The Copilot kit that tells you what works, what doesn't, and when to close the tab.You probably tried Copilot already. A few good summaries, a few confident but wrong answers, and then the tab went quiet. That is not a you problem. Most Copilot guidance shows the demo and skips the failure modes, so you find the edges the hard way. This kit is the honest version: every app card names the 3 prompts that work, the 3 mistakes that waste your time, and what to skip Copilot for entirely. There is a whole chapter on when not to use it at all. One tier, $39, everything included.Every app card carries a "Skip it for" line. The promise isn't that Copilot is magic. It's that you'll know exactly where it helps, where it doesn't, and how to tell a good answer from a plausible wrong one.I'm an independent practitioner, not a Microsoft employee, partner, or reseller. I deploy Microsoft 365 Copilot inside a 17,000-person engineering enterprise and maintain open libraries of Copilot prompts and agents used by thousands of practitioners. I have no licence to sell you, only what actually works.What's inside 14 reference cards: 5 durable Foundations + 9 app cards (Outlook, Word, Excel, PowerPoint, Copilot Chat, Notebooks, Cowork, Teams, Researcher & Analyst). Each card gives you when to use it / skip it for, the 3 prompts that work, the 3 mistakes to avoid, and a one-line "Remember." So you stop guessing and start with what's already been tested. "Copilot on One Page": a single-page system: THE LOOP (Ground → Draft → Check → Decide), THE PROMPT (Goal · Context · Source · Format), THE RULE ("AI prepares. You decide."), and THE 3 RISKS (Hallucination · Mis-citation · Over-trust). The page you tape to the wall and stop relearning. A 30-minute user guide (~33 pages): Start Here (a 5-minute path), Fast Start (a real win in 10 minutes), a before/after of what changes in your week, the one chapter on how to get a good answer every time (prompt + ground + verify), "When NOT to use Copilot," "Data, trust & the EU boundary," a 2-week practice plan (10 drills, ~10 min/day), and a proficiency self-check. So you go from occasional user to genuinely good, fast. Who it's forAnyone with a Microsoft 365 Copilot licence who wants to be genuinely good at it, fast: PMs, finance, ops, HR, executive assistants, managers, and consultants.Who it's not for IT admins deploying or governing Copilot across a tenant: this is about using it well, not rolling it out. Executives evaluating whether to buy Copilot: this assumes you already have a licence. Running the rollout itself rather than just using the licence? Then this is the smaller tool. The M365 Copilot Deployment Kit ($97) is built for the person deploying Copilot across a tenant; this kit is for the people using it once it lands.PricingOne tier: $39. The guide, all 14 cards, and the one-page system. Buying for a team? Email mathieu@kesslernity.com for a team quote.Licensed, not sold.
