Prose — AI Writing Assistant

Polish what you write. Select text in any field and instantly improve clarity, fix grammar, or change tone with your own AI key.

Prose is an AI writing assistant for Chrome that improves your text directly where you type. Instead of switching tabs to a chatbot and pasting text back and forth, you simply highlight text on any website and use a floating toolbar to rewrite it instantly in place. Choose from quick actions like Improve, Fix Grammar, Shorten, Make Formal, or Make Friendly to match your goal in one click. Prose works across everyday writing surfaces, including standard input fields, textareas, and rich-text editors on sites like Gmail, Notion, LinkedIn, X, Slack, and more. It helps you write clearer emails, cleaner comments, stronger posts, and more polished messages in less time—without interrupting your workflow. You can bring your own API key and choose your preferred provider (Gemini or OpenAI), so you stay in control of usage and costs. Prose also includes optional style notes so you can teach it your tone, audience, and writing preferences for more personalized rewrites. Privacy is a core part of the extension: there is no Prose server processing your text. Your selected content is sent only when you trigger an action, directly to the AI provider you selected. Your settings and API key are stored locally in your browser. If you write online every day and want faster, better wording without extra friction, Prose gives you a practical “edit as you go” layer across the web.
