About this gig
Need an AI chatbot that can answer questions, support customers, or work with your own documents and business data?
I can build a custom AI chatbot or assistant for your website, web app, mobile app, or internal business tool using OpenAI, Claude, Gemini, secure backend APIs, and RAG when needed.
Your chatbot can include a modern chat interface, document uploads, knowledge-base search, conversation history, user authentication, database storage, API integrations, lead capture, support workflows, usage limits, and admin controls.
I can also connect the chatbot with PDFs, website content, FAQs, CRM data, Supabase, PostgreSQL, or other approved data sources.
The chatbot will be designed around a clear use case rather than generic AI responses. Third-party AI, hosting, vector database, and messaging costs are separate.
Main services:
- Custom AI chatbot development
- OpenAI, Claude, and Gemini integration
- RAG chatbot development
- Website and app chatbot integration
- Document and knowledge-base chat
- Customer-support chatbot
- AI assistant development
- Secure backend API integration
Please message me with your chatbot goal, data source, target users, and required integrations before ordering.
