Description

NavTalk Digital Human is a WordPress plugin that enables you to embed interactive AI avatars on your website. Users can have real-time voice and video conversations with AI-powered digital humans directly from your WordPress pages. This plugin is not affiliated with or endorsed by WordPress.

The plugin itself is free and the full plugin code is included in this package. Avatar and conversation features are provided by the NavTalk cloud service (Software as a Service); a NavTalk account and license key are required to use that service—this is not hidden or trial-locked code inside the plugin.

  • Multiple Avatars: Support for multiple digital human avatars
  • Real-time Communication: WebSocket and WebRTC powered conversations
  • Voice Interaction: Full duplex voice communication
  • Video Streaming: Real-time video of digital human responses
  • Responsive Design: Works on desktop and mobile devices
  • Customizable: Adjustable card dimensions and button text
  • Secure: License-based authentication
  • Elementor Integration: Custom widgets for Elementor page builder
  • Multiple Shortcodes: Avatar card, floating button, and list

Requirements

  • WordPress 5.0 or higher
  • PHP 7.2 or higher
  • Modern web browser with WebRTC support
  • HTTPS enabled (required for microphone access)
  • NavTalk account and license key

Privacy Policy

This plugin does not collect or store visitor personal data in the WordPress database. The site administrator stores the NavTalk license key in WordPress options. When visitors use the digital human, audio, video, and chat-related data are processed by NavTalk’s services as described below.

External services

This plugin connects the visitor’s browser and your WordPress site to NavTalk (operated by NavTalk / navtalk.ai) to load avatars and run real-time conversations.

  • HTTPS REST API (https://api.navtalk.ai): Used when the plugin or wp-admin requests avatar lists, avatar details, and connection tests. Requests send your license key in HTTP headers and may receive avatar metadata and media URLs.
  • WebSocket (wss://transfer.navtalk.ai): Used during an active session for real-time voice/video and messaging between the visitor’s browser and NavTalk.
  • Media delivery: Avatar images and preview videos are loaded from URLs returned by the API (for example from NavTalk CDN hosts such as https://cdn.navtalk.ai). The browser requests those assets directly.

Data sent to NavTalk includes at least your license key (from WordPress), session-related traffic over WebSocket (including voice/video where the user grants browser permissions), and any prompts or configuration you set in the plugin. What NavTalk logs or retains is governed by their policies.

Official policies (review before use):
* Terms of Service: https://navtalk.ai/policy/terms-of-service/
* Privacy Policy: https://navtalk.ai/policy/privacy-policy/

Third Party Services

Same as “External services” above: the plugin depends on NavTalk API, WebSocket, and related media hosts. See that section for endpoints, data flow, and policy links.

FAQ

What is NavTalk Digital Human?

It connects your site to NavTalk so you can embed AI-powered avatars that have real-time voice and video conversations with visitors.

Do I need a license key?

Yes, you need a NavTalk license key. Sign up at https://navtalk.ai to get your key.

What browsers are supported?

Chrome 80+, Firefox 75+, Safari 13+, Edge 80+, Opera 67+. WebRTC support is required.

Does this work with Elementor?

Yes! The plugin includes custom Elementor widgets for easy drag-and-drop integration.

Is HTTPS required?

Yes, HTTPS is required for microphone access (browser security requirement).

Can I use multiple avatars?

Yes, you can use as many avatars as your NavTalk plan allows.

How do I add an avatar to my page?

Use the shortcode: [navtalk_avatar avatarId=”your-avatar-id”] or use Elementor widgets.

How do I customize appearance?

Changelog

1.1.2

  • WordPress.org review: removed shortcode/admin inputs that accepted arbitrary button CSS or pasted icon markup.
  • Security: floating button background, color, size, position, modal dimensions, title tags, class names, and Elementor button appearance values now use stricter allowlists and sanitizers.
  • Security: Custom HTML blocks are no longer filtered through shortcode parsing; use the WordPress Shortcode block or normal shortcode-capable content areas instead.
  • Compatibility: existing navtalk_ options, shortcodes, CSS classes, JavaScript handles and AJAX actions are unchanged.

1.1.1

  • WordPress.org review: plugin display name, text domain, package root and main bootstrap file updated to navtalk-digital-human / navtalk-digital-human.php to match the approved slug.
  • Compatibility: existing navtalk_ options, shortcodes, CSS classes, JavaScript handles and AJAX actions are unchanged so current site settings and embedded shortcodes continue to work after update.

1.1.0

  • Packaging: plugin folder renamed to navtalk-digital-human to match the plugin slug and main bootstrap file, aligning with WordPress.org guidelines.
  • Encoding: source files normalized to UTF-8 (without BOM) and line endings standardized for better cross-platform compatibility and editor support.
  • Maintenance: documentation refreshed (README, install/shortcodes docs) and version metadata kept in sync across navtalk-digital-human.php, readme.txt and the installed-version option.
  • Compatibility: tested up to WordPress 7.0; verified shortcodes, admin settings, AJAX (test connection / refresh avatars), floating widget and Elementor widgets on WP 7.0. No breaking changes to existing shortcodes, settings or Elementor widgets.

1.0.7

  • Security: AJAX handlers (wp_ajax_navtalk_test_connection, wp_ajax_navtalk_refresh_avatars) now verify capability and nonce explicitly with current_user_can() + wp_verify_nonce() so Plugin Check can detect both checks statically.
  • Security: late escaping applied to all variable, option and generated output that was previously echoed via phpcs:ignore. render_overlay_layout() / render_bottom_layout() output is now passed through wp_kses() with a strict tag/attribute whitelist (NavTalk_Shortcode::allowed_avatar_card_html()); same fix applied to the Elementor avatar widget.
  • Security: remaining ternary echoes in admin/shortcode templates wrapped with esc_attr() / esc_html() (display:none toggles, status colors/badges, “Available/Unavailable” labels).
  • Refactor: the global floating-widget collapse-state script moved out of wp_add_inline_script into a registered file at public/js/navtalk-floating-collapse.js.

1.0.6

  • Plugin Check: limit readme tags to five; prefix globals in uninstall.php; icon preview handling hardened; drop redundant load_plugin_textdomain (WordPress.org-hosted translations load automatically since WP 4.6).
  • Note for scans: run Plugin Check with the plugin folder named navtalk-digital-human so the expected text domain matches the slug.

1.0.5

  • Release build for WordPress.org: Stable tag aligned with NAVTALK_VERSION; package root folder navtalk-digital-human with main file navtalk-digital-human.php (no functional change from 1.0.4).

1.0.4

  • WordPress.org review: plugin display name and text domain updated (NavTalk Digital Human / navtalk-digital-human); main bootstrap file renamed to navtalk-digital-human.php
  • Removed plugin settings field that stored custom CSS; use the theme Customizer “Additional CSS” (or Site Editor) instead
  • Elementor copy updated to clarify third-party NavTalk integration
  • Minor escaping and user-visible error label consistency

1.0.3

  • i18n: load text domain on plugins_loaded
  • Security: require valid nonces for admin AJAX (test connection, refresh avatars)
  • Uninstall: add uninstall.php to remove plugin options and _navtalk_show_floating post meta
  • Privacy: suggested policy text for Tools > Privacy (NavTalk data handling and policy links)
  • Readme: clarify SaaS model vs. trial-locked local code

1.0.2

  • Security and WordPress.org guidelines: removed admin-stored arbitrary JavaScript output; admin/settings scripts use wp_add_inline_script
  • Floating widget collapse-state script uses wp_add_inline_script instead of raw tags in the footer
  • Readme: expanded External services disclosure with data flow and Terms/Privacy links
  • Settings: floating position option sanitized against an allowed list (bottom/top corners)

  • Initial release
  • Basic shortcode functionality ([navtalk_avatar])
  • Floating button shortcode ([navtalk_floating])
