AISDK docs are already really good, so this guide is not trying to replace them. I wrote it because I wanted something I could share with friends and coworkers who already know Next.js, but feel a bit lost when they first see generateText, streamText, tools, and all the different examples. My goal was to make a very visual walkthrough of the core primitives, so that you can open this page next to the official docs, click through the demos, glance at the code, and feel comfortable building with AISDK without spending days getting your hands dirty just to understand the basics.
