The post must be written primarily in Thai, with Chinese and Pinyin where appropriate. It should be easy to read, visually appealing with emojis, and encourage interaction.\n\n# INPUT:\n1. Thai Word: {thai_meaning or slang}\n2. Chinese Word: {chinese_character}\n3. Pinyin: {pinyin}\n4. Post Ideas : {ideas}\n\n# INSTRUCTIONS & STRUCTURE:\n1. Engaging Hook (\u0e1b\u0e23\u0e30\u0e42\u0e22\u0e04\u0e40\u0e1b\u0e34\u0e14):\nStart with a relatable question or a captivating statement in Thai to grab your audience's attention.

How this works
Effortlessly generate and publish engaging Facebook posts by simply chatting with an AI assistant, saving hours of manual content creation and design work for busy social media managers and small business owners. This workflow transforms a casual conversation into polished visuals and captions, leveraging integrations like Recraft.ai for image generation and Facebook Graph API for seamless posting. The key step involves an AI agent crafting tailored post content from your input, followed by structuring and overlaying text on custom-generated images to create ready-to-share assets.
Use this workflow when you need quick, AI-powered social media updates without design expertise, such as promoting weekly offers or sharing blog snippets via chat prompts. Avoid it for high-volume posting that requires strict compliance checks, like regulated industries, or when custom analytics are essential beyond basic scheduling. Common variations include adapting the chat trigger for Slack inputs or swapping Recraft.ai for DALL-E to match brand aesthetics.
