What Jasper is
Jasper is an AI marketing platform for brand voice, campaign briefs, and multi-channel drafts — blogs, ads, social, email, and product pages. Teams train Brand Voice and Knowledge Base assets so output stays on-message, then collaborate in shared workspaces with review workflows. Public Pro-style seats typically start around $49/mo with higher Business/Enterprise bands for SSO, governance, and volume. Strong when marketing ops need governed generation at scale; still needs human editors for claims, SEO truth, and legal review.
