He rebuilt a speech pathologist’s 15 year old scoring spreadsheet as a web app in one afternoon
A family member who works as a speech pathologist scored a 70 question assessment in a 15 year old spreadsheet full of macros.

Sync my Oura data - and go easy on me when I slept badly
When every Oura MCP server turned out unmaintained, the AI suggested a simpler design - a SQLite database with a cron sync - and built it.

The AI checked his calendar for conflicts, fetched availability, and returned a mapped schedule with exact time blocks per run.
Merge LoseIt and Garmin into one daily health dashboard with AI
A commenter describes a local desktop app the AI helped him write: a script runs daily to pull his LoseIt nutrition and Garmin workout data into a local database, and an MCP link lets the AI review each day in a small browser UI, give advice, and plan runs or swims toward his goal of losing 40 pounds.

A Meta Connect-stage carousel featuring creator Nina-Marie Daniele (Nina Drama, via someone, 2.5M followers) shows her setting a goal to 'train like a pro fighter' with her AI avatar 'Drama Queen.' A Days 1-7 video diary shows a structured plan (warm-up, interval sprints, tire lifts, assault bike), track intervals with AI breathing coaching, a recommended Tempeh Grain Bowl for 40g protein, sleep-score checks, and gym work (punching bag, battle ropes). Comments were hostile to the 30-day p
