True Cost of Rent reads a rental listing from a screenshot or link and works out what the place really costs each month, including the utilities, fees and commute the listing leaves out. It flags every charge the listing never mentioned and writes the questions to ask before you sign. It is built for first time renters, and across ten real listings the advertised price understated the true cost by 23 percent. Gemini reads and explains, and Python does all the math.
“I wrote a rule telling Gemini not to touch the roommate count on shared listings, and it changed it anyway, which doubled a rent share and made one place look twice as expensive. I found it by testing my own app, and the fix was moving the rule out of the prompt and into code.”
