CmdZero
Efficient in-context AI editing
AI is great at building the first 90% of an app. CmdZero is my answer for the last 10% - the small tweaks and finishing touches that make a project feel like yours.
Small edits shouldn't cost big tokens.
When I build with AI, the big stuff comes together fast. Then most of my time goes into small changes: nudge the spacing, reword a label, tweak a color. Sending those to a frontier model felt wrong every time. It's slow, it burns tokens, and it often edits the wrong thing.
I wanted those edits to be instant, so I built CmdZero.
Click the thing. Say the change.
CmdZero runs inside your app while you're developing. You click the element you want to change and describe the change in plain words. Because it knows exactly what you clicked, it never has to search the codebase to find it.
Then it routes by size. Style-only tweaks skip the model and run as a direct code transform. Small edits go to a small, fast model. Only the genuinely tricky changes hit the big one. Either way it edits your real files, so all you get back is a clean diff to review.
It knows what you clicked
No searching, no guessing which file to touch. The change starts exactly where you pointed.
It edits your real code
Changes land in your actual files as clean, reviewable diffs, not regenerated components.
Right-sized AI
Easy edits stay cheap and instant. The big model only shows up when the change actually needs it.

This portfolio runs CmdZero. Most of the polish you're looking at was made with it.
Open source, and running on this site.
CmdZero is live and free to use. I think this is roughly how the finishing work on AI-built software gets done, and building it in the open on my own projects is the fastest way to find out if I'm right.
