CURATED AND CAUTIOUS
One front door for common form problems.
This helper combines the site’s curated field-label and validation-message knowledge. When wording is ambiguous or depends on nearby context, it says so instead of guessing.
HOW TO USE IT
Start with the exact text you can see.
Copy the field label or validation message, including useful terms such as 全角, 半角, カタカナ, or 文字以内. The result explains the likely requirement and links to a focused converter when one can help.
Error messages
Turn common validation wording into one concrete, bounded next action.
Private by default
Matching happens locally in the browser. No form text is submitted to AI or another external service.

Frequently asked questions
Does this use AI to translate my form?
No. It matches the text locally against curated field labels and validation-message patterns.
What if the wording is not recognized?
The helper provides only bounded general guidance and tells you that context is missing instead of inventing a specific requirement.
