# How to add AI customer service to WordPress - URL: https://www.chaterimo.com/en/blog/how-to-integrate-ai-customer-service-to-your-wordpress/ - Language: en - Type: Guide - Author: David Langr - Published: 2024-05-03 - Updated: 2026-10-19 > Train a Chaterimo AI chatbot on your WordPress site, then add its chat widget with one line of code in the footer, for example with the WPCode plugin. ## Key findings - Chaterimo adds an AI chatbot to a WordPress site with one line of code that loads the chat widget; Chaterimo has no WordPress plugin of its own. - The chatbot answers from its knowledge base: pages imported from your sitemap, your texts and files and, for WooCommerce, a product feed in Google Shopping format. - You paste the line once, in the footer of every page, for example with the free WPCode plugin under Code Snippets → Header & Footer. - The chat widget runs only on the domains listed under Allowed domains in Chaterimo, so list every domain where the site runs. To add AI customer service to a WordPress site, train a Chaterimo chatbot on your content and paste one line of code from Chaterimo into the footer of your site. The line loads the chat widget on every page; the free WPCode plugin is the simplest way to add it without editing the theme. This guide is for owners of WordPress sites and WooCommerce stores who want an AI chatbot that answers customers from their own pages and products. ## Steps ### 1. Create a Chaterimo account [Sign up for Chaterimo](https://www.chaterimo.com/en/signup/) and fill in **Email**, **Password**, **Confirm Password**, **Name of organisation** and **Website domain**. In **Website domain**, enter the domain of your WordPress site, for example `example.com`: the chat widget will run on that domain. Chaterimo sends a token to your e-mail address. Enter it on the **Account Activation** page and select **Submit**. The new account starts with a 7-day trial with all features. The plans after the trial are on the [pricing page](https://www.chaterimo.com/en/pricing/). ### 2. Add your content to the knowledge base The chatbot answers only from what you give it. In Chaterimo, open **Knowledge Base → Get Data** and choose the sources: Website Scraping : Under **Scrape your sitemap**, enter the address of your sitemap and select **Load sitemap**. WordPress publishes one at `/wp-sitemap.xml`; an SEO plugin may replace it with its own sitemap.[^1] Choose the sections to import, for example pages and posts, and select **Import selected pages**. One import takes at most 2,500 URLs. Turn on **Scrape this sitemap daily (automatically includes new URLs)** to keep the chatbot current. Text Input : Paste your shipping, returns, payment and contact rules or your FAQ. File Upload : Upload price lists, manuals or terms: PDF, Word, PowerPoint, Excel, CSV, TXT or images, up to 10 MB each. XML Product Feed : For a WooCommerce store, import the products from a product feed in Google Shopping format. WooCommerce does not publish such a feed by itself; a product feed plugin does. Turn on **Download this feed again every day and retrain** so prices and stock stay current. Then open **Knowledge Base** and select **Train chatbot**. ### 3. Test the chatbot Open **Test Chatbot** and ask the questions your customers ask most often. If an answer is wrong or missing, add the information in step 2 and train again. To choose a different AI model, see **AI model type** in **Chat Settings & Embed**; our [blind test of AI models in customer support](https://www.chaterimo.com/en/blog/best-ai-for-customer-support/) compares them. ### 4. Check the allowed domains and copy the code Open **Chat Settings & Embed**. Under **Appearance chatbot settings**, **Allowed domains** already holds the domain you entered at sign-up. Add every other domain where the site runs, for example a staging copy, and select **Save changes**. Subdomains of a listed domain are allowed too, and `www.` makes no difference. Then expand **Website installation** and copy the line under **Recommended: organisation language loader** with the copy button next to it. The line looks like this: ```html ``` The line stays the same when you later change the chatbot or its languages, so you paste it only once. ### 5. Install the WPCode plugin In the WordPress admin, open **Plugins → Add Plugin** (**Add New Plugin** or **Add New** in WordPress versions before 6.8), search for “WPCode”, select **Install Now** and then **Activate**. The plugin is called “WPCode – Insert Headers and Footers + Custom Code Snippets”.[^2] On WordPress.com, installing plugins needs a paid plan.[^3] ### 6. Paste the code into the footer Open **Code Snippets → Header & Footer**, paste the line from step 4 into **Footer** and select **Save Changes**. WPCode puts footer code just before the closing `` tag of every page, which is where Chaterimo recommends it.[^4] Paste the line only once. If you do not want a plugin, a developer can add the same line to the site-wide layout of your theme, just before ``. ## How to check it works 1. Open your site in a private browser window. The chat bubble is in the corner of the page. 2. Ask a question about your products or services. The answer should come from the content you imported. 3. Open **Chat History** in Chaterimo. Your test conversation is there. 4. Open the page source and search for `chat-widget`. The line should be there exactly once. ## Troubleshooting The chat bubble does not appear : Check that WPCode is active and the line is saved in **Footer**. If you use a caching plugin, clear its cache. Plugins that delay or combine JavaScript can hold the line back; exclude it from that optimisation. Visitors see “This chat isn't available on this website.” : The domain of the page is not in **Allowed domains**. Add it in **Chat Settings & Embed** and select **Save changes**. “The organisation loader is not ready yet. Import and train data, then refresh the loader.” : Chaterimo prepares the line once the knowledge base has data. Import your content (step 2), select **Train chatbot** under **Knowledge Base**, then open **Chat Settings & Embed** again. “The sitemap could not be loaded. Check the address and try again.” : Open the sitemap address in your browser. If it does not load there, check which sitemap your SEO plugin publishes, or import the pages one by one under **Scrape a single link**. The line is on the page twice : It was added in two places, for example in WPCode and in the theme. Keep one copy, as Chaterimo asks in **Website installation**. ## Next step Read [how to choose an LLM for customer support](https://www.chaterimo.com/en/blog/how-to-choose-llm-for-customer-support/) and test two or three models on your customers' questions. If you are setting up Chaterimo for the first time, start with [your first chatbot in 4 steps](https://www.chaterimo.com/en/blog/create-chatgpt-chatbot-chaterimo-4-steps/). If your plan uses your own API key, the [OpenAI API key guide](https://www.chaterimo.com/en/blog/how-to-openai-api-account/) shows how to get one. **Is there a Chaterimo plugin for WordPress?** No. Chaterimo works on WordPress through one line of code that loads the chat widget. A general plugin such as WPCode puts it into the footer of every page. **Does Chaterimo work with WooCommerce?** Yes. Import your products from a product feed in Google Shopping format under **XML Product Feed**, and your pages and policies from your sitemap. The chatbot then recommends products from the feed. **Where should the code go, in the header or the footer?** In the footer, once, so it loads on every page. Chaterimo recommends placing it just before the closing `` tag. **Do I need to change the code when I change the chatbot?** No. The line stays the same when you change the chatbot's settings, the primary chatbot or the language routing, so you paste it only once.
