Platform Copy Guidelines

Twitter/X

• - HARD LIMIT: 280 chars total (CJK = 2 chars each, emoji = 2 chars, URL = 23 chars fixed by t.co)
• MUST count characters before output. If over 280, ruthlessly cut until under
• NO blank lines between sections — every newline costs a character
• NO bullet lists — too wasteful. Use short flowing sentences
• Lead with a hook (question or bold claim), not product name
• One short URL at end (counts as 23 chars regardless of length)
• 2-3 hashtags max, on same line as URL
• Optional: suggest a thread for details if content can't fit

• Use emoji section headers (📊🔧💡🔗)
• ✅ for checklist items
