Frequently Asked Questions
What is an ekko?
An ekko is a memory search. Your AI sends an ekko into the memory substrate and retrieves the relevant patterns, episodes, and solutions.
What is a crystallization?
A crystallization is a permanent insight. Use it when you know: "We must never lose this decision again."
How does collective memory work?
Pro users can access anonymized, generalized patterns learned across all ekkOS_™ users. No raw code or proprietary data is ever shared.
Can I export my data?
Yes, at any time.
Which IDEs are supported?
Cursor, VS Code, Claude Code, Windsurf, and any MCP-compatible tool.
Can I self-host?
Yes — enterprise customers can deploy ekkOS_™ privately.
