This is the real question behind choosing between Rezi and EZProCV.
AI writing helps if you're stuck on how to phrase your experience, or you're tailoring many applications quickly. Rezi's tools can draft bullet points and suggest keywords, and that's a genuine advantage.
You may not need it if you already know your achievements and can describe them with numbers. A strong bullet is specific and checkable:
Cut monthly reporting time from 3 days to 1 by automating data pulls in Excel and Power BI.
No tool can invent that result for you. Whatever you use, read every AI-suggested line and remove anything that isn't true or that you couldn't explain in an interview. Our resume examples show before-and-after bullets you can adapt without AI.
If you want to tailor keywords by hand, compare the job description with your resume and use the employer's exact terms where they honestly apply. Columbia University's career center recommends exactly this, along with standard section headings and simple formatting.
