CV Optimiser and a human CV review solve different problems. The tool is built for role-specific CV feedback before you apply; a human reviewer can still help with judgement, positioning and specialist career context.
Use CV Optimiser when you want to check one CV against one job description and see what to improve first.
A good human reviewer can add wider career judgement that a tool cannot fully replace.
For most applicants, the quickest route is to use CV Optimiser first, fix the obvious role-fit gaps, then consider a human review only if the application is high-stakes or complex.
No CV tool or reviewer can guarantee interviews, ATS acceptance, job offers or employer responses. Hiring depends on competition, timing, location, salary, experience level and employer judgement.
Paste your CV and a job description to see whether the core role-fit problems are obvious.
