Japanese content editing — one brief, multiple formats. AI-assisted, self-initiated writing sample for a fictional cafe. I adapted a fact sheet into a LINE announcement and an email, keeping the product, price, dates, serving hours, and dine-in condition consistent. The visual shows the brief and a concise LINE version. No unsupported stock, reservation, allergy, or performance claims were added. This demonstrates content organization and fact checking, not a paid client campaign.
