What We Build
What can we build with AI chatbots?
Eight categories of AI chatbot work, from web support widgets to multilingual WhatsApp deployments and voice-enabled assistants.
Reference Architecture
Which architecture do we use for AI chatbot development?
Six layers we wire together on every greenfield AI chatbot. Each layer is testable, observable, and replaceable as models and tools evolve.
Conversation
LangGraph orchestrator with intent detection, persona prompting, multi-turn memory, and explicit fallback to human handoff. Channel-aware UX across web, WhatsApp, Slack, and voice.
RAG Knowledge
Ingest of your docs, FAQs, product catalog, and APIs into Pinecone, Qdrant, Weaviate, Chroma, or pgvector. Hybrid search with reranking. Citations on every answer.
Tool Calling
Typed function calling against your CRM, helpdesk, payments, and internal APIs. Input validation, retries, per-tool cost ceilings, and structured logs of every call.
Safety
PII redaction before tokens leave your VPC. Prompt injection guards, refusal policies, rate limits, and audit trails. BAA-eligible deployments on Azure OpenAI and AWS Bedrock.
Observability
LangSmith, Langfuse, or Helicone wired for traces, cost, and latency on every conversation. KPI dashboards for CSAT, deflection rate, and cost per resolved conversation.
Evaluation
Ragas and DeepEval harness for grounding, faithfulness, and answer relevance. Regression gates on every release. Hallucination budget agreed before launch.
Prompts, evals, and infrastructure as code in your repository on day one

Frequently Asked
AI Chatbot Development FAQs Product Leaders Ask Up Front
Pricing, accuracy, channels, languages, privacy, integrations, and ongoing maintenance, answered straight.
How much does AI chatbot development cost?
Fixed-scope MVPs start at $15,000. Production chatbots with RAG, function calling, and one or two channels run $40,000 to $120,000. Enterprise multi-channel deployments with voice, WhatsApp, Slack, and CRM integrations start at $150,000. Or hire a senior AI engineer monthly from $1,650, hourly from $24.
How long does it take to build an AI chatbot?
A scoped MVP ships to staging in 4 to 6 weeks and to production in 8 to 10 weeks. Production chatbots with RAG, eval harness, and observability take 10 to 16 weeks. Enterprise multi-channel deployments run 4 to 8 months. Working chatbot at the end of every two-week sprint.
How do you control hallucinations and keep accuracy high?
Three layers. RAG grounds answers in your documents only. A Ragas and DeepEval harness measures faithfulness, grounding, and answer relevance on every release. Out-of-scope queries route to fallback or human handoff. We publish a confusion matrix and ship below an agreed hallucination budget before launch.
Which channels can the chatbot live on?
Web widget, WhatsApp Business API, Telegram, Facebook Messenger, Instagram DM, Slack, Microsoft Teams, SMS, voice via Twilio and Vapi, and in-app SDKs for iOS and Android. One brain, many channels, channel-aware UX.
How many languages do you support?
GPT-4o and Claude 3.5 Sonnet are strong out of the box in 30+ languages. We have shipped chatbots in English, Spanish, French, German, Arabic, Hindi, Portuguese, Japanese, and Mandarin. Language detection and routing are built into the orchestrator.
How do you handle PII, HIPAA, and data privacy?
PII redaction before tokens leave your VPC. Self-hosted Llama 3 or Mistral when data residency rules forbid third-party APIs. BAA-eligible deployments for healthcare on Azure OpenAI and AWS Bedrock. SOC 2 friendly logging with field-level redaction in LangSmith and Langfuse.
Which CRMs, helpdesks, and tools do you integrate with?
Salesforce, HubSpot, Zoho, Zendesk, Intercom, Freshdesk, Jira, ServiceNow, Shopify, WooCommerce, Stripe, Twilio, Okta, and any REST or GraphQL API. Tool and function calling is wired with input validation, retries, and per-tool cost ceilings.
Do I bring training data or do you build it?
You bring whatever you have. We turn it into a retrieval corpus and evaluation set. If you have nothing, we synthesize a starter eval set from your top intents, then replace it with real conversation logs after week two of production. No fine-tuning unless retrieval and prompting cannot close the gap.
Will you sign an NDA and will I own the code?
Mutual NDA in 24 hours. Code in your repository from day one. IP transfers to you in every SOW. Prompts, evals, embeddings index, infrastructure as code, all yours. Our engineers push commits as named contributors on your GitHub, GitLab, or Bitbucket org.
Do you offer post-launch maintenance?
Yes. Same team on monthly retainer. Prompt tuning, new tools, model upgrades, quarterly RAG refreshes, and 24x7 incident response tiers. Model swap-outs from GPT-4o to Claude 3.5 or Llama 3 happen behind the orchestrator without touching channel code. 90 percent of clients extend past 12 months.
