## Description

This project uses Next.js with shadcn/ui for creating a semantic search engine with Langchain. It was created following the tutorial in this article: [Langchain Retrievers Tutorial](https://js.langchain.com/docs/tutorials/retrievers/). The project uses OpenAI as the chat model.

## Video Demonstration

Watch the video below to see an example usage of the app:

## Technologies Used

This project leverages the following technologies:

- **Next.js**: A React framework for server-side rendering and generating static websites.

- **shadcn/ui**: A component library for building user interfaces.

- **Langchain**: A framework for developing applications powered by language models.

- **OpenAI**: Used as the chat model for generating responses.

- **TypeScript**: A typed superset of JavaScript that compiles to plain JavaScript.

- **Tailwind CSS**: A utility-first CSS framework for styling.

- **Vercel**: Hosting platform for deploying the application.

## Getting Started

First, create a `.env.local` file with your API keys by using `.env.local.template` as a template:

```bash

cp .env.local.template .env.local

```

Then, run the development server:

```bash

npm run dev

# or

yarn dev

# or

pnpm dev

# or

bun dev

```

Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.

You can start editing the page by modifying `app/page.tsx`. The page auto-updates as you edit the file.
