Frequently Asked Questions

How does SuperLocalMemory compare to cloud AI memory services?

+
SuperLocalMemory stores all data in a local SQLite file on your machine — zero data leaves your device. Cloud services like Mem0 ($99-999/mo) and Zep ($50-500/mo) store your memories on their servers. SuperLocalMemory is free, offline-capable, and integrates natively with 17+ AI tools via MCP. Cloud services offer managed infrastructure and team collaboration features that local-first solutions do not.

Is SuperLocalMemory really free?

+
Yes, completely free and open source under the MIT license. No hidden costs, no freemium tiers, no usage limits. It runs on your hardware, so there are no cloud servers or API infrastructure costs. The local-first architecture eliminates the need for subscription pricing entirely.

Can I migrate from Mem0, Zep, or other services?

+
Yes. SuperLocalMemory uses the MCP protocol and works with 17+ AI tools including Cursor, Claude Desktop, VS Code, Windsurf, ChatGPT, and Gemini CLI. You can start storing new memories locally immediately. The CLI setup takes under 5 minutes with a single npx command, or you can download the desktop app.

Does SuperLocalMemory work offline?

+
Yes. Since all data and processing runs locally (SQLite database + local models), SuperLocalMemory works without any internet connection. This is a fundamental advantage over cloud-based solutions like Mem0, Zep, and Personal.AI, which require constant internet access to function.

When should I choose a cloud solution instead?

+
Cloud solutions are the better choice if you need managed infrastructure for large teams (50+ engineers), SLA guarantees, enterprise compliance certifications, or if you prefer paying for a fully-hosted service rather than running software on your own machine. Mem0 and Zep offer enterprise support tiers that include dedicated account management and custom integrations.

Is SuperLocalMemory better than Mem0?

+
It depends on your needs. SuperLocalMemory is better for privacy (100% local), cost (completely free), and advanced features (lifecycle management, behavioral learning). Mem0 is better if you need cloud sync across multiple machines.

Can I use SuperLocalMemory and Mem0 together?

+
Yes. They serve different purposes and can coexist. Use SuperLocalMemory for local, private memory and Mem0 for cloud-synced team memory.

Does SuperLocalMemory work with Cursor?

+
Yes. SuperLocalMemory has native MCP integration with Cursor. Install and it auto-configures.

Ready to Try the Local Approach?

Your data stays on your machine. No cloud accounts, no API keys, no monthly bills. Just install and start building with persistent AI memory.
