Term Butler

Term Butler is a menu bar app for translators and other language professionals. Select a term in any application (e.g. a CAT tool, a PDF, a teams chat, an email), press a hotkey, and Term Butler opens it in all your configured reference sources at once: dictionaries, terminology databases, client glossaries. Sources can open in separate tabs, separate windows, or a combined split view.

Features:

• Selection-based lookups: one hotkey searches a term in several sources simultaneously.
• Resource Library with about 290 preconfigured dictionaries, encyclopedias, and reference sites in 17 languages.
• Local glossaries: convert an Excel glossary with the included Glossary Converter and search it offline.
• Snippet Collector with Collect & Advance for CAT tools (memoQ, Trados, Phrase, and others) and one-key pasting into Microsoft Word for offline spelling and grammar checks — no data leaves the Mac.
• SmartText: global text expansion — type a short code, get the full phrase, in any app.
• Search History with a Recent Lookups menu that re-runs past searches.
• Optional text-only Clipboard History (off by default; entries marked confidential by password managers are ignored).
• Right-click lookups via the macOS Services menu.
• Unit Converter: select a value like 5 km or 100 °F and see the conversions in a floating panel.
• Character and Word Counter with width equivalents for UI length limits.
• Websites: up to ten frequently used pages, opened via number keys or individual hotkeys.
• Full configuration import/export as JSON.

All processing happens locally. Requires macOS 13 or later on Apple Silicon, and the Accessibility permission for global hotkeys.
