What is Sage?
Sage offers a streamlined, native macOS and iOS experience for interacting with Anthropic's Claude AI models. Instead of relying on web interfaces, Sage provides a dedicated application environment, maximizing performance and integrating seamlessly with your Apple ecosystem. If you frequently utilize Claude for development, research, or other technical tasks, Sage enhances your workflow with powerful features designed for efficiency and control.
Key Features:
🧠 Access Multiple Claude Models: Directly switch between various Claude models, including Claude 3.7 Sonnet, Claude 3.5 Sonnet, Claude 3 Opus, Claude 3 Sonnet, and Haiku. Select the model that best suits the complexity and speed requirements of your current task.
🔍 Activate Extended Thinking Mode: Gain deep insights into Claude's reasoning. Toggle Extended Thinking Mode (Command+Shift+T or via the toolbar) to observe Claude's thought process in real-time, displaying detailed reasoning blocks. This is invaluable for debugging prompts or understanding the nuances of Claude's responses.
🛠️ Manage Conversations with Precision: Maintain a clean and organized workspace. Sage automatically generates titles for your conversations, allows you to edit messages and attachments after sending, and enables you to fork conversations to explore different branches of inquiry without losing context. Prompts are automatically cleared to keep things tidy.
⚙️ Customize System Instructions: Tailor Claude's behavior to your specific needs. Configure persistent custom system instructions within Sage's settings (Settings → AI → Custom Instructions) to influence the default response style (concise, verbose, or default) across all conversations.
🔌 Integrate with Powerful Tools: Extend Sage's capabilities through seamless integrations. Connect to your mcp.run accounts (Settings → Tools → mcp.run) and gain access to a vast library of tools via Smithery. Built-in calculators and map tools are also available directly within the conversation interface.
Use Cases:
Prompt Engineering and Debugging: A developer is refining a complex prompt to generate specific code output. They use Extended Thinking Mode to analyze Claude's reasoning, identify areas where the prompt is ambiguous, and iteratively improve it to achieve the desired results.
Technical Research and Analysis: A researcher is exploring a new scientific concept. They utilize Sage to quickly switch between Claude models, comparing the outputs of Claude 3 Opus and Claude 3 Sonnet to assess which model provides the most accurate and comprehensive information.
Development Workflow Integration: A software engineer integrates Sage into their daily workflow. They use custom system instructions to ensure Claude consistently formats responses in a way that's compatible with their codebase, saving time and reducing manual formatting.
Conclusion:
Sage provides a superior, native environment for power users of Claude AI on macOS and iOS. By offering fine-grained control, insightful debugging tools, and seamless integrations, Sage empowers you to maximize the potential of Anthropic's models and streamline your technical workflows. Bring your own Anthropic API key and experience the difference.
