I will build a custom rag web app with langchain, openai and react
About this gig
Want to chat with your own documents inside a custom web app?
I build RAG web apps that let users upload PDFs, documents, or web pages, ask questions in plain English, and get answers with source citations.
WHAT YOU GET
Responsive React frontend and Python backend using Django or Flask.
RAG pipeline with LangChain, OpenAI, Claude, or Gemini and a vector database.
Document upload, indexing, and source citations.
Full source code you own.
Standard and Premium include user login, an admin dashboard, and a deployment guide.
IDEAL FOR
Internal knowledge bases, policy and FAQ search, client portals, research tools, and MVPs.
HOW I WORK
1. Share your idea and sample documents. I confirm scope, timeline, and price.
2. I build in milestones so you can review progress.
3. You test the app, I revise within the agreed scope, and provide a deployment guide. Deployment is available as an extra.
NOTES
You pay AI and hosting providers directly. RAG apps can produce inaccurate answers, so I test with your documents and demonstrate the results.
Please message me before ordering.

FAQ
What is a RAG app?
It answers questions from your own documents instead of guessing. It finds the relevant passages first, then writes the answer and shows the source.
Can I upload PDFs, Word files and web pages?
Yes. Tell me the file types before ordering and I will confirm.
Which AI model do you use?
OpenAI, Claude or Gemini, through LangChain, so you can swap models later..
Who pays for AI and hosting costs?
You do, directly to the providers, through your own accounts and API keys.
Can you add RAG to my existing app?
Yes. Message me first and I will confirm the scope and price.
Will answers always be correct?
No system is perfect. I test with your documents, show you the results, and tune retrieval so answers stay grounded in your content.
Do you deploy the app for me?
Standard and Premium include a deployment guide. I can also deploy it for you with the Cloud Deployment extra.
Can you provide the source code?
Yes, full source code is included in every package.
