Writing, editing & translation
Tools that draft emails and reports, fix spelling and tone, and translate. A general chatbot can do it, but dedicated editors and translators keep the original formatting and use terms consistently. This is a category with many Korean-made services such as Papago and Bareun, so if Korean quality matters most, start with those.
