How I Made $500 in 30 Days Selling ChatGPT Prompt Libraries

In just 30 days, I went from zero online income to generating over $500—all by creating and selling ChatGPT prompt libraries. These aren’t just random prompts; they’re carefully curated collections designed to help specific audiences—like content creators, solopreneurs, marketers, and business coaches—get better, faster results with AI.

What makes this side hustle so powerful is its simplicity. I didn’t use paid ads, didn’t have a following, and didn’t write a single line of code. Instead, I focused on solving real problems with ready-to-use AI tools packaged for convenience and speed. In this post, I’ll walk you through exactly how I planned, launched, and sold my first prompt packs—and how you can replicate this approach to start earning with AI, too.

What Are Prompt Libraries and Why They Sell

A prompt library is a downloadable collection of pre-tested, high-impact ChatGPT prompts organized by goal, niche, or industry. These libraries work like productivity boosters—offering users ready-made instructions that generate useful, specific, and monetizable outputs from AI without guesswork.

What makes them so appealing is that they eliminate the frustration of writing effective prompts from scratch. Whether you’re a coach, freelancer, entrepreneur, or content creator, a prompt library provides an instant toolkit tailored to your needs.

Here are a few examples of what I created and sold in my first 30 days:

• “25 Instagram Caption Prompts for Coaches” – Designed to generate scroll-stopping content in minutes.
• “The AI Startup Toolkit: 40 Prompts for Product Development” – Ideal for entrepreneurs building MVPs and go-to-market strategies.
• “Freelancer Client Acquisition Prompts” – Scripts for cold emails, proposals, and follow-ups that convert.
• “Etsy Product Listing Generator Pack” – Helps sellers write better SEO-optimized titles and descriptions.

These libraries sold well because they offered clear outcomes, saved users , and could be used to generate real revenue with minimal effort.

How I Created My First Prompt Pack

Building my first prompt product took less than 24 hours, and it followed a simple, repeatable process. Here’s exactly what I did:

1. Picked a Niche: I chose online coaches as my target audience. They’re always looking for ways to boost engagement, attract clients, and stay consistent on social media—making them the perfect group to benefit from plug-and-play AI prompts.
2. Used ChatGPT to Draft Prompts: I asked ChatGPT to generate examples of Instagram hooks, storytelling angles, engagement questions, and CTA formulas that a mindset or business coach might use. The prompt was something like: “Create 10 Instagram caption prompts that help coaches build authority and engagement.”
3. Edited and Grouped: I reviewed the outputs, tested a few, rewrote others, and grouped them into clear categories like:
   • Engagement Boosters
   • Client Testimonials / Case Studies
   • Authority-Building Insights
   • Storytelling and Vulnerability Prompts

   This helped users find what they needed quickly—and made the product feel more polished and professional.

4. Packaged It as a PDF + Notion File: I formatted the final prompts in Google Docs, saved it as a downloadable PDF, and duplicated the content into a Notion template. Offering both formats added perceived value and flexibility—some people prefer printouts, others love digital templates.

By the end of the day, I had a fully functional product ready to sell—complete with a clear niche, tested content, and professional formatting.

Where I Sold My Prompt Libraries

Choosing the right platform to sell your digital products is key to building momentum quickly. Since I didn’t have an existing email list or big social following, I focused on marketplaces that were easy to use and already had built-in traffic. Here’s where I started selling my prompt libraries:

• Gumroad:
  Perfect for beginners. Gumroad is free to start and only takes a small cut of each sale. It lets you set up product pages, deliver downloads automatically, and even run limited-time offers or bundles. I liked how quickly I could get my first listing live, and the ability to customize the checkout experience helped build credibility.
• PromptBase:
  This is a curated marketplace specifically for selling AI prompts. It attracts a niche audience of creators, developers, and entrepreneurs who are already searching for prompt packs. While competition is growing, it’s still early enough to gain traction if your prompts are original and solve real problems.
• Ko-fi:
  Ko-fi combines tipping, memberships, and digital downloads in one place—making it ideal if you want to build community while earning. I found it worked especially well after I started sharing prompt samples and behind-the-scenes posts on social media. It felt more personal and encouraged repeat buyers.

For pricing, I started small—my first pack launched at $9. Once I had three prompt packs available, I bundled them together for $25. That immediately increased my average order value and made the offer feel like a no-brainer for customers.

These platforms handled payment processing, product delivery, and customer emails—all while I focused on creating and promoting more packs. If you’re just getting started, pick one, upload your product, and start testing what resonates.

Tips That Helped Me Reach $500

• Validate Demand: I browsed Reddit, Twitter, and ChatGPT groups to see what people were asking for.
• Make It Visual: I used Canva to design clean, attractive product covers and screenshots.
• Promote Organically: I shared value posts in Facebook groups, on X (Twitter), and in Notion/AI subreddits with links back to my store.
• Add Use Instructions: I included a page on “how to get the best results” to reduce refunds and build trust.

My Tech Stack (All Free or Low-Cost)

You don’t need expensive tools or a complicated setup to launch a profitable digital product. Here’s the simple, budget-friendly tech stack I used to create, design, and sell my ChatGPT prompt libraries:

• ChatGPT: Used to generate, refine, and test all the prompts. It saved hours of brainstorming time and helped me structure high-quality, niche-relevant outputs.
• Canva: Designed all product covers, thumbnails, and promotional graphics. The drag-and-drop interface made it easy to create professional-looking visuals—even with zero design experience.
• Google Docs: Where I wrote, formatted, and organized each prompt library. It’s simple, shareable, and export-ready for PDF packaging.
• Gumroad: My sales platform of choice. It handled product delivery, checkout, and customer emails—all for free to start, with a small percentage taken from each sale.
• Notion: I used Notion to create “live” versions of each prompt pack, which gave customers an editable, web-based experience. It also added extra perceived value alongside the downloadable PDF.

This lean setup kept costs near zero while giving me everything I needed to launch quickly, test new ideas, and scale fast.
