26-Year-Old Turns ChatGPT Into $4,000 Monthly Side Hustle

When Dhanvin Sriram discovered ChatGPT in late 2022, the 26-year-old financial analyst saw more than just a powerful tool—he saw a business opportunity. After experimenting with the chatbot, Sriram realized that while ChatGPT was revolutionary, it was only as effective as the prompts users provided. This insight sparked an idea: create a centralized database of effective ChatGPT prompts for different use cases.

Building Momentum With PromptVibes

Sriram launched PromptVibes, a simple website with a minimalist design featuring a fill-in-the-blank search function. Within three to four months, the site attracted 100,000 unique visitors through organic growth, primarily from Reddit and Twitter discussions about AI. The organic traction convinced Sriram that he’d built something genuinely valuable.

Monetizing Through Newsletters and Premium Features

Recognizing the engaged audience, Sriram began publishing a newsletter five times weekly with sponsored ad spots. Once his subscriber base hit 10,000 in August 2026, he consistently earned $2,000-$3,000 monthly from advertising. By reaching 20,000 subscribers, his monthly revenue climbed to $4,000.

Now, Sriram is scaling further with a paid premium version featuring a Chrome plugin for prompt organization. The software will offer three membership tiers ($4.99, $9.99, and $19.99 monthly), with projected revenues of an additional $5,000 monthly if just 3% of subscribers convert.

The success prompted Sriram to leave his full-time position entirely. While building a software business comes with challenges and uncertainties, his ChatGPT-powered side hustle demonstrates that identifying real problems and building simple solutions can create substantial income streams in the AI era.
