While curriculum vitae (CV) or resume is for job seekers, pitch deck (or business plan) is for aspiring entrepreneurs.
For your resume building, we like MyPerfectResume.
For coming out with one-page pitch deck and comprehensive business plan, we recommend LivePlan by Palo Alto Software.
Both of them are paid software with excellent UX and text templates. Your final copy is visually appealing with powerful text content. Both of them have comprehensive collection of text templates under variety of categories/niches.
Not ready to go for a paid service? One hack is that you can generate ideas/content using the above tools. Then copy the same to your source (for instance MS Word if you are preparing CV using MS Word).
