Compare PDF & Web Highlighter and Diigo: Which Extension is the Best?

Web Highlights offers a range of features. In addition to its main function of highlighting text on websites and PDFs, it provides much more, making it the ideal tool for learning and self-improvement.

Top Features of Web Highlights

1. Highlighting websites & PDFs:

Web Highlights excels at one thing better than any other tool we tested—highlighting websites and PDFs.

You don't even need an account. Just visit any site, highlight the text, and a marker icon will appear, letting you choose from different highlight colors.

Once highlighted, your highlights are visible on the website. And the best thing: Your highlights will also be visible on the website if you reload the page.

You not necessarily need the highlighter popup to mark up some text. In general, there are three ways to create a highlight:

• clicking the highlighter popup
• right-clicking the selected text
• using a keyboard shortcut (Mac: ⌥ + S, Windows: ALT + S)

In our tests, we could easily highlight several websites, and those highlights were effortlessly restored when revisiting them. It works seamlessly with both online and local PDFs.

All of your highlights are not only visible on the page but also accessible through the sidebar, which gives you a good overview of your highlights made.

This is much like the highlighter sidebar which is common in PDF tools like Acrobat.

Here is how it looks:

The sidebar gives you an outline of your highlights on the current page.

2. Create Notes & Tags:

You can either create tags & notes by using the sidebar or by clicking on a highlight on the page. This will open up a popup allowing you to add tags and notes to a specific highlight.

Any changes you make on the pages are also directly visible in the sidebar. Making it a perfect research tool to work with large articles.

Inside the sidebar you can then find all your highlights and bookmarks listed for the given tag.

3. Web App:

The best thing about Web Highlights is, that it can synchronize all your research to the corresponding web app at app.web-highlights.com.

The web app can be opened in your browser but works perfetly on your phone. If you have opened the website before, you can even access your research when you are offline.

The dashboard of the app shows all of your research in one place in a beautiful overview. You can also filter for specific tags or websites.

4. Save Bookmarks:

Web Highlights isn't just for highlighting text—it’s also great for saving pages as bookmarks. This way, you can either come back later to continue highlighting or easily find the page again.

5. Email reminders

A standout feature of Web Highlights is its email reminder, which works a lot like "snoozing" emails.

You can set a reminder for a specific date and time by clicking the clock icon on a highlighted page. Web Highlights will then email you the article so you don’t forget to revisit it.

This feature is unique among competitors, and we use it daily to get reminders for websites we need to return to later.

6. Export to Notion, Markdown, and more

Web Highlights gives you plenty of export options. With the Markdown export, you can easily send your research to any Second Brain or PKM tool you prefer.

On top of that, it directly integrates with Notion and Capacities through full API connections.

For instance, if you're on a highlighted page, just click the three dots in the sidebar and choose "Export to Notion." In seconds, a Notion page will be created. The same process works for Capacities.

The extension performs seamlessly, allowing you to highlight websites and PDFs without any lag or interruptions.

The full-text search functionality is quick and accurate, enabling you to find your highlights effortlessly. Additionally, the ability to sync your highlights across devices ensures that you can access your research from anywhere, enhancing your productivity.

The best part is that the web app works entirely offline. So, you can access your research from any device, even without an internet connection.

The design is clean and intuitive, making it easy to get started right away. We loved the customizable highlight colors and the overall look and feel of the sidebar.

What users love most is the intuitive sidebar and the well-organized web app. It’s super easy to navigate and quickly find what you need.

The web app also looks great on mobile devices, making it simple to access the articles you've read on your phone.

Web Highlights can be used for free without signing up, providing access to a wide range of offline features.

To fully enjoy the benefits of Web Highlights, including accessing your highlights and bookmarks from anywhere with automatic cloud-sync, you can upgrade to the PREMIUM or ULTIMATE version of the extension.

The pricing plans are affordable, making it a cost-effective solution for students, researchers, and avid online readers. No other tool gives you this much value for so little cost.

We can’t think of a simpler Chrome Extension to start with than this one. The best part? It works seamlessly right out of the box, no account needed.

Installing it is a breeze, and you can easily add the extension to both Google Chrome and Microsoft Edge.

Once installed, a highlighter pop-up appears whenever you highlight text on any website. The process is intuitive and easy to grasp.

If you need help, Web Highlights offers plenty of blog posts that guide you through its features.

With so many powerful features, Web Highlights might seem a bit overwhelming at first, but everything falls into place quickly. The tagging system, in particular, is easy to use and much simpler than traditional folders.

That’s why we rate it 9.5 out of 10. It’s extremely user-friendly, though some features might take a little time to fully appreciate.

In the Security & Privacy category, we give Web Highlights a solid 10/10. The fact that you can use this tool offline without needing an account sets it apart from its competitors.

Even if you opt for cloud sync by creating an account, Web Highlights puts data privacy first. Your highlights, notes, and tags are visible only to you by default unless you decide to share them.

Your data isn’t sold to third parties, nor is it used or transferred for anything beyond the extension's core functionality. This dedication to data privacy ensures your information stays secure and confidential.
