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.
