Looking for a dev to add an AI feature to my existing app

We've got an online store running on Next.js (App Router), React, and Tailwind, and we'd love to add a little AI chatbot to help our customers out. Nothing crazy — our site already works great, we just want a smart assistant that can answer questions and point people in the right direction. Here's what we're picturing it doing: - Answering the usual stuff — shipping, returns, sizing — from a knowledge base we'll hand you - Helping shoppers find the right product category when they're not sure where to look - Politely passing them off to our support email when it's stumped Since our store is already live and built, this is really just a clean integration — you won't be building anything from scratch. We've got the existing API and design system, so the chatbot just needs to blend in nicely with what we already have. A few details: - Budget: $150–$300, fixed price - Timeline: about 3 days If this sounds like your kind of project, just tell us two quick things in your proposal: 1. Which AI SDK you'd reach for, and why (one line is fine) 2. Anything you'd want to know before diving in
