Docs

Edit .docx documents in your browser without uploading them

Vault Studio Pro Docs opens, edits and saves .docx files entirely inside your browser tab. Your document is read from your disk, edited in memory and written back to your disk. It is never sent to our server.

What the document editor does

Docs is a word processor for everyday writing: letters, reports, proposals, meeting notes and CVs. It reads .docx files, the format used by Microsoft Word, Google Docs exports and LibreOffice, and it saves genuine .docx files that those programs can open. Everything happens in the page you have open. There is no conversion server and no account.

How to edit a .docx file

  1. Open the app and choose Docs, or drag a .docx file anywhere onto the app window.
  2. Edit the text with the toolbar or the usual keyboard shortcuts.
  3. Press Ctrl+S (Cmd+S on a Mac) to save a .docx copy to your computer, or use the export menu for PDF or Markdown.

While you work, the app keeps a draft in your browser's own storage on this device, so a refresh or a closed tab doesn't lose your work. That storage is not encrypted, so on a shared computer export your file and clear the project when you are done.

Writing and formatting

  • Fonts and sizes, bold, italic, underline, strikethrough, text colour, highlight, subscript and superscript.
  • Headings, quotes, callout boxes, code blocks, dividers, bullet and numbered lists, and tick-box checklists.
  • Alignment, line spacing, margins, columns, a page border, A4 or US Letter paper, and a watermark.
  • Tables with borders and shading, plus page breaks and an automatic table of contents.
  • Find and replace, an outline sidebar, and live word, character and reading-time counts.

Reviewing and collaborating on your own copy

Docs includes threaded comments and a suggestion mode that records insertions and deletions so you can accept or reject each change, or all of them at once. Pro adds revision history: snapshots of your document that you can roll back to. Because nothing is stored on a server, there is no real-time co-editing. To share a document you send the file itself.

Extras

  • Equations written in a subset of LaTeX (fractions, roots, Greek letters, operators).
  • QR codes and Code-128 barcodes, generated on your device.
  • Three starter templates: a resume, a client proposal and meeting notes.
  • An image signature stamp you can draw, type or upload. It is a picture of a signature, not a cryptographic digital signature.
  • Read aloud, which uses your browser's built-in speech voices.

Dictation is the one feature that can leave your device. It uses your browser's speech recognition service. Chrome sends the audio to Google, and Safari sends it to Apple. The app asks before it starts, and dictation currently understands English (US) only.

Limits worth knowing

  • Opening a .docx converts it to an editable web document. Headings, lists, tables, links and images carry over, and table borders, cell shading, column widths and page borders are restored. Headers and footers, exact fonts and colours, text boxes and tracked changes made in another program may be simplified or dropped. Keep your original file until you have checked the result.
  • PDF export is an image of each page, so the text in that PDF can't be selected or searched. For a text PDF, save as .docx and print to PDF from your system, or use the print option.
  • There is no real-time collaboration, cloud sync or mail merge.

Who it's for

Docs suits anyone who needs to edit a .docx on a computer where they can't or don't want to install software, and anyone whose documents shouldn't go through a third-party upload service: contracts, HR letters, medical or legal notes, drafts under embargo. If you depend on complex Word layouts, macros or co-authoring, a full desktop word processor is the better fit.
