If you have assembled the classic macOS productivity stack, it probably looks like this: a screenshot tool, a clipboard manager, and a selection-actions utility. Three excellent apps, three licences, three menu bar icons, three sets of shortcuts to remember.
I built @@ because I wanted those three tools to be one system, and because I wanted all three of them to feed the AI agents I already run. This is an honest tour of what that covers and what it does not. The three apps in the title are good software; the argument here is about shape, not quality.
The screenshot tool
⌘⇧3, ⌘⇧4, and ⌘⇧5 — the shortcuts your fingers already know, all rebindable:
- Area capture with live selection, pixel-precise resize, and window snapping, aware of multiple displays and mixed DPI
- One All-In-One bar on
⌘⇧5: draw a single rectangle, then choose area, window, fullscreen, scrolling capture, screen recording, or OCR on that same selection. You never select twice. - After capture, a Quick Access card you can copy, save, annotate, pin, or drag straight into Slack, Notes, or Finder
- A full annotation editor for images, and a video editor that trims, zooms, and exports as video or GIF
No cloud upload and no account. Captures stay on your Mac until you decide where they go. The whole story is on Screen Capture.
The clipboard manager
⌘⇧V opens a searchable shelf of everything you have copied — text, rich text, images, files, links — filterable by type and by the app you copied from.
Two details matter more than they sound:
- Lossless paste-back. Each entry keeps the complete pasteboard representation, so pasting restores rich text as rich text and images as images, not a plain-text shadow of what you copied.
- Concealed entries are skipped. Anything a password manager or the system marks as confidential never enters the history at all.
History keeps the most recent 200 items up to 1 GiB, stays entirely on your Mac, and merges duplicates instead of stacking them. Clipboard History has the rest.
The selection bar
Select text in any app and a compact action bar appears next to it: Ask @@, Copy, Search, Open Link, plus one-click prompts and any action you write yourself — a prompt template with {selection} in it, a URL template, or an AppleScript that hands the text to another app.
If you have used PopClip you know exactly what this is, and the interaction grammar is deliberately the same. Where it differs: Summarize, Explain, and Research run on your CLI agent, and a result can replace the selection in place — always behind an explicit preview and confirmation, never silently. See Selection Actions, or the manual for the short version.
The part three separate apps cannot do
Every surface above feeds one pipeline. Type @@ in any text field and a screenshot, a selection, a clipboard entry, or a Finder file becomes context for Claude Code, Codex, Grok, Cursor, or whichever CLI agent you already run — and the answer comes back where you were typing, inserted with a single Tab. That is the actual reason @@ exists; the three tools grew around it because collecting context and having a good screenshot, clipboard, and selection experience turn out to be the same problem.
Worth being clear about what that means: @@ is a bridge to the agent you installed, not a chat app or a GUI wrapper around one. It ships no model, no account, and no tokens to sell you. For work too big for a preview card, ⌘Return hands the whole thing to a real session in your own terminal and then gets out of the way — see Handoff.
And if you have no agent installed at all, everything in the first three sections still works standalone.
What @@ does not replace
You will still want a dedicated tool if you need cloud upload links for screenshots, team libraries, pinned paste stacks, or PopClip's large catalogue of third-party extensions. @@ trades that breadth for one coherent, local, agent-connected system. That is the deal, stated plainly.
Get it
One licence covers all three tools and the bridge between them. There is a 7-day free trial with no account and no card, every purchase can be refunded in full within 30 days, and it is a native Mac app at 13 MB with no Electron: download it for macOS.
If you want the longer argument for why the three tools belong in one app, it is in Introducing @@ — and if you came here from the agent side, using Claude Code outside the terminal covers the same system from that direction.
