The collaborative map for planning trips

You mark the places that interest you on the map —with no date, for when you don't yet know when you're going— and then group them into routes. Giving a route a date is all it takes to turn it into a day of the trip: from there the real route between stops, the distances and the duration are worked out, and you can see whether the day fits.

Google Maps gets you from one place to another, but it doesn't know which day you're going. To plan a multi-day trip you need something that combines map and calendar: seeing where you're going and when, how many kilometres each day, whether it all fits, what's on for Tuesday. Iterare does exactly that: a list of places saved in Google Maps is a pile of points; a trip is an order and some dates.

By connecting your trip to an assistant like Claude or ChatGPT. It reads what you already have —your routes, your places, each day's distances and anything you've written— and answers about it: whether Saturday fits, what's missing, what you're walking past. Ask it for a whole day and it hands it back for you to paste into Iterare: the route is created with its stops in order. The assistant never edits your trip on its own, and it doesn't place the locations either —every stop is looked up on OpenStreetMap and you see it before it exists—, because coordinates recited from memory land believable and wrong.

Each day is a route on the map, so you see where you're going and when at the same time. That lets you answer questions a map full of saved points or a spreadsheet can't: whether one place is near another, how many kilometres that day, whether it all fits, or what to do on Tuesday.

Iterare works out the real route between each day's stops —by road, on foot or by bike— and adds up the distance and the time. It isn't straight-line distance: it's the journey you'd actually make. If a leg can't be calculated, it says so; it never shows an approximate time as if it were exact.

A trip is shared with a link and several people can edit it at once. Everything written is a conversation anchored to a specific spot —a place, a stop, a day— so questions and decisions don't get lost in a group chat: they stay where they matter, and can be marked resolved without deleting them.

Each expense hangs off something in the trip —the whole trip, a place, a stop or a day— so you know not just how much you've spent, but on which part of the trip. The balance between travellers is worked out automatically. You can also log an expense as a forecast, before anyone has paid it, to see what the trip is going to cost.

You can see the forecast at the trip's places, which is exactly what you need to decide whether to reorder the days, bring an outing forward or avoid rain on a mountain route. If there's no reliable forecast for that date, it says so instead of making one up.

Iterare finds the waymarked trails in the area from OpenStreetMap and Waymarked Trails data, and shows their route on the map along with their length. A trail is saved as just another place in the trip, so it joins the day like any other stop and its hours count the same.

Yes, guide mode: a clean, edit-free view with the day's itinerary, its stops, their estimated times and the important information. It's built to check while you travel, when there's nothing left to plan and all you want to know is what's next.
