I will integrate an ai chatbot or llm into your website or app

About this gig
Most AI chatbots look good in a demo and fall apart with real users. They make up answers, cost more than expected and nobody can see what they are doing.
I build AI features that do real work inside your product.
WHAT I CAN BUILD
A support chatbot that answers from your own documents and data (RAG).
An assistant inside your app that drafts, summarizes or classifies text.
An LLM step inside an existing workflow, connected to your database or API.
HOW I KEEP IT HONEST
The AI answers from your content and says when it does not know, instead of inventing an answer.
Answers are logged, so you can see what the system said and why (Standard and Premium).
Token costs are estimated up front and capped, so there are no surprises on your bill.
I work with the OpenAI, Anthropic Claude and Google Gemini APIs, in TypeScript, Node.js and Python.
BEFORE YOU ORDER
Tell me what you want the AI to do, where it will live and what data it should use. If an LLM is not the right tool for your problem, I will say so.

I build web applications and AI automations end to end: React and TypeScript on the front end, Node and PostgreSQL on the back.
I am finishing my Computer Science degree and have worked in software since 2023, starting in automation and IT support before moving to full-stack.
What I can do: build a web app from scratch, add features to existing code, connect APIs, design databases, or automate a workflow with scripts or an AI agent.
I write typed, tested code and say clearly what is done and what is blocked. Tell me the outcome you need and I will tell you honestly if I am the right fit.
FAQ
Will the chatbot make things up?
Any LLM can. I reduce it by answering only from your content, instructing the bot to say when it does not know, and logging answers so you can review them. I will not promise zero errors, because nobody honestly can.
How much will the AI cost me to run?
You pay the AI provider directly for usage, on your own account. Before building, I estimate the monthly token cost for your expected volume, and I add limits so a spike in usage cannot run up your bill.
Which AI models do you use?
OpenAI, Anthropic Claude or Google Gemini, chosen for your use case, budget and data rules. The integration is written so the model can be swapped later without rebuilding everything.
