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
- Trains on your own content. Pages, posts and FAQs at minimum — ideally PDFs, external URLs and custom text too.
- Easy to keep current. One click to re-learn after you update content.
- WooCommerce support if you sell online — product search and order lookup, not just text answers.
- Human fallback — contact details or tickets when the AI isn’t sure.
- Channels beyond the website, like WhatsApp and Telegram.
- Clear pricing. Watch for message caps and features locked behind Pro.
- 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.
