Grammarly

Grammarly is an AI writing assistant that helps individuals and teams improve their communication. It offers features for grammar and spelling correction, tone adjustment, full-sentence rewrites, and generative AI for various content types. The platform integrates with numerous applications and provides tools for brand consistency and team collaboration.

Grammarly aligns well with the concept of an AI-powered writing assistant. It offers a wide range of AI writing tools for various purposes (general writing, job search, work, marketing, students), which are presented through a guided interface. Users can generate text by providing instructions, similar to filling out forms. It supports creative presets through tone adjustments and style guides. While it doesn't explicitly mention routing tasks to different underlying AI models, its extensive features and integrations imply a sophisticated backend. Grammarly has a clear tool catalog, user authentication with free/pro/enterprise tiers, and features like search, history, export, collaboration (for teams), and usage analytics. It also offers in-app tutorials and is mobile-responsive. The main difference is that Grammarly is primarily focused on text generation and refinement, not image generation, and it integrates into existing applications rather than being a standalone 'playground' platform.
