OnBinder
Listen
Articles with a prepared audio file can be played with an AI voice. The sentence being read is shown like a subtitle, and you can tap a sentence to play from there or change the playback speed.
Features
Everything you can use on OnBinder to read, listen, save sentences and keep up with new articles, gathered in one place.
Reading tools
Use them from the reading tools box at the top of each article, or from the bar that appears at the bottom of the screen while you read.
Text view
Shows only the text, without ads or images. Paragraphs are highlighted one by one at reading pace, and you can change the speed or download the article as a text file.
Large text
Makes the text larger and the colors sharper. Choose from three sizes (small, medium, large); the setting is remembered in this browser and carries over to other articles.
Sentence highlights
Select a sentence in the article by dragging (or long-pressing on a phone) and a toolbar appears. Signed in, you can save it to My highlights and add a note; anyone can copy a link that points straight to that sentence. Sentences saved by two or more readers are collected under Popular highlights at the end of the article.
Bottom bar
While you read, a bar appears at the bottom of the screen so you can open reading tools such as text view and large text, or share, like and comment, without scrolling back up. It steps aside at the start and the end of the article.
Read with confidence
Each article states how it was made and checked, and how to cite it.
Verification
The verification box under each article explains how it was checked, such as human review, figures corrected against source data and AI cross-checking of translations.
Sources and citation
Check the reuse terms under each article and use Copy citation to copy a citation that credits the source. We welcome search indexing and AI citation with attribution.
External link notice
When a link in an article leads to another site, we tell you where it goes before you leave.
Finding articles
Find something to read and switch to the view that suits you.
Categories and tags
Browse articles by type (category) and by detailed topic (tag). Tapping a tag under an article takes you to articles on the same topic.
Binder
A space where articles on a theme are gathered so you can read them one after another, like a blog.
Sites
Topic sites that gather articles on one field. Some sites also offer tools for that field.
List view
Choose between scrolling continuously through the article list or moving page by page. Your choice is remembered in this browser.
Four languages
Available in Korean, English, Japanese and Spanish. Switch the language at the top of the screen; articles not yet translated into your language are shown in their original language.
Dark mode
Switch between a light and a dark screen with the button at the top of the screen.
