Stop copying and pasting job descriptions. With Ajusta's Chrome Extension, you can optimize your resume directly from any job posting with a single click. This comprehensive guide walks you through installation, setup, daily usage, and advanced features so you can apply to jobs 10x faster without ever leaving the job board.
The average job seeker spends 30-45 minutes customizing each resume manually. Multiply that by 20-30 applications per week, and you are looking at a part-time job just to apply for jobs. The Ajusta Chrome Extension changes this equation completely by automating the entire optimization workflow -- from extracting the job description to delivering a tailored, ATS-optimized resume -- in under 10 seconds, right from the job posting page.
Whether you are power-applying on LinkedIn, browsing Indeed during lunch, or scanning Glassdoor before bed, this extension transforms every job posting into an instant optimization opportunity. In this guide, we cover everything from basic installation to advanced batch optimization techniques used by our most successful users.

Ready to install?
If you already have an Ajusta account, jump straight to the Chrome Web Store and install the extension. Setup takes under 60 seconds.
Install Chrome ExtensionStep 1: Install the Chrome Extension
Open the Chrome Web Store
Open Google Chrome and navigate to the Chrome Web Store. You can get there by typing chrome.google.com/webstore in your address bar, or by clicking the direct link in your Ajusta dashboard under "Tools".
Search for "Ajusta Resume Optimizer"
Type "Ajusta" in the search bar. Our extension will appear as "Ajusta - AI Resume Optimizer" with the green Ajusta logo. Verify the publisher name matches "ajusta.ai" to ensure you are installing the official extension.
Click "Add to Chrome"
Click the blue "Add to Chrome" button. A confirmation dialog will appear listing the permissions the extension needs. These permissions allow the extension to read job descriptions from web pages and communicate with your Ajusta account.
Confirm Installation
Click "Add Extension" in the confirmation dialog. The Ajusta icon will appear in your Chrome toolbar (top-right area of your browser). If you do not see it, click the puzzle piece icon to find it and pin it to your toolbar for easy access.
Note: The extension is 100% free and included with all Ajusta accounts. Installation takes under 30 seconds and uses less than 2MB of storage.
Step 2: Connect Your Ajusta Account
The extension needs to connect to your Ajusta account to access your resumes and optimization credits. If you do not have an account yet, you can create one during this step and receive 500 free credits instantly.
Click the Ajusta Extension Icon
Click the Ajusta icon in your Chrome toolbar. A popup window will appear showing the extension interface. If this is your first time opening it, you will see a "Sign In" button.
Click "Sign In"
Click "Sign In" to open the authentication flow. A new tab or popup will open asking you to sign in with Google. Use the same Google account you used to create your Ajusta account.
Complete Google Authentication
Select your Google account and authorize the connection. This links your extension to your Ajusta dashboard, syncing your resumes, credits, and application history.
Verify Connection
After authentication, the extension popup will show "Connected" with your name and credit balance displayed. You are now ready to start optimizing directly from job postings.
Step 3: Navigate to a Job Posting
The extension works on any job posting page across the internet. It uses intelligent content detection to automatically identify and extract job descriptions from the page you are viewing. Here are the platforms where it works best:
Officially Supported Sites
- LinkedIn Jobs
- Indeed
- Glassdoor
- AngelList / Wellfound
- Monster
- ZipRecruiter
Also Works On
- Company career pages
- Workday portals
- Greenhouse job boards
- Lever career pages
- University job boards
- Any page with job text
How to tell if the extension detected a job: When you are on a page with a job description, the Ajusta icon in your toolbar will show a small green dot in the bottom-right corner. A gray icon means no job description was detected on the current page.
Step 4: Click the Extension Icon and Optimize
Click the Ajusta Icon
When you see the green dot on the extension icon, click it. The popup will show the detected job title, company name, and a preview of the extracted job description.
Select Your Base Resume
If you have multiple resumes saved in your Ajusta account, choose which one to optimize. The extension will suggest the best match based on the job type, but you can always override this selection.
Choose Your Optimization Mode
Select YOLO (5 seconds, 94% average ATS score) or Classic (30-45 seconds, 96-98% potential). For most applications, YOLO mode delivers excellent results at maximum speed.
Click "Optimize Now"
Hit the button and wait 5 seconds (YOLO) or 30-45 seconds (Classic). The extension will show a progress indicator. When complete, your ATS score and a download button appear directly in the popup.
Before and After: Extension Optimization in Action
Here is what a typical extension optimization looks like. The user was browsing a Senior Data Engineer position on LinkedIn and used the extension to optimize their resume in one click.
Professional Summary
Before (ATS Score: 47%)
"Data professional with experience in databases and analytics. Skilled at solving problems and working with teams."
After (ATS Score: 93%)
"Senior Data Engineer with 6+ years building scalable ETL pipelines processing 2TB+ daily using Apache Spark, Airflow, and AWS (Redshift, Glue, S3). Reduced data processing latency by 67% while maintaining 99.9% uptime for critical analytics dashboards."
Experience Bullet Point
Before (ATS Score: 35%)
"Worked on data projects and helped the team deliver solutions"
After (ATS Score: 91%)
"Architected and deployed real-time streaming data pipeline using Apache Kafka and Spark Streaming, processing 500K events/second for fraud detection system serving 12M active users"
Step 5: Review and Download
Check Your ATS Score
Your new ATS score is displayed prominently in the extension popup. Aim for 90% or higher. If the score is below 85%, consider switching to Classic mode for a deeper optimization pass.
Download Your Resume
Click the download button to get your optimized resume. The file is automatically named with the job title and company for easy organization (e.g., "Resume_SrDataEngineer_Netflix.html").
View Detailed Changes (Optional)
Click "View Details" to open the full comparison view on the Ajusta dashboard. This shows every change highlighted with explanations for why each modification was made.
Submit Your Application
Go back to the job posting and submit your optimized resume. The application is automatically logged in your Ajusta dashboard so you can track where you applied, when, and what score you achieved.
Platform-Specific Tips
LinkedIn Jobs
The extension works best on LinkedIn. It extracts the full job description, required skills, company culture information, and even the "About the Company" section for better optimization context.
Tip: Use "Easy Apply" jobs for the fastest workflow. Optimize with the extension, download, then upload via Easy Apply in under 30 seconds total.
Important: Make sure you click into the individual job posting (not just the search results list) so the extension can extract the full description.
Indeed
Indeed sometimes splits job descriptions across tabs or behind "Show More" buttons. The extension captures all visible sections automatically, but you should click "Show More" before activating the extension to ensure the full description is extracted.
Tip: Check if the company name matches the actual employer. Indeed sometimes shows recruiting agencies, and optimizing for the agency name instead of the end employer can reduce effectiveness.
Glassdoor
Glassdoor includes salary and company review data alongside job postings. The extension uses this additional context for better cultural alignment in your resume optimization.
Tip: Read 2-3 company reviews before optimizing. If reviewers mention specific values (like "innovation" or "customer obsession"), the optimization will naturally incorporate these themes.
Workday Portals
Many Fortune 500 companies use Workday for their career portals. The extension detects Workday job pages and applies Workday-specific optimization rules automatically. For a deep dive into Workday optimization, see our Workday ATS guide.
Tip: Workday portals often require manual form entry. Have your optimized resume open alongside the form so you can copy sections directly into the fields.
Company Career Pages
For direct company career pages (careers.google.com, amazon.jobs, etc.), the extension uses general-purpose job description detection. If it does not detect automatically, you can select the job description text manually and right-click to optimize.
Advanced Features for Power Users
Power User Techniques
Batch Optimization
Open 5-10 job posting tabs, then go through each one and click optimize. Each optimization runs independently, so you can optimize multiple resumes in parallel. Download all of them when done. Users who batch-optimize report applying to 15-20 tailored jobs per hour.
Application Tracking
Every optimization through the extension is automatically logged to your Ajusta dashboard with the job title, company, date, ATS score, and a link to the optimized resume. This creates a complete application history without any manual tracking.
Smart Resume Suggestions
If you have uploaded multiple base resumes (e.g., one for engineering roles, one for management roles), the extension analyzes the job posting and suggests the best base resume to optimize. This ensures each optimization starts from the most relevant foundation.
Right-Click Optimization
On pages where automatic detection does not work, you can select the job description text, right-click, and choose "Optimize with Ajusta" from the context menu. This works on any webpage, email, or even PDF viewer in the browser.
Common Mistakes When Using the Extension
Mistake #1: Optimizing from search results pages
The extension needs the full job description. On search results pages (like LinkedIn's job list), only a snippet is visible. Always click into the individual job posting first, then activate the extension.
Mistake #2: Not expanding collapsed descriptions
Many sites hide the full description behind "Show More" or "Read Full Description" buttons. Click these before using the extension, or you will only get a partial optimization based on the visible snippet.
Mistake #3: Using an outdated base resume
If you have gained new skills or experiences, update your base resume on the Ajusta dashboard before optimizing. The AI can only work with what you provide -- it will not invent experience you do not have.
Mistake #4: Ignoring the ATS score
If your score is below 85%, do not submit blindly. Try Classic mode, check that the full job description was captured, or update your base resume with more relevant skills before re-optimizing.
Mistake #5: Not pinning the extension
If the extension is hidden in Chrome's extension menu, you will forget to use it. Pin it to your toolbar so the green detection dot is always visible when you are browsing jobs.
Troubleshooting Common Issues
Extension icon is gray (no job detected)
The extension has not detected a job description on this page. Try these fixes:
- Make sure you are on the actual job posting page, not a search results page
- Click "Show More" or "View Full Description" to expand hidden content
- Wait for the page to fully load (some sites load content dynamically)
- Try refreshing the page
- If on a non-standard site, use right-click method: select the job text, right-click, choose "Optimize with Ajusta"
Cannot connect my account
Authentication issues can usually be fixed by:
- Allowing pop-ups for ajusta.ai (chrome://settings/content/popups)
- Clearing your browser cache and cookies
- Restarting Chrome completely
- Disabling other extensions temporarily to check for conflicts
- Making sure you are using the same Google account as your Ajusta dashboard
Optimization seems slow or stuck
If optimization takes longer than expected:
- Check your internet connection
- YOLO mode should complete in 5 seconds; Classic takes 30-45 seconds
- Try closing the popup and reopening it
- Switch to YOLO mode if Classic is taking too long
- If the issue persists, try the same optimization from the Ajusta dashboard directly
The extracted job description looks incomplete
Some sites use complex layouts that can interfere with extraction:
- Expand all sections on the page before clicking the extension
- Use the right-click method: manually select the full job description text first
- If on a Workday portal, navigate to the individual job posting (not the list view)
- Copy the job description manually and paste it directly in the Ajusta dashboard as a fallback

Yes, the extension itself is completely free. It uses the same credit system as the Ajusta dashboard. You get 500 free credits when you create your account, and each optimization uses credits from your balance.
Does the extension work on Microsoft Edge?
Yes. Since Edge is Chromium-based, you can install Chrome extensions from the Chrome Web Store. It also works on Brave, Arc, and other Chromium-based browsers.
Does the extension read my browsing data?
No. The extension only activates on job posting pages and only reads the job description content. It does not track your browsing history, read your emails, or access any data outside of job postings.

You need an Ajusta account to use the extension's optimization features. Creating an account is free and takes under 30 seconds with Google Sign-In. You receive 500 credits immediately upon signup.

Can I use the extension on mobile?
Chrome extensions are not supported on mobile browsers. For mobile optimization, use the Ajusta web app at app.ajusta.ai, which works on any mobile browser. Alternatively, use the extension on desktop and submit applications from your phone later.
What happens if the extension cannot detect a job description?
Use the right-click method: select the job description text on the page, right-click, and choose "Optimize with Ajusta." This works on any webpage regardless of its structure. Alternatively, copy the text and use the Ajusta dashboard directly.
