Category & Scope

Tools & Capabilities Breakdown

Iai Personal Memory Engine Tools (9)

memory_recall

Cue-based recall — returns hits **and anti-hits**: memories that *contradict* the cue surface next to the ones that match, so a stale fact can't masquerade as current.

memory_temporal_recall

Time-anchored recall — *"what did I say about pricing in May?"*

memory_recall_structural

Retrieve by the *shape* of a memory (the HD substrate), not just its embedding.

memory_search

Plain text search over the store.

memory_capture

Write a memory explicitly (ambient capture normally does this for you).
