What is Spellr?

Spellr is a writing assistant that combines several tools into one platform: automated proofreading, plagiarism detection, and SEO optimisation. It's designed for anyone who writes regularly, whether that's content creators, students, marketing teams, or business professionals. The tool checks for spelling, grammar, and style issues, then flags potential plagiarism concerns and suggests SEO improvements to help content perform better in search results. Rather than requiring you to switch between multiple services, Spellr brings these functions together in a single interface.
