A marketer who is not a developer built a local-language AI calorie tracker with Cursor that he says makes over $80K a month

Tomer brought the CalAI idea to the Israeli market in Hebrew and grew it with paid ads where ad prices are lower.

Case Overview & Background

Tomer came from marketing and had only a little coding experience. He saw that a popular AI calorie tracking app did not exist in his local language, so he built one for that market. Like CalAI, the user takes a picture of a meal and gets calories and macros in seconds, but the app is in Hebrew and adjusted for local users.

How AI Is Used

AI is both the feature and the builder. The app estimates calories and macros from a photo, and he says that after two weeks with Cursor he had a working version; he now uses Claude for coding and AI agents across the business.

Step-by-Step Process

Step 01Spot a proven app missing locally

He chose a popular US app idea that had no local version.

Step 02Build with AI prompting

He had a working version after two weeks with Cursor.

Step 03Use the cheapest channel

He found paid ads profitable because local ad prices are lower than in the US.

Customer Acquisition & Distribution

Paid ads, which he says are profitable in his market because CPMs are much lower than in the US.

Limitations, Risks & Failure Modes

What may not apply to you, and what could go wrong:

  • The figures are self-reported and were not independently checked
  • Large global apps can add local language support
  • Paid ads tie growth to ad costs

Key Takeaways

  • Localizing a proven AI app can be a fast route to revenue
  • Marketing skill can matter more than coding skill when AI writes the code
