From rate con to fuel plan in seconds.

Setup: The driver opens a private chat with the bot from the truck group and answers three questions — language, driver type, navigation app. Fuel stops arrive there from then on.

SetupThree taps in the driver’s own chat. Once ever.

Pick a stop: For every load the bot asks when the driver wants to fuel, offers the two best reachable stations with the fuel-card price, and locks in the pick with a tap-to-copy address and one-tap navigation.

Pick a stopButtons only show what the tank can reach.

Ask anything: Drivers text the bot in plain words and their own language — cheapest diesel on the route, weather ahead, how far to delivery. Anything the bot cannot answer with confidence goes to dispatch.

Ask anythingPlain words, 8 languages. Unsure → dispatch.

The truck chat: Add the bot to the truck’s group: it links the truck from the chat name and sends the driver to his own fuel chat. Dispatch drops the rate confirmation; the bot confirms the load in one line and anyone can @mention it for engine, position, ETA and delivery status.
