The earliest “grammar checkers” were basically programs that checked for punctuation and style inconsistencies, rather than finding many actual grammatical errors. The first system was called Writer's Workbench, and was a set of writing tools included with Unix systems as far back as the 1970s.[1][2] The whole Writer’s Workbench package included several separate tools to check for various writing problems. The ‘diction’ tool checked for wordy, trite, clichéd or misused phrases in a text.
