FAQs
What does Rezi do that Sausage Dog does not?+
Rezi gives you a numerical Rezi Score (0-100) showing how well your CV performs against ATS systems, plus AI mock interview practice and resume version management. It is a full CV builder. Sausage Dog tailors your existing CV to a specific job advert rather than building one from scratch.
Is Rezi available in the UK?+
Yes, Rezi is usable in the UK. It supports A4 formatting and PDF export. Pricing is in USD. It does not have specific knowledge of UK hiring conventions like NHS bands, civil service Success Profiles, or the standard UK two-page format expectations.
Is the Rezi lifetime deal worth it?+
At around £110 to £115 one-time, the Rezi lifetime plan pays back versus monthly billing in under 6 months. If you expect to job hunt again within 3 years, it is good value. For occasional job hunters, it is likely cheaper than a subscription.
Does Rezi rewrite my CV automatically?+
