Lucy AI

Lucy Direct download link Lucy, originally by u/Neurogram, is a Siri Shortcut for iOS, iPadOS, and macOS that integrates with any OpenAI API-compatible Large Language Model (LLM) endpoint. It operates by utilizing other shortcuts as tools to accomplish tasks. Lucy works with full control over planning and execution, calling tools sequentially without requiring user input or oversight. This is similar to the model context protocol (MCP) that's gaining popularity in the AI community, where a model can call other models or tools to complete tasks. You can run the Lucy shortcut directly, or share text/image to Lucy to use it as context. Try running Lucy and ask what it can do! This shortcut was initially introduced by u/Neurogram. I expanded Lucy's capabilities and toolset, and enhanced its existing tools. Other improvements include: Image input support Improved user communication (including presenting lists of choices where appropriate) Menu system to guide configuration of LLM and tools Automatic downloading of missing or updated tools Multiple tool calls in a single LLM response JSON validation of LLM responses to prevent errors or crashes Optional debug logging (requires the free "Logger for Shortcuts" app) Configurability: Lucy is configurable to meet user preferences: Tool Access: Users can select which tools Lucy has access to, either for a single run or on a persistent basis in the settings. Permissions: Each tool can be configured to require user permission before use. If enabled, approval can be granted for each individual usage or once per tool per Lucy run. Notifications: Notifications can be configured to show when each tool is used. Tool Management Lucy's tools are separate Siri Shortcuts. You get to decide which tools will be loaded. Enabled tools download automatically when you run Lucy if they've been updated or are not yet installed. When you first run Lucy, you'll have to install Lucy's many tools. It will attempt to do this in a streamlined fashion without needing to rerun Lucy too many times. Sorry in advanced for any excessive tapping!
