Markdown scratchpad
Write Markdown before your idea disappears.
ZeroNote is an online Markdown scratchpad for quick notes, snippets, prompts, checklists, and rough drafts. It opens fast, previews Markdown, and saves your text locally in this browser without an account.
Built for temporary Markdown, not heavy knowledge management
Use it when you need a clean Markdown buffer before text moves into GitHub, Notion, Slack, an email, a blog editor, or an AI chat.
Local autosave
Your drafts are saved with IndexedDB in the same browser profile, so the app stays useful even when you are offline.
Live preview
Write Markdown on the left and inspect the rendered result on the right before copying it elsewhere.
Common ways to use this Markdown scratchpad
- Draft README sections. Shape headings, bullet lists, code blocks, and links before pasting into a repository.
- Clean up AI prompts. Keep role, task, constraints, examples, and output format in a readable Markdown structure.
- Write quick publishing drafts. Prepare short posts, changelog notes, meeting summaries, or support replies without opening a heavy editor.
- Hold temporary snippets. Keep commands, Markdown tables, or copied text in one place while you work across tabs.
How it compares with bigger note apps
- Use ZeroNote when speed matters. It is a first-draft scratchpad, so it avoids workspaces, databases, sharing permissions, and setup screens.
- Use a knowledge base when permanence matters. If a note needs collaboration, backlinks, sync, or long-term organization, move it to your main system after drafting.
Local storage and privacy
Your Markdown stays in your browser. ZeroNote stores drafts locally with IndexedDB. Clearing site data, changing browser profiles, or switching devices can remove access, so download important notes as `.md` when they become worth keeping.
FAQ
Where is my data stored?
Notes are stored locally in your browser. Clearing site data or switching browsers can remove them, so download important drafts.
Is this a Notion or Obsidian replacement?
No. ZeroNote is a fast scratchpad for first drafts and temporary notes, not a long-term knowledge base.
Can I use it as an online Markdown editor?
Yes, for lightweight drafting and previewing. It is best for short to medium notes that you plan to copy, download, or move elsewhere.
Do I need to sign in to save Markdown notes?
No. Drafts autosave locally in the browser profile you are using, without a ZeroNote account.
