How Memori Works

Memori gives your AI application long-term memory. Instead of forgetting everything after each conversation, your AI can remember facts, preferences, and context across sessions and across different applications.

Attribution

Every memory in Memori is tagged with three dimensions: who (entity), what (process), and which conversation (session).

• Entity (entity_id) — The person, place, or thing generating memories. Typically a user ID (e.g., "user_alice", "company_acme").
• Process (process_id) — The agent, program, or workflow creating memories (e.g., "support_bot", "code_review_agent").
• Session (session_id) — Groups related LLM interactions into a conversation thread. Auto-generated as a UUID by default.

The combination of entity_id + process_id + session_id creates a unique memory scope — different users have isolated memories, the same user can have different context in different applications, and each conversation is tracked separately.

from memori import Memori
from openai import OpenAI

client = OpenAI()
mem = Memori().llm.register(client)

# Set attribution before any LLM calls
mem.attribution(
    entity_id="user_alice",
    process_id="support_bot"
)
# session_id is auto-generated

response = client.chat.completions.create(
    model="gpt-4o-mini",
    messages=[
        {"role": "user", "content": "I prefer dark mode."}
    ]
)

Memory Types

When you have a conversation through a Memori-wrapped LLM client, Advanced Augmentation extracts structured memories in the background:

How Recall Works

Recall brings stored memories back into your AI conversations. There are two modes.

Automatic Recall (Default)

On every LLM call, Memori automatically:

1. Intercepts the outbound request
2. Uses semantic search to find relevant facts for the current entity
3. Injects the most relevant memories into the system prompt
4. Forwards the enriched request to the LLM

No extra code required — it happens transparently.

Manual Recall

Use mem.recall() to retrieve memories explicitly — useful for building custom prompts, displaying memories in a UI, or debugging.

from memori import Memori

mem = Memori()
mem.attribution(entity_id="user_alice", process_id="support_bot")

facts = mem.recall("coding preferences", limit=5)

for fact in facts:
    print(f"Fact: {fact.content}")
    print(f"Score: {fact.similarity:.4f}")

Each returned fact includes id, content, similarity (0–1 relevance score), rank_score, and date_created.

Recall Configuration

Memori uses semantic search (vector similarity) to find relevant facts. You can tune recall behavior with:

# Example: tune recall for broader or narrower results
mem.config.recall_relevance_threshold = 0.05  # Lower = more results
mem.config.recall_embeddings_limit = 500      # Reduce for lower memory usage

Memory Lifecycle

1. Conversation — Your user talks to your AI through the wrapped LLM client
2. Capture — Memori intercepts and stores the raw conversation
3. Augmentation — Advanced Augmentation processes the conversation asynchronously, extracting structured memories
4. Extraction — Facts, preferences, skills, and attributes are identified
5. Storage — Extracted memories are stored in Memori Cloud with vector embeddings
6. Recall — On the next LLM call, relevant memories are retrieved and injected into context
