Generate Instagram carousels from Telegram prompts using OpenAI and Kie AI

This workflow acts as an automated Social Media Content Strategist, allowing you to generate a complete, 5-slide Instagram carousel with a corresponding caption directly from a single idea sent via Telegram. Instead of writing complex prompts for each slide, the workflow uses a specialized AI Agent to interpret your topic, apply your specific brand guidelines, and generate a full, structured educational carousel automatically.

By integrating a structured output parser, it ensures the AI generates a detailed plan for all 5 slides. These are then sent to an external, high-quality image generation API. A second AI agent simultaneously works on crafting an engaging, SEO-friendly caption for your post.

Use cases are many: Automated Content Creation:** Generate a complete, ready-to-post Instagram carousel from a simple topic idea in minutes. Rapid Idea Visualization:** Quickly prototype different educational content pillars for your social media strategy. Brand Consistency:** Enforce a specific visual style, color palette, and mood across all AI-generated carousels through a central brand guideline node.

Good to know

Full Carousel Generation:** The workflow doesn't just make one image; it creates a complete 5-slide carousel, including the visual concepts and text overlays for each slide. Dual AI Agents:** It leverages two distinct AI personas: a "Senior Content Strategist" to structure the carousel and an "Instagram Copywriter" to write the caption. Polling System:** It includes a smart "Wait" and "Check Status" loop to handle the asynchronous nature of the external image generation API, ensuring it retrieves the content without errors once it's ready. Security:** It features a Chat ID filter on the trigger to ensure only authorized users can initiate the workflow.

How it works

Trigger: You send a content idea (e.g., "5 tips for better time management") to your configured Telegram bot. Validation: The workflow first checks if the message comes from an authorized Chat ID. Content Strategist (AI Agent): An AI agent takes your topic and the predefined "Brand Guideline" to create a detailed 5-slide plan, outputting a JSON object with prompts for both the visuals and text overlay of each slide. Caption Copywriter (AI Agent): In parallel, a second AI agent writes an engaging, SEO-friendly Instagram caption based on the carousel prompts. Image Generation: The workflow sends the 5 slide prompts to the external image generation API (Kie AI) to create the visuals. Status Polling: It waits for a set duration and then repeatedly checks the API with the unique task ID until the images are fully generated and ready for download. Delivery: The final high-resolution carousel images and the generated caption are sent back to you via Telegram, ready to be posted.

Setup steps

Telegram: Create a bot via @BotFather on Telegram. Get the API Token and add it to the Telegram Trigger node's credentials. Send a message from your account, run the workflow once, and copy your Chat ID from the output into the IF node to authorize yourself. OpenAI: Connect your OpenAI credentials to the "Generate Carousel Content" and "Generate Caption" nodes. Image Generation API (Kie AI): This workflow uses api.kie.ai for image generation. You will need to create an account with them to get an API key. Add this key as a new Header Auth Credential in n8n and select it in the "Generate Carousel Images" and "Retrieve Carousel Images" nodes. Brand Guideline: Open the "Set Brand Style" node and replace the placeholder text in the style variable with your specific brand colors, typography, and overall aesthetic. Execution: Activate the workflow and send a simple topic to your bot to start the content creation process.
