For Organizations
“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.
Pick skills and challenges manually, or describe your team context and let AI assemble the right curriculum for you.
Paste a list of emails or share a single link. Employees sign up and are auto-assigned their training program.
A live matrix shows each employee's progress across every program item — certified, in progress, or not started.
