Description

VoxAI – AI Audio & Summary for Posts transforms your content into a richer, more accessible experience. With a single click, your posts get a professional audio narration and an AI-written summary — no recording equipment, no manual editing.

Readers stay longer. Bounce rates drop. Your content becomes accessible to audiences who prefer to listen.

✨ Key Features

AI Summary Generator
Uses OpenAI GPT-4o Mini to read your article and write a concise, accurate summary. The summary appears in a collapsible panel inside your post — clean, discreet, and on-brand.

Text-to-Speech Audio Player
Converts your full article into natural-sounding audio using OpenAI’s TTS engine. Six high-quality voices available (Alloy, Echo, Fable, Onyx, Nova, Shimmer). The MP3 is saved to your server — no recurring API call for playback.

Reading Time Estimator
Automatically calculates and displays the estimated reading time for every post. Configurable and translatable.

Smart Positioning
Choose to inject the AI Reader widget before the content, after the content, or disable injection entirely and use the shortcodes manually.

Shortcodes for Full Control
– [voxaiau_summary] — Displays the AI Summary panel.
– [voxaiau_tts] — Displays the AI Audio player.

📝 Works Where the Official AI Plugin Doesn’t

The official WordPress AI plugin is Gutenberg-only. Every feature it offers — title generation, summarization, excerpt, alt text — lives inside the block editor sidebar. Activate the Classic Editor plugin and all of it disappears.

VoxAI is different. It was built to work in both environments from day one:

Gutenberg — Full sidebar panel with real-time generation status, voice selector, and cost estimator.
Classic Editor — Dedicated metabox with exactly the same features: generate summary, generate audio, voice selector, per-post cost display.

If your site runs the Classic Editor — or if you manage a client site that does — VoxAI is the only AI audio and summary plugin that works out of the box, no editor swap required.

🔗 WordPress 7.0 & Official AI Plugin Compatible

VoxAI integrates natively with the WordPress 7.0 AI infrastructure:

WP AI Client support — When the site has an AI Connector configured (Settings Connectors), VoxAI uses it for summary generation without requiring a separate API key. Falls back to your OpenAI key if no connector is configured.
Abilities API — Registers voxai/generate-audio and voxai/generate-summary as discoverable AI Abilities. They appear in the Abilities Explorer and can be triggered by AI agents or automation workflows.
Complements, not competes — The official AI plugin handles text features (title, excerpt, classification). VoxAI adds the one thing it doesn’t have: professional audio narration.
Editor-agnostic — Unlike the official AI plugin, VoxAI works identically with Gutenberg and with the Classic Editor plugin active.

🔧 Zero configuration required to start

Paste your OpenAI API key in Settings AI Audio & Summary, choose which post types to activate it on, and you’re done. The widget renders automatically.

FAQ

Do I need an OpenAI account?

Yes. This plugin uses the OpenAI API to generate summaries and audio. You need an OpenAI account with a valid API key and available credits.

Does it send my content to OpenAI automatically?

No — content is only sent to OpenAI when requested via the “Generate Summary” or “Generate Audio” buttons inside the post editor, or when a user views a post without a cached summary.

How much does it cost to use?

The plugin itself is free. You pay OpenAI directly for API usage. A typical article summary (GPT-4o Mini) costs less than $0.001 USD. A full audio narration (1000 words, tts-1 model) costs approximately $0.02–$0.04 USD.

Is the audio file stored on my server?

Yes. Once generated, the MP3 file is saved securely on your own WordPress server inside the uploads directory. Playback never calls the OpenAI API again.

Does it work with Gutenberg and Classic Editor?

Yes — and this is a key advantage over the official WordPress AI plugin. VoxAI has full support for both the Classic Editor (dedicated metabox) and the Gutenberg block editor (sidebar panels with real-time feedback). All features — summary generation, audio generation, voice selector, cost estimator — are available in both editors.

The official WordPress AI plugin (wordpress.org/plugins/ai) is Gutenberg-only. If you or your clients use the Classic Editor plugin, the official AI plugin offers no AI features at all. VoxAI fills that gap completely.

I really liked your WordPress plugin and found it extremely useful, especially for news blogs and content websites. The voice quality is surprisingly good — very natural and pleasant to listen to. It creates a much better experience for readers who prefer audio content. Great work on the overall quality and usability of the plugin!

I recently started using VoxAI to convert my blog posts into audio, and it has been an absolute game-changer. The AI voices sound incredibly natural and not robotic at all. It was super easy to set up and it seamlessly generates high-quality audio versions of my articles. This is a fantastic way to improve accessibility on my site and keep my audience engaged, especially for readers who prefer listening on the go. If you want to offer an audio option to your audience without spending hours recording it yourself, this is the perfect solution. Excellent plugin!

Changelog

1.1.0 — May 2026

New: WordPress 7.0 AI integration — VoxAI now uses the native WP AI Client (provider-agnostic) for summary generation when a connector is configured in Settings Connectors.
New: Abilities API — registers voxai/generate-audio and voxai/generate-summary as discoverable abilities visible in the Abilities Explorer.
New: Summary Formatting — Added a setting to choose the output format of the summary (Continuous Paragraph or Bulleted List).
Improvement: Robust Fallback System (“Cardápio”) — If WP AI, Claude, or Gemini fails (e.g. missing keys or “No models found”), the system gracefully and silently falls back to the native OpenAI key.
Improvement: When selecting Bulleted List formatting, the AI now strictly enforces proper Unicode bullet characters (•).
Improvement: Detected summaries already generated by the official WordPress AI plugin are reused, avoiding redundant API calls.
Fix: Resolved a fatal error that caused the summary generation button to fail due to a missing DocBlock terminator.
Fix: Fixed a PHP Notice in WordPress 7.0 by correctly hooking wp_register_ability to wp_abilities_api_init instead of init.

1.0.8

Fix: Resolved a timezone issue causing the “Top Posts This Month” chart to fail filtering plays correctly on some servers.
Fix: Improved frontend listener tracking reliability by migrating from JSON blobs to FormData to prevent adblockers and restrictive browsers from dropping the telemetry data.

1.0.7

Fix: Added cache buster and delay to bypass CDN/cache 412 errors when loading newly generated audio.
Fix: Statistics panel now correctly filters “Without Audio” count to only include enabled post types.

1.0.6

Fix: Resolved audio player source error.
Fix: Corrected issues with the statistics page display.

1.0.5

Improvement: Statistics panel UI restructure. The global chart now displays a Top Posts ranking instead of a daily plays chart for better insights.
Improvement: Telemetry tracking split. The Free plugin now only processes basic metrics (plays and listeners), keeping the database leaner and faster. Advanced retention metrics (listen time and completion rate) are strictly handled by the Pro add-on.
Fix: Removed complex SQL aggregate functions from the Free tracking table.

1.0.4 — May 2026

Improvement: Progress messages during audio generation (Prepare / Process Chunks / Finalize) are now fully translatable in both Gutenberg and Classic Editor.
Fix: Progress text was previously hardcoded in Portuguese; now uses the WordPress i18n system with pt_BR fully translated.

1.0.3 — May 2026

New: GitHub Updater — the WordPress dashboard now shows update notifications automatically when a new version is released.
Fix: Cost calculator now works correctly with Classic Editor loaded without the official plugin (robust TinyMCE binding).

1.0.2 — May 2026

Bug fix: accordion now opens correctly on posts without generated audio.
Improvement: accordion and audio player are only rendered when their content exists.
Removed: voxai_faq shortcode and FAQ block (placeholder feature removed).
