Show HN: AI-powered meetup planner that optimizes for fair travel times

https://www.midway.at
1•KApilmittal•3h ago
"I got tired of the endless group chat debate about where to meet, especially when someone always ended up with a terrible commute while others walked 5 minutes.

So I built Midway@ - an AI that finds meeting spots where everyone's travel time is actually fair. Not just geographic midpoints (which are often terrible), but real optimization for travel time equity.

*How it works:* - Enter everyone's starting location + transport method (car/transit/walk/bike) - Describe what you want ('coffee shop with WiFi', 'restaurant with parking') - AI analyzes thousands of venues using live traffic/transit data - Returns spots where commute times are balanced

*Technical details:* - Google Maps APIs for real-time travel calculations - Custom algorithm that minimizes travel time variance across the group - Handles mixed transport modes (some drive, others take transit) - Venue ranking considers both travel equity and suitability match

*Interesting data from 10,000+ groups:* - 67% of manually chosen meetup spots have >15min travel time imbalance - Geographic center is optimal location only 23% of the time - Groups save average 47 minutes of coordination time

Built with Next.js, deployed on Vercel. Would love feedback on the algorithm or UX improvements!
