Why "tested" matters
Anyone can generate a thousand prompts. Almost no one keeps them working.
Run against real models
Every prompt is tested on the current ChatGPT and Claude before it ships — with the output shown, not just described.
Updated when models change
New model release? Packs get re-checked and revised. The date you see is the date it last earned its place.
Specific beats generic
Built for one job each — a cold email, an SEO brief, a client proposal — so they outperform a giant bundle of vague one-liners.
The Tuesday Prompt
One tested prompt in your inbox every Tuesday.
A single prompt you can paste and use that day, plus a one-line note on why it works. No drip funnels, no fluff.
