A week ago, we launched the Product Design plugin for Codex. It’s been really cool to see people pick it up and immediately understand what we were going for.
We tried a bunch of ideas with our in-house designers, but kept coming back to two things: ideation and prototyping.
Jumping straight into implementation is expensive when you don’t know what you want yet. Image gen is really good at exploring a few different directions before you spend a ton of tokens on a big build.
It gets much better when you give it references. Run the plugin’s setup flow and throw in your design docs, screenshots, and anything else that helps Codex understand how your product should look and feel.
Once you’ve built the prototype, the in-app Browser and Annotations tools make it easy to keep refining. Reminder that the Annotations tool also allows you to tweak CSS!
Here's five cool examples from our amazing users:
- Exploring and refining three directions before building:

- Cleaning up standard Codex output with Product Design:

- Going from a project brief to design directions, implementation, and detailed refinement:
x.com/libukai/status/2063557…
- Using it across the whole PM workflow, from ideation to sharing a prototype:
x.com/masa_okamura108/status…
- Locking in the style before implementation to avoid a bunch of rework:
x.com/OssanMarmot/status/206…
Some pro tips:
- Use /goal and high reasoning for more ambitious builds. Medium should suffice for lower fidelity builds. We're working on better performance at lower reasoning levels.
- Use Annotations to make target edits.
- Attach Figmas and screenshots to your prompts.
- Run "
@Product Design setup" to create durable design rules for your prototypes.
Special shoutout to Japan for being so pumped about the plugin.
We’re reading all the feedback, learning quickly, and have plenty more to improve.
Keep sharing what you're building and what you'd like to see in the future.
Codexの新Product Designプラグイン、肝はいきなり実装に行かず先に3案出してスタイルを固定する点。手戻りの大半は「作り始めてから方針が揺れる」ここで起きるので、確定フェーズを前段に挟む発想は実務で効く。
