AI chatbot development services
AI chatbot development services: customer support chatbots on your website and in your app, chatbots on WhatsApp, Telegram, Messenger and Instagram, internal assistants in Microsoft Teams and Slack, sales and booking bots, and AI added to Intercom, Zendesk and Freshdesk, grounded in your own content and connected to your systems, with dedicated chatbot developers for your team or a chatbot delivered end to end.
Chatbots we build
Website and in-app support chat
A chat widget or in-app assistant that answers from your help centre and the customer’s account, streams its replies, keeps the conversation history and hands over to a person with a summary when it cannot help.
WhatsApp, Telegram and Messenger bots
Bots on the WhatsApp Business Platform, Telegram, Messenger and Instagram, with templates approved for outbound messages, voice notes and images handled, and opt-outs respected.
Internal assistants in Teams and Slack
Assistants that answer HR, IT and policy questions, find documents and file requests, signed in with the employee’s own account so they see only what that person may see.
Sales and booking bots
Bots that answer product questions, qualify the visitor, book a meeting or a table and log the lead in your CRM, passing the conversation to sales when it matters.
AI in your help desk
The AI agents in Intercom, Zendesk and Freshdesk set up on your content, extended with custom actions that call your systems, and measured on resolution rate rather than deflection alone.
Multilingual chat
One bot answering in English, Ukrainian, German, Spanish or whatever language your customers write in, grounded in your content in whichever language it exists.
Conversation design
Greetings, clarifying questions, tone and hand-off rules written with your support team, and the limits the bot keeps: what it never promises, discusses or decides.
Chat analytics
Conversations labelled by topic and outcome, unresolved questions reported and satisfaction tracked, so the next improvement is chosen from data.
Safety and privacy
Prompt-injection and abuse tests before launch, personal data masked in logs, retention set to your policy, and a clear notice that the user is talking to an AI.

Chatbots that know when to hand over
A good bot resolves the common questions and hands the rest to a person quickly, with the context already written down. We set the hand-off rules with your support team, measure resolution and satisfaction, and widen what the bot handles only when the data shows it can.
Answers come from your content and your systems, not from the model’s memory, and every reply can be traced to its source. Before launch the bot is tested on real conversations, including attempts to make it promise discounts, reveal data or wander off topic.

Questions about AI chatbot development
Can the same chatbot work on our website and on WhatsApp?
Yes. One conversation engine serves every channel, with the channel-specific parts, such as WhatsApp templates or Teams cards, handled at the edge, so the answers stay the same wherever the customer writes.
Can you improve the AI in Intercom or Zendesk instead of building a new bot?
Yes. Often the quickest gain is better content and custom actions in the help desk you already use. We build a separate bot when you need channels, data access or control that the help desk does not offer.
How do you stop it from making things up?
By grounding answers in retrieved sources and showing the citations, instructing the model to say when the sources do not answer the question, and keeping unanswerable questions in the evaluation set. That reduces invented answers and measures what is left; no current model removes them entirely.
How quickly can chatbot developers start?
When the right chatbot developer is available, the start is gated only by your interview and the NDA and IP assignment. Otherwise we run a search, which typically produces candidate profiles within two to three weeks, and nobody starts until you have said yes.
How do we hire chatbot developers through BigTree108?
Tell us the work, the seniority and the hours you need. We propose one or two people with their profiles, you interview them the way you would interview your own hire, and you sign one agreement with BIG TREE 108 LLC and receive one invoice a month.
Who owns the work they produce?
You do. Every specialist has a signed contract with BigTree108 that assigns all work product to the company, and our agreement with you assigns it onward. Code, designs and documents are delivered into your own repositories and tools, not kept where only we can change them.
Planning a chatbot?
Tell us the channels, the questions it should answer and the systems behind them. You get an answer within one business day: a plan, candidate profiles, or a review of the bot you already run.
