What is EverOS?
EverOS is a long-term memory runtime for AI agents designed to help agents retain context and improve across sessions. It combines Markdown-native memory, hybrid retrieval, and self-evolving skills so agent workflows can store knowledge and reuse successful task patterns. The tool is positioned for AI productivity and AI research use cases, with options for managed EverOS Cloud or open-source self-hosted deployment.
Key Features
- Markdown-native long-term memory layer for storing agent and user memory
- Hybrid retrieval that combines structured memory, keyword search, and vector search
- Self-evolving skills that promote successful task trajectories into reusable capabilities
- Deployment flexibility through managed EverOS Cloud or open-source self-hosting
- Designed to help AI agents retain context across sessions instead of starting from scratch
