Wikipedia-powered 20 Questions with AI that actually knows the cards.

Strengths

•Dynamic Wikipedia database means infinite topics, not a fixed question tree like Akinator
•Groq + prompt caching shows real cost optimization for AI game economics
•Custom boards and daily puzzles create replay value beyond one-off novelty

Weaknesses

•Game novelty - unclear if players return after the initial curiosity wears off
•AI consistency risks on edge cases could break the deduction logic

Post Description

I haven't seen anything like this so I decided to build it in a weekend.

How it works: You see a bunch of things pulled from Wikipedia displayed on cards. You ask yes or no questions to figure out which card is the secret article. The AI model has access to the image and wiki text and it's own knowledge to answer your question.

Happy to have my credits burned for the day but I'll probably have to make this paid at some point so enjoy. I found it's not easy to get cheap+fast+good responses but the tech is getting there. Most of the prompts are running through Groq infra or hitting a cache keyed by a normalization of the prompt.
