Two taps to keep it. One click to use it.

Claude in one window, Codex in another, three tabs of docs, a terminal. Something worth keeping goes past — a prompt you'll want again, a stack trace, the follow-up you thought of while reading. Saving it means stopping, finding somewhere to put it, and coming back. So you don't. You DM it to yourself, or bookmark it, or leave the tab open forever. It's gone either way.

Plux: double-tap Shift and whatever's selected is saved — you never left the window. Cmd/Ctrl+Shift+I does the same for a region of the screen, so the error you're looking at goes in the same place as the text.

Later, one click puts it into ChatGPT, Claude, Cursor, Codex, Codexia, or your terminal — not copied to your clipboard for you to paste. Actually placed: Plux opens the app, waits until it's really frontmost, focuses the input, and drops the text in. Window focused, text placed, ready to send. It never hits Enter for you, and your previous clipboard comes back afterwards.

See it below — capture, then send. That's the whole loop.

Neither half is new on its own. Together they're the reason you'll actually use it: capture is cheap enough that you do it, and getting it back out is cheap enough that what you captured doesn't rot in a list you never open.

Everything you save lands in one list, not a pile. Sort it into folders per project, pin what matters, tick off what's done, and filter by the app it came from. Done with something? Archive it or send it to trash — it stays out of your way without you second-guessing whether you actually needed it.

Tools in this shape are almost always Mac-only; if you've watched one go past and couldn't buy it, this is the one you can. Windows isn't a port that half-works: the parts that touch the OS — the shortcuts, reading your selection, placing text in the next app — are written separately for each platform.

Everything stays on your machine — a file you own, no account to make.

Every note that shaped this page was captured with Plux.
