# YC idea matcher

![Screenshot of the app UI](ui.png)

This project allows you Submit your idea and get a list of similar ideas that YCombinator has invested in before.

The project is built using the following technologies:

- [Neon](https://neon.tech): Serverless Postgres

- [pgvector](https://github.com/pgvector/pgvector): open-source Postgres extension for vector storage and similarity search

- [Neon Serverless Driver](https://github.com/neondatabase/serverless)

- [Next.js](https://nextjs.org): Fullstack framework for React

- [Vercel](https://vercel.com): deployment platform

- [OpenAI API](https://openai.com): generating vector embeddings

- [TailwindCSS](https://tailwindcss.com): Utility-first CSS framework

- [Upstash Redis](https://upstash.com): serverless Redis for rate limiting

- [Zod](https://zod.dev): TypeScript-first schema validation

- [React Query](https://react-query.tanstack.com): data fetching and caching library

- [Vaul](https://vaul.emilkowal.ski/): Drawer component for React.

## How the app works

You will find a script called `generate-embeddings.ts` located in the root directory of this project. After running `npm run generate-embeddings`, the script does the following:

1. It creates the database schema and installs the `pgvector` extension

2. It goes through the YCombinator API 'https://api.ycombinator.com/v0.1/companies?page=1' and gets all the companies

3. For each company it generates embeddings using the long description and then stores the company data in the database.

  

> Some companies don't have a long description, so we needed to manually remove those from the database by running `delete from companies WHERE embedding = ARRAY[]::real[];`

The app itself is a Next.js app with an API route located at `/api/idea`. Whenever a user submits an idea, the following happens:

1. The idea is sent to the OpenAI API to generate an embedding

2. We then use pgvector to retrieve the top 3 most similar ideas
