The Easiest Custom AI Agent Build Guide Out There: Build Custom Agents in 10 Minutes with Notion

In six months, AI agents have gone from speculative tech to must-haves.

And Notion AI just gave everyone the key to managing their own team of custom agents for $20 a month.

And honestly, you can spin up the prompts to run this team in just a few minutes. Notion isn’t really admitting this, but the key to the magic is their ability to combine smart AI agents with lots of tools to operate against your data.

Work is evolving so fast it sometimes makes me breathless. I just got done writing about how we’re evolving work into AI artifacts a few weeks ago—artifacts are interactive tools that you can create using a prompt in Claude or ChatGPT.

Well, now you can create ENTIRE WORKFLOWS and run them using AI agents in Notion AI. It’s not just one artifact. It’s a whole assembly line. That’s how fast things are moving.

These aren’t simple automations. I’m talking about million dollar pieces of value. Agents that understand context, make decisions, check their own work, and operate across your entire knowledge base for up to 10-20 minutes at a time. They can turn meeting notes into PRDs, act as an interview coach and score your interview responses against custom scoring rubrics, evaluate prompt variants and track them for you, generate task backlogs—whatever repetitive knowledge work is eating your time.

These prompts might seem complex, but I’m gonna show you how easy they are to create. You can use ChatGPT-5 to build prompts to do this with natural language. No code. No API wrangling. Just clear, structured instructions about what you want done. These agents need precision, but ChatGPT-5 is well-equipped to provide that precision and I’m here to give you all the principles and prompt examples along the way.

After hammering on this since launch, I’ve figured out the patterns that work.

• 8 principles that turn wishful instructions into production systems

• I built 3 complete agent templates you can steal

  • You’ll get links to the Notion pages themselves

  • Plus a video breakdown

  • Plus the prompts I used to create the pages

  • These are valuable workflows—they cost millions to run at most companies

• I also built you a master prompt template you can use for other workflows

• And I laid out where Notion does and doesn’t work well (it’s not perfect!)

The future of work isn’t about AI replacing us. It’s about every knowledge worker commanding their own team of specialized agents. That future isn’t in five years. It’s available right now, for about one Netflix per month.

Let me show you exactly how to build your first AI work engine, and why the people who figure this out today will have massive leverage over everyone still copying and pasting from ChatGPT tomorrow.

Every knowledge worker is about to become an AI systems architect. They just don’t know it yet. The good news is it’s really easy with a little bit of LLM help.

The gap between “AI user” and “AI builder” just collapsed to zero. For twenty dollars.

Documents are dead, but AI workflows are exploding to life. Hop aboard—it’s tons of fun!
