Cubox Review: Finding Top-Notch PDF Reading Options

Numerous digital readers and language enthusiasts encounter difficulties in locating a structured platform for reading and handling their documents. With countless apps and tools available, users frequently feel daunted by complex interfaces and restricted customization choices. Hence, the continuous search for a solution that simplifies reading while preserving functionality can be tiring.

Cubox addresses these requirements by offering a cohesive reading experience with tools aimed at boosting productivity and organization. Although it provides a smooth integration of your reading resources in a single location, it possesses its advantages and disadvantages.

Keep reading this article to find out how Cubox fares in both of these areas. Plus, we'll introduce you to an alternative tool, UPDF, that could elevate your reading experience even better.

Part 1. An Overview of Cubox

To gain a better insight into how this tool improves your workflow, let's explore its main features and observe how it simplifies the process:

What is Cubox?

It is a reading and studying tool powered by AI intended to improve the ways users gather, read, and handle digital content. The tool enables people to save articles/webpages, mark text in different colors, and jot down notes, which facilitates organization and preserves significant information for future reference. Cubox AI offers a cohesive reading environment with customization, nested folders, and integration with tools like Notion and Readwise.

Is Cubox Free?

It operates on freemium models, which provide basic features like saving articles, highlighting text, and organizing content with limited annotations per page. Cubox is not entirely free and offers you various pricing plans with a 14-day free trial. However, with 2 subscription plans, you can get Cubox Pro and Cubox Pro+AI with the following amounts:

• Cubox Pro: $39/year (Does not contain any AI features)
• Cubox Pro+AI: $69/year (Contains all non-AI and AI features)

The Cubox Reading Experience: Strengths and Shortcomings

If you are wondering, are what makes Cubox stand out and where it might fall short, let's learn both its pros and cons to get a clearer picture:

Strengths

• AI-Powered Insight: Cubox Al Reading assistant uses advanced language models to provide automatic summarization, key point extractions, and question answering. This feature helps users quickly digest articles and focus on the most relevant information. Users can interact with the AI as it lets them select the text and click the AI star icon to receive tailored insights.
• Explain Articles: The AI assistant of this tool offers an Explain feature that gives a detailed explanation in easy words. Then, you can use that explanation to “Add to a Highlight Note” folder or “Add to Card Description” as needed. It also helps users get an idea of more questions so that the information within the document can be understood better.

• Customizable Reading Interface: It has the ability to modify fonts, themes, and layout options to establish a distraction-free reading space suited to their tastes. Cubox offers Dark and Light modes, allowing you to tailor the interface according to your preference.
• Advanced Organization Tools: Features like nested folders, tags, and smart folders enable users to categorize and retrieve information.
• Annotation System: Cubox integrates itself with coherent annotation features which starts from smart highlighting. Instead of manual highlighting, Cubox influences an easier model to highlight important data within the document. It also provides a system of easy note-taking and editing, making the commenting process simpler.

• Prepare a LinkedIn Post: While reading content, if you find something interesting, you can choose this feature to generate a LinkedIn post in seconds.
• AI Ghost Highlight: The AI Ghost Highlight feature automatically identifies and highlights important sections within articles, ensuring users don't miss critical information. This functionality is beneficial for skimming through lengthy texts and pinpointing key takeaways.
• Content and Webpage Snapshot: The tool offers smart content parsing, extracting the main body of articles while removing advertisements and irrelevant sections. Additionally, it provides webpage snapshots, preserving the content's layout and appearance for offline access. ​

Shortcomings

• Cubox often suffers from persistent bugs that lead to frustrating login failures and frequent network errors, disrupting the overall user experience.
• The tool consumes a high amount of system resources, which can significantly slow down the performance, especially on older or less powerful devices.
• Unlike UPDF, it does not properly operate when you upload a PDF or document, and it is beneficial only for web-based content.  

• Its keyboard shortcut systems sometimes clash with other applications, which causes unexpected behavior and makes multitasking more difficult.
• While it is a feature-rich tool, it is overly complex, with a dense interface and options that may overwhelm users.
• With the limited File storage for large files, it offers 5 MB in the basic account and 20 MB in the premium account.

Now, these limitations might be pushing you to consider a better Cubox alternate. That’s why we’ll dive into UPDF in detail in Part 2, which offers an innovative solution to all these challenges. So, download the UPDF now and explore what it offers that makes it a better option than this one.

Supported File Types

Before that, let’s give this tool a chance and take a quick look at the types of files Cubox supports.
