The things people ask first
What happens to your resume, whether anything gets invented, how this differs from a keyword checker, and whether it works outside office jobs.
A free scan is read once and deleted immediately after the report appears. With an account it stays until you delete it, and one button in settings wipes everything. It is never used to train anything.
No, and this matters more than anything else here. Rewrites only restructure what you already wrote. If a line needs a number to land, it marks the gap and asks you for the figure rather than inventing one.
Keywords are the easy half and every tool does them. The harder half is that most resumes list responsibilities instead of results, which is what a human rejects on. Jobstein shows you both and fixes the second.
Yes. It reads the posting in front of it rather than working from a fixed list of roles, so nursing, teaching, trades and hospitality come back as usefully as marketing does.
