Overview
BaseRT and Dayflow are two distinct open-source macOS tools that leverage AI but serve very different purposes. BaseRT is a high-performance LLM runtime optimized for Apple Silicon, delivering the fastest inference speeds for local models. Dayflow is an automatic work journal that uses screen recording and AI to log your daily activities without manual input. This comparison explores their features, pricing, and ideal use cases.
Feature Comparison
