24h 7mCreate a B2B AI SaaS with Next.js
Ever wanted to build a SaaS, and not just any SaaS, but a B2B SaaS with AI functionality included? Well, I have news for you, because in this video, we are doing exactly that. We are creating a team communication software with organizations, channels, fancy infinite scroll, oh, did I already mention billing? Of course, we will have billing implemented. Not only that, but we have thread support baked in, reactions, and of course, all of this is done in real-time using Cloudflare Durable Objects. But wait, we set out to create a B2B AI SaaS, and therefore, it's infused with AI. Not only can users easily summarize threads, but we also have a full-on AI composer. Need help with your message or just want to fix the grammar? The composer is there to help with one click of a button. This is literally the most in-depth tutorial I have ever created, and I am excited for you to get started on this project!

Everything here started as a YouTube video.
Hey, I'm Jan. For the past few years I've taught modern web development on YouTube to a community of more than 55,000 developers: full-length courses, real projects, no fluff.
The free tutorials are where you watch me build. The starter kit is that same architecture, hardened for production. And the course will tie it all together into one coherent path. Same voice, same standards, everywhere.
