1.1 Workflow description

Title: Generate influencer posts with GPT-4, Google Sheets, and Media APIs
Workflow name: Generate influencer posts with GPT-4, Google Sheets, and Media APIs

This template transforms uploaded brand assets into AI-generated influencer-style posts — complete with captions, images, and videos — using n8n, OpenAI, and your preferred image/video generation APIs.

🧠 Who it’s for

Marketers, creators, or brand teams who want to speed up content ideation and visual generation.
Perfect for social-media teams looking to turn product photos and brand visuals into ready-to-review creative posts.

⚙️ How it works

Upload your brand assets — A form trigger collects up to three files: product, background, and prop.
AI analysis & content creation — An OpenAI LLM analyzes your brand tone and generates post titles, captions, and visual prompts.
Media generation — Connected image/video generation workflows create corresponding visuals.
Result storage — All captions, image URLs, and video URLs are automatically written to a Google Sheet for review or publishing.

🧩 How to set it up

Replace all placeholders in nodes:
- <<YOUR_SHEET_ID>>
- <<FILE_UPLOAD_BASE>>
- <<YOUR_API_KEY>>
- <<YOUR_N8N_DOMAIN>>/form/<<FORM_ID>>
Add your own credentials in:
- Google Sheets
- HTTP Request
- AI/LLM nodes
Execute the workflow or trigger via form.
Check your connected Google Sheet for generated posts and media links.

🛠️ Requirements

Tool	Purpose
OpenAI / compatible LLM key	Caption & idea generation
Image/Video generation API	Creating visuals
Google Sheets credentials	Storing results
(Optional) n8n Cloud / self-hosted	To run the workflow

🧠 Notes

The workflow uses modular sub-workflows for image and video creation; you can connect your own generation nodes.
All credentials and private URLs have been removed.
Works seamlessly with both n8n Cloud and self-hosted setups.
Output is meant for creative inspiration — review before posting publicly.

🧩 Why it’s useful

Speeds up campaign ideation and content creation.
Provides structured, reusable results in Google Sheets.
Fully visual, modular, and customizable for any brand or industry.

🧠 Example Use Cases

Influencer campaign planning
Product launch creatives
E-commerce catalog posts
Fashion, lifestyle, or tech brand content

✅ Security & best practices

No hardcoded keys or credentials included.
All private URLs replaced with placeholders.
Static data removed from the public JSON.
Follows n8n’s template structure, node naming, and sticky-note annotation guidelines.

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.
