Why now

Riley predicts that Codex will be the 'everything app' and companies building specialized interfaces inside it will 'make a killing'.

Market gap

Most AI tools are currently standalone 'destination' sites; the gap is in tools that live inside the user's primary AI 'flow' state.

Business fit

Type: SaaS / Plugin
Target: Knowledge workers who use Codex as their primary desktop OS for AI.
Revenue: $50 - $200 per user/month (SaaS subscription).
Founder: Software engineers who can navigate the OpenAI/Codex plugin approval process.

Proof signals

OpenAI is pushing all efforts into Codex as a single 'Red Alert' priority.
The shift from terminal (Claude Code) to GUI (Codex) indicates a platform shift.
Riley mentions companies already building specialized plugins like Canva and Remotion.
