About Alexein
Alexein is a memory layer for AI agents and the people who use them. It keeps what matters from conversations and work, providing every agent with the context needed across sessions and tools. Agents lose context between sessions, so they reread old threads, repeat work and burn tokens; Alexein gives them memory that lasts.
Builders can add memory to their own agents and products using the SDK, API or hosted MCP server. Everyday users get an AI that remembers their work across tasks. Companies can implement one shared memory for every team and agent, with built-in privacy, permissions and control.
