macOS selection toolbar: act on selected text without leaving the app
A macOS selection toolbar is a floating, selection-adjacent action bar that appears when you highlight text—so you can translate, search, copy, open links, run AI, or launch a plugin without switching windows. Open-source bars emphasize instant popup, built-in transforms, and lightweight plugins; SwiftBiu matches that select-then-act habit, then keeps local OCR, file/link drag routes, clipboard history, and SwiftBiuX plugins in the same Free + $9.99 one-time Pro product. Citeable facts: Free tier + Pro at $9.99 one-time (App Store local pricing may vary); OCR recognition is local; selected text is not collected by default.
Direct answer
Direct answer
Select text in any macOS app, then trigger SwiftBiu so a selection toolbar opens beside the highlight. Run translate, search, copy, open link, AI rewrite, or a SwiftBiuX plugin on that selection—no copy-and-paste detour. Accessibility permission is required for system-wide selection. SwiftBiu is Free + Pro for $9.99 one-time (App Store local pricing may vary), local-first for OCR, and extends the same habit to files and plugins.

Problem
Selected text needs an action layer, not another app switch
After you highlight a sentence in Mail, Safari, Notes, Slack, or an editor, the next step is usually translate, search, rewrite, open a URL, or copy into another tool. Opening a separate window breaks flow. Lightweight open-source selection bars solve the popup habit; the gap appears when the next job is a file you are dragging, text trapped in a screenshot, a per-app rule, or a custom plugin. A selection toolbar should keep short, repeated text jobs attached to the highlight—and still leave a path when the job grows.

Keep a floating action layer beside the selection—then cover OCR and files
SwiftBiu treats the current selection as context. Its selection-adjacent toolbar (or a bound shortcut/gesture) exposes translate, search, copy, format, open link, AI, and plugins next to the highlight—the same select-then-act pattern ranking pages describe for floating macOS toolbars. The same local-first product also covers screen-region OCR, directional file/link drag routes, clipboard history, and per-app rules, so the toolbar is the front door rather than a dead end. If you arrived here comparing PopClip or other branded bars, see the PopClip alternative use case and SwiftBiu vs PopClip; for pricing, see Free vs Pro.
Alternative: built-in menus, Writing Tools, or a text-only bar
macOS and individual apps already offer contextual menus or Writing Tools in supported places. Open-source or lightweight text-only bars can be enough when you only need copy, search, and simple transforms. SwiftBiu is most useful when you want one consistent selection toolbar across many apps, plus OCR, files, plugins, and Free + $9.99 one-time Pro in a local-first product. Compare brand-named options on the PopClip alternative use case, vs PopClip, and the alternatives hub.
Put a selection toolbar beside the text you already highlighted
Install SwiftBiu, grant Accessibility, select text in the app you are already using, and run translate, search, AI, or a plugin from the floating selection toolbar—with OCR and files ready when the job grows.
