Questions & Answers

As answered by people managing Codédex and ATS First.

What makes your product unique?

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.

Why should a person choose your product over its competitors?

ATS First's answer:

  • Scoring is job-description-specific, with a missing-keyword gap report, not a generic resume grade.
  • No subscription and no auto-renewal. A 7-day pass is $5 and simply expires — you're never billed again by surprise.
  • The free tier is real, not a paywalled preview: 3 analyses a month, a saved resume, a cover letter, and PDF export without a card.
  • One product covers resume check, resume builder, cover letters and AI voice mock interviews, so you aren't paying three vendors.
  • Exports are genuinely ATS-safe (PDF and DOCX), not design-heavy templates that parse badly.
  • India-first pricing in INR alongside USD, plus content built for the Indian market (biodata formats, fresher resume formats, notice-period and CTC calculators) that global tools ignore.
  • Dozens of free tools and guides with no signup — JD keyword extractor, STAR answer builder, interview question banks by role and by company.

How would you describe the primary audience of your product?

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.

What's the story behind your product?

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.

Which are the primary technologies used for building your product?

ATS First's answer:

  • Next.js 15 (App Router) with React 19 and TypeScript, deployed on Vercel
  • Tailwind CSS 4
  • Firebase — Authentication, Firestore, Cloud Functions, App Check
  • Google Gemini on Vertex AI for resume analysis, generation and interview scoring
  • Google Cloud Text-to-Speech for the voice interview coach
  • Razorpay (INR) and Dodo Payments (USD) for checkout
