Relingo Review: Diving Into The Details

Many language learners struggle to stay connected and motivated, especially when they need to switch between apps, textbooks, and real-life content. Traditional learning methods often feel disconnected from everyday tasks like reading articles, watching videos, or reviewing PDFs for work or study. That is why tools like Relingo have become popular, which let users learn languages in context by transforming everyday web browsing into interactive vocabulary practice.

However, it only focuses on online content, which can limit learners who prefer studying from PDFs. Hence, this guide will cover every feature this tool has to offer, from its strengths to its limitations. So, keep reading this article as we’ll introduce a better alternative, UPDF, which is a perfect solution for document-based learning for reading research papers or study guides.

Part 1. An Overview of Relingo

The following section will cover a detailed overview of the tool and how you can use it in your daily life:

What is Relingo?

It is a language learning tool that comes in both a Chrome extension and an app (iOS|Android). Relingo allows you to integrate vocabulary acquisition into your daily web browsing, making language understanding a seamless part of your routine. By using Google, OpenAI, and DeepL, Relingo Chrome enhances the learning experience and works directly with your web activities. Users can track their reading time and monitor their progress with their reading management system.  

Key Features of Relingo

2. Vocabulary Reinforcement: The flashcard feature in the tool helps you strengthen vocabulary and phrases by reviewing the words you encounter while learning.
3. Level Word Book: You can select from beginner, intermediate, advanced, or proficient level to match your current learning stage. Moreover, it lets you create a folder of everything you learned under All words, Mastered, and Sentences, making it easier to track progress. Furthermore, users can download the folders in an Excel sheet to access and review them at any time.
4. AI-Powered Learning: Using advanced AI, Relingo customizes your learning journey and tailor vocabulary recommendations by focusing on where you need improvement.

Relingo's Strengths in Language Learning

1. Relingo review often highlights how well the tool translates the content by allowing users to upload a PDF and automatically recognize the text. It provides segment-by-segment and full-text translation modes.
2. With its Study Progress page, users can access details about how much time they have spent studying and adjust their study plans accordingly.
3. Whether you are watching Netflix or a YouTube video, you can simply hover over the word to see the translation.
4. The tool gives you complete control over your learning preferences. It lets you customize annotation methods (click or hover), choose highlight styles and colors, and set up your preferred keyboard shortcuts.

Limitations of Relingo in PDF-Based Learning

1. The tool primarily focuses on translating PDFs, lacking comprehensive editing features.
2. You cannot summarize or ask questions related to a PDF using Relingo. Additionally, if you want to edit the text, highlight specific parts, or make direct changes within the PDF, it doesn’t offer those capabilities.
3. Relingo lacks cloud integration, limiting access to documents across multiple devices.
4. If your PDF is scanned or image-based, Relingo does not offer OCR functionality to convert the PDF into editable and searchable text. However, if you wish to manage scanned documents, tools like UPDF provide exceptional results with its multilingual approach.

Step 4. Upon doing so, click the “Open Local PDF” and add your target PDF that you want to translate.

Step 5. Afterward, the tool will automatically translate it into your chosen language and hit the “Download” button to save the translated PDF.

Part 2. Enhancing PDF Learning with UPDF

From the Relingo review, it's clear that while it excels at immersive language learning, it falls short when it comes to deeper PDF interaction. Therefore, you can use UPDF, which is an all-in-one PDF editor. Using the GPT 4.1 and DeepThink R1 model, the AI assistant tool answers your questions related to PDF. You can simply copy the text from a PDF and add a detailed prompt, as well as take a screenshot to communicate.

Additionally, UPDF’s Text-to-Speech (TTS) functionality is available on both Mac and iOS versions, allowing users, especially students, to learn pronunciations while reading foreign language content. With all these features, managing PDFs gets exceptionally easy, while allowing users to perform multiple functions while staying across the same platform.

Key Features

2. OCR: Unlike Relingo, you can even add scanned PDFs to turn them into searchable text with over 38 languages by using the Optical Character Recognition.  

• Q&A With AI: With its DeepThink R1 and GPT 4.1 model, UPDF allows you to engage in interactive chat sessions, providing logical reasoning and precise answers to your questions without needing to upload even a PDF.
• Explain PDFs: If you need to understand a topic, you can also get a detailed explanation by breaking down complex ideas into easily understandable points. Just select a particular point and get an explanation across it within the PDF without any hindrance.
• PDF to Mind Map: Besides translation, the tool enables you to easily convert your PDF into a mind map, which helps you visually organize vocabulary, grammar rules, and study topics.  

• Reader: It lets you read the text smoothly and offers 2 Slide show modes, with a pen and a laser pointer tool, which is great for practicing reading aloud during language review.
• Edit: From its Edit tool, users can import images, text, and even add hyperlinks. This feature allows you to customize your document and make it more interactive with an informative link.
• Annotate: You can also highlight, edit, and even add sticky notes in PDF, which makes it easy to mark essential vocabulary, jot down translations, and leave grammar tips.
