SwiftBiu

SwiftBiu is a macOS‑only productivity assistant that lets users invoke AI‑driven actions directly on selected text in any application. When text is highlighted, a lightweight toolbar appears, offering one‑step commands such as translation, image generation, or custom workflows defined by plugins. The tool supports multimodal AI capabilities, including text‑to‑text and text‑to‑image processing, and can be extended with JavaScript plugins and HTML mini‑programs that run locally.

The platform is built for speed, leveraging native macOS performance to keep the experience responsive while handling both simple utilities like currency conversion and more complex, user‑defined actions. A free tier provides essential tools and a single plugin, while a paid Pro license unlocks unlimited extensions, simultaneous plugin usage, and priority support.

Developers can create and share plugins using a simple manifest format that specifies actions, icons, and required permissions, enabling community‑driven expansion of the assistant’s capabilities. SwiftBiu aims to streamline repetitive text‑based tasks by integrating AI directly into the user’s existing workflow.
