Doclight

A lightweight, minimal local document editor for Windows.

Open a document, read it, edit text with basic formatting, copy and paste, and save it. No accounts, no cloud, no ribbon. It is not meant to replace Microsoft Word.

The app interface is currently in Spanish.

Features

• Opens and saves .docx, .txt and .md
• Headings (H1–H3), bold, italic, underline, lists, alignment and links
• Clean pasting from web pages and chat assistants
• Find in document
• Light and dark themes
• Zoom
• Registers itself under Open with for .docx, .txt and .md, and can be set as the default app from Windows

.docx limitations

Word compatibility is intentionally basic:

• Paragraphs, H1–H3, bold, italic, underline, lists, alignment and links are preserved.
• Images, tables, headers, footers, comments, complex styles, columns and tracked changes are not imported or exported.
• Re-saving a .docx created in Word simplifies it to the subset Doclight understands.
• Underline works fine inside Doclight, but may be lost when exporting to .docx in some cases (mostly inside lists). Bold, italic, headings, lists and links are kept.

Architecture

• src/editor — Tiptap / ProseMirror editor
• src/files — opening, saving and converting formats
• src/components — user interface
• src-tauri — native window, file associations and local file I/O
