Artifacts

Artifacts are interactive, versioned documents that AI agents can create, modify, and share. They enable rich AI experiences beyond simple chat by producing persistent outputs like code, documents, diagrams, and data visualizations.

New in v0.33.0

The Artifacts API was introduced in v0.33.0. For complete API documentation, see Artifacts Operations.

What Are Artifacts?

Artifacts differ from memories in a fundamental way:

Memories store conversation context and facts for retrieval
Artifacts store interactive documents for display and collaboration

Think of artifacts as the "canvas" where AI agents produce their creative outputs:

Code Files

Source code with syntax highlighting and streaming generation

Documents

Markdown, prose, and formatted text content

Data Sheets

Tabular data in JSON array format

Diagrams

Mermaid, SVG, and visual diagrams

HTML/React

Interactive previews and components

Custom Types

Define your own artifact kinds

Key Capabilities

Version Control with Undo/Redo

Every change to an artifact creates a new version. Users can navigate through history just like a document editor:

// Make changes
await cortex.artifacts.update(artifactId, "version 2 content");
await cortex.artifacts.update(artifactId, "version 3 content");

// Undo to previous version
const undone = await cortex.artifacts.undo(artifactId);
console.log(undone.currentVersion); // 2

// Redo to restore
const redone = await cortex.artifacts.redo(artifactId);
console.log(redone.currentVersion); // 3

// Get full history
const history = await cortex.artifacts.getHistory(artifactId);
// [{ version: 1, content: "...", timestamp: ... }, ...]

Streaming Content Generation

Artifacts support real-time streaming for AI-generated content. This is essential for code generation, document writing, and any content that takes time to produce:

Streaming State Lifecycle

Draft

Initial state when created

Streaming

Receiving content chunks from AI

Paused

Temporarily stopped (resumable)

Final

Completed and versioned

Artifacts move through well-defined states during streaming

// Start streaming session
const { sessionId } = await cortex.artifacts.startStreaming({
  artifactId: artifact.artifactId,
});

// Append content chunks
for await (const chunk of aiGeneratedContent) {
  await cortex.artifacts.appendContent({
    artifactId: artifact.artifactId,
    sessionId,
    chunk,
  });
}

// Finalize when done
await cortex.artifacts.finalizeStreaming({
  artifactId: artifact.artifactId,
  sessionId,
  changeSummary: "AI-generated code completion",
});

Multi-Tenancy Support

Like all Cortex APIs, artifacts support multi-tenant isolation out of the box:

// Artifacts are isolated by tenant
const artifact = await cortex.artifacts.create({
  memorySpaceId: "user-123-workspace",
  title: "Customer Report",
  content: "# Q4 Report\n...",
  kind: "text",
  // tenantId is auto-injected from auth context
});

File Attachments

Artifacts can have binary files attached via Convex storage:

// Upload a file
const result = await cortex.artifacts.uploadFile({
  artifactId: artifact.artifactId,
  file: imageBlob,
  filename: "diagram.png",
  mimeType: "image/png",
});

// Get file URL for display
const url = await cortex.artifacts.getFileUrl(artifact.artifactId);

Artifact Kinds

Each artifact has a kind that determines how it should be rendered and edited:

Kind	Description	Use Case
`text`	Plain text, markdown, prose	Documents, notes, reports
`code`	Source code with language	Code generation, snippets
`sheet`	Tabular data (JSON array)	Spreadsheets, data tables
`image`	Image reference	Generated images, diagrams
`diagram`	Mermaid, SVG, or similar	Architecture diagrams, flowcharts
`html`	HTML/React for preview	Interactive components
`custom`	User-defined types	Domain-specific artifacts

// Code artifact with language config
const codeArtifact = await cortex.artifacts.create({
  memorySpaceId: "workspace",
  title: "API Handler",
  content: "export function handler(req, res) { ... }",
  kind: "code",
  kindConfig: { language: "typescript" },
  tags: ["api", "handler"],
});

// Sheet artifact
const sheetArtifact = await cortex.artifacts.create({
  memorySpaceId: "workspace",
  title: "User Data",
  content: JSON.stringify([
    { name: "Alice", role: "Admin" },
    { name: "Bob", role: "User" },
  ]),
  kind: "sheet",
});

TypeScript SDK

import { Cortex } from "@cortexmemory/sdk";

const cortex = new Cortex({ convexUrl: process.env.CONVEX_URL! });

// Create an artifact
const artifact = await cortex.artifacts.create({
  memorySpaceId: "user-workspace",
  title: "Meeting Notes",
  content: "# Team Standup\n\n- Discussed roadmap...",
  kind: "text",
  tags: ["meetings", "team"],
});

// Update content (creates new version)
await cortex.artifacts.update(artifact.artifactId, "# Updated Notes\n...", {
  changeSummary: "Added action items",
});

// List artifacts
const artifacts = await cortex.artifacts.list({
  memorySpaceId: "user-workspace",
  kind: "text",
  sortBy: "updatedAt",
  sortOrder: "desc",
});

Python SDK

from cortex import Cortex, CreateArtifactOptions

cortex = Cortex(convex_url=os.environ["CONVEX_URL"])

# Create an artifact
artifact = await cortex.artifacts.create(
    CreateArtifactOptions(
        memory_space_id="user-workspace",
        title="Data Analysis",
        content="# Results\n\nThe analysis shows...",
        kind="text",
        tags=["analysis", "q4"],
    )
)

# Streaming example
result = await cortex.artifacts.start_streaming(
    StartStreamingParams(artifact_id=artifact.artifact_id)
)

for chunk in ai_generated_content:
    await cortex.artifacts.append_content(
        AppendContentParams(
            artifact_id=artifact.artifact_id,
            session_id=result.session_id,
            chunk=chunk,
        )
    )

await cortex.artifacts.finalize_streaming(
    FinalizeStreamingParams(
        artifact_id=artifact.artifact_id,
        session_id=result.session_id,
    )
)

Vercel AI SDK Integration

The Vercel AI Provider includes tools for AI-driven artifact management:

import { createArtifactTools } from "@cortexmemory/vercel-ai-provider";
import { streamText } from "ai";

// Create tools for AI to use
const artifactTools = createArtifactTools({
  storage: cortex.artifacts,
  writer: dataStreamWriter,
});

// Use with streamText
const result = streamText({
  model: openai("gpt-4o"),
  messages,
  tools: {
    ...artifactTools,
  },
});

React hooks for artifact state management:

import { useArtifacts, useArtifact } from "@cortexmemory/vercel-ai-provider/react";

function ArtifactPanel() {
  const { artifactList, activeArtifact, handleDataPart } = useArtifacts();

  return (
    <div>
      {artifactList.map((artifact) => (
        <ArtifactCard key={artifact.artifactId} artifact={artifact} />
      ))}
      {activeArtifact && <ArtifactEditor artifact={activeArtifact} />}
    </div>
  );
}

When to Use Artifacts vs Memories

Use Artifacts When	Use Memories When
User needs to see/edit the content	Content is context for AI
Content is a "deliverable" (code, docs)	Content is conversation history
Undo/redo is needed	Semantic search is needed
Streaming generation is required	Fact extraction is needed
Binary files are involved	Long-term recall is the goal
