Act as a senior UX writer with experience in design systems for digital products. I will describe my product and you will produce a complete voice and tone guide, ready for design and product teams to use across screens, emails and notifications. Product name: name What it does in one sentence: short description Target audience: who uses it, age range, context of use Brand personality (3 adjectives): e.g. trustworthy, no-nonsense, playful Personality we are NOT (anti-patterns): e.g. corporate, childish, overly technical Voice references or competitors: optional, e.g. Nubank, Notion, Duolingo Deliver: 1) Voice principles (4-6 short sentences that guide all copy) 2) Tone-by-context table: welcome screen, error, success, billing, cancellation, empty state, push notification 3) Always say / never say glossary (5 critical product terms) 4) Microcopy rules: buttons (verbs, word count), form labels, constructive error messages 5) Side-by-side examples: bad version → good version, for 5 different contexts 6) Accessibility and inclusion guidelines (neutral language, screen reader readability) Use practical language with concrete examples. The guide should fit on one A4 page when printed.
