Desktop agent · macOS and Windows
Memento Science
A desktop agent that handles chat, document work, web search, and multi-step task automation in one place. It keeps long-term memory across sessions, so the parts of your workflow it has seen before get faster rather than starting over.
Learns your workflow
Long-term memory and self-optimisation mean it adapts to how you actually work instead of resetting at every session boundary.
Wide tool reach
Integrates external tools and protocols, so complex tasks, file analysis, and web research run through one agent rather than several disconnected ones.
Runs unattended
Workspaces, scheduled tasks, and automatic maintenance keep long jobs running without babysitting.
Getting it
Builds are published for macOS and Windows. The release page detects your platform, offers the matching build, and keeps the full version history with per-release notes.
What it is built on
Memento Science is the productised end of our work on deployment-time learning: keeping the model frozen while the agent accumulates experience in external memory. The papers behind it are Memento 1, Memento 2, and Memento-Skills.
