introducing the Internet Markup Tool—a simple, powerful extension that transforms any webpage into your personal canvas.
Engage Directly with Content
Effortlessly highlight what matters and underline key phrases to make them pop. Go beyond passive reading and start actively engaging with information. Have a sudden idea or question? Drop a sticky note anywhere on the page to capture your thoughts in the moment. It’s like having a conversation with the content itself.
Never Lose Your Work Again
Here’s where the magic happens: your work is automatically saved. When you return to a page tomorrow, next week, or next year, all your highlights, underlines, and notes will be waiting for you, exactly as you left them. Your insights become a permanent, valuable layer on top of the web.
Gather Your Research in Seconds
When you're ready to consolidate your findings, the toolbar menu makes it easy. Instantly copy all your marked text to your clipboard, or save the entire annotated page as a PDF. Your scattered research from across the web now comes together seamlessly.
Private and Secure, Always
Work with complete peace of mind. Your markups and notes are your own. They are saved only on your local computer and are never collected or seen by anyone else. That's our promise.
Perfect for:
Students: Turning online articles and textbooks into powerful study guides by highlighting key concepts and adding notes for exams.
Researchers: Effortlessly collecting data, quotes, and sources from across the web and exporting them into a single, organized document.
Writers & Professionals: Gathering inspiration, annotating articles, and saving crucial information for reports, client work, or creative projects.
Curious Minds & Lifelong Learners: Building a personal knowledge base and ensuring that valuable insights from their reading are never forgotten.
Stop just browsing. Start building your personal library of knowledge, one highlight at a time. Add the Markup Tool to Chrome today and never lose a thought again.

- (2025-08-18) Anya Parakh: Incredibly useful tool, particularly for research when I'm annotating multiple papers/articles at the same time. Saves me the time and effort of having to copy down each source while collating research/quotes, and I consequently don't need a thousand tabs open to keep track of my work.
