Turn newsletters into branded LinkedIn carousels
I was shocked that this was possible in the first place. Task: I was shocked that this was possible in the first place. I’ve been posting on LinkedIn 5x a week for the past three months without fail. Before that? Complete mess. On and off for months. The problem wasn’t motivation—I had plenty of that. It was juggling multiple tasks that frustrated me. I’m already writing 3-4 Substack Notes every day plus weekly newsletter posts that take 10+ hours. Adding consistent LinkedIn on top felt impossible. What changed? I built my entire newsletter operating system inside Claude Code. Now Claude Code knows my voice, my performance data, my content archive, my audience patterns. The whole publishing flow became semi-automatic. I write everything with Wisprflow, and it just works. But I kept getting stuck on one thing: carousels. Every time I’d see a well-designed carousel—clean styling, brand guidelines, proper overlay images—I’d bookmark it and think: “Next week, I’ll figure this out.” Next week never came. Because “figuring it out” meant: 1 hour writing the content 1 hour writing the content 1 hour wrestling with Canva 1 hour wrestling with Canva Another 30 minutes fixing alignment and spacing Another 30 minutes fixing alignment and spacing Plus the mental overhead of “does this even look professional?” Plus the mental overhead of “does this even look professional?” So I’d rationalize: “Text and a simple image I pulled from Twitter posts works fine. I’ll stick with what I know.” Hence, I kept avoiding carousels because the effort-to-output ratio felt broken. It was too much. Then I realized something: I’ve been building Claude Skills to automate my entire workflow. Not because I love automation, but because breaking down systems end-to-end teaches me how workflows actually function. It challenges my systems thinking. I told myself, “What if I could build one for carousels?” Not generic templates. Not AI slop that sounds like everyone else. A system that generates carousels in my voice, with my brand, in under 5 minutes—without losing what makes my content authentic. After multiple trials and errors, I finally cracked it. The carousels below? Built in less than 5 minutes each. Still my voice. Still on-brand. Before showing you how it works, let me show you how I got there. Three Failed Attempts at LinkedIn Carousel Automation (And What Finally Worked) I’ve had “build LinkedIn carousel system” on my 2026 goals. But you know how it goes—always busy, never urgent. It sat on my list for months while I prioritized everything else. Then I saw Jonas Braadbaart about building LinkedIn carousels with Claude Code. That was the push I needed. Not because he showed me it was possible—I already knew that. But because seeing someone else solve the exact problem I’d been avoiding made me realize: I have no more excuses. So I finally committed to figuring this out. What I didn’t realize was how many dead ends I’d hit before finding something that actually worked. Attempt #1: Claude Skills PowerPoint Carousel Builder My first instinct was obvious: use Claude Skill to generate carousels in PowerPoint Slides format. I already use Claude Skills for everything else in my workflow, so this felt like the natural path. Anthropic already has PowerPoint slide–builder skills on their GitHub. I copied the skill, ran it, and Claude successfully created the slides. But the output? It’s too plain. There’s no soul, and it leaves too much space unused. It technically works, but it looks generic. What’s great, though, is the speed of generating each slide, it takes me around 3–5 seconds. Insane. Still, I’ve convinced myself this isn’t going to cut it. I need more creativity and aliveness in the slides. Attempt #2: AI Image Generation with Nano Banana Pro If there’s one lesson I took away from the first attempt, it’s that I needed better design quality, so I switched approaches entirely. I studied successful carousel posts from other creators—the ones that actually stopped me from scrolling. I broke them down into components: Logo placement and sizing Logo placement and sizing Header typography and positioning Header typography and positioning Body text hierarchy Body text hierarchy Tag styling and colors Tag styling and colors Brand footer elements Brand footer elements Then I rebuilt these design patterns into a detailed prompt for Nano Banana Pro to generate images that matched my brand. And honestly? The results were stunning.; tools: Claude Code. Human role: The original post does not say how a person stayed involved.; limitations: Requires initial setup of brand guidelines (colors, fonts, logo) in Claude. The workflow depends on Claude's ability to parse newsletter URLs accurately. Manual steps remain for downloading HTML, converting to PDF, and uploading to LinkedIn.

Reported result
The author reports generating carousels in under 5 minutes with consistent branding. However, no quantitative engagement metrics or business outcomes are provided. The success is attributed to the reliability of code-based design versus image generation. A measurable acceptance check would be verifying slide count and brand color accuracy against guidelines.
Human role
The original post does not say how a person stayed involved.
Limitations
Requires initial setup of brand guidelines (colors, fonts, logo) in Claude. The workflow depends on Claude's ability to parse newsletter URLs accurately. Manual steps remain for downloading HTML, converting to PDF, and uploading to LinkedIn. Source reliability is secondary, based on a personal blog post.
Try it
Act as a content automation specialist. I need to create a LinkedIn carousel from [replaceable: newsletter URL or text content]. Use Claude Code to generate HTML/CSS slides based on my brand guidelines: [replaceable: primary color, secondary color, font names, logo file path]. Steps: 1. Analyze the input content and structure it into 6-10 slides (Hook, Content, CTA). 2. Generate HTML/CSS files for each slide, ensuring consistent typography and spacing. 3. Provide the code files for me to review. 4. After my confirmation, guide me on converting these to PDF for LinkedIn upload. Do not publish or send anything without my explicit approval. First, perform a dry run with a sample paragraph to verify design consistency. If the input is a URL, confirm access before proceeding. Output the HTML code blocks clearly.
