The Verdict
Frase is built for content writers and seo freelancers, with a focus on serp-analysis and content-briefs. Zotero targets researchers and students and leads with reference-management and pdf-annotation.
On pricing, Frase is the clear winner for budget-conscious users — starting at $14.99/mo compared to $20/mo for Zotero. That $5.01/mo difference adds up quickly for growing teams.
