Show HN: Caret – Tab to Complete at Any App on Your Mac

Caret represents the practical endpoint of local LLM deployment: bringing intelligent completion capabilities to every application on a user's machine without requiring cloud connectivity or API calls. By hooking into the Mac's input system and providing tab-triggered completion, this tool demonstrates how smaller, locally-optimized models can deliver real productivity value while maintaining privacy and offline capability.

Building applications like Caret requires solving several technical challenges specific to local inference: model size optimization to run smoothly on consumer hardware, latency reduction for responsive user interaction, and efficient context switching between different applications. The fact that such tools are now appearing in the "Show HN" community suggests the infrastructure for practical local deployment has matured significantly.

For local LLM practitioners, Caret validates an important thesis: there's genuine user demand for on-device inference features, and the performance and compatibility requirements are achievable with current open-source models and optimization techniques. This kind of application-layer innovation drives adoption of local deployment approaches.
