Rool

A private, EU-hosted AI machine with files, software and persistent memory

Private EU-hosted machines

Every workspace runs on servers the company operates inside the European Union, with AI models self-hosted on the same infrastructure rather than forwarded to external providers.

Persistent memory across tasks

The machine remembers prior work and conversation context, so follow-up tasks pick up where the last one ended instead of starting from a blank chat.

Files and software in one workspace

Store and work on documents, and run software inside the same machine, keeping results and context together rather than scattered across multiple apps.

Connectors and custom MCP servers

Attach external tools and services to your machine via built-in connectors or self-configured MCP servers, so the stack you already use is reachable from inside Rool.

+EU data residency with self-hosted models on company-operated infrastructure
+Persistent memory and file context instead of disposable chat sessions
