Everything you need to get the most out of AI Cover Letter Generator

🚀 Getting Started

Quick Start: The extension is super easy to set up. You'll need an API key from either OpenAI or Claude (or both for maximum flexibility).

Step-by-Step Setup

Install the Extension

Add it to Chrome from the Chrome Web Store or load it manually in developer mode.

Get Your API Key

Choose your AI provider:

Configure the Extension

Click the extension icon → Settings gear → Add your API key → Test connection

Add Your Info

Upload your resume and fill in your contact details. This makes the cover letters personalized.

Start Generating!

Go to any job site, find a job you like, click the extension icon, and hit "Generate Cover Letter"

Pro Tip: Set up both OpenAI and Claude APIs. If one is down or you hit rate limits, you can instantly switch to the other!

❓ Frequently Asked Questions

How much does this cost? +

The extension is completely free! You only pay for the AI API usage, which is typically:

  • OpenAI GPT-4o-mini: ~$0.01-0.03 per cover letter
  • OpenAI GPT-4o: ~$0.05-0.15 per cover letter
  • Claude 3.5 Sonnet: ~$0.03-0.08 per cover letter
  • Claude 3 Haiku: ~$0.01-0.03 per cover letter

Way cheaper than subscription services that charge $10-30/month!

Which job sites does it work on? +

Pretty much everywhere! I've tested it on:

  • LinkedIn Jobs
  • Indeed
  • Glassdoor
  • Monster
  • ZipRecruiter
  • AngelList/Wellfound
  • Company career pages
  • University job boards
  • Government job sites

If it has a job description on the page, the extension can probably read it!

Is my data secure? +

Absolutely! Here's how your data is handled:

  • API Keys: Stored locally in Chrome's encrypted storage
  • Personal Info: Never leaves your browser except for AI API calls
  • Job Data: Processed temporarily, not stored permanently
  • No Tracking: Zero analytics, no data collection
  • Open Source: You can see exactly what the code does

I built this for myself first - privacy was a top priority.

Can I customize the writing style? +

Yes! The extension offers several options:

  • Writing Tone: Professional, Enthusiastic, Concise, or Friendly
  • Length: Short, Medium, or Detailed
  • Custom Instructions: Add your own guidance in settings
  • Multiple Models: Different AI models have different writing styles

You can also regenerate letters with different settings until you find one you love.

What if the cover letter is terrible? +

I won't lie - sometimes the AI has an off day. Here's what to do:

  • Try a different model: Switch from GPT-4o-mini to GPT-4o or Claude
  • Update your resume: More detailed resume = better letters
  • Add custom instructions: Tell the AI what to emphasize
  • Edit the output: The generated text is fully editable
  • Regenerate: Hit the button again for a fresh attempt

In my experience, GPT-4o and Claude 3.5 Sonnet produce the best results.

Can I use this for other types of writing? +

Technically yes, but it's really optimized for cover letters. The extension:

  • Looks specifically for job descriptions
  • Uses prompts designed for cover letter writing
  • Includes resume context automatically
  • Formats output as business letters

If you need other types of AI writing, I'd recommend using ChatGPT or Claude directly.

🔧 Troubleshooting

Extension Not Detecting Jobs

Most Common Issue: This usually happens on dynamic job sites that load content after the page loads.

Try this:

  • Refresh the page after it fully loads
  • Wait a few seconds, then click the extension icon
  • Use the "🔄 Force Re-detect" button in the popup
  • Make sure you're on the actual job description page, not search results

API Errors

Error: Invalid API key Error: Rate limit exceeded Error: Insufficient quota

Solutions:

  • Invalid API key: Double-check you copied the key correctly
  • Rate limits: Wait a few minutes or switch to the other AI provider
  • Insufficient quota: Add billing to your OpenAI/Claude account

Generated Letters Are Generic

This usually means your resume isn't detailed enough. Try:

  • Adding specific achievements with numbers
  • Including relevant skills and technologies
  • Adding custom instructions about what to emphasize
  • Using GPT-4o or Claude 3.5 Sonnet for higher quality

PDF Download Not Working

This is usually a browser popup blocker issue:

  • Allow popups for the job site domain
  • Try right-clicking the PDF button and "Save link as"
  • Copy the text and paste into Google Docs, then export as PDF
Still having issues? Check the browser console (F12 → Console) for error messages, then contact support with the details.
