In plain English
From the first job search all the way to an offer, Four-Leaf, run by Frank, helps people prepare. They can practice interviews out loud, reshape a resume and a cover letter for a specific job, and get ready to talk about pay. The AI reads the job post and the resume, drafts the new materials, and the user approves them before they go out. Job seekers pay a subscription while they are looking, because practice and rewriting take many hours. The AI does most of the drafting and the billing, while Frank checks quality, helps users, and shares Four-Leaf in career communities.
