SwiftBiu provides a context-aware floating toolbar that appears automatically when text is selected in any application. The app enables quick actions like translation, search, note-taking, and AI processing without switching contexts. Built natively with Swift and AppKit for responsive performance. ($5, one-time purchase)
The toolbar appears next to the mouse pointer immediately upon text selection, eliminating the need to navigate menus or remember keyboard shortcuts. Users can trigger actions like sending text to translation engines, search services, or AI APIs with single clicks. The extensible architecture supports custom workflows through JavaScript plugins and HTML extensions.
AI multimodal capabilities support text-to-text and text-to-image processing. The JavaScript API enables connections to external services including translation engines, note-taking apps, or custom internal APIs. This extensibility transforms the app into an automation platform rather than a fixed-feature utility.
All text processing occurs locally on the Mac with external service connections only when explicitly triggered by user actions. The native Swift/AppKit implementation ensures lightweight operation and fast launching without Electron or web-based frameworks.
Free version available with limited functionality. Paid version ($5 one-time purchase) provides full feature access including unlimited AI actions and custom plugin support.
System requirements: macOS (specific version requirements available on website). Native Apple Silicon and Intel support.
Limitations: Requires initial configuration to connect external services (translation APIs, AI services). Learning curve for JavaScript plugin creation. Free version limitations not clearly documented on website.
Alternatives: PopClip (text action utility), Alfred (universal launcher with workflows), Keyboard Maestro (automation platform).
Suitable for users who frequently perform text operations like translation, search, or AI processing across multiple applications. Particularly useful for multilingual workflows, content research, or anyone who regularly reformats, translates, or processes selected text. Best for users comfortable with customization who can leverage the JavaScript plugin system.
