Quick Notes
A browser-local Markdown scratchpad. Write, click to render, autosaved as you type, never uploaded.
How to use Quick Notes
Quick Notes is a no-frills Markdown scratchpad that lives in your browser tab. Type anything — meeting notes, a URL, a code snippet, a phone number someone just dictated — and it stays there, autosaved to this device’s local storage. Click away from the editor (or press Escape) and your Markdown renders into a clean formatted view; click back in to keep writing. There is no account, no sync, and nothing ever leaves your machine.
- 01Just start typing. The editor accepts plain text and GitHub-Flavored Markdown — headings, bold and italic, lists, task lists, fenced code blocks, blockquotes, links and tables.
- 02Click outside the textarea or press Escape, and your Markdown renders into a clean formatted view. The HTML is produced locally with marked and sanitized with DOMPurify, so scripts and inline event handlers are stripped before display. Click the rendered view to drop back into editing.
- 03Every keystroke is autosaved to your browser’s localStorage instantly. Close the tab, restart your computer, come back next week — your note will still be here on this device.
- 04To take the note elsewhere, use copy for the clipboard or download .md for a Markdown file you can keep or move to another machine.
- 05Use clear to wipe the note. It asks for a second click within four seconds, so an accidental click won’t destroy your scratchpad.
tips
- —Good fits: meeting minutes in Markdown, draft replies, README fragments, API keys you need to paste once, a running to-do list with task-list checkboxes (
- [ ]). - —Notes do not sync across devices — they’re pinned to this browser. To move them, download the .md file and open it elsewhere.
- —Clearing your browser data or using a private/incognito window will erase the note. Export anything you want to keep before doing that.
- —It’s fine for throwaway secrets, but for long-term credentials use a real password manager — anything in localStorage is readable by other scripts on this site.
frequently asked
Where are my notes stored?+
Entirely in your browser via localStorage. Every keystroke is written to a local storage slot on this device. The notes are never sent to any server — there is no account, no sync, no upload. If you clear your browser storage or use private/incognito mode, the notes will be gone.
Does it support Markdown?+
Yes. The editor uses GitHub-Flavored Markdown — headings, bold/italic, lists, task lists, fenced code blocks, blockquotes, links and tables. Click out of the textarea (or press Escape) and your note renders into a clean formatted view; click back in to keep writing. The rendered HTML is sanitized with DOMPurify to strip scripts and event handlers.
How is this different from the Markdown Preview tool?+
Markdown Preview is a one-off renderer: paste text, see HTML, nothing is kept. Quick Notes is a persistent notebook — everything you type is autosaved to this browser so it’s still here when you come back. Use Quick Notes for things you want to keep, Markdown Preview for quick throwaway rendering.
Will my notes sync across devices?+
No. Because the data lives only in this browser’s localStorage, it stays on this device. To move notes to another machine, use the Download .md button and open the file there, or copy the text manually.
How much can I store?+
Browsers typically allow 5–10 MB per site in localStorage, which is roughly a few hundred thousand words — more than enough for a scratchpad. If you ever hit the limit (very rare), older saves simply stop updating and the latest change won’t persist.
Is it safe to paste sensitive things like passwords or API keys?+
Safer than pasting into a tool that uploads to a server, because nothing leaves your device. Still, localStorage is readable by any script on this exact origin, so for long-term secrets use a dedicated password manager instead of a temporary scratchpad.
