AI-Powered LinkedIn Viral Content Generator & Telegram Bot

Disclaimer:
This workflow uses community-contributed nodes which are not officially maintained by n8n. Please test thoroughly before running in production. Do not use this template in production without your own independent validation.

Overview

This workflow empowers you to generate highly viral LinkedIn posts, including both compelling copy and AI-generated custom images, directly from a Telegram chat interface. Leveraging AI-powered research, GPT-based content creation, and community-based integrations, it creates a seamless automation: from prompt to trend analysis, viral copywriting, image generation, and message delivery—all in one flow.

Node-by-Node Workflow Explanation

  • Telegram Trigger: Starts the workflow from a specified Telegram chat by capturing user prompts.
  • Expert Algo (AI Analysis): Uses OpenAI and Tavily to research current LinkedIn trends, analyzes top-performing content, and produces a content framework plus an AI image prompt.
  • Structured Output Parser: Validates and formats the AI's returned JSON output.
  • CM Junior: Generates three LinkedIn post drafts in your own style, based on the viral framework and rules.
  • Structured Output Parser1: Ensures correct JSON for the drafted posts.
  • Community Manager: Evaluates the draft posts using additional trend analysis via Tavily, selects the one most likely to go viral.
  • Structured Output Parser2: Validates the community manager's single post output.
  • Generate Image: Calls the AI image generator on RapidAPI to create a picture for your post, using the recommended prompt.
  • Split Out/Download Image: Prepares and downloads the generated image file.
  • Send Telegram Photo and Message: Sends the chosen LinkedIn post and the generated image to your Telegram bot.

Setup Instructions

  1. Telegram: Create a bot using @BotFather and get your bot token and target chat ID.
  2. OpenAI: Register at OpenAI, obtain your API key.
  3. Tavily: Register at Tavily and get your API key.
  4. RapidAPI (AI Image Generator): Create an account, subscribe to the "ai-text-to-image-generator-flux-free-api", and copy your API key.
  5. Credentials: Use the n8n Credentials Manager to configure each key securely—never hardcode API keys into nodes.
  6. Workflow Personalization: Replace all placeholders like Telegram chat ID by referencing the credentials or environment variables.
  7. Testing: Run the workflow using your bot and ensure that no personal or sensitive data remains before publishing.

Additional Recommendations

  • Update the image generator, Telegram, OpenAI, and Tavily node credentials through the n8n Credentials panel.
  • Custom tailor prompts and output formatting as needed for your LinkedIn content strategy.
  • For security, do not share any personal API keys or chat IDs in your public template.

Generate Viral LinkedIn Content with GPT and Images using Telegram Bot Interface

This n8n workflow allows you to generate engaging LinkedIn content, complete with AI-generated text and images, all through a simple Telegram bot interface. It leverages OpenAI's GPT for content generation and external APIs for image creation, making it easy to produce viral-ready posts.

What it does

  1. Listens for Telegram Messages: The workflow is triggered when you send a message to your configured Telegram bot.
  2. Generates LinkedIn Content with AI: It uses an OpenAI Chat Model (via LangChain) to generate a LinkedIn post based on your input.
  3. Parses Structured Output: A Structured Output Parser extracts the generated content and image prompts into a usable format.
  4. Generates Images: It makes an HTTP request to an external API (likely an image generation service) using the extracted image prompt.
  5. Splits Content for Individual Posts: The workflow prepares the generated content and image for individual posting.
  6. Sends Content to Telegram: Finally, it sends the generated LinkedIn post text and the generated image back to you via Telegram.

Prerequisites/Requirements

  • n8n Instance: A running n8n instance.
  • Telegram Bot: A Telegram bot token and chat ID.
  • OpenAI API Key: An API key for OpenAI (for the GPT model).
  • External Image Generation API: An API endpoint and any necessary credentials for an image generation service (e.g., DALL-E, Midjourney, Stable Diffusion API). The current workflow uses a generic "HTTP Request" node, which implies you'll need to configure this with your chosen service.
  • LangChain Integration: Ensure the @n8n/n8n-nodes-langchain package is installed in your n8n instance.

Setup/Usage

  1. Import the Workflow: Import the provided JSON into your n8n instance.
  2. Configure Telegram Trigger:
    • Open the "Telegram Trigger" node.
    • Add your Telegram Bot API credential.
    • Ensure the "Updates" are set to Message.
    • Save and activate the workflow.
  3. Configure OpenAI Chat Model:
    • Open the "OpenAI Chat Model" node.
    • Add your OpenAI API key credential.
    • Review and adjust the prompt to guide the AI in generating LinkedIn content as desired.
  4. Configure HTTP Request (Image Generation):
    • Open the "HTTP Request" node.
    • Crucially, configure this node with the URL, method (e.g., POST), headers (e.g., API key), and body required by your chosen image generation API. The workflow expects an image URL in response.
    • The current setup suggests it takes {{ $json.image_prompt }} from the previous node, so ensure your image API can consume this.
  5. Activate the Workflow: Once all credentials and configurations are set, activate the workflow.

To use the workflow:

  1. Send a message to your Telegram bot. This message will be used as the input for the AI to generate LinkedIn content.
  2. The bot will respond with the generated LinkedIn post text and the corresponding image.

If AI returns non-JSON, keep “Return only a JSON array” as the last line of the prompt and keep jsonOutput enabled. Consider adding validation on parsing.warnings to gate Salesforce writes. For discounts/taxes in OLI: Standard OLI fields don’t support per-line discount amounts directly; model them in UnitPrice or custom fields. Replace the Composite API URL with your org’s domain or use the Salesforce node’s Bulk Upsert for simplicity.
