Online Notepad

This free online notepad opens instantly and saves what you write as you type, with no account and no install. Keep several notes side by side, switch on a Markdown preview, run find and replace, write full screen in focus mode, and download any note as text or Markdown whenever you want.

What does this online notepad do?

It opens and you write. No account, no install, no waiting. What you type is saved as you go, straight into your own browser.

  • Autosave on every keystroke, with a "Saved" indicator so you can trust it.
  • Several notes, listed on the left, each titled automatically from its first line.
  • Markdown preview, so a note can be plain text or formatted, your choice.
  • Find and replace with a live match count before you commit.
  • Focus mode, which fills the screen and hides everything else.
  • Copy and download as .txt or .md.

Where your notes are saved, and what that means

Your notes are stored in this browser only. This is the most important thing to understand about the tool, so it is worth being blunt rather than burying it.

There is no cloud. There is no backup. There is no sync. Nothing you write is uploaded, which is exactly why it is instant and private, and also exactly why it has limits.

What happensAre your notes still there?
Close the tab, reopen laterYes
Close the browser, restart the computerYes
Come back tomorrow, same browserYes
Open the page on your phoneNo, notes do not travel
Open it in a different browserNo, storage is per browser
Clear browsing data or site dataNo, they are gone
Use private or incognito modeNo, it is wiped when you close it

So use it the way it is meant to be used: a fast, private scratchpad you can trust for today, with a download button for anything you need to keep. If a note matters, download it.

Who can actually read your notes?

Nobody over the internet. Your text never leaves your device, so there is no copy on a server, nothing tied to your IP address, and nothing another visitor could reach. Browser storage is also locked to this one domain, so no other website can read it either.

There is one real exception, and it is worth stating plainly: anyone using the same browser profile on the same computer can open this page and see your notes. There is no password on them. On a shared, work or public machine, treat this like a notepad left on a desk.

That is what the Delete all notes button is for. It wipes every note and clears the stored data from this browser in one go. It asks you to click twice, because there is no undo and no recycle bin.

How do I use it?

Just start typing. The first note is already open. The "Saved" label in the corner confirms each save.

Add a note with the New note button. Its title comes from your first line, so writing a heading names it for you.

Switch mode between Edit and Preview. Preview renders Markdown, so # Heading, **bold**, lists and code come out formatted.

Clean things up with Find and replace. It tells you how many matches exist before you replace them.

Write undisturbed with Focus mode, which hides the page and leaves only your text.

Take it with you using Copy text, Download .txt or Download .md.

What Markdown can I use?

A small, useful subset, the parts people actually type:

  • # through ###### for headings
  • **bold** and *italic*
  • `inline code` and triple-backtick blocks
  • - item for bullets, 1. item for numbers
  • > quoted line
  • --- for a horizontal rule
  • [text](https://example.com) for links

If you write plain text and never touch Preview, nothing changes. Markdown here is an option, not a format you are forced into.

When a notepad in the browser beats a real app

There is a specific moment this tool is built for: you need to put text somewhere right now. A code snippet from a call, a phone number, a draft message, a list before you forget it.

Opening a full note-taking app for that is friction: it wants an account, it syncs, it has workspaces and databases and templates. Powerful tools are powerful for long-term knowledge, but they are slow for a thirty-second thought.

This is the other end of that scale, on purpose. It opens faster than the app you were going to use, it asks nothing, and it remembers what you left in it.

What this tool does not do

  • It does not sync between devices. No account, no server, so a note on your laptop cannot appear on your phone.
  • It does not back anything up. If you clear your browser data, the notes go with it. Download what matters.
  • It does not share notes with other people. There is no link to send; copy the text or download the file.
  • It does not password-protect anything. Notes are readable by anyone on this browser profile. Use Delete all notes when you finish on a shared machine.
  • It is not a knowledge base. No folders, tags, backlinks or search across notes. It is a scratchpad, and it stays one on purpose.
  • It does not do rich text. No fonts, colours or images. Plain text with optional Markdown, which is what keeps it fast and portable.

Is my writing private?

Yes, completely. The notepad runs entirely in your browser. Your text is never uploaded, never logged, and never seen by anyone, including us. There is no request carrying your note content anywhere. Once the page has loaded, it works with no internet connection at all.

Frequently asked questions

Do I need an account to use it?

No. There is no sign-up, no login and no email to hand over. Open the page and start typing. Everything you write is kept in your own browser, so the tool works the moment it loads and keeps working offline afterwards. That is the whole point of a quick notepad.

Where exactly are my notes saved?

In your browser local storage, on the device you are using, and nowhere else. Nothing is uploaded to a server and nobody else can read it. That makes it private and instant, but it also means the notes live with that one browser rather than with your account.

Will my notes still be here tomorrow?

Yes, in the same browser on the same device, as long as you do not clear your browsing data. They survive closing the tab, closing the browser and restarting the computer. They will not survive clearing site data, using private mode, or switching to a different browser or phone.

Can I open my notes on my phone?

No, not the same ones. There is no sync, because there is no account and no server holding a copy. Notes written on your laptop stay on that laptop browser. If you need a note somewhere else, download it or copy the text and move it yourself.

Can I keep more than one note?

Yes. Click New note and it appears in the list on the left, with its title taken from your first line automatically. Switch between notes with a single click. There is no limit imposed by the tool, though very large amounts of text will eventually hit your browser own storage limit.

Does it support Markdown?

Yes. Write in plain Markdown and press Preview to see it rendered, with headings, bold, italic, links, lists, quotes, horizontal rules and code blocks. Switch back to Edit at any time. You can also download the note as a .md file to use it anywhere else that reads Markdown.

How do I find and replace text?

Open Find and replace, type what you are looking for and what should take its place, then use Replace all. The counter tells you how many matches there are before you commit. Searching is literal, so characters like a plus sign, a dollar sign or brackets are matched exactly as typed.

Can I get my text out of here?

Yes, in three ways: copy the whole note to your clipboard in one click, download it as a .txt file, or download it as a .md file if you wrote Markdown. Because notes are only stored in this browser, downloading anything important is the sensible habit to keep.

Can anyone else see what I write?

Nobody over the internet. Your text never leaves your device, so there is no server copy and nothing tied to your IP, and browser storage is locked to this one domain. The exception is local: anyone using the same browser profile on the same computer can open the page and read your notes.

How do I erase everything?

Use the Delete all notes button under the editor. It removes every note and clears the stored data from this browser in one action, and it asks for a second click first because there is no undo. That is the button to use before you walk away from a shared or public computer.
