Purifai is a Mac application that cleans text formatting when copying and pasting between different applications. It removes unsupported styles while preserving the structure that the destination application understands, ensuring text pastes cleanly into Mail, Docs, Slack, Word, Teams, and Notion.

The key features include destination-aware cleanup that adapts formatting to different applications, preservation of consistent structure including lists, spacing and paragraphs, completely offline operation with all cleanup happening locally on your Mac, blazing fast performance that works instantly, no tracking or data collection, and native optimization for Apple Silicon with macOS performance.

The product works through a simple three-step process: copy text from any source including AI tools or browsers, paste into Purifai which cleans formatting with the destination in mind, and then paste the cleaned text into your target application where it fits naturally without requiring manual rework.

Benefits include eliminating the need to manually fix formatting issues when pasting text, maintaining privacy since all processing happens offline on your device, and saving time by avoiding the frustration of broken formatting in email, chat, and document applications.

The target users include professionals who frequently copy and paste text between different applications, particularly those working with AI-generated content or web content that often has incompatible formatting. The application is specifically built for macOS with native Apple Silicon optimization.
