Common Questions
What is Highlighter?
Highlighter is a place for collaborative book discussions. We're a community of authors and readers who see reading as an active, participatory dialogue. Highlighter is also a personal knowledge bank: you can save the best ideas from your books to your own library.
What can I do on Highlighter?
In short: read better, together, and find what to read next.
  • Speak with authors and readers live (in video town halls) or asynchronously (on book hubs).
  • Follow other people to see what they’re reading and which ideas they’re pondering
  • Create a personal library of your highlights & annotations
  • Find what to read next!
What devices can I use Highlighter with?
Anyone can access Highlighter on the web. iPhone users can also use our beta app— Join the waitlist to request access.
How it works
How do I highlight a passage from something I'm reading?
To Highlight from a text, you’ll need the Highlighter iOS beta app, which we have given to some early members. Email us to request access at
On the app, you can take a photo of any text and use your finger to highlight and annotate an interesting idea. You can save your ideas to the book page to interface with others reading the same book, or keep it private for your personal knowledge bank.
What types of content can I Highlight from?
You can Highlight from any type of written text in digital or analog form, including books or e-books. Simply take a photo of the text, annotate, and save it to your digital library.
What does it mean to publish a Highlight?
Publishing a Highlight means saving it to your digital library. By default, your Highlight is publicly visible to all members following the book that it came from. However, you can always choose to make your Highlight private before publishing it.
What’s the difference between a Highlight and a Post?
Highlights and Posts are both ways of discussing books together. A Highlight is an annotation tied to a specific section of text. A post doesn’t have to tie back to a section of text. (Right now, you can only make Highlights using our beta iOS app.)
Why does Highlighter require real names?
Why does Highlighter require real names? Highlighter is a place for people to read and discuss ideas. We require real names to promote thoughtful, high-quality discussion and discourage trolling, spamming, and other forms of harassment.
Why do I have to provide my phone number to create an account on Highlighter?
We are building an authentic discussion forum for real people. We require phone numbers to discourage users from creating multiple accounts with misleading identities.
The Highlighter Waitlist
What is the Highlighter waitlist?
The waitlist is where you can request access to Highlighter’s website and iOS app, which is currently still in beta. The Highlighter iOS app includes the ability to capture and annotate Highlights.
Can anyone join the waitlist?
How does the waitlist work?
We invite readers on the waitlist to (A) create a Highlighter web account and (B) if applicable, join our iOs test app. The best way to skip the waitlist is to register for an upcoming Highlighter Live event.
How can I download the Highlighter beta iOS app?
Once we send you an invite to download the Highlighter beta iOS app:
  1. Download the TestFlight app from the App Store.
  2. Use the link in the email you received from Highlighter to install the beta app.
