Show HN: Free AI trip planner that handles allergies,budgets and group consensus

https://www.rondinello.com
1•yetkinsal•1h ago
Hi HN! I built Rondinello because trip planning was frustrating - whether solo or with friends.

For solo: Tell it your pace, budget, allergies → get a day-by-day itinerary with insider tips.

For groups: Everyone submits preferences, AI finds consensus (handles conflicting budgets, dietary needs, kids, mobility).

Features: - Constraint-first: Allergies, wheelchair access, stroller-friendly - Real place data from Google Places API - Partner deals for hotels, tours, transport - Works for "tonight dinner" or 2-week trips

Tech: Next.js 14, Supabase, OpenAI GPT-5.2

Free, no account needed. Would love feedback!
