At it's core, supermemory is powered by a custom learning model and a graph database that we built internally.

<CardGroup cols={2}>
  <Card title="Learning model">
    Decides what and how to learn, what is important, when to forget, creating relations, etc.
  </Card>
  <Card title="Temporal Vector-graph engine">
    Where the learnings are actually stored, optimized for search. Fact-based temporal graph that has Vector, FTS, and graph built in.
  </Card>
</CardGroup>

But, you don't have to think about the above. The interface for users is as simple as it gets.

from supermemory import Supermemory

client = Supermemory(api_key="sm_...")  # from console.supermemory.ai → API Keys

client.add(content="The user loves Paris.", container_tag="user_123")

results = client.search(
    q="where does the user want to travel?",
    container_tag="user_123",
)

  -d '{
    "content": "The user loves Paris.",
    "containerTag": "user_123"
  }'
```
</CodeGroup>

## What you send: documents

A **document** is raw input — whatever you hand Supermemory:

- Conversation transcripts and messages
- Text, markdown, HTML
- PDFs, images, audio/video, code
- URLs and connector items (Drive, Notion, Gmail, …)

You do not pre-chunk or pick an embedding model. See [Multi-modal ingestion](/concepts/content-types) for formats, and [Add context](/ingestion/add-memories) for the API.

Supermemory handles the ingestion and extraction for you. This also gives us a big advantage for quality - The engine extracts it in an optimized way with Contextual Chunking and other features for better quality search and memory generation.

> Use a stable **`customId`** when the same conversation or file will be updated later (sessions, connector syncs). That identity also drives [diff billing](/overview/billing#full-discount-on-already-seen-tokens-diff-billing) on re-ingest.

## What the pipeline does

| Stage | What happens |
| --- | --- |
| **Queued** | Accepted; waiting to run |
| **Extracting** | Text / OCR / transcription / page fetch |
| **Chunking** | Splits content for retrieval (type-aware where needed) |
| **Embedding** | Vectors for similarity search |
| **Indexing** | Makes chunks and derived structure searchable |
| **Done** | Document path is ready for search |

```typescript
const doc = await client.add({
  content: conversationText,
  containerTag: "user_123",
  customId: "chat_session_1",
});

// Poll until ready
const status = await client.documents.get(doc.id);
// status.status → "queued" | "extracting" | ... | "done" | "failed"
```

Larger PDFs and long video take longer. Short chat turns usually finish in seconds.

## Dreaming (how memories enter the graph)

Document **status `done`** means chunks are indexed for search. **Memories** — the graph facts, updates, and derives — come from a second phase called **dreaming**.

This is when the content is passed through the memory model and merged, arranged and organized for the future.

Pass `dreaming` on [add](/ingestion/add-memories):

| Mode | Default? | Behavior | When to use |
| --- | --- | --- | --- |
| **`dynamic`** | Yes | Related documents are grouped so memories form from **coherent units**, not one isolated write at a time. Graph quality is higher for real multi-turn / multi-doc flows. Memory extraction may continue **after** `status: "done"`. | Production agents, connectors, ongoing sessions |
| **`instant`** | No | This document is dreamed **on its own, right away**. Memories are available as soon as processing finishes for that doc. Bills **one extra [operation](/overview/billing)** per document. | Demos, quickstarts, “I need the graph now” |

```typescript
// Production default — omit or set explicitly
await client.add({
  content: conversationText,
  containerTag: "user_123",
  customId: "chat_session_1",
  dreaming: "dynamic",
});

// Need memories immediately (e.g. tutorial)
await client.add({
  content: conversationText,
  containerTag: "user_123",
  customId: "chat_session_1",
  dreaming: "instant",
});
```

**Rule of thumb:** prefer **`dynamic`** for quality and cost in real apps, use **`instant`** when the next step is a memory search or profile that must reflect this document immediately (as in the [quickstart](/quickstart)). Keeping it dynamic helps it pair better with other memories and better connections, inferences to be made.

How those memories connect and stay true over time is [Graph memory](/concepts/graph-memory). API detail: [Processing modes](/ingestion/add-memories#processing-modes).

## What you get out

After the pipeline runs, the same document leads to three things -> Chunks, Memories and Profile. (in the same `containerTag`):

| Output | Role | Go deeper |
| --- | --- | --- |
| **Document chunks** | Grounding in the raw source (RAG / SuperRAG) | [SuperRAG](/concepts/super-rag), [Search API](/recall/search) |
| **Memories** | Extracted facts in a living graph — updates, links, time | [Graph memory](/concepts/graph-memory) |
| **Profile** | A sample of memories, static + dynamic summary for always-on context | [Profiles](/concepts/user-profiles), [Profile API](/recall/user-profiles) |

Supermemory does **not** only store the file. It derives **memories** (understanding) and keeps **chunks** (the source) so you can personalize *and* ground. That distinction is the core of [Memory vs RAG](/concepts/memory-vs-rag).

## Isolation and identity

- **`containerTag`** — hard isolation boundary (user, tenant, project). See [Container tags](/concepts/container-tags).
- **Metadata** — soft dimensions *inside* a tag for filtering. See [Metadata filtering](/concepts/filtering).
- **Scoped API keys** — credentials that cannot cross a container. See [API keys](/authentication#scoped-api-keys).
