What is ChatSys? The no-code AI chatbot that learns from your URL.
ChatSys is a no-code AI chatbot builder that turns any website into a 24/7 conversational AI agent in under 60 seconds. Paste your URL and ChatSys automatically crawls every page — product descriptions, pricing, FAQs, policies, blog posts — and trains a large language model on that content. No manual data upload, no developer, no prompt engineering required.
The resulting AI agent answers visitor questions in real time, handles support requests after hours, and transfers to a live human in one click when a high-value lead or complex issue appears. Paid plans begin at $19/month (Pro).
- Supported platforms:
- WordPress, Shopify, Webflow, Wix, Squarespace, React, Next.js, Framer, and plain HTML.
- AI models:
- Enterprise-grade LLMs; the Enterprise plan unlocks priority GPT-OSS-120B-class models.
- Compliance:
- TLS-encrypted and GDPR-ready, with isolated per-workspace data.
- Setup time:
- Under 60 seconds from URL to a live, trained agent.
Every unanswered question is a sale you already lost.
Visitors do not wait. They ask, they get crickets, and they buy from whoever answers first. Other bots still make you write your own training data. ChatSys just reads your site and starts answering.
Your busiest question hours are the ones nobody is staffed for.

Why response time kills conversions
- 35–50% of sales go to the vendor that responds first. (InsideSales Research, 2024)
- Respond within 5 minutes and you are 9× more likely to convert a lead. (Drift Conversational Marketing Report, 2024)
- 30–40% of chat volume arrives outside business hours — when no agent is staffed. (Intercom Benchmark Report, 2024)
- AI chatbots cut inbound support tickets by up to 40% on content-rich sites. (Zendesk CX Trends, 2025)

Frequently asked questions about AI chatbots for websites.
How do I add an AI chatbot to my website without coding?+
Paste your URL into ChatSys, pick which pages it learns from, and drop one line of embed code into your site — WordPress, Shopify, Webflow, Wix, or plain HTML. The whole thing takes about 60 seconds. No API keys, no training files, and no developer required.
Does it work on WordPress, Shopify, or Webflow?+
Yes — one line of code on any platform. ChatSys supports WordPress, Shopify, Webflow, Wix, Squarespace, React, Next.js, Framer, and plain HTML.
How much does an AI chatbot for a website cost?+
ChatSys Pro is $19/month (1 chatbot, 1,000 messages per month, 10 MB knowledge base, human takeover included) and Premium is $39/month (3 chatbots, 3,000 messages shared across the website widget and WhatsApp, 30 MB knowledge base, remove branding, voice notes, live web answers), with custom-priced Enterprise (SSO, SLA, dedicated account manager) on top. There are no per-seat fees and no per-message WhatsApp charges. On Premium, usage beyond the included 3,000 messages is billed at $19 per additional 5,000 rather than cutting your chatbot off. Pro and Premium include a 7-day free trial with no credit card required.
Can the AI chatbot answer on WhatsApp too?+
Yes. On Premium and Enterprise you can link a WhatsApp number to any agent by scanning a QR code — the same way you link WhatsApp Web. The agent then answers people who message that number using the exact same training, knowledge base and tone as your website chat, and those conversations land in the same inbox where you can take over by hand. It works with your existing WhatsApp number; there is no Business API application, no Meta approval, and no per-message fee.
What happens if I go over 3,000 messages on Premium?+
Your chatbot keeps answering — it never goes quiet mid-month. Usage past the included 3,000 is billed at $19 per additional 5,000 messages, added to your next invoice as its own line. So a month with 8,000 messages is $39 + $19 = $58, and a month with 12,000 messages is $39 + $19 + $19 = $77. Your dashboard shows the running total at any time, and we email you as soon as you cross the included allowance so the invoice is never a surprise. Pro is hard-capped instead: it stops replying at its limit rather than billing extra.
Do WhatsApp messages use my monthly message allowance?+
Yes — website chats and WhatsApp replies draw on one shared monthly allowance, so there is nothing extra to buy and no separate WhatsApp bill. Premium includes 3,000 messages per month across both channels.
How do AI chatbots improve website conversion rates?+
They close the response-time gap that loses sales. 35–50% of sales go to the vendor that responds first (InsideSales Research, 2024), and responding within 5 minutes makes you 9× more likely to convert a lead (Drift, 2024). A 24/7 AI agent answers instantly — including the 30–40% of questions that arrive after business hours.
What is the difference between a website chatbot and an AI agent?+
A traditional chatbot follows pre-written decision trees and only answers what it was scripted for. An AI agent uses a large language model to reason over your site's content and answer novel questions it was never explicitly programmed for. ChatSys agents also support one-click human takeover.
How accurate is it, really?+
It answers only from your scraped content and uploaded files. If it does not know, it says so instead of guessing — and can hand off to a human.
Which AI models power it?+
Enterprise-grade hosted models like Qwen 2.5 and GPT-OSS-120B — GPT-4o-class quality for support tasks at a fraction of the cost. The Enterprise plan unlocks priority models.
Can I talk to visitors myself?+
Anytime. Open the conversation, hit Take Over, and you are chatting live. The AI hands back when you are done.
Is my data private?+
Every workspace is isolated with row-level security and TLS encryption. Your content is never used to train models for anyone else. ChatSys is GDPR-ready.
How fast until it is live?+
About 60 seconds from pasting your URL. Training runs in the background while you customize the look.
Your competitors are still writing FAQ pages.
