🚀 Cover Letter Generator Chrome Extension

This Chrome extension automates the process of generating a customized cover letter using OpenAI's API. It extracts job descriptions from webpages, generates a tailored cover letter, converts it into a PDF, and automatically attaches it to the file input field on the job application page.

🔥 This is similar to what Simplify Premium offers, but with our extension, you only pay for what you use through your own OpenAI account.

💰 No extra charges—we don’t make any money from this. Instead, you provide your own API key, and the extension generates cover letters at cost.

📌 For reference: Each cover letter costs around 1-2 cents to generate, depending on length and model usage.

🔥 ALSO, THIS ONLY WORKS ON GREENHOUSE APPLICATIONS RIGHT NOW. (🚧 We're working on adding support for Lever and Workday!)

⭐ Please star the repo if you like it and make a PR if you want to contribute! We're constantly updating this, so keep cloning it.

🛠 Troubleshooting

⚠️ API Issues

• Ensure your API key is correctly entered in the extension popup.
• Make sure your API key is active and has sufficient access to the OpenAI API.

❌ Job Description Not Found

• The script looks for a job description inside .job__description.body. If your target job board uses a different class name, update the selector in contentScript.js accordingly.

📂 File Attachment Not Working

• Ensure the job application page has an input field with the ID #cover_letter.
• If the file input field has a different ID, update contentScript.js to match the correct selector.

⚠️ Notes

• 💰 Be mindful of OpenAI API usage limits to avoid unexpected costs.
