The Pinterest AI-Machine is an n8n automation template that turns a list of keywords into a continuous stream of SEO-optimised Pinterest pins — complete with AI-generated images and descriptions — published automatically around the clock. You fill in a spreadsheet once, and the system manages your Pinterest account for months without further involvement.

​
What it does

This template combines three tools — ChatGPT, Nano Banano image generation, and the Pinterest API — into a single automated pipeline:
  • Reads keywords from a Google Sheets table you control
  • Generates SEO-optimised titles and descriptions with ChatGPT, written to rank in Pinterest search
  • Creates unique thumbnail images with Nano Banano’s AI image generator — no Canva, no stock photos, no copyright issues
  • Publishes pins to your boards on an automatic timer you configure (for example, every 2 hours)
  • Runs in the cloud — your computer doesn’t need to stay on

​
How it works

1

Import the template and connect your API keys

Download the .json workflow file and import it into your n8n instance. Follow the included instructions to connect your Dohoo API key, OpenAI API key, Nano Banano credentials, and Pinterest account. Everything is documented step by step.
2

Enter post topics into Google Sheets

Open the ready-made Google Sheets template included with your purchase. In the first column, enter the topic for each post — one topic per row. The workflow reads from this sheet each time it runs, so you can add new topics at any time without touching n8n.
3

Set your publishing interval and start

In the n8n trigger node, set how often you want pins to publish — for example, every 2 hours or 3 pins per day. Activate the workflow. From this point, the system generates an image, writes the SEO copy, and publishes the pin automatically on your chosen cadence.

Benefits

Saves 40+ hours per week

What a content manager spends 40 hours a week producing manually, this system delivers in around 10 minutes of your time for initial setup.

AI-generated images avoid copyright issues

Every image is generated fresh by a neural network. There are no stock-photo licensing concerns, and novel visuals get better reach from Pinterest’s algorithm.

SEO-optimised text boosts discoverability

ChatGPT crafts titles and descriptions specifically structured to surface your pins at the top of Pinterest search results for your target keywords.

Scalable across niches

Run one stream or ten. Duplicate the workflow for different keyword sets, boards, or client accounts — the architecture supports any scale.

​
Who it’s for

  • Bloggers and content creators who use Pinterest as a traffic channel and want it running without daily attention
  • E-commerce sellers looking to drive consistent organic traffic to product pages
  • Affiliate marketers managing multiple niche sites who need high-volume pin output without a team
  • Agencies handling Pinterest accounts for multiple clients who need a repeatable, scalable workflow

​
Getting started

1

Purchase the template

Go to dohoo.ai/shop and purchase the Pinterest AI-Machine template for $20.00. Add the Professional Installation option (+$40.00) at checkout if you’d like the Dohoo team to handle setup and configuration for you.
2

Import the workflow into n8n

Download the .json file from your order, open your n8n instance, and go to Workflows → Import from file. Select the file to load the complete workflow.
3

Connect your API credentials

In the workflow, update the credential nodes with your OpenAI API key, Nano Banano credentials, Pinterest API token, and Dohoo API key. All credential fields are labelled in the workflow.
4

Set up your Google Sheet

Make a copy of the included Google Sheets template and share it with your Google service account (credentials required for n8n to read from Sheets). Populate the keyword and board columns with your first batch of content topics.
5

Configure publishing schedule and activate

Set your desired publishing interval in the trigger node, then toggle the workflow to Active. Monitor the first few runs to confirm pins appear on your boards as expected.
A Dohoo Business or Agency plan is required for REST API access. Make sure your Pinterest account is connected in your Dohoo dashboard before activating the workflow.
Start with a small keyword list (10–20 terms) and a moderate cadence (3–5 pins per day) while you validate the content quality. Once you’re happy with the output, scale up by adding more keywords and increasing publishing frequency.
The step-by-step video setup guide is currently in development and not yet available. Until it’s released, follow the written instructions included with your purchase. If you need hands-on help, consider adding the Professional Installation add-on at checkout.
