AI agent development — smart assistants that actually work for your business.
We build AI-powered assistants that answer customer questions, handle support tickets, process orders, and automate repetitive tasks — using ChatGPT, Claude, Gemini, or your own data. Built with human oversight so you stay in control. All work through Upwork with payment protection.

AI agents for real business outcomes
We build AI agents for customer support (autonomous ticket resolution, refunds, escalation), sales (lead generation, personalized outreach, pipeline management), HR (resume screening, interview scheduling), finance (invoice matching, expense auditing), and internal workflows. Every agent includes human-in-the-loop oversight and audit trails for enterprise use.
LLM integration and RAG development
We integrate large language models (ChatGPT, Claude, Gemini, open-source LLMs) into your app or website. RAG (retrieval-augmented generation) pipelines connect your AI to your data — documents, databases, knowledge bases — so it gives accurate, contextual answers instead of hallucinating. We handle prompt engineering, tool use, vector databases, and deployment.
On-device and private AI
Not everything should go to the cloud. We build on-device AI features using Gemini Nano, CoreML, and local LLMs for privacy-sensitive use cases. Hybrid architecture: on-device for speed and privacy, cloud for heavy computation.
AI consulting — where AI adds real value
We help businesses evaluate where AI makes sense and where it does not. Our AI consulting covers: which AI features to build, build-vs-buy decisions, LLM selection, cost projections, and architecture planning. We follow up with implementation.

FAQ
Frequently asked questions
- What kind of AI agents do you build?
- Customer support agents, sales agents, HR agents, finance agents, and custom workflow agents. Each includes tool use, memory, and human-in-the-loop oversight.
- What is RAG and do I need it?
- RAG (retrieval-augmented generation) connects an LLM to your data so it can give accurate answers based on your documents, databases, or knowledge base. If your AI needs to reference specific information rather than general knowledge, you need RAG.
- Can you add AI to my existing app?
- Yes. We integrate AI features into existing mobile apps, web apps, and SaaS products without rebuilding. AI chatbot, smart search, recommendations, automation — we add what makes sense for your product.
- How much does AI agent development cost?
- It depends on complexity. Simple chatbot integration starts from $1,500/month. Full agentic workflows with RAG and tool use start from $3,000/month. Contact us for a plan.
- Do you offer AI consulting without development?
- Yes. We help you evaluate AI opportunities, choose the right approach, estimate costs, and plan the architecture. You can then build with us or use the plan with another team.
- What is the difference between an AI agent and a chatbot?
- A chatbot responds to messages. An AI agent takes actions — it can search your data, process transactions, send emails, and make decisions with human oversight. Agents work autonomously; chatbots only react to questions.
- Does my AI need to connect to my company data?
- If your AI needs to answer questions based on your documents, databases, or knowledge base, yes — we connect it to your data so answers are accurate and specific to your business, not generic.
- How do you stop AI from giving wrong answers?
- We connect the AI to your real data so it references facts instead of guessing. We add safety checks, human review for important actions, and audit trails so you can see what the AI did and why.
- Can AI agents connect to Slack, CRM, or internal tools?
- Yes. We connect AI agents to Slack, HubSpot, Salesforce, Google Workspace, Notion, and your internal systems. The agent works inside your existing tools — no need to change how your team operates.
- Is it safe to hire you for AI work?
- Yes. We work through Upwork with escrow payment protection — you pay only when you approve the work. See our reviews and portfolio at teamzlab.com/portfolio.
