Clipboard History Viewer for Mac: How It Works

macOS gives you exactly one clipboard slot. Copy a phone number, then copy an address two seconds later, and the phone number is gone — there's no built-in viewer to scroll back through what you copied earlier. A clipboard history viewer fixes that by recording each copy so you can pull any of them back.

What a clipboard history viewer actually does

When you press Cmd+C, the system clipboard (the "pasteboard") replaces whatever was there before. A clipboard history viewer sits in the background, notices each change, and stores a timestamped copy of it. Instead of one slot, you get a scrollable list.

With ClipHistory you open that list with Cmd+Shift+V. It shows your recent clips — text, links, rich text, and images — newest first. Pick one, hit Return, and it pastes into whatever app is in front.

What gets captured

• Plain text and formatted (rich) text
• URLs and code snippets
• Images copied from browsers, Preview, or screenshots
• File references you copy in Finder

Everything is stored locally on your Mac. ClipHistory has no cloud sync, no account, and no telemetry server collecting your clips. What you copy stays on the machine you copied it on.

How many clips you can see

ClipHistory keeps your last 150 unpinned clips. When clip 151 arrives, the oldest one rolls off. That's a deliberate, predictable window — not "unlimited" marketing — so the list stays fast and you're not scrolling through last month's noise.

If you have items you never want to lose — a license key, a wiring address, a boilerplate paragraph — you pin them. Pinned clips don't count against the 150 and never roll off. You can pin as many as you want.

Finding a specific clip fast

A viewer is only useful if you can find things in it. ClipHistory gives you:

• Search — start typing and the list filters live by content
• Type filters — show only images, only links, or only text
• Boards — group related clips (a project, a client, a research session) so they're not buried in the timeline

Paste stack for sequential pasting

When you're filling a form or moving several values between apps, the paste stack lets you queue multiple clips and paste them one after another in order — instead of bouncing back to the history list between each paste.

AI transforms on any clip

Because ClipHistory already has the text in hand, it can transform it before you paste. Using your own API key from one of five providers — Anthropic, OpenAI, DeepSeek, Google, or a custom endpoint — you can:

• Summarize a long copied passage
• Rewrite it in a different tone
• Translate it to another language
• Clean messy formatting, line breaks, or tracking junk out of a copied link

The request goes from your Mac to the provider you chose with the key you supplied. ClipHistory doesn't route it through any server of its own.

Is it safe to run something that watches your clipboard?

Reasonable question — the clipboard often holds passwords and tokens. Two things matter:

1. It's local. Nothing leaves your Mac unless you explicitly trigger an AI transform, which goes only to the provider whose key you entered.
2. It's signed and notarized by Apple. That means Apple has scanned the app and verified the developer identity, so Gatekeeper opens it cleanly instead of warning you about an unidentified developer.

ClipHistory is a universal binary, so it runs natively on both Apple Silicon and Intel Macs, and it needs macOS 12 or later.

Getting started

1. Download and open ClipHistory (it opens cleanly thanks to notarization)
2. Grant accessibility permission so it can paste into other apps
3. Copy a few things as you normally would
4. Press Cmd+Shift+V and watch your history appear

From there, pin what you reuse, search what you forget, and let the 150-clip window handle the rest.

How it compares to the built-in clipboard

macOS does include one small window into the clipboard — Finder's Edit → Show Clipboard — but it only ever displays the single most recent copy. There's no search, no list, and no way to recover something you copied earlier. A clipboard history viewer is the difference between "what's on my clipboard right now?" and "let me grab that address I copied twenty minutes ago." Once you've used the second one, going back to a one-slot clipboard feels like working blind.

It's also a one-time $19.99 purchase with a 12-month license — no subscription and no auto-renewal — so the viewer keeps working without a recurring charge.

Stop losing what you copied. ClipHistory keeps your last 150 clips (plus unlimited pinned ones) right under Cmd+Shift+V — local, private, no account. Get ClipHistory for macOS — $19.99 one-time.
