Cory Co-Writer

Cory Co-Writer is a Microsoft Word add-in for fast rewriting and editing inside your document. Select any text, enter a prompt such as “make this more concise,” “fix grammar,” or your own custom instruction, and Cory returns alternative versions you can replace, insert, or copy with one click.

The add-in is built for flexible writing workflows. You can choose your preferred AI provider and model in the task pane, including OpenAI, Anthropic, Google Gemini, Scaleway, AI-Flow.eu or a compatible OpenAI-style endpoint. Cory keeps the editing flow simple while letting you control the provider, model, and tone settings yourself.
