- “Their productivity has jumped 30-40%. For $50-100 a month, that's a no-brainer ROI.” — Jan
The problem
Building Teacher AI — software to solve the "not enough speaking practice" problem for language learners — requires real development capacity, and developer time is the expensive bottleneck in shipping an app.
The AI solution
The development team building Teacher AI adopted Cursor, an AI coding tool, as their day-to-day development environment. The developers use it while building the actual product rather than as an occasional helper, and the productivity gain was measured across the team.
The economics are the point: at $50-100 per month per seat against a 30-40% jump in developer output, it's a no-brainer ROI. The same session paired this with the non-coder version of the idea — "vibe-coding" with ChatGPT, where a member built interactive lead magnets for his language courses just by describing what he wanted, refining ("not this, not that, make it mobile-optimized"), previewing in ChatGPT, and dropping the code into a WordPress block or iframe instead of paying a developer thousands.
Tools & costs
Results
Developer productivity jumped 30-40% for $50-100 a month per seat; separately, a member shipped functional interactive lead magnets with zero code, avoiding thousands in developer fees.
How to copy it
- If you have developers, get them Cursor and have them use it as their main coding environment.
- Track output before and after to confirm the ROI.
- If you can't code, describe the quiz or game you want to ChatGPT and iterate: "not this, not that, make it mobile-optimized."
- Preview in ChatGPT but always test on your actual site.
- Embed the final code in a WordPress block or iframe.
