## Quick answer

To add an AI chatbot to WordPress, install a WordPress AI chatbot plugin that trains on your own content, connect an AI provider and let it build a knowledge base from your pages. Aisk is a free WordPress chatbot plugin that learns your pages, posts, PDFs and WooCommerce products and works as a 24/7 virtual assistant on your site, WhatsApp and Telegram.

Adding an **AI chatbot to WordPress** used to mean writing decision trees: if the visitor clicks "Shipping", show this answer. Modern **WordPress AI chatbot plugins** skip that. They read your site, build a knowledge base, and answer questions in plain language — a **virtual assistant** that knows your business.

Here's how to choose one and get it running.

## AI chatbot vs live chat plugin

These get confused, but they solve different problems:

| | WordPress live chat plugin | WordPress AI chatbot plugin |
|---|---|---|
| Who replies | A person on your team | AI, from your content |
| Availability | When someone's online | 24/7 |
| Best for | Complex, high-value conversations | Repetitive questions at any volume |
| Cost driver | Staff time, per-seat plans | AI usage |

Most sites benefit from both: the AI handles the repetitive questions, and hands off to a person when needed. Aisk does the handoff by showing your support details or opening a ticket.

## What to look for in a WordPress chatbot plugin

1. **Trains on your own content.** Pages, posts and FAQs at minimum — ideally PDFs, external URLs and custom text too.
2. **Easy to keep current.** One click to re-learn after you update content.
3. **WooCommerce support** if you sell online — product search and order lookup, not just text answers.
4. **Human fallback** — contact details or tickets when the AI isn't sure.
5. **Channels** beyond the website, like WhatsApp and Telegram.
6. **Clear pricing.** Watch for message caps and features locked behind Pro.
7. **WordPress.org listing.** Plugins in the official directory are reviewed against its guidelines and update through your dashboard.

## What a WordPress virtual assistant can handle

- **Business sites:** services, pricing, opening hours, booking questions, directions
- **Online stores:** product questions, recommendations, order status, shipping and returns
- **Content sites:** finding the right article or guide
- **Membership and course sites:** how-to and account questions from your documentation

Anything it can't answer becomes a support ticket — and a hint about what content to add.
