LightPDF

LightPDF, launched back in 2015, was designed to tackle the everyday struggles people face with PDFs. While researching this tool, I’ll admit I was a bit confused at first about where to find the Chat PDF feature. To my surprise, it’s super versatile—you can access it in their app, or directly on the web. That makes it incredibly accessible, no matter how or where you’re working.

LightPDF, in addition to being a versatile PDF tool, also functions as a handy Chrome extension that makes it even more convenient for digital marketers and other professionals. The ability to use LightPDF directly within your browser streamlines the process, saving time and effort by eliminating the need to switch between multiple apps or tabs.

With this Chrome extension, you can open PDF files directly in your browser, use basic AI features like summarizing text, extracting key points, and compressing documents—all while working on the go.

Features:

• Extracts text from images and scanned documents.

• Connects with Google Drive and Dropbox for easy file access.

• Reduces the size of large PDF files for easier sharing.

• Supports multiple languages for global use.

• Primarily supports PDF files, other formats may not be fully supported.

• Editing options are basic compared to other advanced tools.

• Complex layouts may not convert perfectly.

User Guide:

Before we get into the steps, I’d recommend downloading the LightPDF app for a smoother experience. Honestly, the online Chat PDF feature felt a bit less efficient compared to the app version. Once you’ve installed the app on your system, here’s how you can use the Chat PDF feature:

Step 1: Open a PDF using LightPDF and hover over the LightPDF widget on the right. You’ll see a bunch of options appear—click on the “Chatdoc” button.

Step 2: The Chatdoc panel will open on the right-hand side, giving you a quick summary of your PDF along with some suggested questions to explore.

Step 3: You can either click on the suggested questions or type in your own to interact with Chatdoc and better understand your PDF’s content.

For a clearer view, here’s a step-by-step flowchart of the process.

Effect Preview:

During my experiment with reading a book using LightPDF, I was able to open the document directly in my Chrome browser, making it incredibly efficient. However, despite its accessibility and ease of use, LightPDF's AI features felt somewhat basic. The tool was useful for quickly getting an overview of chapters, summarizing text, and providing general insights into the content.

Chatdoc within the app is definitely a handy feature—it provides references and even pulls quotes directly from the PDF, which is super useful. But honestly, I felt the interface was a bit outdated, and the AI capabilities could use some work. Compared to other tools on this list, I expected it to perform on par, but it fell short in a few areas.

For example, when summarizing a document, it gave me two separate summaries instead of one cohesive overview. Plus, there were slight glitches, like delays in responses and inconsistencies in how it handled queries. Overall, it’s a decent tool to use, but it doesn’t quite match up to the efficiency of some of the other options available.
