and rank options. A shared availability calendar surfaces the dates that work for everyone. Budget deal-breakers flag conflicts before anyone books a flight. And a built-in expense splitting tool keeps money from ruining friendships.

Once the group reaches consensus, Atlas takes over. Atlas is Stamp'd's AI travel assistant that generates full day-by-day AI itineraries, custom packing lists, and booking recommendations based on the group's budget, interests, and travel style. Unlike generic itinerary builders, Atlas adapts to the group's preferences over time, learning what kinds of trips, activities, and accommodations each traveler prefers.

The group trip planner covers every phase of travel:

Decide Together: Invite your crew, suggest destinations, vote, and lock in dates and budget. Deal-breaker matching ensures nobody agrees to a trip they can't afford or a destination that doesn't work for them. Whether it's bachelor party planning, a bachelorette trip, or a family vacation, the destination voting system gets groups aligned fast.

Plan Together: Build a shared itinerary with drag-and-drop scheduling, or let the AI itinerary generator create one automatically. Add accommodation options and let the group vote on where to stay. Create shared checklists, upload booking confirmations, and keep everything in one place instead of scattered across email, texts, and Google Docs.

Travel Together: Real-time group chat, shared photo albums, expense tracking with per-item cost splitting, and push notifications keep the group in sync during the trip. The expense splitter handles uneven costs, shared meals, and group activities so nobody has to chase Venmo requests for weeks after the trip.

Remember Together: After the trip, members review and rate the experience. The built-in travel tracker lets users stamp their world map with every country and US state they visit, building a visual travel history. A gamified scoring system tracks travel across four categories: Travel, Social, Diversity, and Commitment, with seven traveler tiers from Uncharted to Legendary.

The Explore tab lets users browse trips and travel stats from the Stamp'd community. Public itineraries can be cloned as trip templates, giving groups a starting point instead of a blank page. Destination guides with budget breakdowns and insider tips help groups pick the right trip for their crew.

Stamp'd solves a specific problem that general-purpose trip planners ignore: group dynamics. When six friends need to pick between Cancun and Barcelona, a shared Google Doc doesn't cut it. When planning a bachelor party for 10 people across three budgets, you need more than a group chat. When a family vacation planner is doing all the work while everyone else just says "I'm down for whatever," the planning process needs structure.

The platform handles group travel planning for friend group vacations, bachelor and bachelorette party planning, family reunion trips, couples group getaways, and any trip where more than two people need to agree on something.

Built on a patent-pending multi-user constraint resolution system with persistent identity feedback that improves future decision generation. In plain terms: the AI travel planner gets better at helping your group decide as you use it more.
