The Problem With Your Operating System’s Clipboard

Copy one thing, and whatever you had copied before is gone. That’s fine until you’re pulling three different snippets from three different tabs into one document, bouncing back and forth re-copying things you already had a minute ago. That’s the entire reason this tool exists: four slots instead of one, so you can hold onto more than a single thought at a time.

A Quick Example of How People Actually Use It

Drafting an email that references a phone number, an address, and a reference code pulled from three different places? Copy each one into its own slot as you find it, then paste them into the email in whatever order you actually need them — instead of copying, alt-tabbing, pasting, and going back to copy the next thing.

What It Does, Plainly

  • Four independent slots that don’t overwrite each other.
  • One-click case conversion (UPPERCASE, lowercase, Title Case) for when you’re pasting into a form that has its own strict formatting rules.
  • Whitespace cleanup for text copied out of a PDF, which almost always comes in with broken line breaks and awkward hyphens.
  • Markdown stripping, for when you’re copying from a chat app, Notion, or Slack into somewhere that renders **asterisks** literally instead of bold.

What It Deliberately Doesn’t Do

It doesn’t sync across devices — it’s tied to the browser you’re using, saved strictly in that browser’s local storage. If you need the same clipboard on your phone and laptop, that’s a different tool entirely (a full cross-device sync tool that still doesn’t touch a server is a bigger build than a scratchpad, and it’s on our roadmap — for now, this one is a single-device tool, on purpose).

Frequently Asked Questions

Will I lose my slots if I close the tab?

No — they’re saved to your browser’s localStorage, not just held in temporary memory, so they survive a tab close or even a full restart of your browser. They won’t survive clearing your browser data, since that’s what local storage clearing intentionally does.

Can someone else using my computer see what’s in my slots?

If they have access to your unlocked computer user account or browser profile, yes — browser local storage isn’t encrypted by default. If you’re pasting something sensitive like API keys or master credentials, use our Vault tool instead, which encrypts what you store with AES-256-GCM.

Why only four slots and not unlimited?

Past four, most people stop being able to remember what’s in which slot without labeling them, at which point you actually want a full notes app, not a fast clipboard scratchpad. Four slots provides the optimal cognitive balance between multi-item buffering and zero mental overhead.
