I've been noting things in a gitignored USER_NOTES file and asking agents not to touch it. LOL
Then I saw shadcn's copper solving exactly this. But I am poor and unemployed, so I didn't want to pay.
So I spent a weekend and vibe-coded JogPad. Not aiming to be an exact clone of copper. I built this to scratch my own itch so whatever I find useful I'll throw in there.
In short, JogPad allows you to take quick notes by doing "shift shift" whenever you want. When the floating UI is in focus, you can do "shift shift" again to hide it. If you have text already highlighted, "shift shift" records that in your pad. Pretty simple app but I have found it pretty cool.
Free, open source, MIT licensed. Notes stay in a local Markdown file. No account, no sync.
Try out the browser demo, it's powered by the same UI code that runs in the native app.
Thought it's worth sharing. Do check it out and let me know what you think!
(Sorry it's macOS only for now. no plans for windows/linux atm...)
