This workflow automatically generates realistic comments for your WordPress articles using AI. It makes your blog look more active, improves engagement, and can even support SEO by adding keyword-relevant comments.

How It Works

Fetches all published blog posts from your WordPress site via the REST API.

Builds a tailored AI prompt using the article’s title, excerpt, and content.

Uses OpenAI to generate a short, natural-sounding comment (some positive, some neutral, some longer, some shorter).

Assigns a random commenter name and email.

Posts the generated comment back to WordPress.

Requirements

n8n version: 1.49.0 or later (recommended).
Active OpenAI API key.
WordPress site with REST API enabled.

Translate 🎙️and upload dubbed YouTube videos 📺 using ElevenLabs AI Dubbing

This workflow automates the end-to-end process of **video dubbing** using **ElevenLabs**, storage on Google Drive, and publishing on **Youtube**. This workflow is ideal for creators, agencies, and media teams that need to **TRANSLATE process** and publish large volumes of video content consistently. For this workflow, I started from my [Italian YouTube Short](https://iframe.mediadelivery.net/play/580928/c445daec-e3fe-4019-b035-58ac3bf386dd), and by applying the same workflow, the result was this [English version](https://iframe.mediadelivery.net/play/580928/2179db44-e7e2-43e6-82a1-13b12e18ba8b). --- ### Key Advantages #### 1. ✅ Full Automation of Video Localization The entire process—from video download to AI dubbing and publishing—is automated, eliminating manual steps and reducing human error. #### 2. ✅ Fast Multilingual Content Scaling With AI-powered dubbing, the same video can be quickly localized into different languages, enabling global audience expansion. #### 3. ✅ Efficient Time Management The workflow intelligently waits for the dubbing process to finish using dynamic timing, avoiding unnecessary retries or failures. #### 4. ✅ Centralized Content Distribution A single workflow handles storage, social posting, and YouTube uploads, simplifying content operations across platforms. #### 5. ✅ Reduced Operational Costs Automating dubbing and publishing significantly lowers costs compared to manual voiceovers, video editing, and uploads. #### 6. ✅ Easy Customization & Reusability Parameters like video URL, language, title, and platform can be easily changed, making the workflow reusable for different projects or clients. --- ### **How It Works** 1. The workflow begins with a manual trigger that sets input parameters: a video URL and the target language for dubbing (e.g., `en` for English). 2. The video is fetched from the provided URL via an HTTP request. 3. The video file is sent to the **ElevenLabs Dubbing API**, which initiates audio dubbing in the specified target language. 4. The workflow then waits for a calculated duration (video length + 120 seconds) to allow the dubbing process to complete. 5. After the wait, it checks the dubbing status using the `dubbing_id` and retrieves the final dubbed audio file. 6. The dubbed video is then processed in parallel: - Uploaded to **Google Drive** in a designated folder. - Uploaded to **Postiz** for social media management. - Uploaded via **Upload-Post.com API** for YouTube publishing. 7. Finally, the workflow triggers a **Postiz** node to schedule or publish the content to YouTube with the prepared metadata. --- ### **Set Up Steps** 1. **Configure Input Parameters** In the *Set params* node, define: - `video_url`: Direct URL to the source video. - `target_audio`: Language code (e.g., `en`, `es`, `fr`) for dubbing. 2. **Set Up Credentials** Ensure the following credentials are configured in n8n: - **[ElevenLabs API](https://try.elevenlabs.io/ahkbf00hocnu)** (for dubbing) - **Google Drive OAuth2** (for file upload) - **[Postiz API](https://affiliate.postiz.com/n3witalia)** (for social media scheduling) - **[Upload-Post.com API](https://www.upload-post.com/?linkId=lp_144414&sourceId=n3witalia&tenantId=upload-post-app)** (for YouTube upload) 3. **Adjust Wait Time** Modify the *Wait* node if needed: `expected_duration_sec + 120` ensures enough time for dubbing. Adjust based on video length. 4. **Customize Upload Destinations** Update folder IDs (Google Drive) and platform settings (Upload-Post.com) as needed. 5. **Set Post Content** In the *Youtube Postiz* and *Youtube Upload-Post* nodes, replace `YOUR_CONTENT` and `YOUR_USERNAME` with actual titles, descriptions, and channel details. 6. **Activate and Test** Activate the workflow in n8n, click *Execute workflow*, and monitor execution for errors. Ensure all API keys and permissions are valid. --- 👉 [Subscribe to my new **YouTube channel**](https://youtube.com/@n3witalia).

Create and schedule LinkedIn posts from Google Sheets with Gemini and DALL·E

## Overview This n8n automation is a complete LinkedIn Content Engine that turns simple topic ideas into fully written, visual, and scheduled posts. It features a "Human-in-the-Loop" design, meaning AI handles the heavy lifting of writing and image creation, but nothing goes live until you manually approve it in Google Sheets. ## How It Works The system runs two separate workflows in parallel: ### 1. The "Creator" Workflow **Input:** Detects when you add a new topic to your "Content Calendar" Google Sheet. **Brand Alignment:** Pulls your specific "Brand Voice" guidelines from a separate tab to ensure the AI sounds like you. **Creation:** Uses Gemini Flash 1.5 to write the post and DALL-E 3 to generate a matching professional image. **Drafting:** Uploads the image to ImgBB and saves the full draft back to your sheet with a status of "Draft." ### 2. The "Publisher" Workflow **Daily Scan:** Wakes up every morning to check your Content Calendar. **Verification:** Looks for posts that match two criteria: * Date Scheduled matches today's date. * Status is marked as "Approved" (by you). **Publishing:** If both match, it automatically uploads the text and image to LinkedIn and updates the sheet status to "Posted." **Tools Used:** n8n, Google Sheets, OpenRouter (Gemini / OpenAI), ImgBB. ## Connect & Learn More **YouTube Channel:** **[Simon Scrapes](https://www.youtube.com/@simonscrapes)** – More tutorials on AI & Automation. **Community:** **[Skool Community](https://www.skool.com/scrapes/about)** – Master AI & Automation with us. **Full Video Tutorial:** [Watch the step-by-step build here](https://youtu.be/eiIRSUhPgOI?si=lgZTrPZPMqWF4uqz&t=4276)
