MemorySync

What is MemorySync?

MemorySync is a hosted memory layer for AI applications. Instead of re-explaining context every session, your agents, coding assistants, and chatbots store facts once and recall the relevant ones later through a simple API. It handles retrieval ranking, memory tiering, and tenant isolation, and plugs into LangChain, CrewAI, Cursor, and Claude Code over MCP.

Top Features:

• Semantic retrieval: hybrid vector search returns relevant memories in under 50 milliseconds.
• Memory tiering: hot, warm, and cold storage keeps frequently used context fast and cheap.
• Enterprise governance: role based access, audit logs, and tenant isolation come built in.

Use Cases:

• Coding assistants: let Cursor or Claude Code remember project decisions across sessions.
• Customer facing agents: keep caller history so voice and chat bots resume past conversations.
• Multi tenant products: give each customer isolated memory without building a vector stack.

Who Can Use MemorySync?

• AI developers: add long term memory to agents with a few lines of code.
• Enterprise platform teams: run governed, auditable memory for many internal AI workloads.
• Workflow builders: use the official n8n and Dify integrations without writing backend code.

Pricing

• Free ($0): 10K add requests and 1K retrieval requests every month.
• Starter ($29 per month): 50K add requests and 5K retrieval requests for small projects.
• Pro ($179 per month): 250K add and 25K retrieval requests, with Scale at $349 monthly.

Pros and Cons

Pros:

• Real free tier: the free plan is enough to prototype an agent before paying.
• Wide integrations: plugins exist for LangChain, LangGraph, CrewAI, LlamaIndex, n8n, and Pipecat.
• Nothing to host: the remote MCP server and API mean no local infrastructure.

Cons:

• Closed source: the core platform is proprietary, so you cannot self host it.
• Request based limits: chatty agents can burn through retrieval quotas faster than expected.
• Young product: the company is new, with few public case studies.

FAQs:

1) Is there a free plan?

Yes, the free tier includes 10K add and 1K retrieval requests each month.

2) Does it work with Cursor and Claude Code?

Yes, a remote MCP server gives both tools persistent memory across sessions.

3) Which SDKs are available?

Official Python and Node.js SDKs plus a plain REST API are provided.

4) Can I isolate memory per customer?

Yes, scopes give each tenant its own cryptographically separated memory.

5) Is it open source?

No, the platform is proprietary, though plugins and starter templates are public.
