Name the intention before choosing the register
Say what the message should accomplish: ask about availability, invite someone, explain a delay, or make a request. Then describe the audience in general terms. This gives Mocchi enough context to compare tone without needing personal names or a private conversation history. A short controlled message is the best place to start.
Keep the content stable during the first comparison. If the activity, relationship, and urgency all change, you cannot easily see which wording responds to politeness. You can add those other dimensions later after the basic contrast is understandable.
Compare two versions of a simple meeting question
明日、会える? is a casual question about meeting tomorrow. 明日、会えますか is a polite version of a similar question. Read both in an invented context and ask Mocchi what the ending changes. The pair is a starting contrast, not a guarantee that either line is the ideal message for every relationship or situation.

| Japanese | Romaji | Meaning |
|---|---|---|
| 明日、会える? | Ashita, aeru? | Can we meet tomorrow? |
| 明日、会えますか。 | Ashita, aemasu ka. | Can we meet tomorrow? |
Check for extra distance or urgency
A rewrite may include more than a different ending. It can make the request sound more tentative, more formal, or more demanding, depending on the wording. Ask which change serves the audience and whether it alters the practical intention. This prevents you from treating every longer sentence as merely the same message with politeness added.
Make your own changed message
Choose another day, activity, or short explanation while keeping the audience clear. Write the version yourself before asking for feedback. If you accidentally mix styles, ask Mocchi to show the mismatch and let you revise it. Producing a new message is a more useful check than recognizing the tone difference in a pair the tutor already completed.
Keep a context note with the expression
Save a short note describing who the message was for and what it was meant to do. Review the expression in another suitable context later rather than memorizing it as a universal polite or casual formula. Mocchi can help adapt examples to your goals, while the context note keeps the lesson connected to communication instead of an automatic replace-every-ending rule.
