Grammarly operates a multi-tier writing assistance product deployed across 500K+ apps and websites, serving both consumer and enterprise segments. The tech stack spans Android, React, TypeScript, Go, and cloud infrastructure (GCP, AWS, Azure), with recent adoption of Coda and Superhuman while phasing out Quip, Notion, and Asana—a shift toward consolidation around fewer, deeper integrations. Active projects reveal a transition beyond writing into broader productivity workflows, paired with foundational work on data pipelines and secure-by-default architectures to support billions of daily events.
