About Alex Rivera
Senior Editor, AI & Productivity
Austin, TX
Alex spent eight years as a product manager at B2B SaaS companies before making the switch to AI tools journalism. That background shows in his writing — he evaluates tools the way a PM would: by asking what problem it actually solves, who it’s really built for, and whether the pricing makes sense at scale.
At ToolsBrief, Alex leads coverage of AI writing assistants, LLM-powered productivity tools, and content creation platforms. He’s tested over 200 tools since 2022, and has a particular interest in tools that non-technical professionals can actually use without an engineering degree.
His rule of thumb: if a tool can’t improve your output within the first 30 minutes, it’s not ready for most people. He’s written extensively about Grammarly, Jasper, Claude, and the broader AI writing stack for entrepreneurs and content teams.
Specialties: AI writing tools, content automation, LLM evaluation, productivity software for non-technical users
Background: Former PM at two VC-backed SaaS companies. Started writing about AI tools in 2022 when GPT-3 made the category interesting enough to follow seriously.
