Why Use This Tool
Catches Agreement Errors
Detects mismatches between subjects and verbs — including tricky cases with collective nouns, compound subjects, and indefinite pronouns.
ESL-Focused Detection
Non-native speakers often struggle with agreement in English because many languages don't have this rule. This tool catches patterns specific to ESL writers.
Explains the Rules
Each correction includes an explanation of which agreement rule applies, helping you internalize the pattern.
Handles Tricky Cases
"Either/neither", collective nouns ("team is/are"), and phrases that separate subject from verb ("The box of chocolates was/were").
Who Is This For?
Students
Professionals
ESL Speakers
Content Writers
