Frequently Asked Questions
What happens to my memories on the Free plan?
Memories stay active for 30 days, then move to cold archive for 90 more days. Nothing is deleted right away — upgrade to Pro anytime and your full history is restored instantly.
Is "unlimited" really unlimited?
Yes, for human use. Fair-use limits apply to automated abuse patterns (see our Terms of Service). Technical storage caps are listed in Compare Plans.
Can I switch plans later?
Yes. Upgrade or downgrade anytime from your dashboard billing page. Changes take effect immediately for upgrades; downgrades apply at the end of your billing period.
How is API usage metered?
Each MCP tool call and REST API request counts toward your daily limit. View real-time usage on your dashboard Usage page.
What happens when I hit a limit?
You receive a fair-use or storage limit notice from MCP or API. Upgrade to Pro for permanent memory or Team for expanded shared storage.
Do I need Memxus if my AI already has memory?
No. Memxus is the persistence layer. You connect via MCP (Claude Desktop, Cursor), Custom GPT Actions (ChatGPT), or embed `@aimemory/sdk` in your stack.
Ready for persistent memory?
Connect MCP or a Custom GPT in minutes, or embed `@aimemory/sdk` for full control.
