45d

45d is a web-based learning tool that creates personalized animated courses on any topic you choose. Instead of throwing generic content at you, it first asks what you already know, then builds a course that fills in the gaps. The result is a short, animated, interactive video that teaches you exactly what you need — nothing more, nothing less.

The experience works like this: type in a subject you are curious about, and 45d assesses your current understanding through quick prompts. Based on your responses, it generates a custom animated course with interactive elements that keep you engaged. The animations are built around your knowledge level, so beginners get foundational concepts while advanced learners skip straight to new material. The tool's main selling point is that it adapts on the fly — no two courses are exactly the same.

This is ideal for anyone who wants to learn something quickly without wading through irrelevant material. Students can use it to prep for exams, professionals can brush up on niche topics, and lifelong learners can explore new interests efficiently. The personalized approach saves time and makes learning feel less like a chore and more like a conversation.
