I will build a custom ai chatbot, rag chatbot, and ai search using openai or gemini


About this gig
Most AI chatbots give generic answers because they aren't trained on your business data. I build custom AI chatbots, RAG chatbots, AI search, and conversational AI solutions using OpenAI or Google Gemini that answer from your documents, PDFs, FAQs, websites, or databases with accurate, context-aware responses.
What you'll get:
- Custom AI chatbot or AI assistant
- RAG (Retrieval Augmented Generation) implementation
- Knowledge base chatbot trained on your data
- AI search with semantic search and embeddings
- React, Next.js, and Node.js application
- Secure authentication and API integration
- Chat history with MongoDB, PostgreSQL, or Supabase
- Embeddable website chatbot or standalone dashboard
- Full source code and deployment support
I'm a full-stack developer with 5+ years of experience building scalable AI applications using React, Next.js, Node.js, OpenAI, Gemini, and vector databases.
Message me with your use case, such as customer support, document Q&A, AI search, or an internal knowledge base, and I'll recommend the best solution.

FAQ
Can the chatbot answer from my own documents, not just general knowledge?
Yes, in the Standard and Premium packages I set up retrieval so it answers from your documents, FAQs, or database instead of only general AI knowledge.
Which AI model do you use, OpenAI or Gemini?
Either, depending on your budget and use case. Message me and I will recommend the best fit before you order.
Will I own the code and API keys?
Yes, you get full source code and stay in control of your own API keys, so you are never dependent on me to keep it running.
What ongoing costs should I expect after delivery?
You pay OpenAI or Gemini directly for API usage. I will give you a cost estimate based on your expected traffic before we start.
Can this take actions, not just chat?
Yes, that is the AI agent tier, it can book, update a database, or send notifications, not only answer questions.
