An AI chatbot builder that works from your content, not from a flow diagram. Add your website and documents, set the tone and the rules in plain words, test it with real questions, put it live. An afternoon, no code.
An AI chatbot builder lets you make a chatbot without a developer. Most builders give you a canvas where you draw every branch of the conversation. SimplyBoost's builder is a form: you give the agent your website, PDFs and FAQs, choose a role and a tone, write the rules in plain words, and it answers from that content. Install it with one script, the WordPress plugin, the Shopify theme embed or Google Tag Manager, and connect WhatsApp and Instagram to the same agent. Three agents per account, a free 7-day trial, then €39, €89 or €169 a month.
- No code, no flow diagrams
- 3 agents on every plan
- Hosted in Europe

How the AI chatbot builder works, step by step
This is the setup guide every new account walks through. Most people are live the same afternoon.
- 1
Create the agent
Pick a role: customer support, lead generation, or commerce for a Shopify store. Name it, choose the tone and how long replies should be, and the language it replies in or let it follow the customer.
- 2
Give it your content
Paste your website or sitemap and it reads the pages. Upload PDFs, Word files, CSVs and text up to 50 MB each. Add the FAQs your team answers every week as question-and-answer pairs.
- 3
Write the rules in plain words
Instructions, not code: what to call the company, what never to promise, when to offer a person. Add the questions to show as chips when the chat opens.
- 4
Test it with twenty real questions
The twenty your customers ask most. Where it comes up short, add the page or document, or write the answer once in the Missing answers tab.
- 5
Put it live
One script, the WordPress plugin, the Shopify theme embed or Google Tag Manager for the website. Connect WhatsApp through Meta's signup and Instagram through a sign-in for the same agent.
What the builder reads, and how much
A chatbot is as good as what it may read. These are the limits per plan; a trial reads 50 pages.
| Source | What it is for | Limit |
|---|---|---|
| Website | Products, services, help pages, policies | Up to 150 pages on Starter, 500 on Growth, 1,500 on Pro; re-read daily or weekly if you want |
| Files | PDFs (scanned too), Word, CSV, text, Markdown, images | 50 MB per file |
| Text snippets | Opening hours, a policy, a fact not on the site | 200,000 characters each |
| Q&A pairs | The questions your team answers every week | As many as you need |
| Shopify | Catalogue, orders, carts | Synced on Growth and Pro |
| Your own systems | Stock, prices, planning | Pushed through the API as often as you like; needs a developer |
What you set, and what the builder decides for you
- Personality
- Name, tone, reply length, reply language. Formal or friendly, short or thorough.
- Instructions
- Plain-language rules the agent follows in every reply. What it may promise, what it must never say, how it signs off.
- Safety net
- When it hands over to a person: a request for a human, a complaint, a refund, two unanswered questions in a row, or any of up to 20 keywords you pick. Where the alert goes: email, dashboard, Slack, or a Zendesk, Freshdesk or Gorgias ticket.
- Lead capture
- Which details to ask for (name, email, phone, company), which are required, and the email you get for each new lead.
- Decided for you
- The agent answers only from your sources and says so when it cannot; the newest source wins when two disagree; links and images in replies come only from your content.
AI chatbot builders compared
Prices as each vendor publishes them on its pricing page, in its own currency. Last checked: 15 September 2026.
| Builder | What you build with | Entry price | What the price counts |
|---|---|---|---|
| SimplyBoost | A form: content, tone, rules. No canvas | €39 a month (€31 billed yearly), free 7-day trial | 500 AI replies a month, 3 agents, website, WhatsApp and Instagram included |
| Chatbase | Content sources plus actions | Hobby $40 a month | 700 message credits a month, 1 agent, $25 a month for each extra |
| Tidio | A flow builder plus the Lyro AI add-on | Starter $24.17 a month, Lyro from $32.50 a month | Conversations on the plan, Lyro conversations on the add-on |
| ManyChat | A flow canvas for Instagram, Messenger and WhatsApp | Essential $17 a month | 250 active contacts, more per contact over the limit |
The honest line: SimplyBoost has no visual flow builder. If your use case is a scripted sequence with branches (a quiz, a multi-step form), a flow tool fits better. If it is answering questions from your content and handing over when needed, a form is faster to build and to maintain.
Is there a free AI chatbot builder?
What free usually means
- A free plan with a hard cap and the vendor's branding on your site
- A free trial that ends in a paid plan
- Open-source software that needs a developer and a server
With SimplyBoost
- A free 7-day trial with 100 AI replies, no card needed
- No permanent free plan
- Then €39 a month, the same for any team size
What to check in any free tier
- Whether the chatbot can read your own content or only a few pasted answers
- Whether it shows the vendor's logo to your customers
- What happens to conversations when the cap is hit
AI chatbot builder questions
With SimplyBoost: create an agent, paste your website and upload your documents, set the tone and the rules in plain words, test it with your customers' real questions, and install it with one script or the WordPress plugin. There is no canvas and nothing to program.
Yes. It reads your website (up to 150 pages on Starter, 500 on Growth, 1,500 on Pro), PDFs, Word files, CSVs and text up to 50 MB each, Q&A pairs, and a Shopify catalogue. It answers only from those sources.
SimplyBoost has a free 7-day trial with 100 AI replies and no permanent free plan. Free tiers elsewhere usually cap replies hard and show the vendor's branding to your customers; check both before you choose one.
No. SimplyBoost is built on content and rules rather than drawn flows. For a scripted sequence with branches, a flow builder such as Tidio or ManyChat fits better; for answering questions from your content, the form is faster.
Your website (one script, the WordPress plugin, the Shopify theme embed or Google Tag Manager), WhatsApp through Meta's signup, and Instagram DMs. One agent, one knowledge base, all three.
Starter is €39 a month with 500 AI replies, Growth €89 with 2,000 and Pro €169 with 6,000. Three agents on every plan, no fee per seat or per resolution. Hosted in Europe.
