The chat panel is wired directly into your itinerary. It can move, add, swap, or delete activities — and check whether the resulting schedule actually works given travel times. A few patterns get you dramatically better results.
The AI re-reads the full itinerary on every turn, so it always knows the current state. What it needs from you is the intent — what you want different, and why.
Every activity and transport has a #N badge on the left. Use that number when asking for a change — it eliminates ambiguity when two activities share a name (two dinners, two flights, etc.).
If you do refer to an activity by name (or you skip the number), add the day. The AI requires a day_index to delete or replace a row — without it the request is rejected as ambiguous.
The AI plans better when you give it a reason. "Make Day 3 cheaper" gets a $30 lunch swap. "We blew the morning budget already" gets the AI to drop a paid activity and free-time the afternoon.
Budget, energy level, weather, group composition, dietary, mobility — anything that should shape the answer. State it up front so the AI plans around it.
Asking the AI to choose between two concrete things is faster than asking it to brainstorm. "Pick between sushi at A and yakitori at B" trims it to one decision.
The AI shines at the planning grammar — sequencing, conflicts, day pacing, day-trips out and back. Generic facts ("what time does the Louvre open?") are better Google searches; the AI can use them but won't replace authoritative sources for hours/prices.
You can swap Day 3 in one message instead of patching it activity-by-activity. The AI applies all the changes in one validated batch.
Routing data is wired in. The AI will catch trips where two activities are too far apart for the scheduled window. You can also ask it to flag risks before you commit.
These keep responses fast and on-topic. Limmello stays inside itinerary planning.
Visas, insurance, vaccinations, SIM cards, currency exchange, packing lists, etiquette — out of scope. The AI will politely steer you back to the itinerary.
Once an activity is marked Booked, the AI won't silently change or delete it. It will refuse and ask you to unmark Booked first if you really want to swap it.
Day-trips are fine, but the AI won't add days or extend the trip. To change start/end dates, use the pencil icon next to the trip title.
The AI can READ expense splits — so asking "how much did I spend on this trip so far including what others owe me?" works. It will NOT create, edit, or settle splits for you. Use the 🔀 Split button on a receipt to allocate, and the Split balance tab to mark debts paid.
Free plan: 20 AI messages per trip (lifetime). Pro plan: 100 messages/month across all trips. The onboarding 10-question setup doesn't count toward either limit.
After you publish a trip, reshaping more than 50% of its activities locks the trip until you spend a trip credit. Metadata (title, dates, budget, currency, countries) stays editable.
