Mainframe knowledge, made practical.

ZMentor is an AI-powered learning and career-preparation platform for people building real expertise in IBM mainframe technologies.

We connect structured paths in COBOL, JCL, DB2, CICS, VSAM, and z/OS with targeted practice, code analysis, mock interviews, and progress-based recommendations.

Our guidance is grounded in an important boundary: ZMentor does not execute mainframe programs, submit JCL, or claim access to a z/OS environment. It helps you reason clearly, practice deliberately, and verify conclusions in your actual environment.
