Glossary

This page defines each term once. Terms are in alphabetical order.

Term	Definition
Actor	An actor is the person, agent or system that a memory is about. It has an `actor_id` and an `actor_type` of `user`, `agent` or `system`. See Memory scope.
App	An app is a separate memory space. It has its own settings, API keys and memories, and it lives in one region. Its ID looks like `app_...`.
API key	An API key is the secret your code sends to prove it may use an app. It looks like `smrt_<prefix>_<secret>`. The dashboard shows it once.
Conversation	A conversation is a thread of memories that share a `conversation_id`.
Credit	A credit is one unit of quota that a call uses. Memory credits pay for `add`. Search credits pay for `search`, `get` and `delete`. See Limits, quotas and credits.
Data plane	A data plane is the regional service that stores an app's memories and answers its API calls. The dashboard shows it as a region and a cloud, such as `us-east-1 (aws)`. See Regions.
Entity	An entity is a person, place, organization or other thing that Smritea finds in memories. A Deep Search app links entities in a knowledge graph.
Memory	A memory is one stored fact, with its content, scope, metadata and dates. See How Smritea stores memory.
Metadata	Metadata is a set of key and value pairs on a memory. Values are strings, integers or floats. See Filter by metadata.
Ontology	An ontology is an app's list of entity types and relationship types, plus its extraction directives. You edit it in the app wizard.
Participant	A participant is an actor who took part in a conversation. Search uses `participant_ids` to find shared conversations.
Quota	A quota is the credits your plan grants. When it runs out, calls fail with HTTP 402.
Rate limit	A rate limit caps how many calls you can send in a second, a minute or a day. A call over the limit fails with HTTP 429.
Relationship	A relationship is a link between two entities, such as `works for`.
Reranker	A reranker is a step that reorders search results. See Search methods and rerankers.
Scope	A scope is the set of fields that say who a memory is about and where it came from. See Memory scope.
Search method	A search method is the strategy a search uses: `quick_search`, `deep_search` or `context_aware_search`.
Storage engine	The storage engine is an app setting, Quick Search or Deep Search. It decides how `add` turns text into memories. You cannot change it after the app has memories.
Studio	Studio is the Smritea web dashboard and sign-in service. It manages apps, API keys, billing and members.
