Gemini Flash Logic
Note: This mockup is powered by the Gemini Flash API and is designed to model how a modern generative AI system may extract key entities, structure summaries, and interpret message priority.

Results are indicative rather than definitive. Actual inbox experiences can vary based on recipient behaviour, engagement history, authentication signals, and mailbox provider systems.

GAL Score™ provides a structured, machine-eye perspective on your content — helping you optimise for AI-assisted inbox environments while keeping your message clear for human readers.
