I will build an ai chatbot using llm, langchain, and rag


About this gig
I'll build you a custom AI chatbot that actually understands your business not a generic FAQ bot, but one that pulls real answers from your own documents, data, or knowledge base using RAG (Retrieval-Augmented Generation) and LangChain.
Instead of guessing answers, the chatbot retrieves relevant information from your content first, then generates accurate responses using a leading large language model (such as Gemini or LLaMA).
What I can build:
- Chatbot that answers from your own doc/FAQs/data
- Website or web-app chat integration
- WhatsApp chatbot setup
- Custom knowledge base from your PDFs/docs
- Clean, working deployment ready to use
Good fit if you:
- Want a chatbot with accurate answers from your real content, not generic AI guesses
- Have documents, FAQs, or a knowledge base to turn into an interactive assistant
- Need a support bot to reduce repetitive questions to your team
- Want something built with reliable, modern AI tools (RAG + LangChain)
Why work with me:
I focus on chatbots that are genuinely grounded in your data, not wrapped-up generic responses. I'll always be upfront about what's realistic for your use case and won't oversell something more complex than what it takes to build

FAQ
How is this different from a regular chatbot?
A regular chatbot often gives generic or pre-scripted answers. This one uses RAG, meaning it actually searches your documents/data first, then answers based on what it finds, so responses are grounded in your real content, not guesses.
What kind of documents can it learn from?
PDFs, text files, FAQs, product docs, or similar written content. Send me what you want it to reference, and I'll set it up to pull answers from there.
Which AI model powers the chatbot?
I use leading large language models such as Gemini or LLaMA, depending on what fits your project best for accuracy and cost.
Can it work on WhatsApp or just on a website?
Both are possible. Web chat is included from Basic; WhatsApp/other integration is available from Standard upward.
Will it support multiple languages?
Not guaranteed by default, performance depends on the documents and model used. If you need this, message me first so I can confirm it'll work well for your specific case.
Can it connect to my CRM or database?
Yes, this is included in the Premium package. If you need this and aren't sure which package fits, message me with details first.
Do I get the source code?
Source code is included in Premium, or available separately as an add-on on other packages.
What do you need from me to start?
The documents/data you want the chatbot to use, your preferred platform (web/WhatsApp/), and any branding detals if applicable.
What if my project needs something not listed in the packages?
Message me with the details before ordering. I'd rather scope it accurately than have you order the wrong package.
