How it works

Three steps from CV to interview.

  1. The TuneCV My Resumes screen: a saved CV card with the upload and create-from-template actions.
    01

    Upload your CV, paste the job

    PDF, DOCX or TXT in, plus the job description you are applying to.

    • PDF, DOCX and TXT, parsed into one structure
    • The job description goes in the same screen
    • One CV, a version per role
  2. The TuneCV Analytics screen: total applications, interview rate, offer rate and average response time.
    02

    Fix what the ATS reads

    A score for keyword coverage, action verbs and quantified results, with a rewrite per section.

    • Keyword coverage, action verbs, quantified results
    • A rewrite per section, not one blob of text
    • The score is recomputed after every edit
  3. The TuneCV Job Applications screen: a Kanban board with the total application count and the add-application action.
    03

    Apply and track it

    Generate the cover letter, prepare for the interview, and move the application across the board.

    • The cover letter is written from the same job text
    • Interview preparation from the same posting
    • Applications move across the board as they progress

Who it is for

Built for three kinds of team.

01

Active job seekers

You apply to many roles a month and rewrite the same CV for each one.

02

Career switchers

Your experience is real, but it is phrased for the job you are leaving, not the one you want.

03

Anyone behind an ATS portal

Your application is read by software before a person, and you want to know what it sees.

Capabilities

What it does.

01

Multi-format parsing

PDF, DOCX, TXT with intelligent text extraction. Handles scanned PDFs, multi-column layouts, and tables.

02

ATS scoring & keyword analysis

Automated scoring against any job description. Identifies missing keywords, weak sections, and phrasing that hurts ATS ranking.

03

GPT-4 resume improvements

AI-suggested rewrites per section — quantified achievements, action verbs, technical-skills framing. Reviewable before accept.

04

Resume builder with templates

Drag-and-drop editor with professional templates and PDF export. Version history with rollback and ATS-score tracking.

05

Cover letters & interview prep

Personalized cover letters per job application. AI mock interviewer with a question bank and feedback.

06

Application tracker

Kanban-style job application management with status workflow. In-app job search with salary, remote, and experience filters.

Case study

How this product came about, and where it actually stands.

Problem. Job seekers rewrite their CV from scratch for every application. Format friction eats hours. ATS systems reject well-qualified candidates for phrasing issues, not skill gaps.

Approach. Multi-format parser (PDF / DOCX / TXT) with intelligent text extraction. ATS scoring against any job description. GPT-4-driven per-section rewrite suggestions with measurable ROI (keyword coverage, action verbs, quantified achievements). Kanban application tracker. Polar.sh + Stripe billing integration.

Status as of October 2026. In development, with no public URL yet. Backend feature-complete since 11 July 2026 (390+ tests green, webhook handling live, feature gating done). Frontend checkout and dashboard functional; AI-feature UIs (rewrite-suggestion panel, ATS score display) in flight. Billing is migrating from Stripe to Polar: the implementation is done, go-live and instrumentation are still to come.
