Wikipedia Preview


Wikipedia Preview brings free knowledge to your site in the form of a Wikipedia article preview popup. With Wikipedia Preview, a reader can see a short summary of words or concepts in your content by hovering or tapping on the preview popup, as they read through your content page.

Wikipedia Preview is an official plugin developed and supported by the Wikimedia Foundation.

The plugin is entirely free to download and implement as it serves our non-profit’s mission to provide free knowledge for everyone.


  • Leverage an enormous collection of free knowledge to provide context immediately when your readers are curious.
  • Enable users to stay engaged by giving them context while they read.
  • Available in over 300 languages, so you can provide, where available, context in a language different from your site.
  • No need to explain a concept that is not directly related to the article you are writing, add a contextual popup instead.
  • Use the same process you use today to add hyperlinks to your articles or use the Gutenberg editor custom tool.


  • Handles any link to a Wikipedia article regardless of language, lead image presence or length.
  • Works for Right-to-Left (RTL) and Left-To-Right (LTR) languages.
  • A built-in gallery to dive into article images.
  • Can be disabled for any page using the post metadata sidebar. Look for the Wikipedia Preview section.
  • Gutenberg editor custom tool to search for Wikipedia articles and visualize Wikipedia Preview for readers.

How to use

After you download and install the Wikipedia Preview plugin, simply add a link in your site content to any Wikipedia article URL and it will be turned into a preview.


  • Mobile view on touch
  • Mobile view expanded
  • Fullscreen image gallery

Is Wikipedia Preview free?

Yes, Wikipedia Preview is free. It has been made available to you by Wikimedia Foundation, the nonprofit that powers Wikipedia with a mission of free knowledge equity.

Does Wikipedia Preview work on any word?

The Wikipedia Preview works with any word or phrase that has an article on Wikipedia, in any of the available languages.

What is the flow for implementing the Wikipedia Preview links in a post?

When writing articles, decide which words show a Wikipedia popup on a particular post. The process of enabling the Wikipedia popup on a specific word is identical to adding a hyperlink.

After the implementation of Wikipedia Preview will there be any impact on the size of the page? Will it get laggy?

The words that will have a Wikipedia Preview popup on your site need to be annotated. Those annotations add to the page size but not more than the regular hyperlinks you already use.

Is it compatible with all the browsers?

The Wikipedia Preview is compatible with the following browsers: Chrome, Firefox, Opera, Edge (Current and previous version), Safari 5.1+, iOS 6.1+ and Android 4.1+

Depuis que je test cette option permettant l'affichage d'extrait de Wikipédia je n'ai rencontré aucun problème. Mon avis : à tester.
I use quite a few Wikipedia links on my ancient history/languages website and idly wondered if there was a Wordpress plugin which could imitate the preview tooltips which have been on Wikipedia for a while now. This is that plugin. Hopefully the Wikimedia Foundation will keep this updated from time to time. I normally donate £5-10 when their fundraising campaign comes round. Next time I will add another £20, as that is the least I would've paid for a third party app.
We really liked the Wikipedia preview plugin as it provides extra contextual information to our readers without leaving our website. It would be great if some value proposition was offered along with this. Also, sometimes it's difficult for the users to differentiate between Wikipedia preview and hyperlinks.
Wikipedia Preview provides great resources for both educators and learners. The Preview is simple and easy to use. This is a good move towards ensuring education resources are accessible to everyone.
