AI Chatbot for Next.js
Ship a production RAG chatbot in your Next.js app. Embed the widget with next/script or call the REST API directly for full control.
Next.js developers want a chatbot that respects performance budgets and does not require standing up a whole RAG pipeline. ChatbotsHub handles embeddings, vector search, and generation for you, and exposes both a drop-in widget and a REST API.
Add the widget with the next/script component for a zero-effort launch, or call the API from a server action or route handler to build a fully custom chat UI. Either way, you skip the infrastructure and keep the developer experience.
Why use an AI chatbot for Next.js?
Drop-in or fully custom
Use the widget via next/script, or the REST API to build your own chat interface with your components.
No RAG plumbing
Embeddings, chunking, vector search, and the LLM call are handled — you just send a question.
Performance-first
Load the widget with the afterInteractive strategy so it never blocks hydration or LCP.
Own your knowledge base
Train on your docs and update content without redeploying your app.

Frequently asked questions
How do I add the chatbot to a Next.js app?
Use the next/script component in your root layout with the widget URL and the afterInteractive strategy, or call the ChatbotsHub REST API from a route handler for a custom chat UI.
Is there an API instead of the widget?
Yes. ChatbotsHub exposes a REST API with an API key so you can build a fully custom chat experience with your own React components.
Will the widget hurt my Core Web Vitals?
No. Loading it with the afterInteractive strategy defers it until after hydration, so it does not block LCP or interactivity.
Do I need to build my own RAG pipeline?
No. ChatbotsHub handles embeddings, vector search, and generation, so you only send the user question and render the answer.
