Automatically generate visual presentations with n8n, GPT-5, and Gamma

Quick Overview

This demonstration outlines a full-stack content research, writing, and designing automation workflow using n8n, GPT-5, and Gamma to create visually engaging LinkedIn Carousels automatically based on user input for topic and audience. The workflow executes sequential steps including web research via Tavily, data aggregation, narrative drafting via a Storyteller Agent, content creation via Gamma's API, and final compilation into a referenceable format saved to a spreadsheet.

Key Points: The entire process is orchestrated through an n8n workflow designed for full-stack content automation, covering research, writing, and design. The workflow begins by taking the topic ("AI Agent Research Insights and Findings an archive for October 2025") and audience ("AI Devs") from an initial form submission. Web research is performed using the Tavily tool, followed by splitting, editing, and aggregating the retrieved information. A Storyteller Agent, powered by GPT-5, drafts a cohesive narrative based on the aggregated research, adhering to a specific instruction set for style (e.g., LinkedIn Carousel style). The drafted narrative is passed to the 'Create Content with Gamma' node, which uses Gamma's API (requiring an API key) to generate a presentation with visuals and slides. After content generation, the workflow retrieves a URL for the presentation, waits for completion, and finally appends the Gamma URL and reference information to a Google Sheet for final compilation and reference. The resulting Gamma presentation is highly visual, featuring content like 'October's AI Agent Revolution' and 'Evaluations Finally Grew Up' slides, demonstrating the automated design capability.

Context: The video serves as a tutorial demonstrating how to build an advanced automation pipeline using the workflow automation tool n8n to fully automate the creation of rich media content, specifically LinkedIn Carousels. This process integrates several cutting-edge AI capabilities, notably leveraging the advanced language model GPT-5 for narrative structuring and the presentation tool Gamma for visual output, all tied together with custom logic and external services like Tavily for research and Google Sheets for output logging.
