AI ATS Checker

AI Keyword Matching

This core feature acts like a smart keyword detective for your resume. It doesn't just list words; it uses advanced AI to understand context and instantly match your skills and experience with the keywords and phrases found in your target job description. It identifies gaps and suggests the most relevant terms to include, ensuring your resume speaks the same language as the ATS and the hiring manager, dramatically improving your visibility.

AI Formatting Check

A visually perfect resume can still contain hidden formatting traps that cause ATS systems to misread or reject it. Our AI Formatting Check meticulously scans your document for these common blockers, such as complex tables, headers/footers, unusual fonts, or graphic elements. It provides clear guidance on how to fix these issues, ensuring your content is parsed correctly and nothing valuable gets lost in the digital shuffle.

Job Match Score

Use Cases

AI ATS Checker

Tailoring Your Resume for a Specific Job Posting

You've found the perfect job listing. Instead of sending the same generic resume, paste the job description into our tool alongside your resume. The AI will provide specific recommendations on which keywords to integrate, which skills to highlight, and how to phrase your experience to align perfectly with that particular role, turning a good application into a standout one.

Overcoming a Lack of Interview Callbacks

If you're applying to jobs but not getting interviews, your resume might be getting filtered out by ATS software. Use the AI ATS Checker to diagnose the problem. The formatting check can reveal technical issues, while the keyword analysis can show if your resume lacks the critical terminology recruiters are searching for, helping you break through the digital barrier.

Preparing a Resume After a Career Gap or Pivot

When changing industries or returning to the workforce, it can be challenging to frame your experience effectively. Our tool helps you translate your skills into the right keywords for your new target field. By analyzing job descriptions in your desired industry, it provides insights on which transferable skills to emphasize and the specific jargon to adopt.

Ensuring a Clean, ATS-Friendly Format

You might have a beautifully designed resume with columns, icons, and creative layouts. Unfortunately, these often confuse ATS systems. Before applying to any major company, run your resume through our Formatting Check. It will identify elements that could cause parsing errors and guide you toward a cleaner, more compatible format that preserves your content's integrity.

Stellar Staff

Scaling Operations for Small Businesses

A small business owner wearing too many hats can hire a VA to handle customer service, appointment scheduling, email management, and lead qualification. For example, Carlos helped a local law firm reduce missed calls by 90%, ensuring no opportunity was lost and operations ran professionally.

Boosting Sales and Marketing Efforts

Entrepreneurs and marketing managers can delegate tasks like social media management, email campaign execution, and lead generation to a skilled VA. Emily helped a boutique bakery triple its online orders in just two months by effectively managing and optimizing its digital sales channels.

Streamlining Administrative and Executive Tasks

Executives and founders drowning in administrative work can offload calendar management, travel booking, data entry, and report preparation. This frees up dozens of hours per week to focus on high-level strategy, business development, and core revenue-generating activities.

Managing Specialized Projects and Recruitment

Businesses needing support for specific projects, like scaling a construction company's operations or conducting high-volume recruitment, can find VAs with niche expertise. Marisol, for instance, expertly handles interviewing up to 30 candidates a day for her client, streamlining the entire hiring pipeline.
