For Organizations

Certify your team's AI literacy.

“Proficient in AI tools” on a résumé tells you nothing. Mentl's org platform gives team leads a structured way to train, assess, and certify every employee — with full visibility into who's ready and who needs more work.

01

Build a program

Pick skills and challenges manually, or describe your team context and let AI assemble the right curriculum for you.

02

Invite your team

Paste a list of emails or share a single link. Employees sign up and are auto-assigned their training program.

03

Track certification

A live matrix shows each employee's progress across every program item — certified, in progress, or not started.
