If a certain percent of the work is completed through research synthesis and multiple perspective alignment, why is said novel approach not worth lauding?

I've created a version of one of the resume GPTs that analyses my resume's fit to a position when fed the job description along with a lookup of said company. I then have a streamlined manner in which it points out what needs to be further highlighted or omitted in my resume. It then helps me craft a cover letter based on a template I put together. Should I stop using it just because I can't feed it 50 job roles and have it automatically select which ones to apply to and then create all necessary changes to documents and then apply?
