Which one’s better for fast, AI-powered writing support?
What is Grammarly?
Grammarly is a writing assistant that checks for grammar, spelling, and tone issues in real-time. It’s widely used in professional and academic contexts, and its browser and app integrations make it easy to use across platforms. The premium version also includes style and clarity improvements, plus a built-in AI writer.
What is Smart Keys?
Smart Keys is a MacOS app that puts AI shortcuts, like proofreading, translating, and rewriting, just a keystroke away. Instead of opening a new tab or copying content into an external tool, Smart Keys lets you select text anywhere and instantly run a pre-set or custom command. It’s minimal, fast, and blends right into your workflow.
