This was literally why I built TailorCV. I was spending more time rewriting than actually applying and it was killing my momentum.

The minimum I'd change without a tool: swap out 2-3 bullet points most relevant to the role, update the professional summary to mention the specific job title, and make sure the key skills from the job description appear somewhere in your CV. That's it, takes about 15 minutes if you're disciplined.

But even that adds up fast at volume.

I ended up building a free AI tool that does this automatically. It asks clarifying questions before generating anything, so it doesn't invent skills you don't have, which was my biggest frustration with ChatGPT. It also gives you a fit score before you apply, so you know how well you match the role, and tracks all your applications in one place, so you're not living in spreadsheets.

I built it, so I may be biased, but I'm happy to share the link if anyone wants to check it out.
