Convex apps don't have built-in memory for AI. Supermemory fixes that. You get a memory layer that stores conversations, builds user profiles, and gives your AI context about who it's talking to.

## What you can do

- Store user interactions and retrieve them in future sessions
- Build automatic user profiles from conversations
- Search memories to give your AI relevant context
- Keep everything in your Convex database for full visibility

## Setup

Install the packages:

```bash
npm install supermemory convex
```

For the AI chat example, also install the AI SDK packages:

```bash
npm install @supermemory/tools @ai-sdk/openai ai
```

Set up your environment variable in Convex:

```bash
npx convex env set SUPERMEMORY_API_KEY your-supermemory-api-key
```

<Note>Get your Supermemory API key from [console.supermemory.ai](https://console.supermemory.ai).</Note>

## Basic integration

Create simple helper functions for each Supermemory operation:

```typescript
// convex/memory.ts
import { action } from "./_generated/server";
import { v } from "convex/values";
import { Supermemory } from "supermemory";

const memory = new Supermemory({ apiKey: process.env.SUPERMEMORY_API_KEY });

// Get user profile
export const getProfile = action({
  args: { userId: v.string() },
  handler: async (ctx, { userId }) => {
    return await memory.profile(userId);
  },
});

// Add a memory
export const addMemory = action({
  args: { userId: v.string(), content: v.string() },
  handler: async (ctx, { userId, content }) => {
    return await memory.add(userId, {
      content,
      dreaming: "instant", // memories are ready as soon as status is done
    });
  },
});

// Search memories
export const searchMemories = action({
  args: { userId: v.string(), query: v.string(), limit: v.optional(v.number()) },
  handler: async (ctx, { userId, query, limit }) => {
    return await memory.search(userId, {
      query,
      searchMode: "hybrid",
      limit: limit ?? 10,
    });
  },
});
```

## Example: AI chat with memory

A chat endpoint using the Supermemory AI SDK middleware. It automatically injects context and saves memories.

```typescript
// convex/chat.ts
import { action } from "./_generated/server";
import { v } from "convex/values";
import { generateText } from "ai";
import { openai } from "@ai-sdk/openai";
import { withSupermemory } from "@supermemory/tools/ai-sdk";

export const chat = action({
  args: { userId: v.string(), message: v.string() },
  handler: async (ctx, { userId, message }) => {
    // Wrap the model - automatically injects context and saves memories
    const model = withSupermemory(openai("gpt-4o-mini"), {
      namespace: userId,
      id: `convex-chat-${userId}`,
      mode: "full",
      addMemory: "always",
    });

    const { text } = await generateText({
      model,
      system: "You are a helpful assistant.",
      prompt: message,
    });

    return text;
  },
});
```

## Storing memories in Convex tables

Keep a local copy of memories in your Convex database for full visibility:

```typescript
// convex/schema.ts
import { defineSchema, defineTable } from "convex/server";
import { v } from "convex/values";

export default defineSchema({
  memories: defineTable({
    userId: v.string(),
    content: v.string(),
    createdAt: v.number(),
  }).index("by_user", ["userId"]),
});
```

```typescript
// convex/memory.ts
import { action, mutation, query } from "./_generated/server";
import { api } from "./_generated/api";
import { v } from "convex/values";
import { Supermemory } from "supermemory";

const memory = new Supermemory({ apiKey: process.env.SUPERMEMORY_API_KEY });

// Store in Convex
export const storeMemory = mutation({
  args: { userId: v.string(), content: v.string() },
  handler: async (ctx, { userId, content }) => {
    return await ctx.db.insert("memories", {
      userId,
      content,
      createdAt: Date.now(),
    });
  },
});

// Add memory to both Supermemory and Convex
export const addMemory = action({
  args: { userId: v.string(), content: v.string() },
  handler: async (ctx, { userId, content }) => {
    // Add to Supermemory
    await memory.add(userId, { content });
    
    // Store in Convex
    // Note: in production, handle partial failures — if the Convex mutation
    // fails after the Supermemory write succeeds, the two stores will be out of sync.
    await ctx.runMutation(api.memory.storeMemory, { userId, content });
  },
});

// List memories from Convex
export const listMemories = query({
  args: { userId: v.string() },
  handler: async (ctx, { userId }) => {
    return await ctx.db
      .query("memories")
      .withIndex("by_user", q => q.eq("userId", userId))
      .order("desc")
      .take(50);
  },
});
```
