Tailoring means one posting at a time: reorder bullets, tighten the summary, and surface skills the job searches for — without inventing experience you cannot defend in an interview.
Paste a single posting into the builder. The useful output is which requirements your CV already proves and which need a bullet you can add from real work — not a new CV for every title you ever considered.
Rewriting the entire document for every application is why people stop tailoring. Change the summary, the top bullets, and skill emphasis; leave unrelated history readable but shorter.
cvharbor rewrites from text already on the CV and facts you enter. It will not add employers, certifications, or metrics you did not provide. Annotated intent: posting wants Terraform — if your CV mentions it in a project bullet, tailoring promotes that bullet; if it never appears, the gap stays visible.
That is slower than one-click AI polish and safer when a hiring manager will ask how you did the thing you claimed.
Do not invent stack, patient groups, quota numbers, or team sizes. Do not rename a role to match a title you never held. Do not move dates to hide gaps.
Cover letters drawn from the same CV follow the same rule — see /cover-letter-examples for letter shape; fix the resume first when the gap is real.
The builder is the main loop: import or write the CV, attach one job, apply suggested edits you can defend. /tools compares cvharbor to keyword-score products when you want context before you start.
After tailoring, export and run the parse check from /ats-resume-checker or /resume-templates/ats so layout did not break while you edited bullets.
No. It can surface skills already implied by your bullets and flag JD keywords you cannot support. Adding fake tools makes interviews worse, not better.
The loop is the same: one posting, evidence-only edits. Market rules (length, photo, dates) stay in the profession guides on the blog.
Yes when the posting asks for a letter. Generate it from the same tailored CV so both documents cite the same facts.
