Inklet

Status: released and actively developed · Latest: v1.0.9 · Requires: Windows 10 1809 (build 17763) or later

A lightweight, modern Notepad clone for Windows built with WinUI 3 and .NET 8.

Inklet faithfully recreates the classic Windows 10 Notepad experience with modern WinUI 3 styling, Mica backdrop, and system theme support — while staying as light and fast as possible.

Download

Tabs & Session

• Multi-tab editing — Any number of tabs open simultaneously
• Session persistence — All tab content, cursor position, encoding, and line endings are automatically saved on close and restored on next launch (including unsaved content in untitled tabs)
• Tab headers — * prefix indicates unsaved changes

Format

• Word Wrap — Toggle word wrap on/off
• Font — Choose font family, style, and size

View

• Status Bar — Line/column position, encoding, line ending, zoom level
• Zoom — Ctrl+Scroll, Ctrl+Plus/Minus, or View › Zoom menu (25%–500%)

Encoding Support

• UTF-8 (with and without BOM)
• UTF-16 LE / BE
• ANSI (system default)
• Auto-detection of file encoding including international code pages
• Extensive code page support (Shift-JIS, GB2312, ISO-8859-x, and more)

Line Endings

• Windows (CRLF)
• Unix (LF)
• Classic Mac (CR)
• Automatic detection and display in status bar

Performance

• Instant startup

• Documents of any length — a custom Win2D editor draws only the lines visible in the viewport, so files of any size display in full and stay responsive (the built-in WinUI text controls stop rendering large documents)

• Responsive typing in large files — the editor never re-serialises the whole document on a keystroke; the cached copy is refreshed only when needed (save, find, go to)

• Minimal memory footprint

• Mica backdrop behind the title bar and tabs

• IME (East-Asian composition) input via CoreTextEditContext, so an active IME composes and commits inline at the caret

Not yet implemented on the new editor surface: screen-reader (UIA) accessibility — a planned follow-up.

File Associations

• Registers as an "Open With" handler for common text formats: .txt, .log, .ini, .cfg, .md, .xml, .json, .csv, .yaml, .yml

Requirements

• Windows 10 version 1809 (build 17763) or later
• Windows 11 supported
