SiteNoteBox Extension – Your Notes, Organized by Website
SiteNoteBox is a free, privacy-focused browser extension that makes it easy to create, organize, and manage notes for any website you visit. Whether you want to save important information, keep track of website details, or organize your research, SiteNoteBox keeps everything in one convenient place.
Create notes for individual pages or entire websites, organize them into folders, add tags, and quickly access them through the browser popup or side panel. For sensitive information, SiteNoteBox also offers encrypted notes protected by a Master Password.
Everything stays on your device. SiteNoteBox works completely offline, requires no account or subscription, and never uploads your notes to external servers.
Designed for Google Chrome and compatible Chromium-based browsers, SiteNoteBox helps you stay organized without changing the websites you visit.
Smart Note Association: Site, Page & Global
SiteNoteBox lets you choose where each note belongs, so your information is always organized and easy to find. With three association options, you can attach notes to an entire website, a specific page, or keep them available across all websites.
- Site: Associate notes with an entire website. Access them from any page within that site.
- Page: Attach notes to a specific URL, keeping information relevant to that particular page.
- Global: Create general notes that aren’t tied to any website and can be accessed wherever you browse.
Switch between association types whenever needed and keep your notes connected to the right place.
Secure & Encrypted Notes
Keep sensitive information protected with SiteNoteBox’s Secure Notes feature. Unlike regular notes, secure notes are encrypted locally using AES-256-GCM encryption and can only be accessed after unlocking them with your Master Password.
- Strong Encryption: Protect sensitive notes with AES-256-GCM encryption before they are saved.
- Master Password: Keep your private notes locked and accessible only with your chosen password.
- Recovery Key: Regain access to encrypted notes if you forget your Master Password.
- Auto-Lock: Automatically lock secure notes after a period of inactivity.
- Offline Privacy: All encryption and decryption happen directly on your device, without sending information to external servers.
Secure Notes are completely optional, allowing you to use SiteNoteBox for everyday note-taking without entering a password. For confidential information, you can enable additional protection whenever you need it.
Organize Your Notes with Folders & Tags
Keep your notes organized and easy to find with SiteNoteBox’s flexible folder and tag system. Group related notes into folders, assign multiple tags, and manage your information across different websites.
- Custom Folders: Create folders to organize notes by project, topic, website, or any category you choose.
