Free AI Chatbot for WordPress

Updated August 2026 · 5 min read

"Free" in the chatbot world usually means a 14-day trial with your credit card on file. This guide is about a different kind of free: a free plan that stays free, works on WordPress in minutes, and answers your visitors from your own content.

What "free forever" actually includes

The ChatNest Free plan is not a trial with a countdown. It includes:

• 1 chatbot — branded with your name, avatar and colour
• 100 AI messages per day — around 3,000 conversations' worth of Q&A a month for a typical small business
• Knowledge-base training — paste business info, add FAQs, set behaviour rules, or crawl your own site
• Live inbox with human takeover — step into any conversation when a visitor needs a person
• Website widget — the embed that works on WordPress and everywhere else

No credit card. No trial clock. No API keys to configure.

Why the free tier exists

Managed AI chatbots have a cost per message. Most companies hide that behind trials; ChatNest gives you a real free tier because a bot that proves itself on your site is worth more than a forced upgrade. When you outgrow 100 messages a day, paid plans from £15/month add capacity — but you decide when, not a countdown timer.

Set it up on WordPress in three steps

1. Install the plugin. Download the ChatNest plugin, upload it via Plugins → Add New → Upload Plugin, and activate it.
2. Create your free chatbot. Sign up at chatnest.uk, create a chatbot and train it — paste your business info and a few FAQs, or let it crawl your website.
3. Paste the token. Copy the 32-character token from Chatbots → Embed, paste it into Settings → ChatNest AI Chatbot, and save. The widget is live on every page.

What 100 messages a day really means

Most visitors don't chat — they browse. For a business doing a few hundred visitors a day, a bot that resolves the top ten questions will rarely brush the cap. And because the bot answers from your content, fewer messages end in frustration and repeat questions. If you do hit the ceiling, the dashboard makes the upgrade obvious — no digging.

Can you really run a business on free?

Yes, for the core use case: answering the same questions every visitor asks, at any hour. The bot never sleeps, never queues, and the human takeover means you're always in control. When volume grows — more chatbots, more messages — the Starter, Growth and Professional plans are there. But you could run a year on the free plan without it costing a penny.
