Welcome to my AI Social Media Caption Creator Workflow!

What this workflow does

This workflow automatically creates a social media post caption in an editorial plan in Airtable. It also uses background information on the target group, tonality, etc. stored in Airtable.

This workflow has the following sequence:

  1. Airtable trigger (scan for new records every minute)
  2. Wait 1 Minute so the Airtable record creator has time to write the Briefing field
  3. retrieval of Airtable record data
  4. AI Agent to write a caption for a social media post. The agent is instructed to use background information stored in Airtable (such as target group, tonality, etc.) to create the post.
  5. Format the output and assign it to the correct field in Airtable.
  6. Post the caption into Airtable record.

Requirements

  • Airtable Database: Documentation
  • AI API access (e.g. via OpenAI, Anthropic, Google or Ollama)

Example of an editorial plan in Airtable:

AI Social Media Caption Creator for Airtable

This n8n workflow automates the generation of social media captions using AI, directly integrating with Airtable. It listens for new or updated records in a specified Airtable base and table, then uses an AI agent to create engaging captions, and finally updates the Airtable record with the generated content.

What it does

  1. Monitors Airtable: Triggers when new records are created or existing records are updated in a designated Airtable base and table.
  2. Waits (Optional): Includes a configurable wait step, useful for batch processing or allowing time for other processes before AI generation.
  3. Prepares Data: Edits and sets specific fields from the Airtable record, preparing the input for the AI agent.
  4. Generates Captions with AI: Utilizes an AI Agent (powered by an OpenAI Chat Model and Simple Memory) to generate social media captions based on the provided Airtable data.
  5. Updates Airtable: Takes the AI-generated caption and updates the original Airtable record with this new content.

Prerequisites/Requirements

  • n8n Instance: A running instance of n8n.
  • Airtable Account: An Airtable account with a base and table set up for your social media posts.
  • Airtable API Key: An API key for Airtable to allow n8n to connect.
  • OpenAI API Key: An API key for OpenAI to power the AI Chat Model.

Setup/Usage

  1. Import the Workflow: Import the provided JSON workflow into your n8n instance.
  2. Configure Airtable Trigger:
    • Select your Airtable credential.
    • Specify the Base ID and Table Name you want to monitor.
    • Choose the Trigger When option (e.g., "Record Created" or "Record Updated").
  3. Configure AI Agent:
    • OpenAI Chat Model: Select your OpenAI credential.
    • Simple Memory: This node manages the conversation context for the AI agent. No specific configuration is usually needed beyond its presence.
    • The AI Agent will need to be configured with a prompt that guides it on how to generate captions based on the input data from Airtable.
  4. Configure Airtable Update Node:
    • Select the same Airtable credential.
    • Specify the Base ID and Table Name.
    • Map the ID of the record from the trigger to ensure the correct record is updated.
    • Map the output of the AI Agent (the generated caption) to the desired field in your Airtable table (e.g., a "Caption" field).
  5. Activate the Workflow: Once configured, activate the workflow to start monitoring your Airtable table.

The workflow will now automatically generate and update social media captions in Airtable whenever a new record is created or an existing one is updated, streamlining your content creation process.

Automate Dutch Public Procurement Data Collection with TenderNed

TenderNed Public Procurement What This Workflow Does This workflow automates the collection of public procurement data from TenderNed (the official Dutch tender platform). It: Fetches the latest tender publications from the TenderNed API Retrieves detailed information in both XML and JSON formats for each tender Parses and extracts key information like organization names, titles, descriptions, and reference numbers Filters results based on your custom criteria Stores the data in a database for easy querying and analysis Setup Instructions This template comes with sticky notes providing step-by-step instructions in Dutch and various query options you can customize. Prerequisites TenderNed API Access - Register at TenderNed for API credentials Configuration Steps Set up TenderNed credentials: Add HTTP Basic Auth credentials with your TenderNed API username and password Apply these credentials to the three HTTP Request nodes: "Tenderned Publicaties" "Haal XML Details" "Haal JSON Details" Customize filters: Modify the "Filter op ..." node to match your specific requirements Examples: specific organizations, contract values, regions, etc. How It Works Step 1: Trigger The workflow can be triggered either manually for testing or automatically on a daily schedule. Step 2: Fetch Publications Makes an API call to TenderNed to retrieve a list of recent publications (up to 100 per request). Step 3: Process & Split Extracts the tender array from the response and splits it into individual items for processing. Step 4: Fetch Details For each tender, the workflow makes two parallel API calls: XML endpoint - Retrieves the complete tender documentation in XML format JSON endpoint - Fetches metadata including reference numbers and keywords Step 5: Parse & Merge Parses the XML data and merges it with the JSON metadata and batch information into a single data structure. Step 6: Extract Fields Maps the raw API data to clean, structured fields including: Publication ID and date Organization name Tender title and description Reference numbers (kenmerk, TED number) Step 7: Filter Applies your custom filter criteria to focus on relevant tenders only. Step 8: Store Inserts the processed data into your database for storage and future analysis. Customization Tips Modify API Parameters In the "Tenderned Publicaties" node, you can adjust: offset: Starting position for pagination size: Number of results per request (max 100) Add query parameters for date ranges, status filters, etc. Add More Fields Extend the "Splits Alle Velden" node to extract additional fields from the XML/JSON data, such as: Contract value estimates Deadline dates CPV codes (procurement classification) Contact information Integrate Notifications Add a Slack, Email, or Discord node after the filter to get notified about new matching tenders. Incremental Updates Modify the workflow to only fetch new tenders by: Storing the last execution timestamp Adding date filters to the API query Only processing publications newer than the last run Troubleshooting No data returned? Verify your TenderNed API credentials are correct Check that you have setup youre filter proper Need help setting this up or interested in a complete tender analysis solution?

Auto-reply & create Linear tickets from Gmail with GPT-5, gotoHuman & human review

This workflow automatically classifies every new email from your linked mailbox, drafts a personalized reply, and creates Linear tickets for bugs or feature requests. It uses a human-in-the-loop with gotoHuman and continuously improves itself by learning from approved examples. How it works The workflow triggers on every new email from your linked mailbox. Self-learning Email Classifier: an AI model categorizes the email into defined categories (e.g., Bug Report, Feature Request, Sales Opportunity, etc.). It fetches previously approved classification examples from gotoHuman to refine decisions. Self-learning Email Writer: the AI drafts a reply to the email. It learns over time by using previously approved replies from gotoHuman, with per-classification context to tailor tone and style (e.g., different style for sales vs. bug reports). Human Review in gotoHuman: review the classification and the drafted reply. Drafts can be edited or retried. Approved values are used to train the self-learning agents. Send approved Reply: the approved response is sent as a reply to the email thread. Create ticket: if the classification is Bug or Feature Request, a ticket is created by another AI agent in Linear. Human Review in gotoHuman: How to set up Most importantly, install the gotoHuman node before importing this template! (Just add the node to a blank canvas before importing) Set up credentials for gotoHuman, OpenAI, your email provider (e.g. Gmail), and Linear. In gotoHuman, select and create the pre-built review template "Support email agent" or import the ID: 6fzuCJlFYJtlu9mGYcVT. Select this template in the gotoHuman node. In the "gotoHuman: Fetch approved examples" http nodes you need to add your formId. It is the ID of the review template that you just created/imported in gotoHuman. Requirements gotoHuman (human supervision, memory for self-learning) OpenAI (classification, drafting) Gmail or your preferred email provider (for email trigger+replies) Linear (ticketing) How to customize Expand or refine the categories used by the classifier. Update the prompt to reflect your own taxonomy. Filter fetched training data from gotoHuman by reviewer so the writer adapts to their personalized tone and preferences. Add more context to the AI email writer (calendar events, FAQs, product docs) to improve reply quality.
