How to Add Persistent Memory to Your App with Supermemory

Supermemory is a memory layer for AI apps: you send it text, links or files, and it stores them so your app can recall relevant context later. It exposes a REST API and SDKs, handles the chunking and embeddings, and returns the pieces that matter for a query. Think of it as a hosted memory backend instead of a vector store you assemble yourself.

It fits chatbots, assistants and CRM-style tools where a user expects the product to remember them. The API is small enough to wire up in an afternoon, and there is a free tier for development. Sign up, grab a key, and you can store your first memory in minutes.

What is Supermemory?

Supermemory is a managed memory API. You organize data into containers or namespaces per user, add content, and search it with natural language. It returns relevant memories with metadata, so your model gets grounded context rather than a blank slate each session.

How do you get started?

1. Create an account and copy your API key.
2. Install the SDK or call the REST endpoint directly.
3. Create a container/namespace per user (e.g. user-42).
4. Add a memory: paste text, or pass a URL or file.
5. Search the namespace and inject the results into your prompt.

Namespaces keep one user’s memories from leaking into another’s results.

What can you store?

• Plain text notes and conversation snippets.
• URLs it fetches and parses.
• Uploaded files like PDFs and docs.

Files and pages get chunked automatically, so you do not manage splitting by hand.

How do you retrieve memories?

Send a query string and the namespace; get back the closest memories with scores and metadata. A common pattern is to fetch the top few before each model call and prepend them as context. Keep the count small — injecting 20 memories dilutes the answer more than it enriches it.

Is Supermemory free?

There is a free tier for building and testing, with usage limits on stored items and API calls. Paid plans raise the limits and add team features. Exact numbers shift, so check the current pricing page before you build a cost model around it. For prototypes, the free tier is usually enough.

What are the trade-offs?

You are sending user data to a third party, which matters if you handle sensitive content — check the data policy and whether you need self-hosting. Retrieval quality depends on what you store: garbage in, garbage recalled. And memory is not a substitute for a database; use it for fuzzy recall, keep hard facts in your own store.

Key Takeaways

• Supermemory is a hosted memory API for storing and recalling context.
• Organize data into a namespace or container per user.
• Accepts text, URLs and files; chunks content automatically.
• Free tier exists for development; paid plans raise limits.
• Popular for chatbots and assistants; keep hard facts in your own DB.
