Yes. Checking, importing, editing and exporting are unpaid, there is no premium tier and the exported PDF carries no watermark. For what Rezi costs today, read their own pricing page — prices change too often for a figure here to stay accurate.

Do I need an account to use ATSPrep?

No — there is nothing to sign up for, and the resume file is read in your browser rather than uploaded. Rezi works differently: an email account is required before you can build anything.

Can I use both ATSPrep and Rezi?

Yes, and for most people that is the sensible answer. What Rezi does better: writing the resume for you. If you are staring at an empty page, Rezi's generation and rewriting tools will get you to a full draft faster than ATSPrep will — ATSPrep checks and scores what you have, it does not invent bullet points. If you write the resume there, drop the finished PDF into the ATSPrep importer: it reads that file with a real PDF text extractor and reports what came out of it — whether the text layer is machine-readable, whether the layout resolves to one column, and whether your contact details survived.

AI resume builder

ATSPrep vs Rezi

An AI resume builder that drafts and rewrites content for you, then scores the result against its own ATS criteria.

ATSPrep is not that. It reads your existing PDF the way a parser does and shows you what came back out of it, then verifies the file it exports for you the same way — free, with no account, and without the file leaving your browser.

Comparison point	ATSPrep	Rezi
Account needed	No	Yes
Where the file is read	In your browser	On their servers
Built around	Checking the file you already have	Generating the writing
Price	Free, no paid tier	See their pricing page

No price is quoted here on purpose. Vendors run promotions and regional pricing, so a number copied into this page would be stale within weeks. The link always resolves to today's figure.

From their own documentation

What Rezi says about your resume

Resume content is stored on Rezi's servers, which is what makes the account and the cross-device editing work.

“you may also provide us with information about you in other forms (such as the content on your resume)”

Source: Rezi privacy policy

None of that is a criticism. Storing the document server-side is what makes an account, saved versions and cross-device editing possible, and those products could not work any other way. ATSPrep made the opposite trade: it parses and exports in the browser, which is why it can be free and why there is nothing to sign up for — and also why it cannot save your work to the cloud.

What you actually get

The extraction, not a grade for it

Bring the PDF Rezi produced and ATSPrep runs it through a PDF text extractor, then shows you what came back out. The same check runs again on the file it exports for you.

ATSPrep import dialog reading an uploaded PDF: it lists 216 words recovered, 2 roles, 7 bullets and 15 skills, the name, email, phone and location it pulled out, then a How your current file reads panel with six passing checks including machine-readable text, single-column layout and glyph encoding. — An imported PDF, read the way a parser reads it. A two-column layout or an image-only export fails these checks immediately — which is the thing a score out of 100 cannot tell you.

The actual decision

Which one you should use

Choose Rezi if

You are starting from nothing and want the first draft written for you.
You would rather edit AI-generated bullets than write them from scratch.
You want your resume saved to an account and editable from any device.

Writing the resume for you. If you are staring at an empty page, Rezi's generation and rewriting tools will get you to a full draft faster than ATSPrep will — ATSPrep checks and scores what you have, it does not invent bullet points.

Choose ATSPrep if

You already have a resume and want to know what a parser recovers from it.
You do not want to create an account or hand over the document to keep a copy.
You want each bullet judged on whether it carries checkable evidence, not rewritten into something more confident than the truth.

Verdict

You can use both, and most people should

These two are complements more often than rivals. Rezi is a drafting tool; the risk with any generator is that it produces fluent bullets that assert results you cannot defend in an interview. ATSPrep is the opposite discipline — it reads what you wrote, flags the claims that carry no evidence, and shows the extracted text so you know the file survives the machine. Draft wherever you like; check the export before you send it.
