Practising a language.
WHERE IT HELPS
Explaining grammar when the textbook did not Conversation practice at any hour Correcting your writing and explaining the corrections Vocabulary in context
FOR CONVERSATION PRACTICE
"Have a conversation with me in [language] at [level]. Correct my mistakes after each message."
Genuinely useful where finding a practice partner is difficult.
FOR CORRECTION
"Correct this and explain each correction."
The explanation matters more than the correction.
WHAT IT DOES BADLY
Pronunciation, which it cannot hear Regional variation and register Languages with limited training data
FOR NIGERIAN LANGUAGES
Coverage varies considerably. Test before relying on it.
WHAT IT CANNOT REPLACE
Speaking with people. Language is social.
WHAT TO VERIFY
Anything you will use in a real situation, with a native speaker.
THE PRACTICAL VALUE
Unlimited patient practice, which is the thing most learners lack.
