1.1 Workflow description

Title: YouTube to telegram summary bot with Decodo & Gemini AI
Workflow name: YouTube to telegram summary bot with Decodo & Gemini AI

Stop wasting hours watching long videos. This n8n workflow acts as your personal "TL;DW" (Too Long; Didn't Watch) assistant. It automatically pulls YouTube transcripts using Decodo, analyzes them with Google Gemini, and sends a detailed summary straight to your Telegram.

Why You Need This

Save Time: Turn a 2-hour video into a 5-minute read (95% faster).
Don't Miss a Thing: Captures key points, chapters, tools mentioned, and quotes that you might miss while skimming.
Instant Results: Get a structured summary in Telegram within 30-60 seconds.
Multi-Language: Works with any video language that has YouTube captions.

Who Is This For?

Creators & Marketers: Spy on competitor strategies and extract tools without watching endless footage.
Students: Turn lecture recordings into instant study notes.
Busy Pros: Digest conference talks and webinars on the go.

How It Works

Send Link: You message a YouTube link to your Telegram bot.
Scrape: The bot uses the Decodo API to grab the video transcript and metadata (views, chapters, etc.).
Analyze: Google Gemini reads the text and writes a structured summary (overview, takeaways, tools).
Deliver: You receive the formatted summary in chat.

Setup Guide

What You Need

n8n instance (to run the workflow)
Telegram Bot Token (free via @BotFather)
Decodo Scraper API Key (for YouTube data - Get it here)
Google Gemini API Key (for the AI - Get it here)

Quick Installation

Import: Load the JSON file into your n8n instance.
Credentials: Add your API keys for Telegram, Decodo, and Google Gemini in the n8n credentials section.
Configure:
- In the "Alert Admin" node, set the chatId to your Telegram User ID (find it via @userinfobot).
- (Optional) Change the languageCode in the Config node if you want non-English transcripts.
Test: Send a YouTube link to your bot. You should see a "Processing..." message followed by your summary!

Troubleshooting & Tips

"Not a YouTube URL": Make sure you are sending a standard youtube.com or youtu.be link.
No Transcript: The video must have captions (auto-generated or manual) for this to work.
Customization: You can edit the AI Prompt in the "Generate TLDR" node to change how the summary looks (e.g., "Make it funny" or "Focus on technical details").

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.
