What is the difference between Calibr and Rezi?

Rezi is an AI resume builder focused on ATS optimization — it gives you templates, real-time content scoring, and keyword targeting against a job description. Calibr is a company-specific rewriter: it researches a target company and reframes your real bullets in that company’s hiring language. Rezi helps you build an ATS-friendly resume; Calibr helps that resume resonate with a specific employer.

Is Rezi or Calibr better for ATS?

Rezi is built around ATS-friendly formatting and keyword scoring, so for producing a clean, machine-parseable resume it is a strong specialist. Calibr surfaces role-relevant keywords too, but its focus is company-specific framing rather than an ATS score. Many people build in Rezi, then use Calibr to tailor the content per company.

Can I use Calibr and Rezi together?

Yes. Build an ATS-clean base resume in Rezi, then use Calibr to reframe its bullets for each specific company you target. The two cover different halves of the problem — format/parseability and company-specific resonance.

Where Rezi wins

If you're starting from a blank page or your resume isn't ATS-clean, Rezi is a strong specialist. The templates are built for parseability, the real-time score keeps you from shipping a bullet with no metric, and the keyword targeting against a posting is useful. For building a solid, machine-readable base resume, it does the job well.

Where Calibr wins

A resume that passes the ATS still isn't tailored to the company. Rezi's AI edits are template-based — the same generic "optimized" voice every builder produces — and it has no concept of how Goldman hires differently from Google. Calibr researches the specific company and reframes your real accomplishments in its language, without inventing anything. That company-specific fit is the thing a template-based builder structurally can't give you.

The honest recommendation

Use them in sequence. Build an ATS-clean base in Rezi if you need to, then run it through Calibr to tailor the content for each company you apply to. Rezi gets the resume built and parseable; Calibr gets it to resonate with the specific employer.
