Choose a WordPress AI chatbot by how it reaches your site. Plugins run inside WordPress and usually need your own AI provider key. Hosted bots install a small plugin but keep the AI and chat data on their platform. Bot builders go on with a pasted snippet. That route decides who holds the AI account and where conversations are stored.
The decision on this page isn't which chatbot sounds cleverest. It's how the bot gets onto your WordPress site, because that one choice settles who holds the AI account, where the conversations are kept and what breaks when you change theme.
Ten tools follow in no particular order, grouped by that route first.
Three routes onto a WordPress site
Not every WordPress AI chatbot is a plugin you run yourself. There are three routes, and each one moves the work and the data somewhere different.
Plugins that run inside WordPress
AI Engine, WPBot, Kognetiks Chatbot and AI Puffer install like any plugin, alongside Ays ChatGPT Assistant. The bot runs from your site, but the thinking still happens at an AI provider. Kognetiks says its plugin needs an API key from a provider to work, so you hold that account and its settings.
Hosted bots with their own WordPress plugin
CustomGPT.ai and ChatBot.com run the bot on their own platforms and give you a WordPress plugin to place it. Jotform AI Agents belongs here too, listing a WordPress version among its agents. The AI and the chat history live with the vendor.
Bot builders you embed with a snippet
Botpress and Landbot are builders you use outside WordPress. You add the finished bot by pasting an embed code; one builder's docs have you do it through a separate code-snippet plugin rather than one of its own. Change themes carelessly and the snippet can vanish with them.
All ten chatbots, in no particular order
AI Engine
Best for: Site owners wanting a visitor chatbot, AI help in the editor and MCP access for AI agents, with the vendor saying a bot can go live without code.
AI Puffer
Best for: Letting AI assistants help manage the site through an MCP server, alongside a chatbot that runs on its cloud or your own provider keys.
Ays ChatGPT Assistant
Best for: Connecting ChatGPT to your site for a visitor chatbot and content tasks, with a pro version and demos offered on its page.
Botpress
Best for: Teams building a bot in a separate builder, then placing its Webchat on WordPress by pasting an embed code through a snippet plugin, as its docs show.
ChatBot.com
Best for: A hosted AI agent that answers visitors from your own content and aims to turn them into customers, the vendor says, installed through its plugin.
CustomGPT.ai
Best for: Answering visitor questions from your own site content, added through its WordPress plugin or by pasting an embed code into any page.
Jotform AI Agents
Best for: Teams already working in Jotform who want an AI customer-service agent, since its agents page lists an AI Chatbot for WordPress among its channels.
Kognetiks Chatbot
Best for: Owners happy to bring an API key from OpenAI, Anthropic or Google, who want visitor conversations turned into summaries they can read later.
Want AI doing the heavy lifting in your marketing?
I build the systems that handle the boring 80 percent, so you get your week back. Done properly, with the human kept in.
Landbot
Best for: Building a chatbot without code and adding it to WordPress by copying and pasting a snippet, which the vendor says is all it takes.
WPBot
Best for: A chatbot that also captures leads, runs forms and draws on a knowledge base, powered by OpenAI, Gemini, OpenRouter or Dialogflow, the listing says.

My advice before you add an AI chatbot
If you want control and you're comfortable managing an AI provider account, an in-WordPress plugin keeps the bot close to your content and settings. If you'd rather nobody on your side touches API keys, a hosted bot with a plugin is simpler, as long as you're happy for conversations to live on its platform. Use a snippet-based builder when you need flows the plugins can't do, and keep a note of where the snippet sits.
Whichever route you take, start with one clear job, such as answering common questions, rather than asking the bot to do everything. Our guide to chatbot builders covers more standalone options, and our list of AI agents for small businesses goes beyond chat.
What to give a bot before it goes live
- Your real answers. Feed it your own FAQs, service pages and policies, not just the home page.
- A way out to a human. Give visitors an email, form or contact page when the bot can't help.
- A privacy note. Tell visitors their messages may be processed by an AI provider, and update your privacy policy to match.
- A test run. Ask it the ten questions customers ask most, and fix any wrong answer before launch.
- A review habit. Read a sample of conversations each month and update its content where it struggled.

Frequently asked questions
Do WordPress AI chatbot plugins need an API key?
Many do. Plugins that run inside WordPress often ask you to connect an AI provider, such as OpenAI, Anthropic or Google, with your own key.
Where are chatbot conversations stored?
It depends on the route. A plugin may store them in your WordPress database, while hosted bots and embedded builders keep them on their own platform.
Can a chatbot answer from my own website content?
Several tools here say they can answer from your site content or a knowledge base. Check what content each one can read before you rely on it.
What's the difference between a chatbot plugin and an embed snippet?
A plugin installs through your WordPress dashboard. An embed snippet is code from an outside builder that you paste into your site, often with a snippet plugin.
Will changing my theme break my chatbot?
It can, if the bot's code was pasted into theme files. Adding snippets through a dedicated snippet plugin keeps them in place when you switch themes.
Should I tell visitors they're talking to an AI?
Yes. Say clearly that it's an automated assistant and offer a way to reach a person when the bot can't help.
