SuperPaste uses your active window to write for you. Place your cursor anywhere — email, Slack, a form, code — and the right text shows up instantly.
7-day free trial · $5/month after · macOS 14+
No copy-pasting, no app switching, no explaining context. Just press a key.
Click into any text field — an email reply, a Slack message, a form, a code file. Anywhere you'd normally type.
SuperPaste takes a single screenshot of your active window and sends it to Claude over an encrypted connection. A subtle indicator shows it's working.
The response is pasted directly into your field — no ⌘V required. Done before you've moved your hands. Don't like it? ⌘Z undoes it.
SuperPaste reads what's already on your screen — the question, the thread, the form — and writes the thing you were about to type.
On your screen: a client asking to move tomorrow's call.
"No problem at all — tomorrow is tight, but I could do Thursday at 2pm or Friday morning. Whichever works best for you."
On your screen: a teammate's question in a busy thread.
"Yep — fixed in 2.3.1. It was the CSV encoding issue; exports with special characters work now."
On your screen: a form field with its label visible.
The answer for that field, written right where your cursor is — no retyping your life story into yet another form.
On your screen: a failing test, a stack trace, or a // TODO.
The fix or implementation at your cursor — it can see the error and the surrounding code.
One hotkey. Zero prompting. If you can click into it, SuperPaste can write into it.
SuperPaste captures exactly what you can already see, sends it once, and discards it. That's the whole story.
Don't take our word for it — read the code.
SuperPaste is MIT licensed. Every line that touches your screen is public.
The screenshot capture, the API call, the discard — it's all on GitHub. No hidden telemetry, because there's nowhere to hide it.
Bring your own Anthropic API key and the app costs nothing, forever.
The hosted plan covers Claude usage and works the minute the DMG opens. Same code either way.

Prefer to run it yourself? SuperPaste is open source — compile it with your own Anthropic API key, free forever.
Screen Recording is the macOS permission for capturing the active window — one screenshot, only when you press ⌥V. Accessibility lets SuperPaste register the global hotkey and paste at your cursor. It never records video and never reads your keystrokes.
No. The screenshot is sent over an encrypted connection, used to generate one response, and discarded. No storage, no training, no logs of your content.
Anywhere you can place a cursor and ⌘V works: Mail, Slack, every browser, IDEs, Notes — native and Electron apps alike.
Nothing is sent or submitted — text is just pasted at your cursor. Read it, edit it, or press ⌘Z and it's gone. You're always the last step.
No — it needs Claude to think. Offline, pressing ⌥V simply does nothing; you'll see a quiet error and your screen goes nowhere.
Generation pauses until you subscribe — $5/month, cancel anytime. Nothing is auto-charged; the trial needs no card. Or compile from source with your own API key, free.
Yes — MIT licensed, with the full source at github.com/brainsparker/superpaste, including both the app and the server.
Download SuperPaste, open it, and press Option V. That's it.
