This workflow is a experiment to build HTML pages from a user input using the new Structured Output from OpenAI. How it works: Users add what they want to build as a query parameter The OpenAI node generate an interface following a structured output defined in the body The JSON output is then converted to HTML along with a title The HTML is encapsulated in an HTML node (where the Tailwind css script is added) The HTML is rendered to the user via the Webhook response. Set up steps Create an OpenAI API Key Create the OpenAI credentials Use the credentials for both nodes HTTP Request (as Predefined Credential type) and OpenAI Activate your workflow Once active, go to the production URL and add what you'd like to build as the parameter "query" Example: https://production_url.com?query=a%20signup%20form Example of generated page

Scrape and summarize webpages with AI
This workflow integrates both web scraping and NLP functionalities. It uses HTML parsing to extract links, HTTP requests to fetch essay content, and AI-based summarization using GPT-4o. It's an excellent example of an end-to-end automated task that is not only efficient but also provides real value by summarizing valuable content. Note that to use this template, you need to be on n8n version 1.50.0 or later.
Create Instagram carousels and TikTok slideshows with OpenAI and PostFast
Quick overview This workflow runs on a Mon/Wed/Fri schedule to generate an Instagram carousel or TikTok slideshow using OpenAI (GPT-4o-mini and gpt-image-1), sends the slides to Telegram for approval, and only then uploads the images and schedules the post via PostFast. How it works Runs every Monday, Wednesday, and Friday at 8am and loads your brand, topics, slide count, platform filter, and Telegram chat ID. Retrieves your connected social accounts from PostFast and keeps only accounts that are connected and match the selected platforms. Uses OpenAI (gpt-4o-mini) to write a carousel as strict JSON containing a caption and slide-by-slide headings, body text, and visual descriptions. Builds per-slide image prompts and uses OpenAI (gpt-image-1) to generate a 1024×1536 portrait image for each slide. Sends the generated slide images to Telegram and waits for you to approve or decline posting. If approved, requests per-account upload URLs from PostFast, uploads each slide image to the provided storage URLs, and schedules one PostFast social post per account with the slides in order and the generated caption. Setup Install and enable the PostFast community node (n8n-nodes-postfast) and
Create Zoho Books invoices from email attachments using OpenAI OCR
Quick overview This workflow monitors an IMAP inbox for emails with invoice attachments, uses OpenAI to OCR and extract structured invoice data, looks up customers and tax/currency settings in Zoho Books, and then creates a new Zoho Books invoice with the original attachment included. How it works Triggers when a new email arrives via IMAP. Filters for emails that contain attachments, then splits each attachment into its own item for processing. Normalizes each attachment’s binary data and routes it to OpenAI for OCR based on whether it is a PDF or an image. Fetches taxes, currencies, and active customer contacts from Zoho Books and prepares the data for matching and invoice creation. Sends the OCR text plus Zoho Books tax metadata to OpenAI to validate that the document is a sales invoice and to return invoice and customer details as JSON. Filters out non-invoice attachments, matches the extracted customer to an existing Zoho Books contact (with a configurable fallback), and posts a new invoice to Zoho Books using multipart upload to attach the original file. Setup Add IMAP credentials for the mailbox that receives invoice emails. Add Zoho Books OAuth2 credentials and ensure the c
