Iter is a travel planning app that learns a traveler's preferences from visual choices and conversation, and turns them into a day by day itinerary the traveler can edit.

It opens with photos, short clips and a few quick questions. A traveler's responses establish an initial Taste Profile: preferred pace, the kinds of places that appeal, how they like to spend a day. The profile is refined by later choices and conversations, including distinctions within an interest; a traveler can enjoy museums and prefer one a day.

Planning begins with a destination, a budget, a feeling, or nothing more than a date. Iter responds with suggestions shown as images, drawn from the Taste Profile and the current conversation. The traveler keeps or passes on each one, asks for alternatives, or changes direction, and the itinerary forms through that exchange. Iter's working principle: Iter proposes, the traveler decides.

The result is a day by day itinerary in which every stop can be replaced, reordered, removed, or supplemented, including a hotel the traveler has already booked. A change affects only the stop that was changed; the rest of the itinerary stays exactly as the traveler left it. Hotel and flight options come from travel provider partners and are booked with the provider.

Between trips, Home surfaces places and experiences that fit the profile, together with a smaller number that deliberately sit outside it, for travelers to save toward a future trip. Iter also plans day trips: from a traveler's home region, it proposes a single day, planned and editable the same way as a longer trip.

Iter is developed by Iter Travel App LLC, an independently funded company in New York founded by Valentin Lieu. It is available on the App Store and Google Play and free to download and use; the release that introduces the Taste Profile, visual planning and editable itineraries arrives 1 November 2026.
