The Problem

You Bookmark Pages and Forget Why

Everyone has a bookmark folder full of links they never revisit because they have no idea why they saved them. The context is lost the moment you close the tab.

Note Apps Are Overkill

Notion, Evernote, OneNote — powerful tools, but they require accounts, folders, tags, and deliberate organization. For a quick thought about a website, they are too heavy.

Cloud Notes Come With Privacy Costs

Google Keep, Notion, and others sync your notes to their servers. Every thought you jot down passes through infrastructure you do not control.

Context Switching Kills Productivity

Alt-tabbing to a note app breaks your flow. The note should live where you are — inside the browser, attached to the page you are looking at.

The Solution

Per-URL Notes

Every Domain Gets Its Own Notebook

WebNotes Pro automatically loads the correct note when you visit any website. GitHub, Stack Overflow, YouTube, documentation, blogs — each one has its own private notepad. No folders to create. No tags to assign. It just works.

Auto-Save

Never Press Save Again

Your note saves itself 600 milliseconds after you stop typing. A green dot confirms it is saved; a pink pulsing dot means it is writing. You can also press Ctrl+S (Windows) or Cmd+S (Mac) for a manual save. Your thoughts are never lost.

Search All Notes

Find Anything Instantly

Open the All Notes panel to see every note you have ever written. Search by domain name, browse 80-character previews, and click any note to load it. A "Current" badge marks the site you are on so you always know which note belongs where.

Import / Export

Your Notes Are Portable

Export all notes as a single .wnb file, email it to yourself, and import it on another computer. The format is versioned, forward-compatible, and safe. Your notes are never locked into a proprietary system.

How It Works

Visit Any Website

Navigate to any URL — a documentation page, a forum thread, a news article. WebNotes Pro waits for you.

Click the Icon

Open the WebNotes Pro popup. A fresh notepad is ready, already linked to the domain you are on.

Type Your Note

Your note saves automatically. Revisit the same site later — your note is waiting, exactly where you left it.

Features

Per-URL Organization

Auto-Organized by Domain

Every hostname gets its own note. Visit stackoverflow.com — your Stack Overflow note loads. Visit github.com — your GitHub note loads. No folders, no tags, no manual sorting.

Auto-Save Engine

600ms Debounced Writing

Saves automatically after you stop typing. Zero performance impact. Visual indicators for save state. Manual Ctrl+S / Cmd+S fallback. Never lose a thought.

Glassmorphism UI

Modern Frosted-Glass Design

Clean, distraction-free writing area with backdrop blur, smooth animations, and polished transitions. Light theme and dark theme included — toggle with one click.

All Notes Manager

Search and Browse Everything

A bottom-sheet modal with real-time search by domain, 80-character previews, color-coded avatars, and instant load. Delete notes individually. The "Current" badge keeps you oriented.

Live Stats

Character and Word Count

See your character count and word count update in real time as you type. A "last saved" timestamp appears briefly after each save for confirmation.

Backup and Portability

Export / Import .wnb Files

Export all notes as a versioned, Base64-encoded JSON file. Import merges safely without overwriting existing notes. Cross-device portability — email the file to yourself.
