In this post, I'll start from scratch and build up to OpenClaw's architecture step by step, showing how you could have invented it yourself from first principles, using nothing but a messaging API, an LLM, and the desire to make AI actually useful outside the chat window.

End goal: understand how persistent AI assistants work, so you can build your own (or become an OpenClaw power user).

First, let's establish the problem

When you use ChatGPT or Claude in a browser, there are several limitations:

#Loading Tweaks in the Simulator

With the latest updates to the simulator, this turns out to be pretty simple:

You need to be using kirb/theos

In order not to require MobileSubstrate to be loaded and your tweak to be compiled for i386/x86_64, add

In your makefile:
