What is it?

You have six Notepad windows open. Meeting notes, a code snippet, a half-written email, some random thoughts. You need it all in one place — right now.

NoteStitch detects every open Notepad window, lets you pick which ones to include, and merges them into a single clean document with labeled sections. Copy it, save it, done.

Getting started

Install with winget

winget install BDvirus.NoteStitch

Fresh 1.0.14+ installs and upgrades use the standard Start-menu installer.

Upgrading from WinGet 1.0.13

Version 1.0.13 was a portable ZIP package, so this one-time move to the 1.0.14 installer requires a manual reinstall. Existing WinGet 1.0.13 users must run:

winget uninstall BDvirus.NoteStitch
winget install BDvirus.NoteStitch

Your settings in %AppData%\NoteStitch are preserved. After this one-time migration, fresh 1.0.14+ installs and upgrades use the Start-menu installer normally.

Install with a single command

Prefer not to use winget (or it hasn't propagated yet)? Paste this into PowerShell — it downloads and launches the latest Start-menu installer:

$i="$env:TEMP\NoteStitch-Setup.exe"; irm "https://github.com/BDvirus/NoteStitch/releases/latest/download/NoteStitch-Setup.exe" -OutFile $i; & $i

Download manually

Download NoteStitch-Setup.exe from Releases and run it to install NoteStitch on the Start menu. The accompanying NoteStitch.zip remains available for portable use.

Build from source

git clone https://github.com/your-username/NoteStitch.git
cd NoteStitch
dotnet publish NoteStitch/NoteStitch.csproj -c Release

Requires .NET 10 SDK and Windows.

Usage

1. Open some Notepad windows with content
2. Launch NoteStitch — it detects them automatically
3. Check the windows you want to include
4. Click Merge ▶
5. Copy to clipboard, save to file, or close the originals

Keyboard shortcut (optional)

Click ⌨ Shortcut… to register a Ctrl + Alt + ? global hotkey that launches NoteStitch from anywhere. Sign out and back in once for Windows to register it.

Technical notes

• Built on WinUI 3 / Windows App SDK (.NET 10) with a Mica-backdrop shell, NavigationView sidebar, and system-tray integration
• Uses SetWinEventHook (EVENT_OBJECT_SHOW, EVENT_OBJECT_DESTROY, EVENT_OBJECT_NAMECHANGE, EVENT_OBJECT_VALUECHANGE) to react to Notepad windows opening, closing, and being renamed — no polling loop
• On Windows 11 it reads every tab — including inactive ones — directly from Notepad's TabState binary files; on classic Notepad it falls back to WM_GETTEXT sent to the child Edit / RichEditD2DPT control
• Ships as a self-contained executable (win-x64) — the Windows App SDK runtime is bundled, nothing to install
