SimplexityAI is a free, open-source desktop application that provides dedicated access to Perplexity AI's web-based search and research service. Built with Electron, it places the existing AI interface inside a standalone window with additional desktop controls. Users can search for information, ask questions, and access AI-generated responses without keeping a browser tab open. The application supports global shortcuts for searching highlighted text from other programs. It also includes reusable search prefixes, an integrated find bar, and adjustable zoom controls. System tray integration, automatic startup, and persistent sessions simplify everyday access. Available for Windows, macOS, and Linux, SimplexityAI stores application preferences locally while processing AI searches through the external service.
