Frequently Asked Questions

What is an ATS resume checker?

An ATS resume checker scores a resume the way Applicant Tracking System software does: checking keyword match against a job description, section completeness (contact info, experience, education, skills), formatting issues that can break parsing, and content quality like quantified, action-verb-led bullet points. AI Resume Builder's ATS checker runs this analysis instantly and lists concrete fixes, both for resumes built in the tool and existing resumes uploaded as PDF, DOCX, or TXT.

Is AI Resume Builder free to use?

Yes. AI Resume Builder is free to use, with no signup required to build a resume, run an ATS check, or generate a cover letter.

How does the AI improve my ATS score?

After an ATS scan, the built-in AI assistant can rewrite the professional summary and strengthen weak bullet points to close specific keyword and content gaps, aiming for a score of 80 or higher. It never invents jobs, dates, or contact details it doesn't have - if it can't safely reach the target score without fabricating information, it says so and lists what's still missing.

Can I download my resume as a PDF or Word document?

Yes. Every resume and cover letter can be downloaded as a real, selectable-text PDF (via the browser's native print-to-PDF, not a flattened image) or as a Word (.docx) file.

Is my resume data private?

By default, resumes are stored locally in your browser and are never uploaded to a server - the resume builder, ATS scoring, and cover letter generation all run client-side.
