What is Co-Writer AI?

Co-Writer AI is a writing assistant that provides real-time word suggestions, plagiarism detection, and general writing support as you work. It sits alongside your writing process to catch potential issues and offer alternatives, making it useful for anyone producing written content regularly. The tool works on a freemium model, so you can try the core features without paying upfront. It's designed to help with grammar, vocabulary choices, and originality checks in one place rather than switching between multiple tools.
