Description
The easiest way to add an AI chatbot to WordPress and WooCommerce
Do you want to add an AI assistant, customer support bot, or automated live chat to your WooCommerce store or WordPress site?
Flexible Chat is a free WordPress AI chatbot plugin that connects a ready-made chat widget directly to your n8n workflows – bring any AI agent or automation you’ve already built in n8n straight to your frontend, no code required.
If you’re searching for an n8n chat widget for WordPress, a live chat for WooCommerce, or a no-code AI chatbot plugin, Flexible Chat is built exactly for that.
With Flexible Chat you can:
-
Connect any n8n HTTP webhook to a polished frontend chat interface.
-
Engage visitors with real-time streaming responses, just like ChatGPT.
-
Route conversations by topic before the chat starts.
-
Fully customize colors, texts, and behavior – no coding required.
⚠️ Requires your own n8n instance
Flexible Chat is a frontend only – it has no AI logic of its own. You need your own n8n instance (self-hosted or n8n Cloud, a separate service not affiliated with WP Desk) with at least one workflow exposing an HTTP Webhook. Build a basic workflow (Webhook AI node Respond) in n8n, copy its webhook URL, and paste it into the plugin settings. Without an n8n workflow, the plugin has nothing to connect to.
Key features
-
Seamless n8n webhook integration – connect via a simple webhook URL.

FAQ
-
Do I need an n8n account to use this plugin?
-
Yes, and it’s required, not optional. Flexible Chat is a chat frontend for n8n – it has no built-in AI. You need your own n8n instance (self-hosted or Cloud) with a workflow exposing an HTTP Webhook. The plugin sends messages to that webhook and displays the response. If you’ve never used n8n, you’ll need to build a basic workflow there first.
-
Does it support real-time streaming like ChatGPT?
-
Yes, as long as your n8n workflow returns the response in a compatible streaming format. Visitors see the AI typing in real time, reducing perceived waiting time.
-
Can I change the chat widget colors to match my brand?
-
Yes. Change primary/background/text colors and border radius in the settings, or override styling with CSS variables or custom classes for full control.
-
Can I pass user data (like email or user ID) to my n8n workflow?
-
Yes. Send custom metadata – user ID, email, page URL, subscription plan – with every message via a custom JSON payload, so your n8n workflow can personalize responses or integrate with your CRM.
-
Can I ask the visitor what they want to talk about first?
-
Yes. Configure suggested topics (e.g. “Sales”, “Support”); the visitor’s choice is sent to n8n to route the chat to the right agent or logic branch.
-
Do I need coding skills to set this up?
-
No coding is required for the plugin itself – just paste the webhook URL and configure options in the admin panel. You will need to build at least a basic n8n workflow first, which uses n8n’s visual editor rather than code, but does require some familiarity with the tool.
-
What’s the difference between Flexible Chat and Flexible Chat PRO?
-
The free version covers a single n8n webhook with full visual customization, streaming, topic routing, and file uploads. Flexible Chat PRO adds support for multiple AI agents/workflows, advanced visitor targeting, and priority support.
-
Can I use Flexible Chat as a WooCommerce live chat widget?
-
Yes. It works on any WooCommerce page – product, cart, checkout, account – the same way as on regular WordPress content. Connect it to an n8n workflow reading order or product data for a WooCommerce live chat backed by your own automation.
-
Where do I report security bugs found in this plugin?
-
You can report security bugs through the Patchstack Vulnerability Disclosure Program. The Patchstack team help validate, triage and handle any security vulnerabilities. Report a security vulnerability.
