Rezi

Rezi is AI resume software that helps job seekers create resumes designed to pass applicant tracking systems (ATS). The core problem it addresses is that many resumes are filtered out by automated ATS scans before a human ever reads them, so Rezi builds formatting, keyword targeting, and content quality into the writing process itself. The company states that 4.5 million people have used the product and that users have been hired at more than 1,000 companies.

Founded in 2015 and based in Seoul, South Korea, Rezi works around three connected steps: build, score, and target. Users draft a resume with AI writing assistance and ATS-compatible formatting applied as they type; the Rezi Score then evaluates the resume section by section; and a keyword scanner compares the resume against a pasted job description to surface missing terms. Beyond resumes, Rezi offers cover letter and resignation letter generators, AI interview practice, a job search tracker, a Chrome extension for auto-filling applications, a mobile app, and an MCP server for managing resumes inside AI assistants. A white-label Enterprise tier serves universities, agencies, and career sites.
