Planning a day trip in China is hard. Every travel blog
gives you a list of attractions but never the optimal order.
Wander China solves this: select your attractions, and
the app uses a nearest-neighbor TSP heuristic to calculate
the shortest walking route with time estimates.
→ 17 cities covered
→ Tourist mode + Expat mode (local spots most visitors miss)
→ No signup, no tracking, runs entirely in the browser

I ran 7 experiments asking 8 different AIs the same investing questions. Their answers kept converging on 4 schools of thought: Index, Value, Growth, and Trend.
So I built a free tool that:
→ Diagnoses your investing school in 5 questions
→ Shows you an AI committee verdict on your fit
→ Gives you a copy-paste Prompt Library tailored to your style
No signup. No paywall. Just the tool.
