AI Chatbot Development That Survives Contact With Real Users

Retrieval-augmented chatbots grounded in your own data, tool-calling agents that take real actions, guardrails, and the evaluation harness that keeps quality from drifting. Built on GPT, Claude, and open models with Next.js and TypeScript.

When the demo works but production does not

Anyone can wire a chat box to an LLM API in an afternoon. The demo dazzles. Then a real customer asks a question your training data never covered, the bot invents a refund policy that does not exist, and now you have a support escalation instead of a deflection. The gap between a weekend prototype and a chatbot you can put in front of paying customers is almost entirely the unglamorous parts — grounding, guardrails, evaluation, and observability.

Production AI chatbot development is what closes that gap. Answers grounded in your actual documents with citations. Guardrails that keep the bot on-topic and refuse what it should refuse. An eval suite that catches a regression before it ships, not after a customer screenshots it. Logging that shows you exactly what the bot said, why it said it, and which source it pulled from. We build the boring parts so the impressive part actually holds up.

What we build

  • Retrieval-augmented generation (RAG) over your PDFs, docs, help center, tickets, and database with cited answers
  • Tool-calling agents that look up records, create tickets, schedule meetings, and trigger workflows through your API
  • Streaming chat UI in Next.js and React with markdown, code blocks, citations, and typing indicators
  • Multi-model routing — cheap model for easy turns, frontier model for hard ones — with automatic fallback
  • Prompt guardrails, output schema validation, refusal handling, and jailbreak resistance
  • Evaluation harness that scores every release against a fixed test set before it ships
  • Vector search on pgvector, Pinecone, or Qdrant with hybrid keyword-plus-semantic retrieval
  • Conversation memory, session persistence, and per-user context across turns
  • Human handoff — escalation to a live agent with full transcript context when the bot is unsure
  • Observability — token usage, latency, cost per conversation, and a transcript review dashboard

Our methodology

AI work starts with an eval set, not a prompt. Discovery produces a representative set of real questions and the answers a good bot should give. That eval set becomes the contract: every prompt change, model swap, and retrieval tweak is measured against it, so we are improving a number instead of arguing about vibes. The retrieval pipeline is built and tuned before the conversational layer, because a confident answer grounded in the wrong document is worse than no answer.

Two-week discovery → eval-set design and retrieval build → phased agent build (4 to 12 weeks typical) → guarded rollout with transcript review. You own the source code, the prompts, the eval suite, and the deployment, and you bring your own model API keys.

Where chatbots earn their keep

The chatbots that pay for themselves are not the ones that try to do everything. They are scoped to a job: deflecting tier-one support tickets with cited answers, helping a sales team draft proposals, letting staff query an internal knowledge base in plain English, or guiding a customer through onboarding. We scope the job first and build the narrowest agent that does it well, then expand.

Every chatbot we ship is grounded, evaluated, and observable, so when a stakeholder asks "why did it say that?" there is an answer in the logs. That auditability is what lets you put an AI in a regulated workflow without inheriting a compliance problem.

AI chatbot development served from Macon, GA, with clients across Atlanta, New York, San Francisco, and the rest of the US.

Pricing

Fixed-fee per scope. Typical ranges:

  • Single-purpose RAG support bot over your help center: $10k – $25k
  • Internal knowledge-base assistant with auth and access control: $18k – $45k
  • Tool-calling agent that takes actions through your API: $30k – $70k
  • Multi-channel deployment (web + Slack + widget) with handoff: $35k – $90k
  • Discovery sprint with eval set and retrieval prototype: $3,500 flat

Model API usage is billed to your own provider account at cost — no per-message markup. 30-day post-launch support included, with an optional retainer for prompt tuning and new tools.

What you get

  • Full source code repository in your GitHub organization
  • Prompt library, retrieval pipeline, and the evaluation suite that scores quality
  • Production deployment with a staging environment for prompt and model testing
  • Transcript review dashboard with token usage, latency, and cost-per-conversation metrics
  • 30-day post-launch support — prompt tuning, retrieval fixes, and model updates
  • Guardrail and refusal policy documentation so stakeholders know the boundaries
  • Your own model API keys wired in — no markup, no lock-in, full portability

FAQs

Which model should we use — GPT, Claude, Gemini, or open source?

It depends on the task, the data residency requirements, and the budget. We benchmark candidates against your actual prompts and an eval set, then pick on quality, latency, and cost per conversation. Many production systems route easy turns to a cheap model and escalate hard ones, and we build that routing in.

Can the chatbot answer from our own documents and data?

Yes. We build retrieval-augmented generation pipelines that ingest your PDFs, help-center articles, database records, and tickets, chunk and embed them, and ground every answer in citations. The bot says when it does not know instead of hallucinating, which is the difference between a demo and something you can ship.

How do you stop the bot from making things up or going off the rails?

Grounded retrieval with citations, system-prompt guardrails, output schema validation, refusal handling, and an evaluation harness that scores every release on a fixed test set. We also add input filtering and rate limiting so the bot cannot be jailbroken into a liability or run up your token bill.

Can the chatbot take actions, not just answer questions?

Yes. Tool-calling agents can look up an order, create a ticket, schedule a meeting, or trigger a workflow through your API. We scope every tool with permissions and confirmation steps so the agent does useful work without doing dangerous work.

Do we own the code and the prompts?

Completely. You get the GitHub repository, the prompt library, the eval suite, the retrieval pipeline, and the deployment configuration. You bring your own model API keys, so there is no per-message markup and no platform lock-in.
