1.1 Workflow description

Title: Create professional LinkedIn posts from Telegram messages using OpenAI text & image
Workflow name: Create professional LinkedIn posts from Telegram messages using OpenAI text & image

Create LinkedIn Post from Telegram Voice or Text Message with AI Image

Who's it for

This workflow is perfect for busy professionals, content creators, and marketers who want to publish polished LinkedIn posts without spending time on formatting or design. Send a quick text or voice message via Telegram, and get a fully formatted LinkedIn post with a relevant AI-generated image, post it immediately on LinkedIn.

Example use cases:

Entrepreneurs sharing business insights on the go without opening LinkedIn
Marketers creating consistent content during commutes or between meetings
Thought leaders turning quick voice notes into professional posts with visuals

How it works / What it does

Receive text or voice messages through a Telegram bot.
Transcribe voice messages using OpenAI's audio transcription.
Transform raw input into a professional LinkedIn post using AI formatting (proper structure, tone, and character limits).
Generate a relevant image prompt based on post content.
Create an AI image that matches the post topic.
Automatically publish the complete post (text + image) to LinkedIn.

How to set up

Create a Telegram bot via @BotFather and obtain your API token.
For self-hosted n8n users: Create a LinkedIn app at developer.linkedin.com to get OAuth credentials (Client ID and Client Secret).
Add the OpenAI API key, LinkedIn OAuth credentials, and Telegram API to n8n.
Assign your credentials to the Telegram, OpenAI, and LinkedIn nodes.
Deploy and activate the workflow.
Send a text or voice message to your Telegram bot and watch it create and post to LinkedIn!

Requirements

Telegram Bot Token
OpenAI API Key
LinkedIn OAuth credentials
n8n instance (cloud or self-hosted)

How to customize the workflow

Modify the LinkedIn Post Text prompt to match your personal writing style or brand voice.
Adjust image generation settings (model, size, style) in the Create Image node.
Add approval steps by routing posts to Google Sheets, Airtable, or Notion before publishing.
Create a second workflow to schedule approved posts for specific times.

Limitations and Usage Tips

Input Clarity: Voice messages should be clear and well-articulated for accurate transcription.
LinkedIn Character Limits: The AI formatter optimizes posts for 1,242-2,500 characters.
API Costs: Each post generation uses OpenAI API calls for transcription (if voice), text formatting, image prompt creation, and image generation. Monitor your usage to manage costs.
LinkedIn Rate Limits: LinkedIn API has posting frequency limits. Avoid bulk posting in short time periods to prevent rate limiting.

Send daily LinkedIn post drafts with Tavily, Groq Llama 3.3 and Gmail

## Quick overview This workflow runs daily at 8 AM to rotate through a topic list, research it with Tavily web search, generate a LinkedIn post and image prompt with Groq (Llama 3.3 70B), create a Pollinations.ai image URL, and email you the post with the image attached via Gmail. ## How it works 1. Runs every day at 8:00 AM on a schedule. 2. Selects today’s topic from a rotating list based on the day of the year. 3. Searches the web with Tavily to fetch up-to-date results for the selected topic. 4. Uses a Groq-hosted Llama model to write a LinkedIn post and a matching image prompt grounded in the Tavily results. 5. Builds a Pollinations.ai image generation URL from the image prompt and downloads the generated image file. 6. Emails the post text with the image attached via Gmail, and sends a text-only fallback email if image generation or download fails. ## Setup 1. Add a Groq API credential to the Groq Chat Model node. 2. Create a Tavily API key and configure HTTP Header Auth with `Authorization: Bearer <YOUR_TAVILY_KEY>` for the Tavily Search request. 3. Connect a Gmail OAuth2 credential and update the recipient email address in both Gmail send steps. 4. Edit the topic list in the topic-selection code step if you want different rotating themes. ## Requirements - Groq API key (free tier available) - Tavily API key (free tier — 1,000 searches/month) - Gmail account (OAuth2) ## Customization - Edit the topic list inside the "Pick Today's Topic" code node to change what subjects the post rotates through. - Change the Groq model in the "Groq Chat Model" node if you want a different LLM (e.g. a smaller/faster or larger Groq model). - Adjust the schedule trigger if you want a different posting time, or swap the Gmail "send to" address to deliver the draft to someone else for review. ## Additional info This workflow emails you a draft for manual review before posting — it does not post to LinkedIn automatically. If image generation fails, a text-only fallback email is sent instead so you never miss the post text.

Generate VEO3 videos from form ideas with ChatGPT, fal.ai, Drive and Gmail

## Quick overview This workflow collects a video idea via an n8n Form, uses OpenAI to turn it into an optimized prompt, generates an 8-second VEO3 video with native audio via fal.ai, saves the MP4 to Google Drive, and emails the Drive link via Gmail. ## How it works 1. Receives a submission from an n8n Form with the requester’s email, a plain-English video idea, and a selected style. 2. Uses OpenAI (via an AI Agent) to convert the idea and style into a structured VEO3 title and detailed prompt returned as JSON. 3. Cleans and parses the AI JSON, creates a filename-safe title, and sets the generation parameters to 16:9 and 8 seconds. 4. Submits the prompt to fal.ai’s queue endpoint for the fal-ai/veo3 model and gets a request ID. 5. Polls fal.ai every 30 seconds until the job status returns COMPLETED. 6. Retrieves the final MP4 URL from fal.ai, downloads the video, uploads it to Google Drive, and emails the Google Drive web link to the requester via Gmail. ## Setup 1. Create a fal.ai account, generate an API key, and replace `YOUR_FAL_AI_API_KEY` in the fal.ai HTTP request headers. 2. Add an OpenAI API credential in the OpenAI Chat Model node and select the model you want to use. 3. Connect Google Drive OAuth2 and replace `YOUR_GDRIVE_FOLDER_ID` with the target folder ID where videos should be saved. 4. Connect Gmail OAuth2 for sending emails, then activate the workflow and use the Form URL (path `veo3-video-generator`) to submit requests.

Generate presentation decks from prompts with Encelade

## Quick overview This workflow starts a presentation generation job in Encelade from a prompt and outline hints, polls Encelade for completion, and outputs the finished deck link (or stops with an error if generation fails). ## How it works 1. Starts when you manually execute the workflow in n8n. 2. Sends the topic, slide count, audience, tone, theme settings, and outline hints to Encelade to generate a 6-slide presentation. 3. Waits 20 seconds and then checks the Encelade session status using the returned session ID. 4. If the session phase is not finished, it keeps waiting and rechecking until the phase changes. 5. When the phase is "done", it returns the generated deck link and project PID. 6. When the phase is "failed", it stops the workflow and raises an error with the failure details. ## Setup 1. Install and configure Encelade credentials in n8n for the Encelade node. 2. Update the generation inputs (topic, page count, outline hints, audience/tone, theme mode, and media provider) to match the deck you want to create. 3. Ensure the workflow has enough time to complete by adjusting the 20-second wait interval if your Encelade generations typically take longer.
