# Where WordCraft falls short of Word

> **Last reviewed:** 2026-10-10 · **Last updated:** 2026-10-11 · **Change:** trivial (Insert › SmartArt landed, #497; previously trivial: #24 narrowed: Customize Keyboard and Customize Ribbon landed; previously trivial: formatting revisions landed, #41; previously trivial: Draw Table and Eraser landed, #303; previously minor: beta distance restated: ~15 points, ~150–230 h; previously: first version; every known shortfall from the 2026-10-10 re-measure, ranked) · **Target:** Microsoft Word (Microsoft 365) for Mac 16.113.4

The work list. One entry per shortfall, ranked by how much it stops a Word user from switching
(**B** = blocks beta). Each says what's missing, the evidence, who it hurts, an Opus 5.5 agent
wall-clock estimate, and which parity document tracks it. Agents: pick from the top, check open PRs
first (`gh pr list`), and update this file and the parity doc when a gap closes.

## Ranked

| # | Gap | B | Evidence | Impact | Hours | Doc |
|---|---|---|---|---|---|---|
| 1 | **DOCX never tested on real-world files.** No corpus of files from Word, Google Docs, LibreOffice and Pages has been opened, rendered and round-tripped and compared with Word page by page | B | No corpus in the repo; `crates/docx/tests` are synthetic fixtures; "DOCX fidelity corpus: not started" since 2026-10-06 | Everyone: the files people receive are the files that break | 30–50 | [file-format-parity.md](file-format-parity.md) |
| 2 | **Ink and drawing canvases are dropped on open and lost on save, silently**; OLE objects show only their picture | B | No ink or drawing-canvas (`wpc`) handling in `crates/docx`; group shapes (`wpg`) read and written (#267). Charts and SmartArt are drawn (#292) and, with OLE objects, written back with all their parts on save (#319) | Documents with diagrams drawn in Word or pen notes lose content without warning | 4–8 to preserve ink and drawing canvases; 45–70 to render and edit charts and SmartArt (#13) | [file-format-parity.md](file-format-parity.md) |
| 3 | **Crashes and freezes in the field**: startup crash on Intel UHD Graphics (#170) (lag on GPUs without a DirectX 12 driver fixed, #316), freezes (#77, #59 Thai fonts, #31 font selector), no writes without admin on Windows 11 (#218), broken shape tool (#142), images can't be moved (#82) | B | 62 open issues, ~15 of them crashes, hangs or data-path failures | Anyone hit loses work or trust; the never-crash standard covers panics, not hangs or GPU driver faults | 20–30 | [target-app-parity.md](target-app-parity.md) (Stability) |
| 4 | **Pagination differs from Word**: Aptos has no metric-matched substitute; legacy compatibility options ignored; no page-by-page comparison harness | B | [layout-parity.md](layout-parity.md); [typing-parity.md](typing-parity.md) Known gaps | Page counts and line breaks differ, which matters for forms, legal and academic work | 30–50 + owner (font) | [layout-parity.md](layout-parity.md) |
| 5 | **Content controls** landed (#381): `w:sdt` kept, shown and edited (Developer tab, Design Mode, Properties). Move tracking landed (#400): `w:moveFrom`/`w:moveTo` with their named ranges round-trip, a tracked cut and paste of a paragraph or sentence records a move, either end accepts/rejects both, green double strike/underline markup and "Moved from/to" balloons; still missing: drag-and-drop moves (no text drag yet) and move options in Track Changes Options. Formatting revisions landed (#41): `w:rPrChange`/`w:pPrChange`/`w:tblPrChange`/`w:trPrChange`/`w:tcPrChange`/`w:sectPrChange`/`w:numberingChange` round-trip, are recorded while tracking, accepted/rejected and shown in balloons; still missing: tracked style-definition changes and table/section changes made in WordCraft | B | Issues #41, #400; source grep | Legal and editorial review workflows; templates with form controls | 5–8 | [file-format-parity.md](file-format-parity.md) |
| 6 | **No native printing** on desktop: File › Print opens the PDF in the system viewer, which prints (#286); no print dialog of our own (printer, copies, ranges); web prints through the browser (#209) | B | `ui.print` → `apps/wordcraft/src/print.rs`; issue #15 | Everyone who prints | 5–8 | [hardware-parity.md](hardware-parity.md) |
| 7 | **Dialog depth**: 54 modal dialogs vs Word's ~100 | B | `Dialog` enum in `crates/ui-egui/src/dialogs.rs` | Power users reach for dialogs the ribbon alone doesn't cover | 11–19 | [ui-parity.md](ui-parity.md) |
| 8 | **Proofing is English only**; no language per run, no dictionaries for other languages | | `crates/proof` has one dictionary; Word ships 120 proofing tools; issues #25, #40, #100 | Every non-English writer | 25–45 | [localization-parity.md](localization-parity.md) |
| 9 | **Password-protected files** can't be opened or saved | | #55; `docbin` detects and refuses RC4/XOR | Corporate and legal users | 6–10 | [file-format-parity.md](file-format-parity.md) |
| 10 | **Objects**: no group (#267 open), text in a freely rotated text box (free rotation and flips landed, #332; text direction, alignment and linked text boxes landed, #369; contour wrap and wrap side landed, #354), shape effects, WordArt 3-D effects and connector routing around shapes (WordArt effects and warps and glued connectors landed, #416), dragging members inside a Drawing Canvas (the canvas landed, #344) | | [parity-checklist.md](parity-checklist.md) (Shape Format 6/6, Layout › Group) | Newsletters, flyers, reports with diagrams | 20–30 | [target-app-parity.md](target-app-parity.md) |
| 11 | **Interface languages**: 8 of the 12 key languages missing (hi, ar, fr, id, de, ko, vi, pt-PT); no mirrored RTL interface; ~5% of strings still English in the six translated catalogs | | [localization-parity.md](localization-parity.md) | Most of the world's writers | 50–80 | [localization-parity.md](localization-parity.md) |
| 12 | **Draw tab / ink**: pens, pencil, highlighter, eraser, Select and Hide Ink landed (#307); Lasso Select, Add Pen, Ink to Shape and Ink Replay landed (#395); missing: Ink to Math, arrows in Ink to Shape, pressure, Word's own ink (`w14:contentPart`/InkML) | | [parity-checklist.md](parity-checklist.md) (Draw 9/11) | Pen and tablet users | 4–8 | [hardware-parity.md](hardware-parity.md) |
| 13 | **Charts and SmartArt editing** (editing charts and SmartArt from Word, more chart types and formatting) | | `insert.chart` and Chart Design basics landed (#409): WordCraft's own charts are editable; charts from Word stay read-only (no embedded-workbook editing), no combo/3D/radar/stock charts, axis or series formatting; Insert › SmartArt landed (#497) for graphics WordCraft makes | Reports and business documents | 35–55 | [target-app-parity.md](target-app-parity.md) |
| 14 | **`.doc` can't be written; metafile pictures and Word 6/95 files refused** | | `crates/docbin` is read-only | Users exchanging files with old Word or legacy systems | 25–40 | [file-format-parity.md](file-format-parity.md) |
| 15 | **References depth**: sources not saved in DOCX (#169 open); no EndNote/Mendeley desktop integration | | Sources live only in the session (#169 open) | Students and researchers | 6–10 | [target-app-parity.md](target-app-parity.md) |
| 16 | **Right-to-left completeness**: kashida, RTL in HTML/ODT/RTF; eight older RTL bug reports to re-verify after #207 (#215, #211, #199, #66, #63, #48, #19). RTL tables and sections landed (#362) | | [layout-parity.md](layout-parity.md) | Arabic, Persian, Hebrew writers | 7–11 | [layout-parity.md](layout-parity.md) |
| 17 | **East Asian typography**: Asian Typography options (Phonetic Guide landed, #288; Enclose Characters landed, #297; document grid landed, #391; vertical text landed, #491) | | Catalog misses `para.asianTypography` | Chinese, Japanese and Korean documents | 11–19 | [layout-parity.md](layout-parity.md) |
| 18 | **Screen-reader access** to the document canvas: exposed, not yet tried with real screen readers | | The canvas describes paragraphs, headings, lists, tables, links, pictures and the caret to AccessKit (#488), tested headlessly; no NVDA, VoiceOver or Orca run yet | Blind and low-vision users; public-sector procurement | 3–6 | [ui-parity.md](ui-parity.md) |
| 19 | **RTF and ODT depth**: notes, comments, revisions, sections, RTL | | ~1,500 lines each in `crates/formats` | Users exchanging with LibreOffice or older tools | 18–27 | [file-format-parity.md](file-format-parity.md) |
| 20 | **Performance on large real-world documents** unmeasured (500+ pages, many pictures) | | Only the 188-page sample benchmark | Thesis and book authors | 10–20 | [layout-parity.md](layout-parity.md) |
| 21 | **Mail merge data sources**: no Outlook/Contacts, Access or database sources, no email merge; CSV, typed lists (#247) and Excel/OpenDocument spreadsheets (#334) only | | Select Recipients reads .csv/.tsv, .xlsx/.xlsm and .ods | Office administrators | 4–8 | [target-app-parity.md](target-app-parity.md) |
| 22 | **Ecosystem**: no VBA execution (macros preserved only), no Office add-ins, no cloud storage, no real-time co-authoring | | `.docm` keeps macros (#172) | Enterprise users with macro templates; teams | 40–80 + owner decisions | [target-app-parity.md](target-app-parity.md) |
| 23 | **PDF Reflow** (open a PDF as an editable document, Word for Windows) | | | Users who edit PDFs they receive | 30–50 | [file-format-parity.md](file-format-parity.md) |
| 24 | **Default shortcuts**: ~135 of Word's ~250 (#330, #339, #343; Customize Keyboard #368, Customize Ribbon and the Quick Access Toolbar #379 landed) | | [ui-parity.md](ui-parity.md) | Power users | 4–7 | [ui-parity.md](ui-parity.md) |
| 25 | **In-app AI assistant** (Copilot-style draft, rewrite, summarize) | | Chat PR #178 open | Users expecting Copilot | 15–30 + owner (provider) | [target-app-parity.md](target-app-parity.md) |
| 26 | **Minor formats**: Flat OPC XML, Word 2003 XML, MHT, Works/WordPerfect | | | Rare | 20–35 | [file-format-parity.md](file-format-parity.md) |
| 27 | **View windows**: Side by Side, Synchronous Scrolling, Arrange All, Switch Windows | | [parity-checklist.md](parity-checklist.md) (View 25/29) | Comparing documents | 3–5 | [ui-parity.md](ui-parity.md) |
| 28 | **Dictate** | | `tools.dictate` missing | Dictation users | 8–15 + owner (speech model) | [hardware-parity.md](hardware-parity.md) |
| 29 | **Equations**: ink equations | | #191 notes; long display equations wrap at operators (#326) | Maths-heavy documents | 2–3 | [layout-parity.md](layout-parity.md) |

**Beta needs #1–#7** (~150–230 h with the stability and layout work they imply): they are the
blocking gaps, and closing them lifts file formats, layout, stability and UI enough to take the
full number from ~60% to ~75%. Everything else is depth on the way to full parity.

## By kind

The same gaps grouped the way the parity documents are, for agents working in one area.

- **Feature gaps:** #2 (preserve), #5, #10, #12, #13, #15, #17, #21, #25, #27, #28, #29; Clipboard
  pane, Manage Styles, Group (open PRs exist for the first three — review and merge before
  re-implementing). Paste Special, Advanced Find, Column Selection, Style Inspector, custom table
  styles, and Draw Table and Eraser (#303) landed on 2026-10-10.
- **UI/UX gaps:** #7, #18, #24; crop handles on the canvas (rotation handle landed, #332); table column drag on the
  ruler (#49, #217); context menus for objects and tables; Linux title bar theming (#78).
- **File-format gaps:** #1, #2, #5, #9, #14, #19, #23, #26; embedded fonts; glossary/building blocks.
- **Hardware gaps:** #6, #12, #28; scanner/Continuity Camera insert; KDE soft text (#140).
- **Localization gaps:** #8, #11, #16, #17; native-speaker review of every catalog (human).
- **Stability and performance gaps:** #3, #20.
