I will create and integrate an ai chatbot into your website
Muhammad Khan
About this gig
Static websites don't answer customer questions at 2am. An AI chatbot does.
I build and integrate AI-powered chatbots directly into your existing website connected to an LLM (GPT, Mistral, or your provider of choice) and, if needed, your own documents through retrieval-augmented generation (RAG), so the bot answers from your content instead of making things up.
What I build:
- A chat widget integrated into your website's frontend (React or plain HTML/JS)
- Backend API (FastAPI) connecting to your chosen LLM provider
- Optional: RAG setup so the bot answers from your docs, FAQs, or product data
- Optional: conversation memory, custom system prompt matching your brand voice
What I need from you:
- Access to your site/codebase (or a page where the widget will sit)
- Any documents/FAQs the bot should know about
- Your preferred LLM provider, or I'll recommend one based on your budget
I've built production AI systems end-to-end not just wired up a demo API call. I'll tell you upfront if your use case needs RAG (higher accuracy, more setup) or if a simpler prompt-based bot will do I won't oversell you a bigger build than you need.

FAQ
Which LLM provider should I use?
Depends on your budget and use case — I'll recommend one rather than pushing a single provider by default.
Do you guarantee the chatbot won't ever give a wrong answer?
No honest developer can guarantee zero hallucination from an LLM. I build proper grounding and edge-case handling so it fails gracefully instead of making things up confidently.
Do I need RAG, or is a simpler bot enough?
If your bot just needs a consistent tone/persona, Basic or Standard covers it. RAG (Premium) is for when it needs to answer from a large or frequently changing set of documents.
Can you deploy this for me?
Yes — deployment can be included as an add-on if not already covered in your package.
