KnoKit
Sound familiar?
The good links pile up. The reading doesn’t happen.
A LinkedIn post shares the perfect guide to Kubernetes networking. You save it. Then another, and another. A month later you have forty saved posts and haven’t opened one.
KnoKit makes it one small thing at a time: one page, with its read time shown up front, and a quiz that tells you whether it stuck.
How a lesson works
Pick, read, answer.
Every lesson is the same three steps, so starting one never takes any thought.
Pick a lesson
Every lesson shows its read time and difficulty before you start. A five-minute lesson stays five minutes.
Read the best page
Each lesson opens one page from a source you’d trust, like Docker’s own docs, chosen so you don’t have to search.
Answer the quiz
Every answer comes with an explanation from that page. The lesson only counts as done when every answer is right.
Try one
Three real questions from the app.
Each one comes from a lesson, and its answer is on that lesson’s page.
Sources
Built on pages you’d trust.
Official documentation, well-known books and long-standing guides. Every course reads from one site, so the style and depth stay the same from lesson to lesson.
