What Prose is
Prose is a desktop-only Chrome extension that corrects grammar and spelling in selected text while aiming to preserve the writer’s voice. Select text in Chrome, choose “Fix my text” from the right-click menu, and paste the corrected text from the clipboard. The maker says it works wherever you can type in Chrome, including Gmail, Slack, Notion, LinkedIn and Google Docs. Prose includes style suggestions and tone detection. Its free own-key option supports OpenAI, Claude and Gemini; you provide the API key and pay the chosen provider for usage. That plan costs nothing and allows unlimited fixes. A credit option costs $10 a month as a one-time purchase, with credits that never expire and no recurring billing. Only selected text is sent when a fix is requested. With your own key, text goes directly from the browser to the provider rather than through Prose servers. The terms focus on plain text and do not promise formatting preservation, translation, perfect accuracy or compatibility with every input field.
