AI Chatbot Development
Naman Gundaniya builds AI chatbots grounded in your own data — support assistants, lead qualifiers and in-app copilots that answer from your documents rather than the model's imagination. The engineering that matters is invisible: retrieval quality, hallucination control, human escalation, and a cost per conversation you can live with.

Who this is for
- Support teams answering the same questions hundreds of times a month
- Products adding an in-app assistant that actually knows the product
- Businesses that want a lead qualifier working around the clock
- Teams burned by a chatbot that confidently made things up
What you get
- A production chatbot answering from your documents and data (RAG)
- Escalation to a human with full conversation context when it can't answer
- Guardrails against off-topic, unsafe and invented answers
- Web widget, in-app or WhatsApp deployment
- An admin view of conversations, unanswered questions and knowledge gaps
- Cost per conversation instrumented from day one
- 30 days of post-launch support
Grounded in your data, not the model's memory
A model answering from its training data will eventually invent your refund policy. The fix is retrieval-augmented generation: the bot searches your actual documents, answers only from what it found, and cites the source. That moves the quality question from 'how smart is the model' to 'how good is the retrieval' — chunking, embeddings and reranking tuned to your content — which is engineering you can measure and improve, rather than behaviour you can only hope for.
The escalation path is a feature, not a failure
The worst chatbot answer is a confident wrong one; the second worst is a dead end. When the bot cannot answer from its sources, it says so and hands the conversation to a human — with the full transcript and the retrieved context attached, so the customer never repeats themselves. Every unanswered question is also logged and reported, which turns the bot into an instrument that shows you exactly where your documentation is thin.
Where the bot lives matters
A website widget suits support and lead capture; an in-app copilot can see the user's context and act on it; WhatsApp meets customers where they already are, which matters in the Gulf and India in particular. The channel decision shapes the build — session handling, identity, what the bot is allowed to know about the person typing — so it is made at design time, not bolted on after the widget ships.
Cost per conversation is a design decision
Token spend is architecture. Routing routine questions to a cheaper model and hard ones to a capable one, caching stable prompt prefixes, and retrieving passages instead of stuffing whole documents into context routinely changes the monthly bill by an order of magnitude. Every conversation is instrumented for cost from day one, so you see the number per conversation on a dashboard — not as a surprise on an invoice.
How the engagement works
- 01
Discovery
Identify the questions the bot must answer, the sources of truth for them, and the conversations that must go straight to a human.
- 02
Design
Define the retrieval sources, tone, refusal behaviour and escalation rules, with an evaluation set of real questions built alongside.
- 03
Build
Implement retrieval, prompting and the interface, then test against the evaluation set and a pilot group before public launch.
- 04
Ship
Launch with conversation analytics, cost tracking and gap reporting, plus 24-hour response times for 30 days after launch.
Technology
- Models
- The OpenAI, Claude and Gemini APIs, routed by task — a capable model for hard questions, a cheaper one for routine ones.
- Retrieval
- Chunking, embeddings and reranking tuned to your documents; Supabase pgvector or Convex for the index, LangChain for the plumbing.
- Channels
- An embeddable web widget, native in-app integration, or WhatsApp via the Business API.
- Quality
- An evaluation set of real user questions, hallucination checks against sources, and analytics on unanswered queries so the knowledge base grows where it is weak.
Proof
Loop - Messenger with AI Chatbot
Loop is a cross-platform messaging app built with Flutter and Firebase, with real-time one-to-one and group chat plus an integrated AI chatbot. One Dart codebase targets Android, iOS and web, with Firebase handling auth, message persistence and live delivery.
ScanX - AI Note Taker
ScanX is an AI note-taking web app built with Next.js, Convex and LangChain. Users upload a PDF, the text is chunked and embedded into a vector index, and a retrieval-augmented chat answers questions against that document with citations back to the source pages.
Frequently asked
How do you stop the chatbot making things up?
Ground it in retrieval: the bot searches your documents, answers only from the passages it found, cites them, and refuses when the sources don't cover the question. Add schema-validated outputs and an evaluation set of real questions, and hallucination becomes a measurable failure rate you drive down — not a personality trait you apologise for.
Can it answer from our own documents?
Yes — that is the default architecture, not an add-on. Help articles, PDFs, internal wikis and database records get indexed for retrieval, and the bot answers strictly from that index with source citations. When your documents change, the index updates, so the bot's answers track your actual current policy rather than a snapshot.
What happens when it can't answer?
It says so and hands over to a human, passing the full conversation and the context it retrieved so the customer never starts again from scratch. Every unanswered question is logged and reported — which is how you find out what your documentation is missing, one honest 'I don't know' at a time.
What does a chatbot cost to run per month?
The drivers are conversation volume, model choice and how much context each answer needs. Routing, caching and retrieval keep the per-conversation cost low — typically small change per conversation rather than per-seat software pricing — and every build ships with per-conversation cost instrumentation. Real numbers for your volume get worked out on the free 30-minute scoping call.
How long does it take to launch?
A support or lead-qualification bot over existing documents typically launches in three to six weeks: retrieval and evaluation first, then a pilot with real users before it goes public. In-app copilots and WhatsApp deployments sit at the longer end because identity and channel plumbing take real work. The scoping call gives you a timeline against your actual sources.
