Where is my data stored?

All entries are stored in the browser tab's in-memory state only. Nothing is written to localStorage, a database, or any server. When you close or refresh the tab all entries are permanently deleted. This makes the tool safe for sensitive text that you do not want persisted.

How do I pin an entry?

Click the pin icon on any entry card. Pinned entries are sorted to the top of the list and are excluded from the 'Clear all unpinned' action, so they stay until you explicitly delete or unpin them.

Is there a limit to how many entries I can save?

There is no hard limit in the tool itself. Because entries are stored in memory the practical limit is your browser's available RAM, which is far more than you would ever need for text snippets.

Can I copy rich text or HTML?

The tool stores and copies plain text only. If you paste formatted text from a word processor the plain-text content is captured but formatting such as bold, colour, or bullet points is stripped.

Clipboard Manager

关于此工具

The Clipboard Manager is a lightweight, session-local snippet store that lives entirely in your browser tab. Paste or type any text into the entry field and click Save — it appears instantly in your snippet list. Click any snippet to copy it back to your clipboard with one click. Pin important entries to keep them at the top of the list so they are never buried by newer additions. Use the search box to filter entries by keyword in real time. Delete individual entries you no longer need, or clear all unpinned entries at once. All data is stored in the current browser tab's session only — nothing is sent to a server and everything disappears when you close the tab, keeping your snippets private.

使用方法

1 Type or paste text into the entry field at the top.
2 Click Save (or press Ctrl+Enter) to add it to your list.
3 Click any entry to copy its text back to your clipboard.
4 Click the pin icon to keep an important entry at the top.
5 Use the search box to filter entries by keyword.
6 Click the bin icon to delete an entry, or use Clear Unpinned to bulk-remove.

What a session-local clipboard manager actually does

Your operating system gives you exactly one clipboard slot: copy something new and whatever was there before is gone. That single-slot design is fine until you are juggling several pieces of text at once — a name, an address, a tracking number, a snippet of code — and find yourself flipping back and forth between windows, re-copying the same things over and over. A clipboard manager solves that by giving you a list. Each item you save stays put and is one click away from being copied back, so you can line up everything you need before you start pasting.

This particular manager is deliberately minimal and session-local. When you click Save, the text is added to an in-memory list that lives inside this one browser tab. It is not written to localStorage, not saved to a database, and never sent to a server. The moment you close or refresh the tab, the entire list is gone. That is a feature, not a limitation: it means you can paste sensitive text — a one-time code, a draft message, a password you are about to change — knowing nothing is persisted anywhere after you walk away.

Pinning, searching, and the sort order

New entries are added to the top of the list, so your most recent snippet is always in view. Each entry shows a short preview, the time you saved it, and its character count. Three actions sit on every card:

Copy writes that entry's text back to your system clipboard in one click, ready to paste anywhere.
Pin marks an entry as important. Pinned entries are sorted ahead of unpinned ones and — crucially — are skipped by the "Clear Unpinned" button, so the snippets you reuse all day survive a bulk cleanup.
Delete removes a single entry you no longer need.

The search box filters the list in real time by matching the text inside each entry, so a list of fifty snippets collapses to the one you want as soon as you type a distinctive word from it. Pinned items still float to the top within the filtered results.

A worked example

Imagine you are filling out a shipping form across two browser tabs. You paste your full name, save it, then paste your address and save that too — both now sit in the list. You pin the address because you will need it again on the billing step. Later you save a coupon code and an order number. When the billing page asks for the address again, you do not retype it: you click that pinned entry, it copies, and you paste. When you are done you hit "Clear Unpinned" to wipe the coupon and order number, and the pinned address stays for the next order. Close the tab and even the address is gone, because nothing here outlives the session.

Good uses for it

Form-filling marathons. Stage your name, email, address, and phone number once, then copy each as the form asks for it.
Repetitive replies. Keep a few canned responses or boilerplate sentences pinned while you work through a queue of messages.
Research and writing. Collect quotes, URLs, or stats as you read across tabs, then paste them into your draft in order.
Temporary, sensitive text. Hold a verification code or a freshly generated password just long enough to use it, with no trace left behind.

Common mistakes and limits to know

Treating it like permanent storage. It is not. A refresh or tab close erases everything, pinned or not. For anything you need tomorrow, save it in a notes app or a password manager instead.
Expecting formatting to survive. The manager stores and copies plain text only. Paste a bold, bulleted block from a word processor and the words are kept but the styling is stripped — useful when you actually want to clean formatting out, surprising if you expected it back.
Forgetting the keyboard shortcut. You do not have to reach for the Save button. With the cursor in the entry field, press Ctrl+Enter (or Cmd+Enter on a Mac) to save and clear the box in one motion.
Worrying about a size cap. There is no fixed entry limit; the only ceiling is your browser's available memory, which is far more than any realistic pile of text snippets will use.

Why "nothing persists" is the privacy guarantee

Many web clipboard tools quietly save your history to browser storage or sync it to an account, which is convenient until you remember what you once pasted there. This tool takes the opposite stance: the list exists only as JavaScript state in the current tab. You can verify it by saving a few entries and then refreshing — they vanish completely. Nothing was uploaded, logged, or written to disk, so there is no history to leak and nothing to delete later.
