n8n Telegram to Bilingual Social Posts with Gemini for Instagram & LinkedIn

Turn a Telegram “/idea” into a bilingual Instagram carousel + infographic (Arabic/English) with Gemini

This n8n workflow listens for new Telegram messages starting with /idea, then uses Google Gemini to generate bilingual (Arabic/English) social content, render a 5-slide Instagram carousel and a matching infographic, and publish them to Instagram, Facebook, and LinkedIn through approval steps—with images hosted via Google Drive.

What this workflow does

• Telegram trigger + command filter: Starts on new Telegram messages and only continues when the message text begins with /idea.
• Idea extraction & brand kit setup: Extracts the idea text and chat/brand kit settings (including colors, fonts, illustration style, and target social account IDs).
• Gemini content planning: Uses Google Gemini (including a grounded web search tool when needed) to generate a structured bilingual plan for:
  • a 5-slide carousel (Arabic/English),
  • captions and hashtags,
  • infographic copy, plus Facebook and LinkedIn versions.
• AI image rendering: Generates each carousel slide image with Gemini image generation following fixed brand identity rules, then sends slide previews back to Telegram.
• Human approval: Waits for Telegram approval before publishing.
• Public image hosting + publishing: Uploads approved slides to Google Drive, makes them publicly readable, then publishes the carousel to Instagram via the Facebook Graph API. The workflow also renders the infographic, sends its preview to Telegram, and after approval posts it to Facebook and as a LinkedIn image post.

Use cases

• SaaS marketing teams: convert weekly campaign ideas shared in Telegram into bilingual social assets.
• Automation engineers: standardize Gemini-driven multilingual content production with controlled publishing.
• Founders: prototype rapid Arabic/English content workflows with review gates before publishing.

• n8n nodes/integrations: Telegram, Google Gemini (PaLM API), Google Drive (OAuth2), Facebook Graph API (Instagram Content Publishing permissions), and LinkedIn.
