ContentBrief.io vs Serpodo

ContentBrief.io generates AI-powered SEO content briefs from search results. Enter a keyword to analyze the top 10 ranking pages, including their word counts, headings, content structure, and gaps. Briefs can include People Also Ask questions, related searches, and semantic keywords. An outline builder creates H2 and H3 structures with talking points based on ranking pages. The workflow moves from keyword entry to brief review and export, and generation takes about 30 seconds. Briefs can be copied or exported to a writer; PDF export is included in Freelancer Pack, while Agency Scale includes API access. The service is aimed at content teams, SEO agencies, freelance writers, and founders. Freelancer Pack costs $29 a month for 10 briefs per month. Agency Scale costs $99 a month for 50 briefs per month, team sharing, priority support, and API access. Unused briefs do not roll over, and subscriptions renew automatically unless cancelled before renewal.
