Grammarly

Grammarly originally built its empire on spell-checking and basic grammar correction, but the introduction of its generative features completely shifted its identity. It no longer just tells you that you misplaced a comma; it will rewrite the entire paragraph for you. Because it exists as a browser extension, it follows users around the web, assisting them inside Gmail, Slack, LinkedIn, and Google Docs. This ubiquitous presence is its strongest selling point. Users do not have to open a separate application to get writing help. If an employee is staring at a blank email trying to figure out how to politely decline a meeting, they can click the Grammarly icon, type "tell them I'm too busy this week but maybe next month," and the software will generate a highly professional, tactful email draft right there in the inbox. For enterprise teams, the software acts as a brand enforcer. Managers can set custom style guides, ensuring that no one in the customer service department uses informal slang or incorrect product names. It monitors the tone of outgoing communications to ensure they sound confident, empathetic, or analytical, depending on what the situation requires. It bridges the gap between simple proofreading and active ghostwriting.
