Create LinkedIn Content with Perplexity Research, GPT-4 & Google Sheets

This n8n workflow automates the process of creating high-quality, scroll-stopping LinkedIn posts based on live research, AI insight generation, and Google Sheets storage.

Instead of relying on recycled AI tips or boring summaries, this system combines real-time trend discovery via Perplexity, structured idea shaping with GPT-4, and content generation tailored to a bold, human LinkedIn voice. The workflow saves each post idea (with image prompt, tone, and summary) to a Google Sheet, sends you a Telegram alert, and even formats your content for direct publishing.

Perfect for solopreneurs, startup marketers, or anyone who posts regularly on LinkedIn and wants to sound original, not robotic.

Who’s it for

• Content creators and solopreneurs building an audience on LinkedIn
• Startup teams, PMs, and tech marketers looking to scale thought leadership
• Anyone tired of generic AI-generated posts and craving structured, edgy output

How it works

• Daily trigger at 6 AM starts the workflow.
• Pulls recent post history from Google Sheets to avoid repeated ideas.
• Perplexity AI scans the web
• Generates 3 structured post ideas (including tone, hook, visual prompt, and summary).
• GPT-4 refines each into a bold, human-style LinkedIn post, following detailed brand voice rules.
• Saves everything to Google Sheets (idea, content, image prompt, post status).
• Sends a Telegram notification to alert you new ideas are ready.

How to set up

• Connect your Perplexity, OpenAI, Google Sheets, and Telegram credentials.
• Point to your preferred Google Sheet and sheet tab for storing post data.

Requirements

• Filter or tag ideas based on type (trend, tip, story, etc.)
• Post automatically via LinkedIn API or Buffer integration
