How to Build an Automated Content Pipeline with n8n + ElevenLabs + Gamma

Build an Automated Content Pipeline with n8n, ElevenLabs, and Gamma

In this tutorial, you will build a fully automated content pipeline that takes a blog post idea, writes the content, converts it to a professional presentation, and generates an audio version, all without manual intervention. We will use n8n for workflow automation, ElevenLabs for text-to-speech, and Gamma for AI-powered presentations.

This pipeline is designed for content teams that need to produce multi-format content at scale. A single trigger produces a written article, a slide deck for distribution on LinkedIn and internal meetings, and an audio narration for podcast feeds or embedded players. What used to require three people and two days now happens in under 15 minutes.

You will need accounts on all three platforms, plus a basic understanding of REST APIs. No coding experience is required since n8n handles all the integration logic visually.

Step-by-Step Setup

• Step 1: Set up n8n either self-hosted via Docker or on n8n Cloud. Create a new workflow and add a webhook trigger node that will receive content briefs as JSON payloads with a topic, target audience, and desired tone.
• Step 2: Add an HTTP Request node that sends the content brief to your preferred AI writing API such as OpenAI or Anthropic to generate a full blog article. Configure the prompt to include your brand voice guidelines and desired word count.
• Step 3: Add a second HTTP Request node that sends the generated article to the Gamma API to create a presentation. Gamma accepts markdown content and returns a styled slide deck. Configure the template ID to match your brand theme.
• Step 4: Add a third HTTP Request node that sends the article text to the ElevenLabs API using your preferred voice ID. Use the text-to-speech endpoint with the Turbo v3 model for fastest generation.
• Step 5: Add output nodes to store the results. Use Google Drive or S3 nodes to save the audio file, presentation link, and article text. Add a Slack or email notification node to alert the team when the pipeline completes.
• Step 6: Test the full pipeline by sending a sample brief to your webhook URL. Verify that all three outputs are generated correctly and stored in the right locations.

Configuration Tips

Error handling is critical for production pipelines. Add error trigger nodes in n8n that send Slack alerts if any API call fails. Set retry logic on each HTTP Request node with a maximum of 3 attempts and exponential backoff. This prevents a temporary API outage from silently breaking your content schedule.

For content quality, add a review checkpoint between the article generation and distribution steps. You can use n8n Wait node to pause the workflow and send a preview email to an editor, then resume the pipeline when they approve via a webhook callback. This adds a human quality gate without sacrificing the automation benefits for the production and distribution steps.

Our Verdict

This three-tool pipeline demonstrates the power of connecting specialized AI tools through automation. n8n provides the orchestration layer, ElevenLabs delivers studio-quality audio, and Gamma creates visually compelling presentations. The total cost is approximately $50 per month for moderate volume, which is a fraction of what manual production would cost. Start with this foundation and extend it with additional nodes for social media posting, SEO optimization, or analytics tracking as your content operation scales.
