Nexus

Nexus is a workout, meal, and body-weight log that lives inside the chat. Say 'bench 4x8 at 80kg' or 'two eggs and toast' and it's logged — Claude estimates the calories and macros, Nexus keeps the record. Ask what you ate yesterday, how your bench is progressing, or whether you hit protein this week, and the answer comes from your actual history. Every day gets one card: calories against your goal, macros, and workouts with PRs flagged. Correct anything by saying so ('that was 90kg, not 80'). Set daily calorie and protein targets once and every day is measured against them. There's also a small social layer: add friends with a code and see each other's daily cards for accountability.
