# Sarcastic Twitter Bot


### This bot reluctantly answer with sarcastic responses. Uses OpenAI's [GPT-3 API](https://beta.openai.com/playground/p/default-marv-sarcastic-chat) to generate the comments. Hosted on [Heroku](https://www.heroku.com/), and uses [offcial Twitter SDK](https://github.com/twitterdev/twitter-api-typescript-sdk) to interact with Twitter.

**Note:** Right now, the bot is not deployed because Heroku removed its free tier and I can't find any other alternative that supports running a bot in the background. If you find one, connect me on Twitter [`roh1tkumar`](https://www.twitter.com/roh1tkumar)

**Note:** mention `@bot_witty` in a tweet or under a tweet like below example.

*I have used another library to post the tweet because the official Twitter SDK was not working for me, got some error which I was not able to resolve, hence I used [twit](https://www.npmjs.com/package/twit). If you are able to resolve the issue, please feel free to open a PR.*
