How to Add an AI Chatbot to a Small Business Website (No Code)
To add AI chatbot to website pages without writing code, you need about an afternoon: pick a tool, point it at your pages, paste one script into your site, then test it hard before visitors see it. The two decisions that matter are which tool bills the way your traffic behaves, and when the bot hands a chat to a human. This guide compares three common no-code options, Tidio, Chatbase and Intercom Fin, using their published pricing as of October 2026.
Before you start: what you need
- A list of real questions. Pull the last month of emails, contact-form messages and DMs. Most small businesses find the same 20 to 30 questions repeat: hours, delivery times, pricing, returns, booking.
- Pages that answer them. A chatbot trained on your site can only be as accurate as the site. If your returns policy isn't written down anywhere, write it first.
- Admin access to your site. You need to add a script to the footer (any site builder) or install a plugin (WordPress).
- A named human. Someone has to receive the chats the bot can't handle, and someone has to read transcripts each week.
Step-by-step: add ai chatbot to website
1. Write down the questions the bot should answer
Sort your question list into three piles: safe to automate (opening hours, shipping zones), automate with a hand-off (order problems, quotes) and human only (complaints, refunds over a set amount, anything medical, legal or financial). The third pile becomes your hand-off rules in step 4.
2. Pick a platform
The three tools below are built for different shapes of business. The comparison section further down covers pricing; the short version is that Tidio pairs an AI agent with a live-chat inbox, Chatbase is a standalone AI agent billed by message credits, and Intercom Fin charges per resolved conversation on top of help-desk seats.
3. Feed it your content
Both Chatbase and Tidio can learn from your site. According to Chatbase's data-sources docs, you can crawl a full site from the homepage, submit an XML sitemap or add single URLs, and exclude paths or individual links to control what gets used. The docs say there is no retrain button: new sources are picked up within seconds, and Standard and Pro plans add a weekly auto-resync. Tidio's help centre says Lyro's knowledge base can take website URLs, manual Q&A pairs and imported files, with an option to re-sync a URL after you update the page.
Start narrow. Feed in your FAQ, pricing, shipping and policy pages, not every blog post. Fewer, clearer sources give fewer confused answers.
4. Set the hand-off rules
Write short instructions in the bot's settings: "If the visitor asks about a refund, an order that hasn't arrived, or is upset, say a team member will reply and ask for their email." If you use a tool with a live-chat inbox, route those chats there. If not, collect contact details and forward them by email.
5. Install the widget
Every platform gives you a script snippet.
WordPress. Chatbase has an official plugin in the WordPress plugin directory: install it, copy your chatbot ID from Chatbase's settings tab and paste it under Settings, then Chatbase Options. For other tools, a header-and-footer plugin or your theme's footer setting will hold the script.
Ghost. Go to Settings, then Advanced, then Code Injection, and paste the script into Site Footer, which Ghost's own tutorial recommends for JavaScript. It then loads on every page.
Wix, Squarespace, Shopify. Each has a custom-code or app-store route. Check the vendor's install page for the exact steps for your builder.
6. Test and review weekly
Before launch, try to break it. Ask about a product you don't sell, a price that changed last month, and a complaint. Ask the same question three different ways. After launch, read real transcripts every week for the first month and add missing answers to your source pages.
Example: Tidio vs Chatbase vs Intercom Fin at about 500 chats a month
All prices below are as of October 2026, per each vendor's pricing page, and change often. Treat this as a way to estimate, not a quote.
Tidio
Tidio's free plan covers 50 billable conversations a month. Paid plans start with Starter at $24.17 a month billed annually (100 billable conversations, plus 50 one-off Lyro AI conversations) and Growth from $49.17 a month for up to 2,000 billable conversations. The Lyro AI agent is a separate add-on listed from $32.50 a month for 50 conversations, and the price rises with volume. At 500 AI-handled chats you'd need a Lyro tier well above the entry level; use Tidio's pricing slider for the exact figure. Paid plans have a 7-day trial with no card required.
Good fit: shops and service businesses that want a human live-chat inbox and AI in one place.
Chatbase
Chatbase bills by message credits, not conversations. The Free plan gives 50 credits a month and one agent; note that Chatbase says free agents are deleted after 14 days of inactivity. Hobby is $40 a month for 700 credits, and Standard is $150 a month for 4,000 credits. Extra credits are $40 per 1,000.
The worked example: 500 chats with an average of four bot replies each is roughly 2,000 replies. If each reply used one credit, that sits above Hobby and inside Standard. Credit use per reply can vary by model, so check Chatbase's credit rules before you commit.
Good fit: owners who want a smart FAQ bot and are happy to forward hand-offs by email.
Intercom Fin
Intercom lists Fin at $0.99 per outcome, counted when a customer confirms the answer resolved their question, doesn't ask for more help, or Fin completes a workflow. Help-desk seats are $29 per seat a month on Essential and $85 on Advanced, billed monthly. If Fin resolved 300 of your 500 chats, that's about $297 in outcomes plus at least one seat, so roughly $326 a month.
Good fit: businesses that already run support in Intercom or expect to grow into a full help desk.
Mistakes to avoid
- Training on everything. Old blog posts with outdated prices produce outdated answers. Exclude them.
- No visible human option. A bot that loops is worse than a contact form.
- Pretending to be a person. Label it as an AI assistant in the greeting.
- Forgetting to re-sync. Change a price on your site and the bot keeps quoting the old one until you re-sync.
- Ignoring cost per chat. Per-outcome and per-credit billing both scale with traffic. Set a budget alert if the tool offers one.

When not to use AI for this
Skip the AI bot, or keep it to FAQs only, if most of your enquiries are bespoke quotes, sensitive personal matters or high-value sales where a wrong answer costs more than a slow one. A booking widget may do more for an appointment-based business than a chatbot does; see our guide to an AI scheduling assistant for small business. And if your total volume is a handful of chats a week, a well-written FAQ page and quick human replies are cheaper.

FAQ
How much does an AI chatbot cost?
As of October 2026 you can start free on Tidio or Chatbase with small limits. Paid plans run from about $24 to $150 a month at small-business volumes, and Intercom Fin charges $0.99 per outcome on top of seat fees, per each vendor's pricing page.
Can I train a chatbot on my website content?
Yes. Chatbase can crawl a whole site, a sitemap or single URLs, and Tidio's Lyro can scan website URLs, take manual Q&A pairs and import files. Re-sync whenever you change prices or policies.
Do AI chatbots hurt customer trust?
They can when they guess, hide the human option or pretend to be a person. Tell visitors they are talking to an AI, keep answers tied to your own content and make reaching a person easy.
Conclusion
Start with the free tier of whichever tool matches how you want to be billed: Tidio if you also want a live-chat inbox, Chatbase if you want a standalone FAQ bot. Train it on five or six core pages, write two hand-off rules, and read every transcript for the first two weeks before you widen what it covers.
