You can enable a tooltip that shows info about user/author when you rollover/click on related avatar.
Let’s speak clearly: if you are loooking for a plugin that enables the standard Gravatar hovercards, this is not the plugin right for you. Please look for another one.
When you rollover/click on an avatar (e.g. of a comment author), a tooltip popups and shows:
<ul>
<li>some additional links if the author is a registered user: e.g. to user post archive, to user external website, to user blog (if multisite)</li>
<li>some info from Gravatar if author is registered to that service: e.g. location, “about me” description, websites, other account pages (facebook, twitter….)</li>
</ul>
In plugin settings you can set up the javascript and css main options.
The plugin comes with some filter hooks, so you can customise the tooltip content at all.
The plugin uses <a href="http://craigsworks.com/projects/qtip2/" rel="nofollow ugc">qTip plugin for jQuery</a>.

Avatar Tooltip

To show a tooltip with info (member info and Gravatar profile) when you mouseover/click on an avatar.

Responsive Tooltips for WordPress: 
Tooltips are those helpful pop-up boxes that appear when someone hovers over a word, image, button, or any element on your site. With this plugin, you can turn almost anything into an interactive tooltip — text, photos, audio, video, Google Maps, QR codes, GIFs, PDFs, Wikipedia previews, YouTube, SoundCloud, and much more.
Whether it’s a word inside a blog post, a menu item, a WooCommerce description, an ACF field, a comment, or even an image in a gallery, your visitors can get extra information instantly without leaving the page.

<h3>🌟 A Friendly, All-Purpose Tooltip Solution</h3>
When a visitor hovers over a tooltip term, a clean, responsive popup appears. Inside that tooltip window, you can place text, images, videos, audio players, buttons, social icons, PDFs, or any HTML you like using the standard WordPress editor.
You’re in full control. Manage all your tooltip terms and content from one easy admin panel. Add a keyword, write your content (or embed media), and the plugin will automatically detect and display that tooltip anywhere the term appears in your posts, pages, tags, menus, products, or other supported areas.
✨ [Detailed Feature List](<a href='https://tooltips.org/features-of-wordpress-tooltips-plugin/' rel="nofollow ugc">Tooltips for WordPress Features</a>)
<h3>📝 Shortcodes You Can Use When You Want More Control</h3>
You almost never need shortcodes, because detection is automatic — but shortcodes are available for maximum flexibility:
<h3>Basic Tooltip</h3>
[tooltips keyword=”Tooltips for WordPress” content=”A powerful, feature-rich tooltip plugin.”]
Or:
[tooltips content=”A powerful tooltip plugin.”]Tooltips for WordPress[/tooltips]
<h3>Tooltip by ID (Ideal for Page Builders)</h3>
[tooltip_by_id tooltip_id=”222″]
<h3>📘 Built-In Glossary & Directory System</h3>
Tooltips for WordPress includes a complete glossary/directory feature. Just add [glossary] to a page and you instantly get a dictionary-style list of all your tooltip terms—with optional images, alphabetical navigation, SEO-friendly index pages, and multi-language support.
You can display beautiful directories anywhere on your site using simple shortcodes: 
• [productdirectory] – shows a clean WooCommerce product directory 
• [joblistingtable] – lists jobs from the WP Job Manager plugin 
• [member_directory] – creates a friendly member directory 
• [postdirectory] – displays a post list on your wordpress site
If you use popular gallery plugins like NextGEN, tooltips will automatically appear for gallery image descriptions—no setup required. The plugin also works beautifully with Elementor, WPForms, TablePress, Contact Form 7, WooCommerce, ACF, pricing tables, and many more.
