Build a niche industry app by talking to Grok Bot about your own codebase

@johnsonjeremiah (Oct 15) says they built a full app on the way home from the doctor's office just by talking to Grok Bot, then reviewed the working app online at home. They say it is a very niche app, built on their entire GitHub codebase and 26 years in their industry, and the first time they built something without holding the whole build in their own head.
Try it yourself
What you get
A working first version of a niche app, built from your codebase and what you know about your field.
Tools
- Grok Bot (voice)
- GitHub
Steps
- Connect your GitHub codebase so the bot works from your real code.
- Talk the app through by voice: who it is for and the industry rules you know.
- Let the bot hold the plan and build it.
- Review and test the working app yourself before anyone else uses it.
Copy-ready prompt
Read my GitHub repo [REPO]. I want an app for [WHO] in [INDUSTRY] that does [JOB]. Ask me questions about how the work really happens, keep the full plan for me, build it on top of my existing code and send me a link to test when it runs.
Watch out: If you are driving, keep it to hands-free voice and do not look at or test the app until you have stopped. Review the code and data handling before real customers use it.

In their words
I built a full app today on the way home from the doctor's office, just by talking to @Grok @Bot.
