* Add Tabs and Borders and Shading dialogs (#320) Tabs: lists the paragraph's tab stops with position, alignment and leader, Set / Clear / Clear All and the default interval. Opens from the Paragraph dialog's Tabs… button, by double-clicking a tab marker on the ruler, or para.tabs without params. OK is one para.tabs call, which now takes set / clear / clearAll / default (clearing a style's stop records a clear stop over it). Borders and Shading: Borders (None / Box / Shadow / 3-D / Custom, style, colour, width, paragraph or text, preview with clickable sides), Page Border (same, whole document or this section) and Shading (fill, paragraph or text) tabs. Opens from Home › Paragraph › Borders › Borders and Shading… and Design › Page Borders. OK runs only the changed parts as one undo step. para.borders and design.pageBorders take exact "sides" (and design.pageBorders a style and applyTo). Shadow and 3-D are drawn as heavier sides because the model has no border shadow flag; shading patterns are omitted because the model keeps a solid fill only. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Keep charts, SmartArt and OLE objects when saving DOCX (#319) Charts and SmartArt diagrams were drawn since #292 but the writer skipped them, and OLE objects kept only their picture, so opening and saving a document silently dropped them. The reader now keeps each object's own markup (the a:graphic of a chart or diagram, the whole w:object of an OLE object) on the model object, and every part it reaches through relationships (chart part, embedded workbook, colour and style parts; diagram data, layout, quick style, colours and drawing; OLE embedding and picture) as opaque bytes in Document::passthrough, with their content types and relationships in a manifest, as the VBA project already is. The writer emits the object with fresh relationship ids pointing at the re-added parts, keeping each part's own relationship ids and content types. A chart or diagram gets its frame from the object's current size and position; an OLE object gets its new size written into its VML shape. A part whose name the writer uses itself is renamed, and an object pasted more than once gets its own copies of every part (sharing past a size budget). Part counts, relationship counts, markup size and copy bytes are all capped.

OK is one layout.columns call, which now takes unequal widths and an apply target (forward adds a continuous section break first). Insert > Symbol > More Symbols... opens a Symbol dialog: font picker, Unicode subset list that jumps through a grid of only the characters the font has (drawn in that font), recently used symbols, a hex character code, and a Special Characters tab. insert.symbol takes a font for the symbol alone; typing after it goes on in the text's font. The ribbon's Symbol gallery shows recently used symbols first. Insert > Quick Parts > Field... opens a Field dialog: categories and the fields WordCraft computes, date pictures, number formats, bookmark / sequence / merge field names, preserve formatting, a live field code and a Field Codes view to type the code directly; OK runs insert.field. Also: date pictures read correctly when switches follow them, and am/pm and seconds work in date and time pictures. Strings in every catalog; gaps #7 and ui-parity updated.

WordCraft
Writing and document design; an open-source, clean-room reimplementation of Microsoft Word, rebuilt in pure Rust.
A fast, open-source word processor with the Word workflow you already know: the ribbon, styles,
tables, track changes, references and mail merge. It reads and writes .docx, runs natively on
macOS, Windows, Linux and BSD, and in the browser via WebAssembly.
By the ArtCraft team.
WordCraft on getartcraft.com · ArtCraft · All Crafting Apps
The Open Studio Handbook, WordCraft's built-in sample: the ribbon, live Styles gallery, rulers and the Navigation pane.
Note
ArtCraft is a community of artists from all walks of life. Painters, photographers, filmmakers, illustrators, designers, animators, hobbyists, and people who picked up a pencil last week. If you make things, you're one of us. Come say hi on Discord.

A tour
Every screenshot below is WordCraft itself, rendered offscreen by its own UI test harness
(cargo run -p wordcraft-ui-egui --example ui_shot).
 Review. Track changes, comment balloons in the margin, accept and reject, spelling and grammar as you type. |
 References. Tables of contents, footnotes, citations in APA, MLA, Chicago or IEEE, index and captions. |
 Design. Themes, style sets, paragraph spacing, watermarks, page colour and borders. |
 Dark mode with formatting marks, and the Insert tab: tables, pictures, shapes, links, headers, footers, fields and symbols. |
 Layout. Drop caps, text wrapping around pictures and shapes, automatic hyphenation, line numbers and page borders. |
|
 File. Start from a template, open recent documents, edit properties, export to PDF and other formats. |

Why WordCraft
- Familiar. Word's ribbon tabs, groups, shortcuts and behaviour: Enter continues a list, Tab demotes it, Ctrl/⌘+B bolds the word under the caret, the Styles gallery previews styles live, F4 repeats, F7 checks spelling, F8 extends the selection.
- Your files. Opens and saves .docx (OOXML), and also .odt, .rtf, .html, .md, .tex (LaTeX), .txt; opens Word 97-2003 .doc; exports PDF with real, selectable text, links and bookmarks.
- Fast. Paragraph layout is cached, so typing in a 188-page document re-lays it out in about 1.4 ms; pages render on demand.
- Everywhere. One Rust codebase for macOS, Windows, Linux, BSD and the web. No Electron, no Tauri: native egui on the GPU.
- Built for agents. Every action is a command with an id. The same 422 commands drive the ribbon, keyboard shortcuts, the command search, a command-line tool, a JSON control channel and an MCP server.
- Private. Spelling, grammar and everything else work offline.
- Open. MIT OR Apache-2.0. Clean-room: built from public specifications and observation, with every asset original or openly licensed.

Quick start
git clone https://github.com/storytold/wordcraft
cd wordcraft
cargo run --release -p wordcraft -- --sample # the desktop app with the sample document
cargo run --release -p wordcraft -- report.docx # open a document
Command line:
wordcraft-cli convert report.docx report.pdf # docx, pdf, odt, rtf, html, md, tex, txt, png
wordcraft-cli text report.docx # plain text
wordcraft-cli inspect report.docx # structure as JSON
wordcraft-cli run --template sample \
--cmd 'select.text={"text":"Membership"}' --cmd format.bold --save out.docx
Web: cd apps/wordcraft-web && trunk serve, then open http://127.0.0.1:8771/?sample.
For agents: CLI and MCP
WordCraft was designed to be driven by people and by AI agents.
claude mcp add wordcraft -- wordcraft-cli mcp # headless documents
wordcraft --control 7981 & # or drive the running app…
claude mcp add wordcraft-app -- wordcraft-cli mcp --connect 127.0.0.1:7981
Tools include list_commands, execute, batch, type_text, select_text, inspect_document,
render_page, save_document, and, with a running app, screenshot, click and key. Agents
can check their work through inspect_document without screenshots. See docs/mcp.md
and the control protocol. Macros record any sequence of commands and
play it back (tools.recordMacro, tools.macros).
Logs
The desktop app writes its log records to standard error and to logs/wordcraft.log next to its
preferences: on Linux $XDG_CONFIG_HOME/wordcraft/logs/ (by default ~/.config/wordcraft/logs/),
on macOS ~/Library/Application Support/WordCraft/logs/, on Windows %APPDATA%\WordCraft\logs\.
A start from a desktop menu or the Dock has no terminal, so this file is what to attach to a bug
report: unreadable parts of a .docx, pictures or fonts a PDF export had to leave out and panics the
command guard recovered from land there. Each launch moves the previous log to wordcraft.1.log
(and that one to wordcraft.2.log), so the log of a run that crashed survives the next start; a
log stops growing at 16 MiB. --version writes no file, and runs with WORDCRAFT_NO_PREFS (agents'
test runs) log to standard error only. Document text is never logged; a panic message leaves out
the text it quotes.
By default WordCraft's own crates log at info and everything else at warn. RUST_LOG replaces
that with env_logger-style directives, for example RUST_LOG=debug,
RUST_LOG=warn,wordcraft_docx=trace or RUST_LOG=info,wgpu_core=warn; a directive ending in *
covers every target starting with it (wordcraft*=debug). The logger is
apps/wordcraft/src/logging.rs.

Roadmap
WordCraft is in alpha. It covers 88% of Word's ribbon features with commands today; counting depth, file fidelity, stability and the rest, we estimate it is about 60% of the way to replacing all of Word for real work, about 55% for a typical professional's weekly work and about 63% for everyday essentials. Beta needs testing against real-world .docx files, keeping charts and SmartArt through a round trip, pagination closer to Word's, a stability sweep and native printing. Details and estimates: ROADMAP.md and where we fall short.

Installers and executables are code-signed.
If the app doesn't open on Windows: the desktop app initializes only DirectX 12 by default.
Letting wgpu also create an OpenGL instance can crash some graphics drivers (AMD's
atio6axx.dll) before the window appears, so the app would flash in Task Manager and quit.
WGPU_BACKEND overrides the default for troubleshooting (for example dx12 or vulkan). In
PowerShell, from the folder containing the executable:
$env:WGPU_BACKEND = "vulkan"
& .\wordcraft.exe
Remove-Item Env:WGPU_BACKEND # restore the default for later launches
An explicit gl override can bring the driver crash back on affected systems. The macOS, Linux
and web backend defaults are unchanged.
If the app is slow on an older Windows PC: when DirectX 12 finds no graphics card with a
driver for it (for example Intel 4th-generation graphics on Windows 11), it only offers Microsoft's
software renderer, which draws every frame on the processor. In that case WordCraft uses OpenGL
instead, without setting anything. The log file records the choice (lines starting with
graphics:). WGPU_BACKEND still overrides it, e.g. $env:WGPU_BACKEND = "gl" or "dx12".
