Cover Letter Generator LLM

View source code on GitHub

Introduction

Cover Letter Generator App was created as part of the interview process at ALMA (https://www.tryalma.ai/). The project took approximately 4-5 hours to complete, with around 3 hours dedicated to creating backend and UI, and an additional 1-2 hours for fine-tuning the prompt to optimize results.

LLM Powered

The LLM used is gpt-3.5-turbo for its cost-effectiveness and impressive capabilities at the given price range.
Local models were avoided due to a lack of available compute resources. However, the design through LangChain allows for easy switching to alternative models. The repo contains two main prompts, each designed with detailed instructions focusing on a different style of cover letter. These prompts can easily be modified or expanded to include additional styles.

Steps

1. Upload Resume:
   • Allows the user to upload a resume in PDF format. The resume is then converted to text using the pypdf2 library.
2. Input Job Listing:
   • Allows the user to input a job listing URL or text. A simple LLM based scraper is used to extract the relevant job description and company information from the URL.
     • Note: For websites which are hard to scrape, please use the text option to enter the job description manually.
3. Style Selector:
   • Allows the user to select a style of cover letter, determining which prompt will be used to generate the cover letter.
     • The Classic style is designed to be a more traditional cover letter with a suitable length and tone.
     • The Modern style is designed to be a more concise cover letter with a more casual tone.
4. Generate Cover Letter:
   • Generates a cover letter based on the selected style and the provided resume and job listing. The generated cover letter is displayed in the UI and can be easily copied to the clipboard.
