Of note: this tool is integrated into AccessMedicine and AccessPhysiotherapy. When in a chapter, click annotate to prompt Hypothesis to open. See the example below.

Annotating with Hypothesis

Hypothesis is a free online tool designed to allow for collaborative annotation across the web. This guide will walk you through using Hypothesis with the Chrome extension. To use the bookmarklet in another browser, please refer to the hypothesis user guide for step-by-step instructions.

It can be used to annotate web pages, PDFs and EPUB files. You can annotate documents and pages publicly, privately, or within a group.

To get started with Hypothesis you'll need to:

• Create an account. 
• Install the Chrome extension or the Hypothesis Bookmarklet if you are using a browser other than Chrome. 
• Start annotating!

What makes Hypothesis different than other tools is that you can annotate PDFs as well as web pages. It also allows for group and collaborative annotation. 

• Create a Hypothesis Account
• Chrome Extension
• Hypothesis User Guide

Opening Web Pages and PDFs

Navigate to the web page or pdf in your browser. 

Next, select the Hypothesis icon located in the right corner of your Chrome browser if it is not already active.

 An inactive icon will appear as light gray, and if it is ready to use it will be black. If you have not used Hypothesis for a while you may need to log in to activate the program.

Once Hypothesis is active on a page you can start annotating. You can highlight text, add annotation, add a note for the whole page, share the page with others, and reply to other comments on the page. You may have to click the toggle arrow to see options, comments, and notes.

Adding Annotation and Highlighting Text

To highlight or add annotation for certain text, simply select the text and the highlight and annotation icons will appear.

To create a note for the entire page, select the note icon that appears on the Hypothesis menu on the right side of the screen. You can also toggle highlighted text on and off using the eye icon.

Formatting Annotation

Once you have selected text to annotate, an annotation box will appear in the menu on the right. The annotation section allows you to perform minor formatting of text such as bold, italics, quoted text, lists, links, and even mathematical notation that is LaTex supported.

There is also an option to add web links and links to online images and videos. Images will appear and videos will play right in the annotation section of the page. 

Adding Tags

You may also add tags to your annotation to better organize your idea and thoughts, and categorize content. To learn more about tags and how they can be used to enhance collaboration and search, please see the Using Tags Tutorial .

Public, Private, and Private Group Annotation

Annotations, notes and highlights can be made public, private or shared within a specific group. All annotation setting default to public unless you choose another option. Public annotations can be seen by anyone who visits the webpage or pdf and has Hypothesis enabled.

Switching from Public to "Only Me"

If you would like to make notes private where only you can see them, be sure to select the Only Me  option in the annotation box.

Once you have selected this option, all other annotations, highlights and notes will default to private on the page and be shown with a lock icon next to your name. To switch back select the Public option.

Private Groups

To share annotations with a group you have already created or have been invited to, select the down arrow next to Public  in the Hypothesis menu. Here you will see any private groups you belong to as well as an option to create a new private group. Selecting a group will allow you to annotate and have only the members belonging to the group view and respond to your comments, highlights and notes. 

To create a new group, select the + New Private Group option. From here you will be taken to a new screen where you will be asked to name the group. Click the Create group button to create the new private group.

Once the group is created, you will be given a link to share to invite new members to the group.

Annotating a Locally-Saved PDF 

To annotate a saved pdf in Hypothesis, open it in your browser. Once it is open in your browser activate Hypothesis to start annotating. The pdf must have selectable text in order for Hypothesis to work. If you have issues with this feature, consult the annotating locally saved pdfs tutorial .

Installing the Bookmarklet

For those who use Firefox, Safari, and other browsers, our Bookmarklet provides an easy way to use Hypothesis in the browser of your choice.

If your preferred browser is Chrome (or another Chromium-based browser), please see these instructions for installing the Chrome extension .

For most browsers (except mobile devices)

To install the Hypothesis Bookmarklet, open the browser of your choice and drag the Hypothesis Bookmarklet button below to the bookmarks bar, or right-click/control-click to bookmark the link.

To start annotating, visit any web page, open your Bookmarks toolbar, and click “Hypothesis Bookmarklet.” The Hypothesis sidebar will appear over the page.

For browsers on mobile devices (including iPads)

To install the Hypothesis Bookmarklet you’ll make a bookmark in your mobile browser out of any page, and then edit the bookmark, replacing the URL with some javascript we specify below.

To install the Bookmarklet

• In your mobile browser, on any webpage, create a bookmark.
• In your browser settings edit the bookmark.
• Change the name of the bookmarklet to “Hypothesis Bookmarklet”
• javascript:(function(){window.hypothesisConfig=function(){return{showHighlights:true,appType:'bookmarklet'};};var d=document,s=d.createElement('script');s.setAttribute('src','https://hypothes.is/embed.js');d.body.appendChild(s)})();

To use the Bookmarklet

• Navigate to a site you want to annotate.
• In the browser URL bar (not the Bookmark menu) type “Hypothesis Bookmarklet”
• Select the text that appears in the URL bar.

You should remain on the site you want to annotate and the Hypothesis Sidebar will appear!

A Teacher's Guide to First-Year Writing

Baruch college first-year writing program, next, add hypothesis to your browser..

How you add Hypothesis to your browser depends a little bit on which browser you use. You’ll notice that on the Getting Started page there are two options, one exclusively for Google Chrome. 

If you are a Chrome user , you can simply click that button and follow the directions to add the Hypothesis Extension to your browser.

Notice that you will be prompted to share information with Hypothesis, but they’re an open-source-minded group and aren’t likely to do bad things with your data (can’t say the same about Google itself). This will add a button to toggle Hypothesis on and off on your computer. To make sure the button is activated on Chrome, click the puzzle-piece icon in the top right-hand corner of your browser and “Pin” Hypothesis (make sure the push pin icon is clicked to turn dark blue). You should now see a small button with the Hypothesis logo next to the puzzle icon. Clicking the Hypothesis button will toggle Hypothesis on and off for any website.

If you use a browser OTHER than Chrome (Firefox, Safari, Microsoft Edge, Internet Explorer, Opera, etc.), then you’ll need to add a “Bookmarklet” to use Hypothesis. This is a simple step.

Notice from this screenshot how I have a “Bookmarks Bar” on my Safari browser (and similarly would if I were using these other browsers). If you can see your Bookmarks Bar as I can, click and drag the Hypothesis Bookmarklet box from the Getting Started page onto your Bookmarks Bar. (Note: This box isn’t exactly a link, but a bit of code, so you’ll need to use click and drag—saving the link as a Bookmark won’t work). A new link should show on your Bookmarks Bar: Hypothesis Bookmarklet. You can rename this link or drag it to the desired location on your Bookmarks Bar. Clicking that bookmark link will toggle on and off Hypothesis on any website.
