Here’s how it’s done. Learning how to build an agentic OS is simpler than it sounds — you put all your AI agents and custom workflows into one dashboard, then automate anything one click at a time. You don’t need to be a coder.
Here’s the full process I use, based on the free one-hour course above.

Key takeaways
- Two paths: build from scratch in ChatGPT Codex (GPT 5.6), or install a ready template zip — the template is much faster.
- Always run it locally for security, and avoid port conflicts.
- Add a memory system (Obsidian) so all your agents share context.
- The ready-made Agent OS zip is in the AI Profit Boardroom.
What You’re Actually Building
An agentic operating system is a dashboard that holds all your agents plus the custom workflows you build — a video agent, an SEO content pipeline, a lead-gen and outreach tool, a trending-news workflow — each one a click away. The whole point is to automate the repeatable work you do every day.
The mindset that makes it work: focus on the system, not the model. Models come and go (Fable 5 got taken down; GPT 5.6 dropped) — but if you build a solid system, you just swap models in and out without rebuilding anything.
How to Build an Agentic OS (Step by Step)
- Pick your builder — ChatGPT Codex (GPT 5.6) is great; Claude works too. It’s the most visual way to build.
- Build the dashboard — ask it for a clean mission-control dashboard to operate Claude, Codex and Hermes together.
- Run it locally — on a fixed local port, fully operational (able to edit files), not a chat. Local = secure.
- Add a memory system — wire in Obsidian so every agent shares the same context (the ‘memory galaxy’).
- Add custom workflows — build a video agent, SEO pipeline or lead-gen tool, one per job you want automated.
- Test and fix — actually run each feature, screenshot bugs, and ask it to fix them.
- Build in parallel — fork the chat so several workflows get built side by side.
It really can take a couple of hours of testing and fixing — which is exactly why a template saves so much time.
From Scratch vs Template
| From scratch | Ready template | |
|---|---|---|
| Time | A few hours (and future fixes) | 10–20 minutes |
| Reliability | May break; needs testing | Installs and works |
| Control | Total, but slower | Full — you still customise it |
| Best for | Learning the guts | Getting results fast |
If you want to save time, start from the template inside the AI Profit Boardroom and customise from there. If you want to learn every part, build from scratch. See also my agentic OS download guide.
Keep It Free (and Modular)
You can build all of this for free using subscriptions you already pay for — plug your Claude or ChatGPT plan into the CLI so you don’t burn API tokens. Add free tools too: OmniRoute for free coding, HY3, and local models via Ollama for the tasks that don’t need frontier power.
Keep it modular — give yourself the option to hide tools you’re not using. You won’t use every feature, and the simpler you keep it, the better.
Add Auto-Notes With Omi
A tip that makes the memory system far better: use Omi, a free open-source tool, to auto-capture what you’re working on. It listens, takes notes with more detail than you’d write yourself, and exports straight to Obsidian — so your memory galaxy fills itself in without you lifting a finger.
Mistakes to Avoid
- Don’t run two agents on the same task. Claude and Codex working the same files can overwrite or delete each other’s work — use one agent to build the OS.
- Watch your tokens. Building lots of workflows in parallel burns tokens fast; dial down effort, speed and model for simple jobs, or use a token-minimiser.
- Don’t over-build. You won’t use every feature — the simpler you keep it, the better.
- Test everything. A fresh build often creates a nice UI but forgets to make it actually work — run it and fix what breaks.

FAQ
How do I build an agentic OS?
Ask ChatGPT Codex (or Claude) to build a local mission-control dashboard for your agents, run it locally, add an Obsidian memory system, then add custom workflows one at a time — testing each as you go.
Do I need to code to build an agentic OS?
No. You describe what you want in plain English and the AI builds it. You just test, fix and customise.
Should I build from scratch or use a template?
A template installs in 10–20 minutes and works; from scratch takes hours but teaches you the guts. Most people are better off starting from a template and customising it.
Can I build an agentic OS for free?
Yes — use subscriptions you already have via the CLI (no extra API cost), plus free tools like OmniRoute and local Ollama models.
Why run the agentic OS locally?
Security. If you expose it to multiple devices and it can edit files, that’s risky. Running locally keeps control on your machine.
