GradeProof.com isn't trying to beat Grammarly at its own game—it's playing a different, more tactical one. With just 8 employees and a modest $600k in revenue, this AI writing assistant has carved out a niche by embedding itself directly into the workflows of Google Docs power users.

"They aren't building an audience; they're infiltrating one. GradeProof's strategy is to become the default proofreading layer inside Google Docs, not a destination website."

The tech stack tells the story of a lean, performance-focused operation. They use Next.js for speed and PWA capabilities for offline utility. Most notably, they leverage Google Tag Manager, Analytics, and Ads—tools designed to track and optimize a user journey that likely ends inside the Google Workspace ecosystem, not on their own site. They aren't spending resources on complex backend infrastructure; they're focused on the browser extension and API integration.

• Revenue Efficiency: $75k revenue per employee suggests high margins and low overhead.
• Traffic Quality over Quantity: 1,162 visits with 42% direct traffic indicates a loyal, returning user base.
• Platform Dependency: 100% of traffic share is 'undefined' (likely direct/extension traffic), proving they own the distribution channel, not the search engine.
