Together

Plan trips and life together — for couples and families.

A shared space for couples and families to plan trips: itineraries, budget, packing lists, restaurant ideas, and dream destinations. Calm, collaborative, mobile-first.

Why this exists

Cozi is a family calendar. Wanderlog is solo-friendly trip planning. TripIt aggregates reservations. None of them are built around the shared trip — both partners contributing, splitting expenses inside the trip, and drafting itineraries together with an AI assistant that knows both people's preferences.

This is also a personal learning project that will be used in real life by me and my partner.

MVP scope (deliberately tiny)

1. Auth + couple/family pairing
2. Create a trip (name, dates, destination, members)
3. Shared trip todo / packing list

Everything else (budget, itinerary days, AI assistant, integrations, dream board) is post-MVP. See docs/FEATURES.md.

Tech stack

• Next.js 16 (App Router, Turbopack) + TypeScript
• Tailwind CSS + Shadcn/ui
• Supabase (Postgres + Auth + RLS) — using supabase-js directly for MVP
• Anthropic Claude for AI features
• Vercel for deployment

Documentation

• VISION — purpose, target users, "why us"
• FEATURES — MVP vs. later
• PLAN — phased roadmap
• DESIGN — visual language
• TECH — stack and rationale
• DECISIONS — non-obvious choices and why
• TODO — current task list

Development approach

• One small task at a time. Validate each increment.
• Root cause before fix. No speculative patches.
• Don't over-engineer — this is a learning project, not a product to scale.
