Casual is a real skill too
Many ESL learners write very formal English even when the situation is casual. That can feel strange in friendly group chats. AI helps you match the relaxed style your American coworkers and neighbors use.
What makes English casual
- Short sentences
- Contractions: "I'm", "don't", "can't"
- First names — "Hi Sarah" not "Dear Ms. Sarah"
- Sign-offs like "Thanks!" or "Cheers,"
- Small jokes or warm phrases like "Hope your week is going well!"
Group-chat patterns
Group chats (Slack, Teams, WhatsApp) use even shorter messages. "sounds good!" or "works for me" or just an emoji is enough. AI can show you what a normal short reply looks like.
Words to know
- casual — relaxed, friendly
- contraction — short form like "I'm" for "I am"
- small talk — short, friendly chat about easy topics
- sarcastic — saying the opposite of what you mean
- harsh — too strong or rude
The big idea: friendly English is short, warm, and direct. AI shows you the rhythm.
