Website chatbot plugin development at Nexta, in short

An AI chatbot for website visitors is a chat widget that answers questions from your own pages, PDFs and price lists, captures leads and hands serious enquiries to your team. Nexta Web Solution builds it as a WordPress plugin, a Shopify app extension or a script for any site, with firm limits on what it may say. Builds start at ₹24,999 plus AI usage costs and usually take two to four weeks.

Why most website chat widgets get ignored

“Visitors leave without asking anything”

Do you deliver to Durgapur? Is there EMI? Are you open on Sunday? Simple questions, but nobody fills a contact form to ask them. They just close the tab.

“Our chatbot only says "leave your email"”

The widget you have is a glorified form. It cannot answer a single real question, so people ignore it.

“We are scared the AI will make things up”

Quoting a price you stopped offering last year, or promising a refund policy you never had, would cost more than the bot is worth.

“The free chat plugin made the site slow”

A heavy third-party script loads on every page before anything else, and your mobile speed score drops.

“Chat leads go nowhere”

Transcripts land in an inbox nobody checks. By the time someone calls back, the visitor has bought elsewhere.

What goes into an AI chatbot for your website

A knowledge base from your own content

We pull in your web pages, brochures, spec sheets and price lists, and you approve what goes in. When the site changes, the bot re-syncs on a schedule, so answers do not drift out of date.

Answers with guardrails

The bot answers only from retrieved content and links the page it used. If nothing matches, it says so and offers a person. Prices come only from your price sheet, and topics like medical or legal advice are blocked outright.

Plugin, extension or script

A proper WordPress plugin with its own settings page, written to WordPress coding standards. A Shopify theme app extension for stores. A small script or React component for custom sites. Each loads after the page becomes usable.

Lead capture that respects the visitor

The bot asks for a name and phone number only when the visitor wants a callback or quote, with a clear consent line. Leads go to your CRM, a Google Sheet, email or a WhatsApp alert to the right salesperson.

English, Hindi and Bengali

Visitors can type in English, Hindi, Bengali or the Roman-script mix most people actually use. The bot replies in the language they wrote in.

A dashboard that shows what people ask

Read transcripts, export leads, and see a list of questions the bot could not answer. That list is your next set of FAQs and website content.

Hand-off to WhatsApp or live chat

One tap moves the conversation to your WhatsApp number, or to a live agent during office hours, with the chat so far attached.

How we keep the bot honest and the site fast

You see and control the AI bill

The AI provider account, whether OpenAI, Anthropic or Google, is in your name with a spending cap. No hidden per-message mark-up from us, and you can see usage any day.

Speed is measured, not assumed

The widget loads late and light. We test your key pages in PageSpeed Insights before and after, and share both reports.

"I don't know" is a feature

A bot that admits a gap and offers a person keeps your reputation safe. We tune for correct answers, not for answering everything.

Your visitors' data handled carefully

Consent before collecting details, a retention period you choose, and the option to keep chat logs on an Indian server we run through TPHOST, in line with the Digital Personal Data Protection Act.

Is this right for you?

A good fit if

  • Sites with steady traffic and the same questions coming up again and again
  • Online stores fielding delivery, size and returns questions
  • Schools, coaching centres and colleges during admission season
  • B2B firms with long catalogues and spec sheets buyers struggle to search

Probably not the right fit if

  • Sites with very little traffic; work on SEO first so there are visitors to talk to
  • Questions that need a customer's account data when your site has no API; a WhatsApp bot or AI agent may suit better
  • Regulated advice such as diagnosis or legal opinions
  • Replacing every human in support

Website chatbot plugin development: frequently asked questions

Something else? Call +91 7500-4300-91 or WhatsApp us.

Our builds start at ₹24,999 plus GST. The price moves with the amount of content, the number of integrations, such as your CRM or WhatsApp, and whether you need a WordPress plugin or a fully custom widget. AI usage is billed separately by the provider, usually a modest monthly amount for small business traffic, and you can cap it.

Yes. On WordPress we build a real plugin with a settings page, not a pasted script. On Shopify we use a theme app extension so it survives theme changes. For custom or headless sites we provide a small script or component. If your site is on Wix or another builder, we check what it allows before quoting.

The bot answers only from content we retrieve from your approved sources, and it is told to say it does not know when nothing matches. Prices and policies come only from documents you sign off. We test it with tricky and off-topic questions before launch and read transcripts afterwards, tightening any answer that drifts.

A website chatbot catches people while they are browsing your pages, often before they have decided to contact you. A WhatsApp bot handles people who already message you, and can send updates later. Many businesses start with whichever channel gets more questions. The two can share one knowledge base, and the website bot can hand over to WhatsApp.

It should not, and we measure it. The widget loads only after the page is usable, and the heavy work happens on the server, not in the visitor's phone. We run PageSpeed Insights on your main pages before and after installation and share both results, so you can see the effect for yourself.

You and the staff you authorise. Transcripts and leads sit in your database, which can be on an Indian server we manage, and you choose how long to keep them. Visitors see a short notice and give consent before sharing personal details. The AI provider processes the text to produce answers, and we choose settings that keep it out of model training where offered.

Yes. It understands questions typed in Bengali or Hindi script and in the Roman-letter mix most people use on phones, and replies in the same style. We review a sample of answers in each language with native speakers before launch.

Yes, if you are an agency or software company. We can build a white-label WordPress or Shopify plugin with licence keys, settings for each site and update delivery. That is a larger project, quoted after a free call, and the code and brand stay yours.

Yes. We build website chatbots for clients in the UK, the Gulf, Australia and North America, with answers in English or Arabic content you provide. Quotes can be fixed in USD, GBP or AED, and we sign an NDA if you need one.
