What an analyzer, builder, parser, matcher, and cover letter tool each do, which one to reach for at which point, and where the overlap between them is.
Reviews a finished resume for structure, keyword coverage, and bullet quality, and returns a score with the reasoning behind it. Useful when a resume exists and is not getting replies, because it tells you which of the three is the actual problem rather than leaving you to guess.
Extracts the document into structured fields the way an applicant tracking system would, then shows you the result. This is the only check that answers whether your titles, dates, and skills survive the read at all, which is a separate question from whether the content is good.
Flags the formatting that causes extraction to fail: tables, columns, headers, graphics, unusual fonts, and file type. A resume can score well on content and still fail here, which is why the two checks are reported separately rather than rolled into one number.
Compares one resume against one posting and lists what the role asks for that your resume never says. It is the tool to use once per application rather than once per resume, because the answer changes with the posting even when the resume does not.
Pulls the terms a posting is screening for and ranks them by how central they are, rather than by how often they appear. Boilerplate repeated three times in a legal footer should not outrank the one skill the role is built around.
Produces the documents themselves from ATS-safe templates with Word and PDF export. The builder is where you act on everything the checks told you, and keeping resume and letter in one place is what stops the two drifting apart in wording.

Most people submit a resume without knowing how a screening system will read it, and reach for whichever tool they found first. The categories are genuinely different, though the marketing around them rarely says so. What follows is what each type of tool does, what it cannot do, and the order that saves the most wasted effort.
Step 1
Run the extraction check first, because everything downstream depends on it. If half your experience section never makes it out of the file, a keyword score calculated on what did survive is measuring the wrong document. This is the step people skip and it is the one that most often explains silence.
Step 2
Structure and bullet quality are properties of the resume, so checking them repeatedly across applications tells you nothing new. Keyword fit is a property of the pairing, so it genuinely needs re-running for each posting. Splitting them this way removes most of the repeated work.
Step 3
Reading a list of recommendations and mentally noting them is how they get lost. Make the changes in the document while the report is open, then re-run the check on the export rather than on the draft.
Step 4
The preview shows how your editor renders the document. What an employer receives is the exported file, and the two are not always the same. Confirming the export is a thirty-second step that catches problems the preview cannot show you.
No public tool can reproduce a specific employer's configuration, and any score presented as the number an employer will see is overstating what it knows. Scores are useful as a before-and-after on your own edits, not as a prediction. Use the written reasoning; the number is just the handle.
A template cannot rescue a bullet that describes a duty instead of a result. If the analysis says your bullets are weak, switching layout will change nothing. The builder solves structure and speed; the writing is still yours.
A matcher tells you which terms are missing, not which ones you should honestly claim. Every suggestion needs the judgement of whether you have actually done the thing, and adding terms you cannot defend is worse than the gap was.
Tools will happily report on one document forever, and a good score on a resume sent unchanged to every role is not the win it looks like. The point of the matcher is that the target moves.
