Osi doesn't dump a generic itinerary on you. Converses step by step: transport, accommodation, activities. Compares options with up-to-date data and asks what you prefer before moving on. See how it compares costs.
During the trip, Osi adapts in real time. Museum closed? Nearby alternatives. Running late? Adjusts the rest of the day. Emergency: nearest hospital and embassy at a tap. All from Telegram. What it does during the trip.
Osi learns your preferences, saves ideas from Instagram or friends for later, and remembers important dates. Every trip starts with an edge because Osi already knows you.
You can ask any LLM to draft an itinerary. What you can't ask is for it to remember you, to learn your travel style, or to be there when the museum closes unexpectedly.

|---|---|---|
| Memory | Forgets you the moment you close the chat | Remembers every trip you've taken |
| Personalization | Same generic itinerary for everyone | Calibrated to your pace, style, and budget |
| Real data | Doesn't know the market closes at 2pm | Verifies real hours with Google Maps |
| During the trip | Stops working when you close the chat | Pings you proactively during the trip |
| Learning | Learns zero from each trip you take | Every trip makes it better at the next one |
| Real time | Can't tell you if the cable car is worth it today | Checks weather and prices in real time |

"An LLM answers you. Osi knows you, travels with you, and learns."
Commands and modes that extend Osi beyond conversation: planning, on-the-trip, and everyday urban use. All available right now on Telegram.
Seven days before departure, Osi sends a curated checklist for your destination: visa, vaccines, electrical plug, currency, local apps, 14-day weather, and logistics — all as a downloadable HTML. No more scrambling through 12 tabs the night before.
Invite your partner, friend, or family as ORGANIZER (can edit) or COMPANION (read-only). Share the plan, the reservations, and the decisions. Ideal for couples' trips without re-explaining the itinerary three times.
While you travel, Osi pings you proactively: between 30 and 90 minutes before each booked activity, alerts if the weather shifts, alternatives if a place is closed. You don't have to write to it — it writes to you.
Osi also works in your home city. Search restaurants/cafes/places nearby and A→B routes. Your travel agent is now also your local agent.
Send a link from Instagram, TikTok, Google Maps, or just the name — Osi extracts the destination and category and saves it. When you start planning that trip, it remembers and surfaces it at the right moment.
Each member keeps their own Traveler DNA, memories, and trips — fully isolated. The family plan supports the owner plus up to 5 additional profiles (6 in total) under one subscription. Built for parents planning for in-laws, kids, and themselves.
Search for @theplan_travel_bot and type /start. Osi asks a few questions to learn your travel style.
"I want to go to Tequila in September for my aunt's birthday." Osi understands context, not just destinations.
Day-by-day itinerary with real places, prices in your currency, transport comparisons, and recommendations based on your profile.
During the trip, check today's plan, ask for changes in real time, log reservations, and have emergency info one message away.
Back home, Osi asks what worked and what didn't. Your answers improve your traveler profile — the next trip starts with an edge.
The Plan is a personal AI travel agent that works on the web and on Telegram. Unlike other assistants, The Plan compares transport options with real numbers, builds day-by-day itineraries with specific places and prices, and adapts in real time during your trip.
The Plan has a free plan with 10 messages per day — enough to plan a short trip. Paid plans offer unlimited messages, memory across sessions, and more advanced AI models for transport analysis and complex reasoning.
Osi analyzes each option (rental car, train, bus, flight) with costs broken down per person, door-to-door times including transfers, and gives a clear recommendation with numerical reasoning. For example, from Strasbourg to Interlaken on a 10-day trip: full car €1,351, trains only €242 and mixed €703 (the recommended one), which saves about €650 versus the full car.
The Plan automatically detects your language from your first message. It works in Spanish and English. If you ask for another language, Osi tells you it only serves those two for now.
Osi becomes your real-time guide: shows today's plan (/today), suggests alternatives if a place is closed, adjusts the itinerary if you're running late, and with /emergency you get the nearest hospital and embassy instantly.
