Complete Step-by-Step Guide On How To Use Unriddle's AI Research Tool

Here is a step-by-step guide on how to use Unriddle. I’ve also copied it below :)

From here, it's pretty simple.

Unriddle helps you read, write and learn faster.

Interact with documents via AI so you can quickly find and understand info.

Then start writing in a new Note and Unriddle will show you relevant content from your library as you type.

Get started by uploading a document.

Or read on for the full rundown.

Interact with documents

When you upload a document, Unriddle generates an AI assistant on top of this data.

Click 'New' in the right sidebar and then select 'Upload' to get started.

Use this assistant to answer specific questions about the text, summarize content and simplify jargon.

The trick is to be super clear about what you want.

If you're summarizing a research paper, for example, instead of saying “Summarize” or “Summarize this research paper”, say something like “Explain this research paper to me in simple terms. What method did the researchers use? What did they find? Why does it matter?”.

The second prompt will produce a much better overview of the paper because we're giving the AI more hints about what we want.

Automatic relations

Unriddle grasps the context behind each Note and Document in your library and automatically links them based on meaning.

Let's say you have a collection of nuclear physics papers in your library.

When you start writing a note about The Manhattan Project, simply mentioning "The Manhattan Project" will prompt Unriddle to find the connection between this note and the nuclear physics papers.

Even if you didn't explicitly mention the research papers, Unriddle's knowledge of Oppenheimer, his work, and the significant relevance of these papers means it understands the connection and automatically links them together.

In short, Unriddle shows you relevant content from your library at the exact moment you need it, even if you haven't explicitly mentioned it.

Citing your sources

Writing is hard when you have a ton of sources to track.

So we made it easy.

Highlight some text, click ‘Cite’ and you’ll see items from your library that contain information related to the selection of text you just highlighted as determined by our AI.

When you select an item Unriddle inserts a link into highlighted text that, when clicked, takes you to the referenced item.

Writing with AI

Click ‘New’ in the sidebar and hit ‘Note’ to open up a new note.

Here you’ll find all the text formatting options you’re used to and more.

Type ‘++’ to generate text based on the context of what’s already written.

Highlight text and click ‘Ask AI’ to open up the AI menu where you’ll find options to improve, expand, summarize and explain.

You can type custom prompts too!

Finally, you can open any note in a pane on the right side of the screen while interacting with documents. Just click the orange pencil icon at the top of the chat window.

Chat Settings

Adjust the model, temperature and response length in the Setting sidebar.

Click the cog icon in the top right corner of the screen and look for "Chat Settings".

These apply across all documents but you can easily flip between them regardless of settings at the time of upload.

Model: the machine learning model used to generate responses.

Temperature: the amount of creative license you give to the AI.

Max length: the maximum number of words generated in a response.

Got feedback or questions? Send us an email and we'll get back to you within a day.
