I will build a rag ai chatbot and support agent trained on your documents


About this gig
Do your customers keep asking questions your documents already answer?
I build a RAG-based AI support agent that answers strictly from YOUR business documents (FAQs, policies, manuals, product catalogs, PDFs or website content).
How it works:
- You send your documents (PDF, DOCX, TXT or web pages)
- I turn them into a searchable knowledge base (ChromaDB or Pinecone)
- I build a chatbot that finds the right information and answers in plain language
- You get a working chatbot + documented source code
Why it's reliable:
Answers come from your documents, not guesses
If the answer isn't in your documents, the bot says so
Optional source references to verify answers
Built with Python, LangChain, FastAPI and OpenAI GPT
Good fit for:
- Customer support FAQ bots for small businesses and stores
- Internal knowledge assistants (policies, SOPs, manuals)
- Education content (textbooks, course material)
Optional add-ons (n8n): send leads to Google Sheets/CRM, email alerts when the bot can't answer.
Not sure if RAG fits your documents? Message me before ordering with a short description of your business, and I will tell you honestly.

FAQ
What documents can you use?
PDF, DOCX, TXT, and website pages.
Will the bot make up answers?
It is designed to answer only from your documents and say so when it cannot find the answer. No system is 100% perfect, so I test it with your real questions before delivery.
Do I get the source code?
Yes, with setup instructions.
Who pays for OpenAI API usage?
You do, through your own API key. I can help estimate monthly cost.
Can I update the documents later?
Yes, the Standard and Premium packages include a simple way to add or re-upload documents.
Where does the chatbot run, and who pays for hosting?
The chatbot runs on a server. The Premium package includes deployment on your server. With Basic and Standard, you receive the code and setup instructions. Hosting and OpenAI API usage are paid directly by you.
How does the chatbot appear on my website?
Standard and Premium include a website embed: a small code snippet adds a chat icon to the bottom-right corner of your site. Message me your website platform before ordering and I will confirm it is compatible.
Can you integrate the chatbot into my existing website?
Yes. I can provide an embeddable web chat interface or API depending on your package and website setup.
Can the chatbot show the source used for each answer?
Yes. Source references/citations can be included so users can verify where the answer came from.
Can you use my existing OpenAI, Gemini or Pinecone account?
Yes. I can configure the project using your own API credentials and infrastructure.
