Supermemory automatically extracts and indexes content from various formats. Just send it—we handle the rest. See Add Memories to learn how to ingest content via the API.
Text Content
Raw text, conversations, notes, or any string content.
await client.add({
content: "User prefers dark mode and uses vim keybindings",
containerTags: ["user_123"]
});
URLs & Web Pages
Send a URL and Supermemory fetches, extracts, and indexes the content.
await client.add({
content: "https://docs.example.com/api-reference",
containerTags: ["documentation"]
});
Documents
PDF
await client.add({
content: pdfBase64,
contentType: "pdf",
title: "Q4 Financial Report"
});
Microsoft Office
| Format | Extension | Content Type |
|---|
| Word | .docx | docx |
| Excel | .xlsx | xlsx |
| PowerPoint | .pptx | pptx |
await client.add({
content: docxBase64,
contentType: "docx",
title: "Product Roadmap"
});
Google Workspace
Automatically handled via Google Drive connector:
- Google Docs
- Google Sheets
- Google Slides
Code & Markdown
// Markdown
await client.add({
content: markdownContent,
contentType: "md",
title: "README.md"
});
// Code files (auto-detected language)
await client.add({
content: codeContent,
contentType: "code",
metadata: { language: "typescript" }
});
Images
await client.add({
content: imageBase64,
contentType: "image",
title: "Architecture Diagram"
});
Audio & Video
// Audio
await client.add({
content: audioBase64,
contentType: "audio",
title: "Customer Call Recording"
});
// Video
await client.add({
content: videoBase64,
contentType: "video",
title: "Product Demo"
});
Structured Data
JSON
await client.add({
content: JSON.stringify(userData),
contentType: "json",
title: "User Profile Data"
});
CSV
await client.add({
content: csvContent,
contentType: "csv",
title: "Sales Data Q4"
});
File Upload
For binary files, encode as base64:
import { readFileSync } from 'fs';
const file = readFileSync('./document.pdf');
const base64 = file.toString('base64');
await client.add({
content: base64,
contentType: "pdf",
title: "document.pdf"
});
Auto-Detection
If you don’t specify contentType, Supermemory auto-detects:
// URL detected automatically
await client.add({ content: "https://example.com/page" });
// Plain text detected automatically
await client.add({ content: "User said they prefer email contact" });
For binary content (files), always specify contentType for reliable processing.
Content Limits
| Type | Max Size |
|---|
| Text | 1MB |
| Files | 50MB |
| URLs | Fetched content up to 10MB |
For large files, consider chunking or using connectors for automatic sync.
