Features Tooltivity's expert score for the 'Features' aspect of each extension. | 9.5 Grammarly goes beyond basic grammar and spelling checks. It offers advanced features like tone detection, vocabulary enhancement, and generative AI capabilities. Compared to competitors, Grammarly provides a more comprehensive set of tools, making it a valuable asset for any writer. Winner in this category | 8.8 Instapaper's feature set is impressive in its core functionality. The service excels at its primary purpose of saving and reading web content offline. The text view feature provides an excellent reading experience, stripping away distractions and presenting content in a clean, readable format. The highlighting and note-taking capabilities are useful tools for active readers, though they could benefit from some refinement. The Kindle integration works seamlessly, making it easy to transfer articles to your e-reader. Mobile apps offer reliable synchronization across devices, ensuring your reading list is always up to date. However, the service lacks some modern features like social sharing that competitors offer. The search functionality in the free tier is somewhat basic, and customization options are more limited compared to other services in this space. ![]() |
Performance Tooltivity's expert score for the 'Performance' aspect of each extension. | 9.0 Grammarly performs well across different platforms, providing real-time suggestions without significant lag. The tool is reliable and helps improve writing efficiency. Winner in this category | 8.0 Instapaper’s performance is strong overall, but the initial setup leaves much to be desired. After installing the Chrome extension, there was no response or prompt—no indication that any further action was needed. It wasn’t until we read a user review that we realized we had to manually visit the Instapaper website and log in. Without that information, we likely would have assumed the extension was broken and uninstalled it. Once past that rocky start, however, the service works reliably. Web pages save quickly, and saved content loads without issue. Offline access is stable, and synchronization across devices keeps your reading list up to date. The mobile apps offer smooth performance and quick navigation, while the text view provides a responsive and comfortable reading experience. The search function is usable, though slightly slow at times. Despite the poor onboarding, Instapaper delivers solid functionality once everything is properly set up. |
Design Tooltivity's expert score for the 'Design' aspect of each extension. | 8.5 The design is clean and intuitive, making it easy to navigate. The color-coded underlines for suggestions are helpful, and the interface is user-friendly. However, some users might find the pop-ups slightly intrusive. Winner in this category | 8.5 The design of Instapaper focuses on simplicity and readability. The interface is clean and minimalist, putting the content front and center. The text view is particularly well-designed, offering a comfortable reading experience with good typography and spacing. The mobile apps follow their respective platform design guidelines, providing a native feel on both iOS and Android. The browser extension maintains this simplicity with a straightforward interface. However, some UI elements feel dated and could use a refresh. While the reading experience is consistent across platforms, the navigation could be more intuitive in some areas. The limited customization options might disappoint users who prefer more control over their reading environment. Winner in this category |
Value for Money Tooltivity's expert score for the 'Value for Money' aspect of each extension. | 8.5 While Grammarly offers a free version, the Premium plan is relatively expensive. However, the advanced features and comprehensive feedback justify the cost for those who need a robust writing assistant. Grammarly is the priciest option for a reason—because, in our view, it's the best writing tool available in its category. If you're looking for the best writing assistant, go for the Premium plan, you won't regret it! Winner in this category | 8.0 The pricing structure of Instapaper offers a basic free tier that's functional but limited. The premium features are reasonably priced, offering good value for heavy readers. The pricing is competitive compared to alternatives in the market. However, some features that are currently premium could potentially be included in the free tier to provide more value to basic users. The annual subscription offers good savings for committed users. While the premium features are well-implemented, the free tier could offer more value to attract new users and provide a better experience for casual users. |
Ease of Use Tooltivity's expert score for the 'Ease of Use' aspect of each extension. | 9.0 Grammarly is straightforward to use, with a minimal learning curve. The browser extension integrates seamlessly with various platforms like Google Docs and Gmail, allowing you to get started right away. Winner in this category | 7.0 Instapaper’s setup process is not beginner-friendly. After installing the browser extension, there was no response or guidance—no prompt, login window, or confirmation. We had to manually visit the website and log in, something we only discovered thanks to a tip in another user’s review. Without that, we likely would have uninstalled the extension, assuming it didn’t work. However, once logged in, the service functions smoothly. Saving content is quick, the interface is clean and intuitive, and managing your reading list is simple and efficient. |
Security & Privacy Tooltivity's expert score for the 'Security & Privacy' aspect of each extension. | 8.0 Grammarly takes privacy seriously, with stringent security measures in place. While an account is required, the company assures users that their data is not sold or made public. However, some users may still have concerns about data processing. | 9.0 Instapaper takes user privacy and security seriously. The service maintains a clear and transparent privacy policy, explicitly stating that user data is not sold to third parties. The company has demonstrated a strong commitment to user privacy through its GDPR compliance and Privacy Shield certification. Data storage is secure, and the service regularly updates its security measures. The data collection practices are transparent, with clear explanations of what information is collected and how it's used. This high level of attention to privacy and security makes Instapaper a trustworthy choice for users concerned about their data. Winner in this category |
Conclusion A summary of our findings and final thoughts for each extension. | In our eyes, Grammarly is the best choice for anyone who wants to write professional articles or other things in English. Even though Grammarly has an expensice price tag, you can't get anything better on the market. We have been using Grammarly for a long time now. And even in the world of ChatGPT and other AI tools, Grammarly is just super handy and helpful. For us, the Premium plan is worth every penny.

Recent issues with the Chrome extension and some user complaints about the save feature need to be addressed, but the core service remains stable and useful. For users who appreciate a simple, straightforward approach to saving and reading web content, Instapaper remains a good choice. However, those looking for advanced features or a more modern interface should look for alternatives. |
