What you get with this Offer
Most businesses are still using generic chatbots that frustrate customers with scripted responses that don't actually solve problems. Claude AI changes that entirely, it understands context, handles complex conversations naturally and can be trained on your specific business knowledge to give responses that feel genuinely intelligent rather than automated.
I will design and build a fully custom AI-powered chatbot or application using the Claude API, integrated directly into your website, web app or mobile app. Whether you need a customer support assistant that handles enquiries without human intervention, a sales assistant that qualifies leads and answers product questions, an internal knowledge base tool that lets your team query company documents instantly, or a custom AI-powered feature built into your existing platform, I will build it around your specific use case.
The build will include Claude API integration with a custom system prompt tailored to your business, a clean conversational interface designed to match your brand, conversation history and context management so the AI remembers what was discussed within a session, and an admin panel where you can update the AI knowledge base and monitor conversations. The system will be built to handle high volumes of simultaneous users without performance degradation.
I work with the full Anthropic Claude API including Claude Sonnet and Opus models, selecting the right model for your use case based on the complexity of responses required and your budget for API usage. I will also advise you on expected API costs based on your anticipated usage volume so there are no surprises after launch.
Built using React and Node.js with secure API key management so your Claude credentials are never exposed on the frontend. The architecture is clean, documented and easy to maintain or expand after handover.
On delivery you will receive the complete tested integration, full source code, documentation and a walkthrough so you can update the AI knowledge base and monitor performance independently.

What the Freelancer needs to start the work
To get started I need to know what problem you want the AI to solve for your business, what platform you need it integrated into, any documents or knowledge base content you want the AI trained on, your brand colours and any design preferences, and your expected number of daily users so I can advise on the right Claude model and API cost structure.
