Supermemory is the memory and context layer for AI. #1 on LongMemEval, LoCoMo, and ConvoMem — the three major benchmarks for AI memory.
We are a research lab building the engine, plugins and tools around it.
Your AI forgets everything between conversations. Supermemory fixes that.
It automatically learns from conversations, extracts facts, builds user profiles, handles knowledge updates and contradictions, forgets expired information, and delivers the right context at the right time. Full RAG, connectors, file processing — the entire context stack, one system.
🧠 Memory
Extracts facts from conversations. Handles temporal changes, contradictions, and automatic forgetting.
👤 User Profiles
Auto-maintained user context — stable facts + recent activity. One call, ~50ms.
🔍 Hybrid Search
RAG + Memory in a single query. Knowledge base docs and personalized context together.
🔌 Connectors
Google Drive · Gmail · Notion · OneDrive · GitHub — auto-sync with real-time webhooks.
📄 Multi-modal Extractors
PDFs, images (OCR), videos (transcription), code (AST-aware chunking). Upload and it works.
All of this is in our single memory structure and ontology.
Use Supermemory
🧑💻 I use AI tools
Give Claude Code, Cursor, Codex and OpenCode persistent memory across every conversation with a plugin or the MCP server.
Your AI remembers your preferences, projects, past discussions — and gets smarter over time.
If you're building AI agents or apps, Supermemory gives you the entire context stack through one API — memory, RAG, user profiles, connectors, and file processing.
import Supermemory from "supermemory";
const client = new Supermemory();
// Store a conversation
await client.add({
content: "User loves TypeScript and prefers functional patterns",
containerTag: "user_123",
});
// Get user profile + relevant memories in one call
const { profile, searchResults } = await client.profile({
containerTag: "user_123",
q: "What programming style does the user prefer?",
});
// profile.static → ["Loves TypeScript", "Prefers functional patterns"]
// profile.dynamic → ["Working on API integration"]
// searchResults → Relevant memories ranked by similarity
from supermemory import Supermemory
client = Supermemory()
client.add(
content="User loves TypeScript and prefers functional patterns",
container_tag="user_123"
)
result = client.profile(container_tag="user_123", q="programming style")
print(result.profile.static) # Long-term facts
print(result.profile.dynamic) # Recent context
Supermemory automatically extracts memories, builds user profiles, and returns relevant context. No embedding pipelines, no vector DB config, no chunking strategies.
Framework integrations
Drop-in wrappers for every major AI framework:
// Vercel AI SDK
import { withSupermemory } from "@supermemory/tools/ai-sdk";
const model = withSupermemory(openai("gpt-4o"), { containerTag: "user_123", customId: "conv-1" });
// Mastra
import { withSupermemory } from "@supermemory/tools/mastra";
const agent = new Agent(withSupermemory(config, "user-123", { mode: "full" }));
State-of-the-art memory, on your machine. One binary. Zero config.
curl -fsSL https://supermemory.ai/install | bash
# or
npx supermemory local
supermemory-server
First boot sets up the embedded Supermemory graph engine, local embeddings, and your credentials, then prints an API key. The full Memory API — documents, memories, user profiles, hybrid search — runs against http://localhost:6767.
const client = new Supermemory({
apiKey: "sm_...",
baseURL: "http://localhost:6767", // that's the only change
});
Bring any model — OpenAI, Anthropic, Gemini, Groq, or any OpenAI-compatible endpoint. An interactive wizard walks you through it on first boot.
Embeddings — local Xenova/bge-base-en-v1.5 by default (no API key); optionally OpenAI, Gemini, or Ollama. Same provider stack as cloud.
Fully offline if you want — point it at Ollama (gpt-oss:20b works great) and nothing leaves your machine.
Your data, one directory — everything lives in ./.supermemory, easy to back up or move.
Same API as the platform — prototype locally, ship on the hosted platform by changing baseURL.
On LongMemEval, supermemory reaches 95% Recall@15 while adding only ~720 tokens of context — a 99.4% context reduction (99.6% at @10, 99.8% at @5). Recall by category: Knowledge Updates 99%, Assistant recall 100%, User recall 97%, Multi-session 93%, Temporal Reasoning 91%, Preference 90%.
We also built the Supermemory Filesystem (SMFS), which uses 3.0× fewer tokens on Claude (24M vs 72M) and 1.75× fewer on Codex across the 110-question xAFS benchmark. See the full write-ups on our research page.
We also built MemoryBench — an open-source framework for standardized, reproducible benchmarks of memory providers. Compare Supermemory, Mem0, Zep, and others head-to-head:
bun run src/index.ts run -p supermemory -b longmemeval -j gpt-4o -r my-run
Benchmarking your own memory solution
We provide an Agent skill for companies to benchmark their own context and memory solutions against supermemory.
npx skills add supermemoryai/memorybench
Simply run this and do /benchmark-context - Supermemory will automatically do the work for you!

Memory is not RAG. RAG retrieves document chunks — stateless, same results for everyone. Memory extracts and tracks facts about users over time. It understands that "I just moved to SF" supersedes "I live in NYC." Supermemory runs both together by default, so you get knowledge base retrieval and personalized context in every query.

Automatic forgetting. Supermemory knows when memories become irrelevant. Temporary facts ("I have an exam tomorrow") expire after the date passes. Contradictions are resolved automatically. Noise never becomes permanent memory.
Supermemory 是一个面向 AI 的记忆和上下文引擎：它会从你的对话中学习，提取事实并构建用户画像，让你的 AI 在多次会话之间记住你，而不是每次都从零开始。
