Next3 AI Assistant

The Next3 AI Assistant Addon combines AI-powered media optimization with secure Model Context Protocol (MCP) integration.

It can automatically optimize images, generate media metadata, convert images to modern formats, remove backgrounds, and connect Next3 Offload with ChatGPT, Claude, Codex, and other MCP-compatible applications.

With this addon, you can:

  • Optimize images before they enter the WordPress Media Library
  • Generate alt text, captions, and descriptions automatically
  • Convert images to WebP or AVIF
  • Detect duplicate uploads
  • Enable lazy loading
  • Remove image backgrounds
  • Find and manage WordPress media through an AI assistant
  • Offload, restore, optimize, and clean media using natural-language prompts
  • Protect destructive operations with confirmation

Requirements

Before configuring the addon, make sure you have:

  • Next3 Offload installed and activated
  • Next3 AI Assistant installed and activated
  • A cloud storage provider configured in Next3 Offload
  • A valid API key from a supported AI provider
  • Administrator access to WordPress

For MCP connections, you also need:

  • A publicly accessible HTTPS WordPress website
  • A non-Plain WordPress permalink structure
  • An MCP-compatible application such as ChatGPT or Claude
  • The MCP endpoint and OAuth registration enabled

ChatGPT and Claude cannot connect directly to a private localhost website or a plain HTTP URL. Use your live HTTPS website or a trusted HTTPS tunnel for testing.

Accessing Next3 AI Settings

To access the Next3 AI Assistant settings:

  1. Sign in to your WordPress dashboard.
  2. Open Next3 Offload.
  3. Select AI Settings from the left sidebar.

The AI Settings area contains three main sections:

  • API Key
  • Settings
  • MCP Integration

Connecting an AI Provider

Next3 AI Assistant supports the following AI providers:

  • OpenAI
  • Gemini
  • DeepSeek
  • Kimi

To connect an AI provider:

  1. Open Next3 Offload → AI Settings → API Key.
  2. Select your preferred provider.
  3. Enter the provider API key.
  4. Select the AI model you want to use.
  5. Click Save Settings.

The available models depend on the selected provider. Choose a higher-quality model for more detailed image analysis or a faster model for lower processing cost.

Keep your AI provider API key private. Never include it in screenshots, support messages, or MCP prompts.

Configuring AI Image Optimization

Open Next3 Offload → AI Settings → Settings to configure image-processing features.

Image Optimization

Enable Image Optimization to process images before they are added to the WordPress Media Library.

When enabled, Next3 AI Assistant can optimize newly uploaded images as part of the upload workflow.

User Prompt for Image Optimization

Use the custom prompt field to provide instructions for image processing and metadata generation.

For example:

Create clear, natural, SEO-friendly metadata for this image. Describe only the visible content and avoid keyword stuffing.

A custom prompt is optional. Leave it empty to use the default Next3 AI instructions.

Automatic Alt Text, Captions, and Descriptions

Enable Generate Alt Tags, Caption and Description Automatically to let the selected AI provider analyze uploaded images.

The addon can generate:

  • Image title
  • Alt text
  • Caption
  • Description

Generated alt text is saved to the standard WordPress image alt-text field. Captions and descriptions are saved to the corresponding attachment fields.

Always review generated metadata when accuracy is especially important.

Compression Type

Select the format that Next3 AI Assistant should use during optimization:

  • None — Keep the original image format
  • WebP — Convert the image to WebP
  • AVIF — Convert the image to AVIF

WebP offers broad browser compatibility and good compression. AVIF can provide smaller files, although processing and browser support may vary.

Lazy Loading

Enable Lazy Loading to delay loading images until they are close to becoming visible on the visitor’s screen.

This can improve initial page-loading performance, particularly on pages containing many images.

Background Removal

Enable Background Removal to remove image backgrounds during the upload process.

Background removal requires a separate API key from remove.bg.

To configure it:

  1. Enable Background Removal.
  2. Obtain an API key from https://www.remove.bg/api.
  3. Enter the key in API Key for Background Removal.
  4. Save the settings.

Background removal is optional and may use credits from your remove.bg account.

How Image Processing Works

After the AI settings are configured, the upload workflow works as follows:

  1. You upload an image to WordPress.
  2. Next3 checks for an existing duplicate when duplicate detection is enabled.
  3. The selected AI provider analyzes the image when automatic metadata is enabled.
  4. Alt text, captions, and descriptions are generated.
  5. Background removal runs when enabled.
  6. The image is optimized or converted to the selected format.
  7. WordPress creates the Media Library attachment.
  8. Next3 Offload processes the image according to your cloud-storage settings.

If one optional AI operation fails, the addon may continue the upload without that operation instead of blocking the entire upload.
