What is Osaurus?

Osaurus is an open-source desktop app for running AI agents on your own computer. You can use local models offline or connect cloud models through your own API keys or prepaid credits. Agents work from folders of documents and references, retain conversation memory locally, and support tools, skills, and scheduled tasks.

File changes require approval, stay within the folder you selected, and can be undone. An Insights view records agent activity, including information sent outside your computer. An experimental Privacy Filter replaces names, emails, and account numbers with placeholders before sending messages to cloud models, then restores them in replies. Cloud requests can still include conversation history, memory, document excerpts, and tool results.

The individual app and local usage are free without an account. The Mac version requires Apple Silicon and macOS 15.5 or later; Windows is available in public beta. Paid Workspaces let teams share agents running on their own computers and use a shared cloud-credit pool.

What can Osaurus do?

  • Offline local agents

    Run Raptor and other local models without an internet connection or local usage charges.

  • Folder-based context and memory

    Give agents your documents and references, with conversation memory stored on your computer.

  • Approval-based file editing

    Review changes before agents edit files, restrict edits to a chosen folder, and undo changes.

  • Privacy controls and activity logs

    Inspect outgoing data in Insights and optionally mask personal details with an experimental Privacy Filter.

  • Tools and scheduled tasks

    Extend agents with MCP tools and skills, and schedule recurring work.

  • Shared team agents

    Workspaces share agents across team computers over a self-hosted encrypted network, with pooled cloud credits.

Privacy-conscious individuals
Work with personal files and AI agents locally without sending requests to a cloud model.
