Tern

Tern began as an AI travel planner that generated personalized, day-by-day itineraries from a short description of your interests, budget and dates. Rather than dumping a list of links on you, it structured a realistic trip: what to do each morning and afternoon, how far apart things are, and which reservations need to happen first. Travelers in more than 100 countries used it to plan city breaks, road trips and multi-stop vacations.

The product has since been rebuilt. Visiting travelwithtern.com now redirects to heytilly.ai, where the same team ships Tilly, an AI concierge that spans restaurants, local events and travel rather than trips alone. In the current roadmap, Tern is explicitly listed as the travel layer being integrated into Tilly: the itinerary logic and destination knowledge carry over, while the surrounding experience widens to everyday planning, group coordination and actual booking.

Because Tern is now a component of a larger invite-only product, the practical way to use it today is to join the Tilly waitlist. The free tier of the original Tern planner is not separately purchasable, and the site does not publish standalone pricing. If you need a travel planner right now and cannot wait for access, treat Tern as a rebranded product in transition rather than a standalone service with its own sign-up.
