About ATSCheck

Official Architecture & Mission (About ToolForge Engine)

Built by job seekers, for job seekers. ATSCheck exists to eliminate the gatekeeping, paywalls, and predatory subscriptions common in career tech.

Why We Built ATSCheck

Reviewing a résumé for a specific role can take time. ATSCheck offers browser-based checks to help you examine wording, sections, and keyword overlap.

Many commercial resume scanners require account creation, recurring credit card subscriptions, or cloud uploads of personal documents just to view basic feedback. With sensitive details like work history, contact numbers, and personal references on every resume, privacy and transparency often become secondary considerations.

ATSCheck is a free résumé review tool. Résumé text is processed in your browser and is not sent to ATSCheck servers; site fonts are loaded from Google Fonts.

In-Browser Processing

Résumé text is extracted and analyzed in your browser using PDF.js and Web APIs. The site loads fonts from Google Fonts, but résumé text is not sent to ATSCheck servers.

No Paywalls, Ever

Résumé checks, keyword comparisons, formatting feedback, and PDF exports are free with no credit card required.

How the checks work

ATSCheck checks résumé text, section labels, keyword overlap, and common formatting patterns in your browser. It does not test or certify results against Workday, Greenhouse, Taleo, Lever, or iCIMS.

The Technology Stack Behind ATSCheck

ATSCheck is engineered as a static, single-page progressive web application built with React, TypeScript, and Tailwind CSS. Document parsing is handled via Mozilla's pdfjs-dist client-side engine. Because our business model does not rely on collecting user data or ad tracking, there are zero tracking scripts, analytics cookies, or backend databases.
