Rackey

Rackey is a productivity tool that connects your email, calendar, notes, and daily briefing in one place. It is built around separate agents, where each agent handles one specific task.

The email agent reads your Gmail messages and helps identify which emails need attention. An LLM ranks the messages and extracts promises or commitments from them. Before anything is shown to the user, the system checks that every quote actually exists in the original email. If it does not, Gmail’s own snippet is used instead.

The calendar agent reads upcoming events and checks for overlapping times using regular code. The LLM is only used to write the explanation shown to the user.

For follow-ups, the email and calendar agents work at the same time. Rackey then compares promises found in emails with calendar events using a fixed text-matching function. It removes common words and checks whether at least 34% of the useful words overlap. This decision does not involve an LLM.

Users can also save results to Notion or send a daily briefing. Both actions require confirmation. The briefing reuses the email and calendar results already collected instead of running the entire process again.

Rackey is designed so that AI handles language, while important decisions remain controlled by code.
