Supported Content Types

All the content formats Supermemory can ingest and process

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"]
});

Best for: Chat messages, user preferences, notes, logs, transcripts.

---

URLs & Web Pages

Send a URL and Supermemory fetches, extracts, and indexes the content.

await client.add({
  content: "
  containerTags: ["documentation"]
});

Extracts: Article text, headings, metadata. Strips navigation, ads, boilerplate.

---

Documents

PDF

await client.add({
  content: pdfBase64,
  contentType: "pdf",
  title: "Q4 Financial Report"
});

Extracts: Text, tables, headers. OCR for scanned documents.

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" }
});

Extracts: Structure, headings, code blocks with syntax awareness.

Code is chunked using code-chunk, which understands AST boundaries to keep functions, classes, and logical blocks intact. See Super RAG for how Supermemory optimizes chunking for each content type.

---

Images

await client.add({
  content: imageBase64,
  contentType: "image",
  title: "Architecture Diagram"
});

Extracts: OCR text, visual descriptions, diagram interpretations.

Supported: PNG, JPG, JPEG, WebP, GIF

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

  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: " });

// Plain text detected automatically
await client.add({ content: "User said they prefer email contact" });

INFO

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

TIP

For large files, consider chunking or using connectors for automatic sync.
