Build the thing a celebrity coach charges $8,250 a year to text you about — in about an hour, with three prompts.
You text it like a human ("I ate tandoori chicken", "short leg day"). It logs every meal, workout, and supplement into a database you own, texts you back your macros, and every night a coach reads your week and sends you one gap and one fix.
The stack: Telegram (free) + Postgres (free) + Claude (or any AI agent that can touch your database) + n8n (runs the workflows). No code gets typed by you at any point.
