Most chatbots are just wrappers. I build conversational AI systems that actually work - with memory, context awareness, and production-grade reliability.

Whether you need a customer support bot, an internal knowledge assistant, or an AI companion for your SaaS, I design and build the full system: LLM integration, conversation memory, streaming UI, and backend infrastructure.

Session-persistent chatbots (users pick up where they left off)

RAG chatbots (your bot answers from your actual data, not hallucinations)

Streaming response UIs for real-time conversation feel

Multi-turn conversation with proper context window management

System prompt engineering tailored to your product's persona

Tool use and function calling (bot can look things up, trigger actions)

Admin view to monitor conversations and track bot performance

OpenAI GPT-4o - Anthropic Claude - Groq (Llama / Mixtral) - Ollama (self-hosted) - LangChain - Vercel AI SDK - Next.js - Node.js - PostgreSQL - TypeScript

You describe what the bot needs to do and where it lives (web app, site, internal tool)

I scope the system: LLM choice, memory architecture, data sources, UI approach

I build, test with real conversations, and hand over with documentation

$800 covers a standard session-persistent chatbot with streaming UI. RAG or multi-agent systems are quoted after scoping.

My development fee covers building the chatbot. Running it requires an API key from your chosen provider - billed directly by them, not by me. I help you pick the right model for your budget during scoping.

Rough monthly estimates based on usage:

Light use (under 1,000 messages/month): $1 - $20/month

Moderate use (1,000 - 10,000 messages/month): $10 - $100/month

Heavy use (10,000+ messages/month): $100 - $500+/month

GPT-4o mini and Claude Haiku are the right starting point for most products. If you want near-zero API costs, I can build with open-source models via Groq - same reliability, fraction of the price. If your data cannot leave your servers, Ollama on your own infrastructure is a fully private, production-grade option. We decide together during scoping.
