Which Copilot do you have?

Two of the three labels are free, and nothing in the app announces which one you are on. Copilot for Busy People compares them, then gives you one page for your tier: five habits, six lines to paste, and an honest list of what it still gets wrong. Free, and it never asks for an email.

Your first 10 AI implementations, by function

One free two-page card per function: ten builds in the order to build them, each with its mode, difficulty, deploy estimate and impact, and the list of what the first ten leave out on purpose.

Copilot agents
Decision tree

Which Microsoft agent tool do you actually need?

Before you build one: Agent Builder, Copilot Studio, or Microsoft Foundry Agent Service. Four questions, a decision tree you can screenshot into a deck, and what each one puts on IT’s desk, including the tenant-wide agent registry and the two numbers on it worth more than the total.

Some of these agents consume Copilot Credits. For the numbers, see M365 Copilot agent cost and pricing (2026).

Not only Copilot
Mistral Vibe

Make Vibe useful at work

Six one-page guides for Mistral Vibe Work, plus a worked exercise with an answer key written before the model saw anything. Three fictional contract documents, a prompt to paste, and a check on what came back: the dates, the arithmetic, which amendment replaced which term, and the schedule that is referenced but missing. Read them on the page, or take the Word and PDF pack.

Working in the Vibe CLI rather than the browser? Mistral Vibe on one page covers that side, including how skills are discovered and why a correct file can fail silently. Independent and not affiliated with or endorsed by Mistral AI.
