FAQ
Are the T-Minus AI guides really free?
Yes. No email wall, no credit card, no "free trial" language. Download them, copy them, share them with your team. We fund the site through paid Power Guides and sponsorships disclosed on specific pages.
Which guide should I start with?
If you're trying to fix bad prompts, start with the Prompt Scorecard. If you're juggling multiple AI tools and want a decision framework, start with the Open Claw Field Manual. If you're working across text, images, and documents, start with the Multimodal Context Pyramid.
How often do you update the guides?
Each guide is revised when the underlying frameworks, model capabilities, or pricing changes materially. Dates are published on every guide page. We don't chase every model release — we update when the current guidance would lead a reader wrong.
Can I use these guides in my team training?
Yes — you can share them internally, quote them in training decks, or reference them in onboarding docs. Attribution is appreciated but not required. For commercial redistribution or repackaging, reach out via the contact links on the About page.
