Blank repo to live product

Pay-per-job

The product

Upload a resume. Paste a job posting. Get an unrejectable version back.

PrimeResume.ai reads the resume you already have, scores it against the job you're chasing, and rewrites the weak lines in language that passes Applicant Tracking Systems. Every change is shown in a line-by-line diff, with a separate fact-check pass so nothing gets invented. Export to DOCX or PDF. Pay per job, never a subscription.

Product in action

What it actually looks like. Three moments from the live product.

Screenshots from PrimeResume.ai itself: the July 2026 release, captured live and embedded here so this reads as a real case study, not an abstraction.

PrimeResume.ai intake step: a 'Tell us about the job' form with job title and description fields, step indicators 1 through 4, and a skeleton resume preview alongside.

Intake · Step 1 of 4

Paste the job description

The flow starts with the posting, not the resume, so every downstream suggestion is grounded in the role the candidate is actually chasing.

PrimeResume.ai analysis view: a green 90 percent ring labeled 'Strong match', overall quality 90.2 and ATS compatibility 90 sub-scores, and two missing keywords flagged in red, Google Ads and Paid acquisition.

Analysis · Step 3 of 4

Score, gap, report

Named score, named keyword gap, section-by-section breakdown. Free, before signup. This is the money shot: the moment a generic 'good resume' becomes a specific, fixable one.

PrimeResume.ai pricing: 'Pay per job. No subscriptions. No surprises.' above two cards, a $19 Application Package marked Most popular and a $49 Serious Search bundle, each listing the full application package contents.

Pricing · Pay per job

One credit, one application, done

$19 buys everything for one job (resume, cover letter, LinkedIn rewrite, interview prep) with no subscription anywhere. Transparent fixed pricing, the same conviction we run at IB Digital.

The problem

Over 90% of enterprise hiring runs through an ATS. Most resumes never reach a human.

Applicant Tracking Systems auto-rank candidates by keyword density, section structure, and formatting conventions. The good resumes that don't match the posting get filtered out before a recruiter scrolls past the first screen.

The fix (rewriting each resume for each role) is tedious enough that most candidates don't do it. And the generic AI writers that promise to do it for them invent experience candidates don't have, which shows up in the interview and ends the conversation.

90%+ of enterprise hiring flows through Workday, Greenhouse, Lever, Taleo, iCIMS: pick a keyword gap, get filtered.

Manual tailoring takes 30–60 minutes per role; most candidates apply to dozens.

Generic AI rewriters fabricate skills; a recruiter spots it the moment they ask a follow-up question.

What we shipped

Six capabilities, one end-to-end product.

None of these shipped as a demo. Each is live, paying, and serving real candidates today.

Read any resume

Drop in a PDF from any template or decade. Structured data (name, history, skills, achievements) comes out the other side without a manual form.

Score against the listing

Paste a job posting and see the ATS match score, the keywords you already have, and the exact ones you're missing for that role.

Rewrite, every change shown

Bullet-by-bullet rewrites grounded in the candidate's real experience, approved through a line-by-line diff. A separate fact-check pass verifies nothing was invented — or the credit is refunded.

Export anywhere

DOCX for Word and Google Docs, PDF for portals, editable source for final polish. ATS-safe formatting by default.

Pay-per-job commerce

One credit = one job = the full application package: tailored resume, cover letter, LinkedIn rewrite, interview prep. $19 per application, down to $12.25 in bundles. No subscription, credits never expire.

A resume library

Auth, cloud storage, and a history of every version the user has generated, so a candidate targeting ten roles keeps ten tailored resumes in one place.

How we shipped it

AI-native from the first commit. Boutique delivery, dramatic compression.

PrimeResume.ai is the clearest demonstration we have of the delivery model IB Digital runs for clients. Pair-programmed with Claude Code as primary IDE. Supported by Cursor where a different tool fit the task. Playwright test coverage authored by the same agents that wrote the features.

At runtime, the AI pipeline itself is multi-model: the right specialized model for parsing, for keyword analysis, and for content generation, routed through a single unified layer so the product can pick the best tool without a rewrite.

And the model keeps proving itself: in July 2026 the product shipped a ground-up rebuild (new design system, new free-check funnel, new pay-per-job pricing) as a single release, built the same AI-native way.

01

Pair-programmed with Claude Code

The same AI-native workflow we bring to every engagement. Principal engineer driving, Claude Code translating intent to diffs, humans owning the call on every architectural choice.

02

AI-authored test coverage

Playwright specs generated alongside the features they exercise. Regressions caught before every release, not discovered by users a week later.

03

Multi-model AI runtime

Specialized models for parsing, analysis, and generation, picked per step and swapped without touching the app. The same routing discipline we deploy on client builds.

The outcome

Weeks to live. In production today.

The feature set that would take a traditional team a full quarter (parse, score, rewrite, export, bill, and host) shipped, paid, and live to real candidates inside a handful of weeks. PrimeResume.ai isn't a side project; it's the proof that the IB Digital delivery model works.
