What you'll learn

What changed for ChatGPT plugins after OpenAI's DevDay 2026

See where your product fits among plugins, the directory and OpenAI's new dots agents.

How ChatGPT decides which plugins to recommend

Learn what OpenAI says it rewards, and the part of your plugin most teams overlook.

Which plugin features work only in ChatGPT

Compare OpenAI's new extensions with standard MCP Apps, so your plugin can also run in Claude.

How to build a plugin with my prompts & which tools to use

Get my prompts and a GitHub repo so you can build your own plugin, start to finish. And get a list of tools that work.

What to watch out for when you submit to OpenAI

Avoid the gotchas I hit getting my plugin approved, so your first submission doesn't get rejected (and what to fix).

Why this topic matters

Big news: Sam Altman is doubling down on plugins. There are only 5,066 so far and your product could be next. ChatGPT now recommends them mid-conversation. They also work in dots, the new agents everyone will be trying. I've been building plugins since January, 2026 and already have one approved in the directory. I'll show you how to build it right, how to design it and what to watch out for when you submit. You get my prompts and a GitHub repo.
