Is Office Word Editor free?

The editor itself is completely free. AI edits come with a free sponsored daily allowance for every visitor; beyond that, AI usage is billed per request through SkillSafe credits at cost-based prices, typically around a cent per edit.

Is my Word document uploaded to a server?

No. The .docx file is opened, edited, and saved entirely in your browser. Only the document content you send to the AI assistant (the text of your document plus your instruction) is transmitted to the AI model to compute the edit.

Can it edit an existing .docx file from Microsoft Word?

Yes. Open any .docx file: text, headings, formatting, lists, tables with shading, images, and hyperlinks are preserved. Page size, margins, headers and footers are kept when you download the edited copy.

Which AI models can I use?

GPT-5.6 Terra is the default. You can switch per request to other models including GPT-5.6 Sol and Luna, GPT-5.1, Claude Sonnet 5, Claude Opus 4.8, Claude Haiku 4.5, and Gemma 4.

Does the AI replace my whole document?

The assistant is instructed to preserve everything you did not ask it to change and to return the complete updated document. Every AI edit is applied as one undoable step, so you can always undo it.

Do I need an account?

No account is needed to edit documents or to try the AI within the free daily allowance. Sign in with SkillSafe to use the AI beyond the free allowance with your own credit balance.

Edit Word documents by chatting with an AI

Office Word Editor is a free, Word-style .docx editor in your browser with an AI assistant docked on the right. Type in the page like in Word — or tell the assistant what you want, and watch the document update. Your file never leaves your browser.

Start editing — it's free

Quick start

Open or create. Drag a .docx onto the page, use File > Open, or just start typing in the blank document.
Ask the assistant. Describe an edit in the chat panel — the AI reads the document, makes the change, and the page updates instantly. Every AI edit is one Undo step.
Download. File > Download a copy gives you a real .docx that opens in Microsoft Word, Google Docs, or LibreOffice.

What the AI assistant can do

Draft from scratch

Give it a topic and get a complete, structured document — title, headings, body, lists.

"Draft a one-page project status report for a website redesign"
"Write a formal complaint letter about a delayed delivery"
"Create a meeting agenda for a quarterly planning session"

Rewrite & polish

Improve what is already there without losing the rest of the document.

"Rewrite the introduction to be more concise"
"Fix grammar and improve clarity throughout"
"Make the tone more formal" / "friendlier"

Format & structure

It applies real Word styles — Title, Heading 1–3, Quote — plus colors, highlights, and alignment.

"Turn the bolded lines into Heading 2 sections"
"Add a title and organize this into sections with headings"
"Highlight every deadline in yellow"

Tables

Builds bordered tables with header rows and cell shading; edits existing ones.

"Add a summary table of the key points"
"Turn this list into a 3-column table: task, owner, due date"
"Add a row for October to the budget table"

Lists & layout

Real Word bullets and numbering (with nesting), page breaks, indentation.

"Convert the action items into a numbered list"
"Add a page break before the appendix"
"Group the risks into nested bullet points by severity"

Ask about the document

Questions get answers in chat — the document stays untouched.

"Summarize this contract in three sentences"
"What deadlines are mentioned in this document?"
"Is anything missing from this proposal?"

What a conversation looks like

What would you improve before I send it?

Consider adding a budget summary and naming a decision-maker for scope changes; everything else reads clearly.

Tips for good results

Be specific about scope. "Rewrite the second paragraph" beats "make it better". The assistant preserves everything you don't mention.
Chain edits. The assistant remembers the conversation, so "now make it shorter" works as a follow-up.
Mix manual and AI editing. Type and format directly in the page any time; the assistant always works on the latest state.
Use Undo freely. Every AI edit is one step in the app's undo history.
Switch models for the job. The dropdown in the chat header offers GPT-5.6 Terra (default), Claude, and cheaper models; the estimate under the input shows the reserved cost before you send.
