About María Castillo
Staff Writer, Marketing Tech
Miami, FL
María has spent a decade consulting for SMBs and mid-market companies across Latin America and the US on digital marketing strategy. She came to ToolsBrief because she was tired of recommending tools she’d read about but never personally stress-tested with a real client budget on the line.
She writes primarily in Spanish and focuses on how tools perform in real Latin American business contexts — which often means different pricing realities, different language model quality, and different levels of local market support than what English-language reviews account for.
Her reviews of Writesonic, Descript, and similar tools consistently include the perspective of “would I actually recommend this to a client in Bogotá, Mexico City, or Miami?” — a filter most AI tools coverage ignores entirely.
Specialties: SEO tools, CRM platforms, marketing automation, Spanish-language AI tool evaluation, Latin American market context
Background: Digital marketing consultant since 2014. Clients have ranged from family-run PYMEs to regional retail chains. Based in Miami with regular work across Colombia, Mexico, and Argentina.
