Searching for the best WordPress AI chatbot plugins to create your own AI-powered chatbot? 🤔
With these plugins, you can connect models like OpenAI’s GPT series, Google’s Gemini, or Anthropic’s Claude to a chatbot that answers from your site’s content, not generic internet knowledge.
For example, you could train your chatbot on your site’s knowledge base so that it can answer visitors’ questions and point them to the right material. That way, you can offer quality support 24/7 without lifting a finger.
One quick honesty note before the list: when these plugins say “train,” they almost always mean retrieval-augmented generation (RAG). The plugin feeds your content to the AI model as context for each answer, instead of fine-tuning the model’s weights. For a support or sales chatbot, that’s exactly what you want, because the bot stays in sync with your content as you publish. 💡
In this post, you’ll find the five best WordPress AI chatbot plugins for exactly that job. Every one of them has a free version 💸 you can try before you buy, so let’s jump right in.
Five best WordPress AI chatbot plugins
Here are the picks for the best 🔥 WordPress AI chatbot plugins you can use right now:
- Hyve: the most direct “chatbot trained on your WordPress content” option, no API key required.

- AI Puffer: the former AI Power, an all-purpose AI toolkit with strong file-based training.

- MxChat: a focused chatbot plugin with wide training options and lifetime pricing.
In a rush? This table sums up the whole list:
| Plugin | Free version | Pro starts at | Best for |
|---|---|---|---|
| Hyve | ✅ | $99 (one-time) | Content-aware answers with zero API setup |
| AI Engine | ✅ | $79 / year | A full AI toolkit with multi-provider support |
| AI Puffer | ✅ | $9.99 / month | Training on PDFs and files, plus automation |
| WPBot | ✅ | $39 / year | Omnichannel chat (WhatsApp, Messenger, Telegram) |
| MxChat | ✅ | $69.97 (one-time) | Lifetime pricing and 100+ model choices |
⚖️ DISCLAIMER: Hyve is built by ThemeIsle, the team behind this blog. It leads this list because it matches the premise of this article (an AI chatbot trained on your own WordPress content) better than anything else right now. Every entry below gets the same honest treatment, drawbacks included.
1. Hyve
| Free version? | ✅ |
| Starting price for Pro | $99 (one-time, lifetime) |
| Model integrations | Hyve Connect hosted AI, or your own OpenAI key (GPT-4o mini and up) |
Hyve is the newest entry on this list and the only one built exclusively around the “trained on your own content” idea. Setup takes three steps: pick the posts, pages, and products the chatbot should learn from, choose how the AI runs, and the chat widget goes live. Edit a page later and Hyve re-indexes it automatically, so visitors never get an answer from an outdated version.
The thing that makes Hyve stand out right now is that an OpenAI account is optional. With Hyve Connect, the hosted AI option introduced in Hyve 2.0, the free plan includes 500 chat messages per month with no API key at all. If you’d rather bring your own OpenAI key, that works on every plan too: you pick the model, get unlimited messages, and pay OpenAI directly for what you use (here’s what that costs in practice). You can switch between the two at any time without losing your knowledge base.
Answers stream in as they’re generated, and the chatbot can link back to the page an answer came from, so visitors can verify what it says. The main drawback: the free hosted plan’s 500-message monthly cap won’t stretch far on a busy site, so heavier traffic means adding your own key or upgrading. You can read the story of how the first version was built if you’re curious where it started. 😎
Key features
- Train on your WordPress content (free): posts, pages, products, and custom post types, with automatic re-indexing on every edit.
- Two ways to power the AI (free): Hyve Connect hosted credits (500 messages per month on the free plan) or your own OpenAI key for unlimited messages.
- Conversation controls (free): welcome and fallback messages, content moderation, optional chat sound and timestamps.
- Flexible placement (free): floating bubble or inline chat via Gutenberg blocks, shortcodes, or sitewide visibility rules.
- Bigger knowledge base (Pro): import PDF, Word, Markdown, text, and CSV files, crawl external URLs or full sitemaps, and add private custom data.
- Proactive chat (Pro): messages triggered by time on page, scroll depth, or exit intent, plus suggested follow-up questions.
- Leads and integrations (Pro): in-chat lead capture with full conversation context, webhooks, and WooCommerce skills for live prices, stock, and order status.
Pricing
Hyve Lite is free on WordPress.org, with a knowledge base of 1,000 chunks (roughly 300 posts) that you can extend by connecting a free Qdrant vector database.
Hyve Pro raises the knowledge base to 10,000 chunks (about 3,000 posts) and the Hyve Connect allowance to 10,000 messages per month. It’s a lifetime license, not a subscription: $99 (€99) for one site or $279 (€279) for up to 50 sites, with a 30-day money-back guarantee.
2. AI Engine
| Free version? | ✅ |
| Starting price for Pro | $79 (per year) |
| Model integrations | OpenAI, Anthropic, Google, Mistral, and more, using your own API keys |
AI Engine is the most popular WordPress AI chatbot plugin in the WordPress.org directory, and it’s really a full AI framework rather than just a chatbot. Content generation, images, AI forms, automations, and, you guessed it, chatbots, all live under one roof.
It connects to OpenAI, Anthropic, Google, Mistral, and other providers through your own API keys, so you pick the exact model and pay the provider directly. For training, AI Engine can build a knowledge base from your site’s content with embeddings, and it also lets you supply your own dataset of prompts and answers (essentially a CSV of questions and ideal replies) to shape how the bot responds.
Jordy Meow’s documentation is some of the best in this space, which matters a lot if this is your first AI project. The honest trade-off: the feature set is huge, and the interface reflects that, so budget an afternoon to learn your way around. 👍
Key features
- Multi-provider chatbots (free): OpenAI, Anthropic, Google, Mistral, and more, with your own API key and full control over the model.
- Content-aware answers (free and Pro): train the bot on your site’s content with embeddings; the Pro version adds deeper training and fine-tuning options.
- Personality controls (free): customize the chatbot’s tone of voice and interaction style.
- Flexible display (free): run the chatbot sitewide or place it manually with shortcodes.
- Beyond chat (free and Pro): content and image generation, AI forms, and usage analytics, with Pro unlocking the advanced toolkit.
Pricing
AI Engine has a free version at WordPress.org that lets you create a working AI chatbot with your own API key.
AI Engine Pro starts at $79 per year for a single site, and lifetime licenses are available from $499 (five sites). Note that the entry price has moved up from the old $49 tier, so don’t trust older roundups that still quote it.
3. AI Puffer
| Free version? | ✅ |
| Starting price for Pro | $9.99 (per month) |
| Model integrations | OpenAI, Google Gemini, Microsoft Azure, OpenRouter, DeepSeek, xAI, or local Ollama, using your own API key |
Long-time WordPress users might know this one as AI Power: the plugin was renamed to AI Puffer, and it’s still the same all-purpose AI toolkit underneath. Alongside the chatbot you get a content writer, AI forms, an image generator, automations, and a set of WooCommerce AI tools.
Everything runs on a bring-your-own-key model with no hidden credits or markup. You connect OpenAI, Google Gemini, Microsoft Azure, OpenRouter, DeepSeek, xAI, or even a local Ollama install, and you pay the provider directly for what you use.
Training is a strong point: you can build the chatbot’s knowledge base from posts, pages, and WooCommerce products, then extend it with PDFs and uploaded files (Pro), which makes AI Puffer a good pick when your documentation lives outside WordPress. There’s also an optional web search toggle for real-time answers, and Pro can even embed the chatbot on external, non-WordPress sites.
Key features
- Your choice of provider (free): OpenAI, Gemini, Azure, OpenRouter, DeepSeek, xAI, or a local Ollama model, all with your own key.
- Train on your content (free and Pro): posts, pages, and products out of the box; PDF and file uploads to the knowledge base require Pro.
- Real-time answers (free): optional web search through OpenAI or Google when your content doesn’t cover a question.
- Voice options (free and Pro): voice input and playback in the chat, with a full real-time voice agent available in Pro.
- Full AI toolkit (free and Pro): content writer, AI forms, and image generator included; Pro adds form workflows, chatbot triggers, and integrations with Slack, HubSpot, Notion, Zapier, Make, and n8n.
Pricing
AI Puffer has a free version at WordPress.org that includes the chatbot, content writer, AI forms, and image generator.
AI Puffer Pro costs $9.99 per month for a single site, with multi-site licenses available, and a 7-day money-back guarantee. The old yearly and lifetime plans are gone, which is worth knowing if you read about them in older reviews.
4. WPBot
| Free version? | ✅ |
| Starting price for Pro | $39 (per year) |
| Model integrations | OpenAI, Google Gemini, OpenRouter, or DialogFlow, plus a built-in no-AI mode |
WPBot is the only plugin on this list that works perfectly well without any AI at all. It ships with a built-in, button-menu-driven bot for automated support, lead generation, and data collection at zero ongoing cost, and you can bolt an LLM on top whenever you’re ready. ⚡
When you do want AI, WPBot connects to OpenAI, Google Gemini, OpenRouter (which unlocks Claude, Grok, DeepSeek, Mistral, Llama, and more), or Google’s DialogFlow, and you can train the bot on your website data through the OpenAI connection. No code needed at any point.
The other standout is channels. WPBot Pro extends the same bot to Facebook Messenger, Instagram, Telegram, and WhatsApp, plus CRM integrations like HubSpot and Fluent CRM, which goes beyond what any other plugin here offers. There’s also a WooCommerce integration so shoppers can browse products and check order details inside the chat.
Key features
- AI optional (free): run the built-in no-AI bot, or connect OpenAI, Gemini, OpenRouter, or DialogFlow with your own account.
- Train on your site data (free): teach the bot from your website content through the OpenAI integration.
- Omnichannel chat (Pro): the same bot on Facebook Messenger, Instagram, Telegram, and WhatsApp.
- WooCommerce support (Pro): shoppers can view products and order details right in the chat window.
- Agency-friendly (Pro): white labeling and multi-site options on the higher tiers.
Pricing
WPBot has a free version at WordPress.org that covers the built-in bot and the AI connections.
WPBot Pro starts at $39 per year for the Starter plan, with Professional at $99 and Master at $189 per year. Lifetime licenses run $149, $279, and $369 for the same three tiers, so a one-time purchase is on the table if you prefer it.
5. MxChat
| Free version? | ✅ |
| Starting price for Pro | $69.97 (one-time, lifetime) |
| Model integrations | OpenAI, Claude, Gemini, Grok, DeepSeek, and 100+ models via OpenRouter |
MxChat is the smallest plugin on this list by install count, but also one of the most focused: it’s a dedicated AI chatbot plugin with a perfect five-star rating, built by people who clearly think about RAG a lot.
The training options are the widest here. Point MxChat at your sitemap and it ingests the whole site, or feed it PDFs, URLs, YouTube videos, WooCommerce products, or manual question-and-answer pairs. On the model side, you connect OpenAI, Claude, Gemini, Grok, or DeepSeek directly, or go through OpenRouter for access to more than 100 models with a single key.
Two more things stand out. There’s a live agent handoff through Slack (Pro), so a human can take over when the AI is out of its depth, and the pricing is a straight lifetime deal, which is rare for a plugin that’s updated as often as this one. 🎯
Key features
- Wide training sources (free): sitemap ingestion, PDFs, URLs, YouTube videos, WooCommerce products, and manual input.
- Model freedom (free): OpenAI, Claude, Gemini, Grok, and DeepSeek directly, or 100+ models through OpenRouter, with your own key.
- Live agent handoff (Pro): escalate conversations from AI to a human via Slack.
- Built-in content generator (free): draft blog posts and landing pages with images and SEO metadata.
- Lifetime pricing (Pro): a one-time payment instead of another monthly subscription.
Pricing
MxChat has a free version at WordPress.org that includes the chatbot and the core training features.
MxChat Pro is a $69.97 one-time payment with lifetime updates. Agency bundles bring the per-site cost down: $174.97 for five licenses or $279.97 for ten.
