As answered by people managing DevFinanceTools and ATS First.
ATS First's answer:
Most resume tools score a resume in isolation and hand you a number. ATS First scores it against a specific job description and then shows the exact keywords the ATS is looking for and your resume is missing — so the fix is a concrete edit, not a vague grade.
It's also the whole loop in one place: check the resume, rebuild it in an ATS-safe template, write the matching cover letter, then run a voice mock interview for that same role and get scored feedback on your answers. Most competitors do one of those four.
And it isn't a subscription. Pro is a one-time, time-limited pass (7-day, 1-month, 3-month) with no auto-renewal — you buy it for the job search, it ends by itself.
ATS First's answer:
ATS First's answer:
Job seekers applying online who get filtered out before a human sees the resume — mid-career professionals switching roles, freshers and recent graduates writing a first resume, and career changers who need to re-target their experience for a new function. Strongest in India, where the free Word formats, biodata and CTC/notice-period tools are built for local hiring norms, with a growing global user base paying in USD.
A second, smaller audience is recruiters and small hiring teams using the bulk resume screening, boolean search builder, JD generator and interview scorecard tools.
ATS First's answer:
ATS First started from a simple, common frustration: qualified people sending out dozens of applications and hearing nothing, because an Applicant Tracking System filtered the resume out before any human read it. The advice online was generic — "use keywords" — with no way to know which keywords, for which job.
So the first thing built was the piece that was missing: score a resume against one specific job description and name the exact terms it's missing. Everything since has followed the same rule — every feature has to change what the user does next, not just report a number. That's how the ATS-safe builder, the cover letter tools and the AI interview coach were added.
The pricing follows from the same idea. A job search is a season, not a forever subscription, so Pro is sold as a one-time pass that expires on its own.
