List accumulation and reminder triggering

A system, comprising a processor and a computer-readable medium coupled to the processor, the computer-readable medium having instructions stored thereon, which, when executed by the processor, cause the processor to perform operations comprising:

• generating a plurality of reminder lists, comprising:
• generating a first reminder for a first reminder list based on first user input specifying at least a first item that belongs to a first reminder category associated with the first reminder list, the generated first reminder identifying the first item;
• generating a second reminder for a second reminder list based on second user input specifying at least a second item that belongs to a second reminder category associated with the second reminder list, the generated second reminder identifying the second item,
• wherein the second reminder category is different from the first reminder category;
• clustering the first reminder from the first reminder list and the second reminder from the second reminder list based on the first reminder category and the second reminder category belonging to a particular category cluster;
• receiving a user request that identifies the particular category cluster;
• determining that the first reminder and the second reminder are responsive to the user request that identifies the particular category cluster based on the first reminder category and the second reminder category belonging to the particular category cluster;
• and
• causing the first reminder and the second reminder to be presented in response to receiving the user request that identifies the particular category cluster.

A non-transitory computer-readable medium having instructions stored thereon, which, when executed by a processor, cause the processor to perform operations, comprising:
