CopyNote

A lightweight Windows tray utility for storing and instantly copying frequently used text snippets — emails, addresses, IDs, templates, and anything you paste often.

Русская версия / Russian version

Features

• One-click copy — click any entry to copy its value to the clipboard
• CRUD management — create, edit, delete entries
• Instant search — filter entries by label or value as you type
• System tray integration — lives in the notification area, slide-up/down animation on toggle
• Auto-hide on focus loss — click outside and the window quietly slides away
• Light & dark theme — follows system or manual override (Win11-inspired palette)
• Localization — English and Russian, auto-detected from system language
• Import / Export — backup all entries and settings to a single JSON file, restore with merge (deduplication by label+value)
• Autorun — optional start at Windows login (via Registry)
• Single instance — launching again brings the existing window to front
• Adaptive tray icon — auto-switches light/dark on theme change; pulse animation during startup
• Silent startup — no visible window or taskbar icon during WebView2 initialization
• Portable — single .exe, no installation required
• Lightweight — ~7 MB binary, ~40 MB RAM in idle

Requirements

• Windows 10 (1809+) or Windows 11
• WebView2 Runtime — pre-installed on Windows 11 and most up-to-date Windows 10 machines. If missing, download the Evergreen Bootstrapper.

Quick start

Download the latest copynote.exe from Releases and run it. That's it — no installer, no dependencies beyond WebView2.

The app starts minimized to the system tray. Left-click the tray icon to open.

Building from source

Prerequisites

Tool	Version
Go	1.23+
Node.js	18+ (only for building the frontend)

Steps

# 1. Clone
git clone https://github.com/DiHard/CopyNote.git
cd CopyNote

# 2. Build the frontend (Svelte + Tailwind → single inlined HTML)
cd web
npm install
npm run build
cd ..

# 3. Build the Go binary
go build -ldflags="-H=windowsgui -s -w" -o copynote.exe .

The resulting copynote.exe is fully self-contained (the frontend is embedded via //go:embed).

Regenerating the app icon

The tray/exe icon is generated from code (Lucide "copy" outline):

go run tools/genicon/main.go          # writes assets/icon-dark.ico + icon-light.ico
./bin/rsrc.exe -ico "assets/icon-dark.ico,assets/icon-light.ico" -arch amd64 -o resource_windows_amd64.syso

Data storage

What	Where
Entries	%APPDATA%\CopyNote\data.json
Settings	%APPDATA%\CopyNote\settings.json
WebView2 cache	%LOCALAPPDATA%\CopyNote\WebView2\

No data is stored next to the executable — safe to put it anywhere.

Tech stack

Frontend	Svelte 5, TypeScript, Tailwind CSS 4
