Spell Catcher
Spell Catcher is a system-wide spell checking and writing utility for macOS that monitors text input across applications. It offers automatic typo correction, shorthand glossaries for expanding custom abbreviations, a built-in dictionary and thesaurus, and the ability to check spelling in emails, documents, instant messages, and other text fields without leaving the active application. It was particularly popular among writers, editors, and professionals who needed comprehensive spelling and vocabulary tools integrated directly into their workflow.

1 suggestionSpell Catcher was discontinued many years ago — the last released version (10.4.1) dates to the mid-2000s and was only officially supported up to Mac OS X Lion. The app has not been updated by the developer since then and no native Apple Silicon build was ever created. The application will stop working entirely when Apple removes Rosetta 2 in macOS 28 (late 2027), and it may already exhibit compatibility problems on current macOS releases. Built-in system spell checking in macOS has improved significantly since Spell Catcher's heyday — Mail, Pages, Word, and nearly every modern text editor now offer real-time spell checking, thesaurus lookup, and auto-correction natively. If you need advanced grammar and style checking beyond the built-in spell checker, consider Grammarly (free and paid versions available on the Mac App Store) or Hemingway Editor, both of which are actively maintained and run natively on Apple Silicon.
