Unriddle AI Review

This in-depth Unriddle AI review is a must-read if you’re a student, teacher, researcher, or business R&D professional looking for a reliable AI assistant who speaks your language.

With the crazy onset of artificial intelligence technology, you’ll find AI embedded in many niches like text-to-image, AI profile picture generators, AI help desk software, AI sales tools, and many more.

Among these, an AI summarizer tool like the Unriddle can be a lifesaver. Let me show you why:

What Is Unriddle AI?

Unriddle AI review dashboard

Unriddle AI is an AI-powered tool used for research and writing.

This conversational AI assistant quickly gathers the key points of a text, so you can grasp them in a jiffy. Also, it keeps track of the past skimming of various documents.

If your question requires an in-depth inquiry into those documents, the Unriddle chatbot automatically connects the dots!

You can also ask it focused questions on the text you’ve uploaded and it’ll give you the answers. Whether you’re a student, a researcher, or a professional, this tool can help you learn and research.

At the time of my review, Unriddle AI supports 95+ languages like English, French, Dutch, Spanish, German, and many more.

Unriddle AI Review: Features

Here are the best features and functionalities of Unriddle that help you to read, make notes, and write documents faster using artificial intelligence:

User Interface and Experience

User Interface and Experience

Unriddle AI’s UI and UX offer maximum convenience. Firstly, the user interface is clean, organized, and clutter-free, so there aren’t numerous options on the screen to distract.

Secondly, it divides the app’s useable area into two parts: one showing a preview of the original document you’ve uploaded, and the other one is for the AI conversation.

Should you need a personal note-taking screen, you can simply click on the pencil icon in the top right corner to add a third preview for notes.

All the other options are hidden within the three-line menu in the top left corner and the settings (cogwheel) icon in the top right corner.

Quillbot source doc

Upload PDF/ Markdown/ Text

preview of doc

Unriddle AI lets you upload different types of source documents. These initial documents could be a PDF, markdown file, or copied text from the source. Also, you can directly copy and paste the URL of the source text from a website or document-sharing portal and Unriddle AI will process the content for the Q&A sessions.

Once uploaded, Unriddle displays the document as formatted in the original file and the uploading and preview are almost instant.


When you compare this with the same feature of Paraphraser.io, uploading and processing of the source document fails intermittently. When uploaded, the content shows in basic text without any source formatting of the PDF file.

Generate Text Summary

text summary

The text summary feature works in two ways. You can either write your own prompt in the conversation box or use suggested ones from the Prompts to get you started page.

Unriddle AI generates a high-quality summary of the source text. Also, it adds hyperlinks to the locations on the doc from which it has referred. Moreover, when you interact with the tool for a few hours, the AI adapts to the complexity level you’re comfortable with for text summaries.

Get Answers to Questions

Q&A with ai

This is the most useful feature of the Unriddle AI summarizer web app. You can upload a document Unriddle and ask questions.

The AI skims through the notes and provides accurate answers.

Similarly, if you’re a researcher and want to create quick snippets of answers from a long document for the audience, investors, or business managers, you can make use of this cool feature too. Most of its competitors like QuillBot, Paraphraser.io, etc., don’t offer such a handy feature.

Create Notes

Create Notes

With Unriddle AI you can take personal notes from source documents or the AI’s output. These notes will be available for online access from any device you log into the platform with.

The note feature of Unriddle offers the most necessary text formatting attributes like HTML heading styles (H1/H2/H3, etc.), Bullets, Numbers, Tasks, References, Hyperlinks, etc. Furthermore, you can use the AI Edit feature to make your notes perfect..

All notes

If you’re a teacher, you can use the Export as PDF feature of the Unriddle Notes module to quickly generate hundreds of pages of notes for your students in a few minutes.

Find related content

Often, notes distributed by teachers and professors in your institute may contain discussions on multiple topics. For example, a note on Thermodynamics could cover over 10 topics. However, you’re only focusing on the Internal Energy topic of Thermodynamics.

In that case, you can ask Unriddle AI to aggregate all the content from a large note that only talks about Internal Energy.

You can apply this feature in many other fields like marketing, web scrapping, online research, corporate business report making, and many more.

The related content skimmer isn’t available in Unriddle’s competitors like Paraphraser, QuillBot, Summarizer AI, etc.

Get Help With Writing

Get Help With Writing

You can also use the tool to create high-quality articles. The tool uses the GPT 3.5 and GPT 4.0 models for natural language processing and AI text generation. In the free trial, you can only use the GPT 3.5 model.

You can access the writing feature by choosing the Write module from the dashboard. You must give an appropriate title to the article and write or add the first few lines of the article. Now, you can just type ++ and the AI will take over on your behalf.

Get an Explanation Based on Reading Level

If the summary or answers generated by the Unriddle AI seem too complicated, you can use its Reading Levels adjustment feature to get simpler answers, or vice versa.

You can enter prompts like “Explain this topic to me as if I’m a 12-year-old,” and so on. The conversational AI will automatically change its output according to your reading level.

Translate Text Document

Since Unriddle AI supports more than 95 languages, you can use the AI to translate articles into foreign languages. The output is far better and more accurate than Google Translate.

All the translation work happens with AI prompting.

Get Suggestions on Practise Questions

Get Suggestions on Practise Question

Suppose you’ve done enough mock tests but want to practice on the potentially surprising questions that many exams have.

To get help with that, you could upload notes, textbook pages, research papers, lecture sheets, etc. Then, ask the AI to come up with complicated and out-of-the-box questions from the content.

Here, you can also input the complexity level like questions for middle school, high school, graduate school, and so on.

Chrome Extension

Online AI summary

If you invest too much time doing research online, you can save a lot of time by switching to Unriddle AI’s Chrome Extension.

Once you install it to your Chrome web browser, you can simply highlight a text on a website, right-click, and select the Summarize option to get an instant summary of the text.

This feature will help you aggregate online documents via quick initial screening. If the summary indicates relevant topics, you can save the document for further analysis or simply ignore the website.

Prompt Templates
