Vehicle sharing service optimization (e.g., using a computerized tool) is enabled. For example, a system can comprise a memory that stores computer executable components, and a processor that executes the computer executable components stored in the memory, wherein the computer executable components comprise: an intent grouping component that, using a defined intent grouping algorithm, groups intents of a user into an intent group, wherein the intents comprise respective requests to schedule an appointment to use a vehicle, a demand component that, based on the intents of the intent group and using a defined demand algorithm, determines a demand of the user, wherein the demand comprises one or more parameters representative of a need, of the user, for the vehicle, and an output component that generates an output representative of the demand.
