Privacy and security
This is a privacy-first secure online notepad. By default, every note lives in your browser local storage. We do not run user accounts and do not transmit your text to any server. For sensitive content, the optional password lock hashes your password with SHA-256 directly in your browser, so even we cannot see it.
AI assistant
The optional AI assistant inside the free online notepad can summarise long notes, rewrite paragraphs in a different tone and brainstorm bullet lists. The editor remains a fully working online notepad even with the AI panel closed.
How auto save works
This online notepad with auto save uses a debounced writer to persist your changes to local storage roughly once per second. There is no Save button to click. Closing the tab or the browser will not lose your notes — they reload exactly as you left them.
Browser local storage explained
Local storage is a small private database built into your browser. Notes from this online notepad are scoped to this site only and to the device you are using. To move notes between devices, use the export feature to download a JSON backup and import it elsewhere.
