The Knowband OpenCart AI Review Generator Extension<\/a> changes that. It connects your OpenCart store to an AI provider of your choice- OpenAI (ChatGPT), Anthropic (Claude), or Google (Gemini)- and generates product-specific reviews directly from your admin panel. You set the rules. The extension handles everything else.<\/span><\/p>\n Each generated review comes with a star rating, a title, a review body written in your chosen tone, and a guest reviewer profile with a randomised name. All reviews are published through OpenCart’s native review system and appear on product pages exactly the way a real customer review would.<\/span><\/p>\n This guide walks through every setting, tab, and option so you can get the OpenCart AI review generator configured and running from day one.<\/span><\/p>\n <\/p>\n Step 1:<\/b> Download the extension ZIP file from your Knowband account.<\/span><\/p>\n Step 2:<\/b> Log in to your OpenCart admin panel and go to Extensions, then Extension Installer.<\/span><\/p>\n Step 3:<\/b> Upload the ocmod.zip file using the file upload option. OpenCart will handle unpacking automatically.<\/span><\/p>\n Step 4:<\/b> Log in with FTP, copy all the folders from the <\/span>Upload folders<\/b> to your store, and select the Modules category. Locate the AI Review Generator in the list and click Install.<\/span><\/p>\n Step 5:<\/b> After installation, click Edit to open the configuration panel.<\/span><\/p>\n Common Installation Problems<\/b><\/p>\n Upload fails:<\/b> Your server’s file upload limit is likely too low. Ask your hosting provider to raise <\/span>upload_max_filesize<\/span> and <\/span>post_max_size<\/span> to at least 32 MB.<\/span><\/p>\n Extension not appearing in the list:<\/b> Clear your OpenCart cache by going to Dashboard and clicking the blue cog icon, then Refresh. Run the search again.<\/span><\/p>\n After installing the extension, the Opencart AI Review Generator integrates three main sections to your opencart admin panel:<\/span><\/p>\n The General Settings tab holds your global configuration. Changes here affect how the entire extension operates.<\/span><\/p>\n The main on\/off switch. When enabled, the extension is active and ready to generate. When disabled, all generation stops, but every rule, review, and history entry stays saved exactly as it was.<\/span><\/p>\n Choose which AI service you want to use for generating reviews:<\/span><\/p>\n Only one provider runs at a time. Switching providers does not affect any rules you have already created or reviews that have already been generated.<\/span><\/p>\n Paste your API key for the selected provider here. Without a valid key, the extension cannot connect to the AI service, and generation will not run.<\/span><\/p>\n Getting your API key:<\/b><\/p>\n Use the <\/span>Test Connection<\/b> button to confirm the key is working before saving.<\/span><\/p>\n Select the specific AI model to use. Admins can see the available options depending on your requirements. These AI models include ChatGPT, Claude and Gemini models.<\/span><\/p>\n These AI Models in OpenCart product review generation through AI<\/a> include these models:<\/span><\/p>\n OpenAI ChatGPT models:<\/b> GPT-5.5, GPT-5.4, GPT-5.4 mini, GPT-5.4 nano, GPT-5, GPT-4.1, GPT-4.1 mini, GPT-4.1 nano, o3, o3-mini, o4-mini, GPT-4o, GPT-4o mini, GPT-4 Turbo, GPT-4, GPT-3.5 Turbo<\/span><\/p>\n Anthropic Claude models:<\/b> Claude Opus 4.7, Claude Sonnet 4.6, Claude Opus 4.6, Claude Opus 4.5, Claude Sonnet 4.5, Claude Haiku 4.5, Claude Opus 4.1, Claude Sonnet 4, Claude Opus 4<\/span><\/p>\n Google Gemini models:<\/b> Gemini 3.5 Flash, Gemini 3 Flash Preview, Gemini 3.1 Flash-Lite, Gemini 2.5 Flash-Lite, Gemini Flash Latest, Gemini Flash-Lite Latest<\/span><\/p>\n Store admins can set the maximum amount of text the AI can write per review request in the OpenCart customer review generator. The range is 1 to 16,384, with a default of 4,000.<\/span><\/p>\n Higher values give the AI room to write longer, more detailed content but increase the API cost for each run. Additionally, it is recommended to keep lower values for reviews shorter and reduce cost. Admins can set this in line with the Max Words per Review value you configure in each rule.<\/span><\/p>\n Merchants can also handle the creativity of the Opencart SEO Powered Reviews Generator by controlling the temperature values scale, which runs from 0.0 to 1.0. For ChatGPT\u2018s GPT 5.5, temperature is not supported in the module.<\/span><\/p>\n At 0.0, responses are predictable and stay close to a fixed pattern ,\u00a0 good if you need every review to hold a consistent tone. Closer to 1.0, the output becomes more varied and less uniform. For reviews that read naturally, a value between 0.5 and 0.7 works well for most stores.<\/span><\/p>\n When set to Yes, the Knowband OpenCart AI-generated customer reviews check each product before running the generation. If a product already has reviews, it is skipped entirely. This prevents the same product from accumulating repeated batches and avoids wasting API tokens on products that do not need new content.<\/span><\/p>\n The General Settings tab provides a token-secured URL for automated review generation. Copy this URL and add it to your server as a cron job.<\/span><\/p>\n Running it every 15 minutes is the recommended frequency. Only requests carrying the correct token will trigger generation; the URL does nothing without it.<\/span><\/p>\n Click <\/span>Save<\/b> before leaving this tab.<\/span><\/p>\n Review Rules are where you control exactly how the OpenCart automated review generation process runs. Each rule targets a specific group of products or categories and defines all the parameters, publishing timing, generation limits, tone, language, and rating breakdown.<\/span><\/p>\n The Review Rules list shows every rule with its ID, name, publish mode, content type, daily limit, active status, and assigned store. Hit <\/span>Generate Now<\/b> on any row to run that rule immediately. Click <\/span>Edit<\/b> to change its settings.<\/span><\/p>\n Store admins can <\/span>add a rule<\/b> to generate the reviews based on the configurations added in OpenCart automated product reviews.<\/span><\/p>\n Store:<\/b> Select which store this rule applies to if you run a multi-store setup in Opencart<\/span><\/p>\n Enable Rule:<\/b> Toggle on to make the rule active. Inactive rules are saved but will not run on CRON or when Generate Now is clicked.<\/span><\/p>\n Publish Mode:<\/b><\/p>\n Random Delay (days):<\/b> Appears when Scheduled mode is selected. Set a minimum and maximum day range. Each generated review is published at a random point within that window.<\/span><\/p>\n Max per Cron:<\/b> The maximum number of reviews this rule can generate in a single CRON run.<\/span><\/p>\n Max per Day:<\/b> The total number of reviews this rule can generate across all CRON runs in one calendar day.<\/span><\/p>\n Max per Product per Day:<\/b> Handles how many reviews a single product can receive from this rule in one day using Knowband eCommerce Review Generations. This keeps any one product from picking up an unnatural volume in a short period.<\/span><\/p>\n Max Words per Review:<\/b> The word limit for each generated review body. Use 150 for standard reviews. Drop to 50 or below for short-form content. Raise it for long, detailed reviews.<\/span><\/p>\n Languages:<\/b> Tick each language you want reviews generated in. Selecting both English and French means every review is generated in both. Only languages installed in your OpenCart store appear in this list.<\/span><\/p>\n Content Type:<\/b> Choose whether the rule targets specific Products or entire Categories. Selecting Products lets you search and add individual items. Selecting Categories applies the rule to every product within that category.<\/span><\/p>\n Tone:<\/b> Set the voice for generated reviews.<\/span><\/p>\n Generate using:<\/b> Toggle which product data points the AI uses when writing each review. At least one must be active.<\/span><\/p>\n Enabling the description gives the AI more context for specific, accurate content. Enabling price means reviews may reference value for money. Disabling a data point means the AI will not factor it in.<\/span><\/p>\n Rating Distribution (%):<\/b> Store admins can set the percentage split across 1 to 5 star ratings. The total must equal exactly 100. For example: 5 stars at 50%, 4 stars at 30%, 3 stars at 10%, 2 stars at 5%, 1 star at 5%. The extension follows this distribution when assigning ratings to each generated review, so the overall profile on a product page looks realistic rather than uniformly perfect.<\/span><\/p>\n Rule Name:<\/b> A required field. Give each rule a name that makes its purpose clear ,\u00a0 for example, Winter Range English or Homepage Categories Casual.<\/span><\/p>\n Custom Prompt:<\/b> An optional field in given in the rule review configurations that replaces the default generation instruction for this rule. Write a plain instruction and use the supported variables to pull product data into the prompt.<\/span><\/p>\n Supported variables are: <\/span>{product_name}<\/span>, <\/span>{product_description}<\/span>, <\/span>{price}<\/span>, <\/span>{category}<\/span>, <\/span>{shop_name}<\/span>, <\/span>{tone}<\/span>, <\/span>{max_words}<\/span><\/p>\n Click <\/span>Save<\/b> to create the rule. It will appear in the Review Rules list straight away.<\/span><\/p>\n Click <\/span>Edit<\/b> on any rule row to reopen the form and change any setting. Use the dropdown arrow beside Edit and select <\/span>Delete<\/b> to remove a rule permanently. Deleting a rule does not remove reviews that were already generated under it in the reviews tab in the OpenCart review creation Plugin<\/a>.<\/span><\/p>\n The Bulk Actions dropdown at the bottom of the rules list lets you apply actions to multiple selected rules at once.<\/span><\/p>\n The Reviews tab shows every review the extension has generated. This is where you manage, approve, or remove reviews before or after they reach the product page.<\/span><\/p>\n2.0 Installation Steps<\/b><\/h2>\n
