If that value is \"auto\", write it in the SAME language as the user's message.\n\nCAPTION RULES:\n- Open with a strong scroll-stopping hook (max ~10 words) on its own line.\n- 3-6 short paragraphs, 1-2 sentences each, with line breaks for readability.\n- Conversational, authentic, first person. No corporate buzzwords.\n- Use ONLY the information in the user's message. Never invent facts.\n- End with one clear question or call to action.\n- Plain text only: NO markdown, NO bold, NO headings.\n- Max 3 relevant hashtags on the last line (optional).\n- Max 2 emojis in the whole caption.\n- Keep it under 2200 characters so it fits every platform.\n\nIMAGE PROMPT RULES:\n- Describe ONE clean, modern, professional image that visually represents the main idea (use a metaphor, not literal text).\n- No text, words, logos, or identifiable real people in the image.\n- Mention subject, setting, style, lighting, colors and composition.\n\nReturn ONLY the structured object with 'caption' and 'image_prompt'."

An AI turns it into one polished, ready-to-publish caption, generates a matching image, and publishes everything to **LinkedIn, Instagram, Facebook and Threads** through [Blotato](https://blotato.com/?ref=firas) \u2014 then confirms back on Telegram.\n\nOne idea in. Four posts + one image out. No copy-pasting, no reformatting per network.\n\n## How it works\n1. **Telegram Trigger** receives your voice note or text.\n2. **Configuration** centralises every setting a beginner might change.\n3. **Route by input type** sends voice to transcription, text straight through.\n4. **Transcribe voice** (OpenAI Whisper) turns speech into text.\n5. **Generate social post** (AI agent) writes one caption + an image prompt.\n6. **Create image** (OpenAI gpt-image-1) generates the visual.\n7. **Upload image to Blotato** hosts the image and returns a URL.\n8. **Post to LinkedIn / Instagram / Facebook / Threads** publishes caption + image.\n9. **Notify on Telegram** confirms and shows the caption that went out.\n\n## Setup\n1. Create a Telegram bot with **@BotFather**, put the token in a Telegram credential, and select it on the 3 Telegram nodes.\n2. Add your **OpenAI** API key and select it on *Transcribe voice*, *OpenAI Chat Model* and *Create image*.\n3. Connect your **[Blotato](https://blotato.com/?ref=firas)** account, then on each *Post to \u2026* node pick the matching social account in the **Account** dropdown (Facebook also needs a Page).\n4. Open **Configuration** and adjust the 4 variables if needed.\n5. **Activate** the workflow, then send a voice note or a message to your bot.\n\n## Requirements\n- **Self-hosted n8n** (or n8n Cloud with Verified Community Nodes) \u2014 Blotato is a community node.\n- Telegram Bot token\n- OpenAI API key (Whisper + gpt-image-1)\n- A [Blotato](https://blotato.com/?ref=firas) account with LinkedIn, Instagram, Facebook and Threads connected\n\n## Customization\n- Change the writing style, language or length in the **Generate social post** system prompt.\n- Set `output_language` to `auto` (match the message), `English`, `French`, \u2026\n- Swap `image_size` / `image_quality` in **Configuration**.\n- Add or remove a network: disable the *Post to \u2026* node you don't want.\n- Want a human check first? Add a Telegram approval step before the *Post* nodes.\n\n---\nNeed help customizing?\nContact me for consulting and support : [Linkedin](https://www.linkedin.com/in/doctor-firass/)\n\n# MY NEW YOUTUBE CHANNEL\n\ud83d\udc49 [Subscribe to my new YouTube channel](https://www.youtube.com/@DrFiras_AI). Here I'll share videos and Shorts with practical tutorials and FREE templates for n8n.\n\n[](https://www.youtube.com/@DrFiras_AI)"
