I will build a rag chatbot for your documents or website


Level 2
About this gig
Stop searching manually through PDFs, SOPs, manuals, policies and website pages.
I build custom RAG chatbots that answer questions using your documents, website content or internal knowledge base and provide source citations so users can verify where the information came from.
This service is ideal for:
- Customer-support knowledge bases
- Internal employee assistants
- SOP and policy search
- Product-documentation chatbots
- PDF and document question answering
- Research and training portals
Your chatbot can include:
- PDF, DOCX, TXT and website ingestion
- Source-grounded answers with citations
- Vector search and advanced retrieval
- A branded web interface or embeddable widget
- Authentication and admin document uploads
- API integration and private deployment
I work with OpenAI, Claude, Gemini, Llama and Ollama using LangChain or LlamaIndex, FastAPI, React and vector databases such as Pinecone, Qdrant, Chroma or FAISS.
Please message me before ordering with your data sources, approximate document volume, users, privacy needs and preferred deployment.

FAQ
What types of data can the chatbot use?
I can work with PDFs, DOCX files, TXT files, Markdown, website pages, FAQs, SOPs, manuals, policies and selected database or API content. Please share a sample before ordering.
Will the chatbot show source citations?
Yes. The chatbot can display the source document, page, section or retrieved passage depending on the data format and package.
Can you embed the chatbot on my website?
Yes. Standard and Premium can include a website widget, branded web interface or API that your development team can integrate.
Will you train or fine-tune an AI model on my documents?
This gig primarily uses Retrieval-Augmented Generation. Your documents are indexed and retrieved when a user asks a question. Model fine-tuning is a separate service and is usually not required for document question answering.
Can the chatbot run privately or locally?
Yes. I can build private-cloud or local Ollama-based setups when the required infrastructure and model capabilities fit your use case. Private deployment should be discussed before ordering.
Which AI model will you use?
I can work with OpenAI, Claude, Gemini, Llama, DeepSeek or Ollama. I will recommend a model based on accuracy requirements, privacy, latency and operating cost.
Will I receive the source code?
Yes. Source code is included in all packages. API keys, hosting accounts and paid third-party usage costs remain the buyer's responsibility.
Can I add or update documents later?
Yes. Standard can include a basic update process, while Premium can include an admin document-upload and re-indexing workflow.
Can you guarantee that the chatbot never gives a wrong answer?
No responsible RAG system can guarantee zero errors. I use retrieval, citations, prompt controls and evaluation to reduce unsupported answers and make responses easier to verify.
What do you need before starting?
I need your use case, target users, sample documents or website URL, approximate data volume, required integrations, privacy requirements, preferred hosting and expected chatbot behavior.
