Zero programming experience, this developer built a million-dollar AI application in a few weeks

Monetization Angle

Develop an AI-powered Excel plugin, built in your spare time with no-code tools, designed to automate spreadsheet tasks, increase the efficiency with which users process data, and monetize through a subscription model.

David, the developer in this case, with zero programming experience, developed an AI application "formulate bot" that is now valued at more than $1 million. He worked just a few hours a day and developed the app in just a few weeks. David mainly learns through YouTube. He successfully launched the product using a viral marketing strategy and attracted thousands of users in just a few days.

Formula Bot is a software that helps people process data faster and smarter, mainly covering AI and spreadsheets, text-to-formula generators, and data analyzers. At the time of the original case report, the app had been around for a year and a half and had about 750,000 users, 5,000 of whom paid for unlimited access, with monthly revenue of about $226,000. YouTube's official site frames the present state this way: The cookie consent dialog discloses that data (including IP address) is used to deliver services, track outages, protect against spam/fraud/abuse and measure audience engagement and site statistics (https://www.youtube.com).

Best For

For entrepreneurs with a non-technical background who have a deep understanding of Excel and want to innovate in the field of data automation.

Creators running this workflow now typically start from Jimeng AI (Dreamina) (https://jimeng.jianying.com) or Midjourney (https://www.midjourney.com).

Difficulty

Moderate. Need to learn to use no-code development tools and be sensitive to the market.

Workflow

Problem identification

Identify problems that are prevalent in everyday work, such as the complexity of Excel formulas.

David found that there was a need to quickly generate Excel formulas at work. He got a suggestion for the name of the app through OpenAI and eventually chose "Excel Formula Bot" as the preliminary name (later renamed "Formula Bot").

Learn No Code Tools:

Take 1-2 weeks to master a no-code tool like Bubble.io.

David can't program at all, but he has completed the core development of the application through bubble.io, a no-code platform. With the accumulation of experience, the proportion of code in the application has gradually increased, from the initial 100% no code to about 5% -10% code now.

Build Minimum Viable Product (MVP):

Quickly build a basic version of an AI tool with no-code tools.

Community Verification:

Share your MVP with relevant online communities, such as Reddit, to get user feedback.

David first showed his colleagues his app and got positive feedback. Subsequently, he posted app information on Reddit and quickly gained a lot of attention.

Product Iterations:

Constantly iterate on products based on user feedback to add new features. Use Reddit, YouTube and other platforms to market and attract users.

OVERCOMING CHALLENGES

With the success of the product, many similar competitors have emerged in the market. David realized that simply providing a simple input-output function was not enough to stand out from the competition. Therefore, he is constantly introducing new features, such as data analyzers, to enhance the competitiveness of the product. At the same time, he is also aware of the potential threats posed by giants such as Microsoft, so his goal is to develop a product that cannot be copied.

Profit Strategy:

Manage the high costs of using AI APIs, deal with market competition, and more. Faced with the high cost of the OpenAI API, David gradually became profitable by accepting donations, running advertisements, and subscribing to services.

Case Review

David's story shows how non-technical entrepreneurs use no-code tools to turn innovative ideas into reality. By observing and solving practical problems, he developed an AI tool using a no-code platform and successfully attracted a large number of users and significant revenue. This story emphasizes that even without coding skills, anyone with the right mindset and perseverance can grow their side project into a thriving business.

Tools Used

No code development platform: Bubble.io.
