AI Development Company for LLM Apps, AI Agents and Chatbots
We design and build AI features that do real work inside your product and operations: LLM integrations, AI agents, chatbots, machine-learning models and intelligent automation. CodeSWI is based in Hasbrouck Heights, New Jersey, and works with companies across the USA.
- You want to add LLM features (search, summarization, assistants) to an existing product.
- Your team spends hours on repetitive work an AI agent or automation could handle.
- You have data and need a predictive model or analytics built on it.
- You have an AI prototype that needs to become reliable, production software.

Frequently asked questions
Which AI models do you work with?
We pick the model for the job: hosted models such as OpenAI GPT and Anthropic Claude, or open-source models when you need to run them yourself. LangChain, TensorFlow and PyTorch cover orchestration and custom training.
Can you build on our existing systems and data?
Yes. Most AI work connects to what you already run: your database, documents, CRM or support tools. We map those integrations during discovery so they are in the scope and timeline from day one.
