Guide for Magento 2 AI Product Recommendation

Magento 2 Product Recommendations extension is an additional feature for the Magento 2 e-commerce platform. 

It allows the store admins to enable AI-based product recommendations on their Magento 2 store.

Magento 2 AI product recommendation utilizes artificial intelligence to suggest products to the customers in the Adobe Commerce store.

The AI algorithm analyzes the products viewed by the customer and provides product suggestions using the embedding technique.

It matches the products’ names, SKUs, super attributes, searchable attributes, and filterable attributes to suggest similar products in the Magento store.

Check the overview of Magento 2 AI Product Recommendations below –

You can also check our Magento 2 AI Image Search Extension where a customer can search for products based on images using AI technology.

For added functionality, consider exploring the Magento 2 Image Background Removal extension to remove image backgrounds.

Also, you can check the Adobe Commerce AI reporting dashboard that give you an upper hand on enhanced data analysis within the Magento 2 store.

• The admin can set the number of suggested products to display, ranging from 1 to 10.
• Increase average order value with smart bundling.
• Automatically generates product recommendations for customers.
• Matches products based on names, SKUs, super attributes, searchable attributes and filterable attributes.
• Uses embedding Technique to identify and recommend products through AI.

Language Translation

For translating the module language, navigate through the app/code/Webkul/AIProductRecommendation/i18n and edit the en_US.csv file.

Thereafter, rename the CSV as “en_SA.csv” and translate all right side content after the comma in the Arabic language. After editing the CSV, save it.

Now, upload it to the path app/code/Webkul/AIProductRecommendation/i18n where the installation of Magento 2 is on the server.

Magento 2 Product Recommendations will be translated into the Arabic Language. It supports both RTL and LTR languages.

The user can edit the CSV like the image below.

Initial Configuration Settings

After the successful installation of the module, the admin will navigate to Stores > Configuration > AI Product Recommendation Configuration.

After enabling the module, the admin can access the initial configuration by navigating AI Product Recommendation Manager> System Configuration.

General Settings:

1. Enabled: The admin can enable or disable the extension functionality in their Magento 2 store by choosing Yes or No.

2. LLM Engine: The LLM Engine determines which AI service is used to run the platform’s intelligent functionality. When you click on the LLM Engine option, two dropdown choices are available:

3. LLM Bridge Provider: The LLM Bridge Provider defines which external AI service is connected to the platform to process and generate intelligent outputs.

Available LLM Providers: OpenAI, OpenRouter, Gemini, Voyage, Mistral, and ONNX.

4. LLM Embedding Model: In this section, the admin can choose the LLM embedding model to be used for processing and understanding data.

5. LLM Image Bridge Provider: The LLM Image Bridge Provider section allows the admin to select the LLM provider used for generating image embeddings.

6. LLM Image Embedding Model: Select image embedding model for selected LLM image bridge provider.

7. LLM Image Embedding API Key: Enter the API key for the selected image embedding provider. You can find the API key here: API Key

8. API Key: Fill the API key. For LLM, use OpenAI / Gemini / Voyage API key as per the selected bridge.

After entering the API key, the admin can click the Validate button to verify the API key and ensure the AI configuration is set up correctly.

9. Select Attributes to create Embeddings: Admin selects the product’s attributes to create embeddings. Embeddings will be created with selected attribute values.

OpenSearch Similarity Metric: Similarity function used for vector search (cosinesimil recommended for OpenSearch k-NN).

Text Embedding Dimension: Text embedding dimension used for vector index creation across all supported vector databases.

Image Embedding Dimension: Image embedding dimension used for vector index creation across all supported vector databases.

Validate Connection: Click this button to validate the configuration and ensure the connection with the selected vector database is working correctly.

Below Image Shows How to Train Data/Generate Embeddings

The admin can create a new recommendation by navigating to AI Product Recommendation Manager, then going to the Recommendations section and clicking on Add New Recommendation.

Storefront – Workflow AI Product Recommendation

After the successful configuration of the module, on the product page, it will generate the AI Recommended section for products suggested by AI.

Adjusting the distance value to 1 and the show products value to 5 in the backend will more accurately display five products recommended by AI.

let us take another product’s example: changing the distance value to 4 and the show products value to 7 in the backend.

Similarly, the admin can choose the number of products to be recommended by the AI and the accuracy of the suggestion as per his choice.
