💡 Tips & Tricks

- Minimize with the
−button — the 🔍 toggle stays visible - If LinkedIn updates its layout, use Manual Mode as fallback
- The cover letter is written in the job's language (Arabic or English) by default
- For the best results, keep your profile text detailed and up to date
🔒 Privacy & Security
- Your API key is stored locally in the browser extension storage — never sent anywhere except Google's Gemini API
- Your profile data stays local — only sent to Gemini when you click Analyze
- No analytics, no tracking, no external servers
- The extension only runs on
linkedin.com/jobs/*pages
❓ Troubleshooting
| Problem | Solution |
|---|---|
| Panel doesn't appear | Wait 2-3 seconds after page loads, then scroll the page slightly |
| Job not detected | Use Manual Mode — paste the job description |
| "Daily limit reached" | Wait until midnight Pacific Time (PT) for quota reset |
| "Invalid API key" | Re-check the key in settings and click Test |
| Analysis is wrong | Edit your profile in settings to be more accurate |
| Panel overlaps content | Drag it to a different position |

🔄 Updating
When LinkedIn changes its layout (happens 2-4x per year):
- The DOM selectors in
content.js→extractJobData()may need updating - Use browser DevTools (F12) on a job page to find new selectors
- Manual Mode always works as fallback
