Create 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!

Teaching since 2020

One creator, one product family.

Hey, I'm Jan. I built SyntaxPath so tutorials, production-ready code, and the upcoming course all feel like one continuous path. Start free on YouTube, go deeper with the kit, and join the course when you want the full roadmap.

Everything here is built by one creator on one stack philosophy. The architecture I teach in public is the same architecture that ships in SyntaxKit, so the voice, code, and workflows stay aligned instead of drifting apart.

The promise is simple: the free layer stays free. Paid products fund the time it takes to keep this whole thing real, current, and worth trusting for the long term.
