PromptPolish removes the copy-paste loop from AI-assisted writing. Instead of opening a chat window, pasting a paragraph, waiting for a reply and pasting the result back, you select text directly on the page, pick or type a prompt, and the extension replaces the selection with the rewritten version. Because prompt templates are reusable, recurring tasks such as tightening a draft, changing tone, fixing grammar or translating a block of text become one-click actions.
The extension deliberately stays thin on infrastructure. You bring your own API key for the AI service you want to use, and PromptPolish only relays the request and the response. According to its Chrome Web Store disclosure, the developer does not collect or sell your data, and your credentials are stored locally and shared solely with the provider you define. That design keeps the extension free to run while giving you control over which model handles your content.
PromptPolish is a small, early-stage project — it has modest install numbers and few reviews, and its last store update was in December 2024. It is nonetheless available, installable and functional, and it suits users who want a minimal, privacy-conscious rewriting helper rather than a full writing suite.
