Osaurus.

Osaurus

Osaurus is a free, open-source AI platform that runs entirely on your Apple Silicon Mac, giving you complete ownership of your data and AI workflows. Unlike cloud-dependent tools, it keeps your conversations, files, and code private while offering the flexibility to tap into powerful cloud models like ChatGPT, Claude, or Gemini only when you choose to.

Product Highlights

• 100% Local Operation: All AI inference happens on your Mac using Apple Silicon — no data ever leaves your device unless you explicitly allow it
• Hybrid Model Support: Seamlessly switch between offline local models (Ollama, MLX, LM Studio) and cloud providers (OpenAI, Anthropic, Google Gemini, Grok) with shared memory across all
• Autonomous Agent Builder: Create AI agents that run independently with voice control, folder monitoring, browser plugins, and parallel task execution
• Zero-Cost Forever: MIT licensed with no subscriptions, usage caps, or hidden fees — yours to use, modify, and distribute
• Native Mac Experience: Built in Swift specifically for macOS 15.5+, delivering millisecond response times with no server round trips

Use Cases

• Private Document Analysis: Process sensitive files, codebases, and confidential data without risking exposure to third-party servers or training datasets
• Offline Development Workflow: Continue coding, researching, and building with AI assistance even without internet connectivity — ideal for travel, secure facilities, or unreliable connections
• Autonomous Task Automation: Deploy agents that monitor folders, execute scripts, and complete multi-step workflows overnight while you focus on higher-value work
• Hybrid AI Strategy: Stay private by default for routine tasks, then selectively invoke premium cloud models only when complex reasoning or specialized capabilities are truly needed

Target Audience

Osaurus is designed for privacy-conscious developers, security-minded professionals, and AI enthusiasts who refuse to trade data ownership for convenience. It particularly appeals to Mac users who want the power of modern AI without surrendering control to centralized cloud services.
