Send any raw content to Supermemory — conversations, documents, files, URLs. We extract the memories automatically.

<Tip>
**Use `customId`** to identify your content (conversation ID, document ID, etc.). This enables updates and prevents duplicates.
</Tip>

## Quick Start

<Tabs>
  <Tab title="TypeScript">
    ```typescript
    import Supermemory from 'supermemory';

    const client = new Supermemory();

    // Add text content
    await client.add({
      content: "Machine learning enables computers to learn from data",
      containerTag: "user_123",
      metadata: { category: "ai" }
    });

    // Add a URL (auto-extracted)
    await client.add({
      content: "https://youtube.com/watch?v=dQw4w9WgXcQ",
      containerTag: "user_123"
    });
    ```
  </Tab>
  <Tab title="Python">
    ```python
    from supermemory import Supermemory

    client = Supermemory()

    # Add text content
    client.add(
        content="Machine learning enables computers to learn from data",
        container_tag="user_123",
        metadata={"category": "ai"}
    )

    # Add a URL (auto-extracted)
    client.add(
        content="https://youtube.com/watch?v=dQw4w9WgXcQ",
        container_tag="user_123"
    )
    ```
  </Tab>
  <Tab title="cURL">
    ```bash
    curl -X POST "https://api.supermemory.ai/v3/documents" \
      -H "Authorization: Bearer $SUPERMEMORY_API_KEY" \
      -H "Content-Type: application/json" \
      -d '{
        "content": "Machine learning enables computers to learn from data",
        "containerTag": "user_123",
        "metadata": {"category": "ai"}
      }'
    ```
  </Tab>
</Tabs>

**Response:**
```json
{ "id": "abc123", "status": "queued" }
```

## Updating Content

Use `customId` to update existing documents or conversations. When you send content with the same `customId`, Supermemory intelligently processes only what's new.

### Two ways to update:

**Option 1: Send only the new content**
```typescript
// First request
await client.add({
  content: "user: Hi, I'm Sarah.\nassistant: Nice to meet you!",
  customId: "conv_123",
  containerTag: "user_sarah"
});

// Later: send only new messages
await client.add({
  content: "user: What's the weather?\nassistant: It's sunny today.",
  customId: "conv_123",  // Same ID — Supermemory links them
  containerTag: "user_sarah"
});
```

**Option 2: Send the full updated content**
```typescript
// Supermemory detects the diff and only processes new parts
await client.add({
  content: "user: Hi, I'm Sarah.\nassistant: Nice to meet you!\nuser: What's the weather?\nassistant: It's sunny today.",
  customId: "conv_123",
  containerTag: "user_sarah"
});
```

Both work — choose what fits your architecture.

### Replace entire document

To completely replace a document's content (not append), use `memories.update()`:

```typescript
// Replace the entire document content
await client.documents.update("doc_id_123", {
  content: "Completely new content replacing everything",
  metadata: { version: 2 }
});
```

This triggers full reprocessing of the document. If you only update metadata (no content change), the document is updated in place with no reindexing.

### Formatting conversations

Format your conversations however you want. Supermemory handles any string format:

```typescript
// Simple string
content: "user: Hello\nassistant: Hi there!"

// JSON stringify
content: JSON.stringify(messages)

// Template literal
content: messages.map(m => `${m.role}: ${m.content}`).join('\n')

// Any format — just make it a string
content: formatConversation(messages)
```

## Upload Files

Upload PDFs, images, and documents directly.

<Tabs>
  <Tab title="TypeScript">
    ```typescript
    import fs from 'fs';

    await client.documents.uploadFile({
      file: fs.createReadStream('document.pdf'),
      containerTags: 'user_123'
    });
    ```
  </Tab>
  <Tab title="Python">
    ```python
    with open('document.pdf', 'rb') as file:
        client.documents.upload_file(
            file=file,
            container_tags='user_123'
        )
    ```
  </Tab>
  <Tab title="cURL">
    ```bash
    curl -X POST "https://api.supermemory.ai/v3/documents/file" \
      -H "Authorization: Bearer $SUPERMEMORY_API_KEY" \
      -F "file=@document.pdf" \
      -F "containerTags=user_123"
    ```
  </Tab>

    {
      containerTag: "session_abc123",
      entityContext: `Design exploration conversation between john@acme.com and Brand.ai assistant.
        Focus on John's design preferences and brand requirements.`

## Processing Pipeline

When you add content, Supermemory:

1. **Validates** your request
2. **Stores** the document and queues for processing
3. **Extracts** content (OCR, transcription, web scraping)
4. **Chunks** into searchable memories
5. **Embeds** for vector search
6. **Indexes** for retrieval

Track progress with `GET /v3/documents/{id}`:
```typescript
const doc = await client.documents.get("abc123");
console.log(doc.status); // "queued" | "processing" | "done"
```

<AccordionGroup>
  <Accordion title="Batch Upload">
    Process multiple documents with rate limiting:

    ```typescript
    async function batchUpload(documents: Array<{id: string, content: string}>) {
      const results = [];

      for (const doc of documents) {
        try {
          const result = await client.add({
            content: doc.content,
            customId: doc.id,
            containerTag: "batch_import"
          });
          results.push({ id: doc.id, success: true, docId: result.id });
        } catch (error) {
          results.push({ id: doc.id, success: false, error });
        }

        // Rate limit: 1 second between requests
        await new Promise(r => setTimeout(r, 1000));
      }

      return results;
    }
    ```

    **Tips:**
    - Batch size: 3-5 documents at once
    - Delay: 1-2 seconds between requests
    - Use `customId` to track and deduplicate
  </Accordion>

  <Accordion title="Error Handling">
    | Status | Error | Cause |
    |--------|-------|-------|
    | 400 | BadRequestError | Missing required fields, invalid parameters |
    | 401 | AuthenticationError | Invalid or missing API key |
    | 403 | PermissionDeniedError | Insufficient permissions |
    | 429 | RateLimitError | Too many requests or quota exceeded |
    | 500 | InternalServerError | Processing failure |

    ```typescript
    import { BadRequestError, RateLimitError } from 'supermemory';

    try {
      await client.add({ content: "..." });
    } catch (error) {
      if (error instanceof RateLimitError) {
        // Wait and retry
        await new Promise(r => setTimeout(r, 60000));
      } else if (error instanceof BadRequestError) {
        // Fix request parameters
        console.error("Invalid request:", error.message);
      }
    }
    ```
  </Accordion>

  <Accordion title="Delete Content">
    **Single delete:**
    ```typescript
    await client.documents.delete("doc_id_123");
    ```

    **Bulk delete by IDs:**
    ```typescript
    await client.documents.deleteBulk({
      ids: ["doc_1", "doc_2", "doc_3"]
    });
    ```

    **Bulk delete by container tag:**
    ```typescript
    // Delete all content for a user
    await client.documents.deleteBulk({
      containerTags: ["user_123"]
    });
    ```

    Deletes are permanent — no recovery.
