| Features Tooltivity's expert score for the 'Features' aspect of each extension. | 9.8 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 Highlights1. 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:
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. Winner in this category | 8.8 The AI writing aid worked very well in the test with emails, customer responses, and short formats. We particularly liked the dynamic templates, which adapt according to user input. The extension can therefore be adapted for both commercial use, such as quickly replying to emails, and for everyday private use. From summaries to social media texts, this helped enormously in the test. In particular, learners such as students should have a special added value here, for example, through summaries that can be created quickly.

| Performance Tooltivity's expert score for the 'Performance' aspect of each extension. | 10 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. Winner in this category | 8.9 In our test, AI Blaze worked reliably on most websites and in various applications. The only thing that was immediately noticeable at the beginning was that the functions do not work in the Chrome Store, so websites may prevent access for the extension, but this did not otherwise occur in the test.  The text expansion works immediately, and the AI-controlled functions generally respond quickly, depending on the model selected. When using the most advanced AI models for complex tasks, there were occasional short delays, but these were minimal. |
| Design Tooltivity's expert score for the 'Design' aspect of each extension. | 9.9 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. Winner in this category | 8.8 The clear, intuitive user interface should also make AI Blaze possible for private users who are not so tech-savvy. The integration into the sidebar is very well done and offers a seamless integration into the design of the browser. |
| Value for Money Tooltivity's expert score for the 'Value for Money' aspect of each extension. | 9.5 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. Winner in this category | 9.0 In this area, a clear distinction must be made between private and commercial users. For the private user, AI Blaze already offers enough functionality for most people in the free plan. Here we also appreciate the Academic Edition, which offers students and teachers extended, free access. The Pro plan could be too high for private users at $20/month with annual billing. For businesses, however, AI Blaze's Pro plan offers exceptional value compared to similar productivity tools. The time savings alone can justify the investment for most users. For those who want to work in teams, AI Blaze offers the Business plan for $24/user/month. This includes additional comprehensive functions for collaboration and improved communication processes. Compared to alternatives, AI Blaze offers a competitive feature set at a reasonable price for businesses. The ROI is clear after just a few days of regular use, especially for those who frequently write similar messages. |
| Ease of Use Tooltivity's expert score for the 'Ease of Use' aspect of each extension. | 9.5 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. Winner in this category | 9.0 For basic functions such as using templates and simple shortcuts, AI Blaze is extremely straightforward. New users can start using the ready-made templates within minutes, and they are well-explained. If you don't want to use the predefined shortcuts, you can create your own commands immediately, which makes it easier to remember the shortcuts in everyday life. We found the shortcuts intuitive and time-saving once you have memorized them. The search function makes it easy to find the right snippet quickly, even as the library grows. The advanced functions do require a certain amount of learning, but the basic functions are easily accessible straight away. |
| Security & Privacy Tooltivity's expert score for the 'Security & Privacy' aspect of each extension. | 9.9 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. Winner in this category | 9.7 AI Blaze takes security very seriously and holds a SOC 2 certification, which confirms that a company has implemented appropriate controls and procedures for IT systems, data protection, and data security. The company's privacy policies are transparent from the user's perspective in terms of how data is handled, and no user data is sold to third parties. The Business and Enterprise plans offer additional security features such as SAML SSO integration and audit logs. Choosing between different AI models gives users more control over their data. The company is transparent about its use of cookies and analytics and provides clear options for managing settings. There is also the option to allow the extension only to use marked areas for answers, normally, the AI uses the entire website content to have a better data basis.  |
