You can already build with AI, but the hard part is knowing what to build. Instead of asking AI to invent random startup ideas, you build an AI Pain Radar that scans real public complaints, captures the raw evidence, and turns repeated frustration into business ideas backed by the posts that inspired them.
You will build a simple two-table Airtable base and connect it to recurring Codex automations.
The first automation finds public complaint signals and turns them into linked business ideas. The second automation, covered in the Going Further section, takes the top-rated idea from the previous day and creates a simple landing page proof of concept in a local folder.
In this guide, we will show you how to use Codex and Airtable to build an endless business idea generator. It is made for people who already build websites, apps, or automations with AI, but need a better way to find painful problems people might actually pay to solve.
By the end, you will have an Airtable base that stores the evidence behind each idea, and Codex automations that keep researching new complaints, generating business ideas, and turning the best ones into simple tests.
By the end of this tutorial, you'll be able to:
Connect Airtable to your Codex instance
Instruct Codex to create an Airtable schema
Make the base easier to review
Set up the Reddit pain radar automation
Score ideas without losing the evidence
Test the system before you rely on it
Let's get right into it!
