Your document, read and rewritten without leaving Word
The HiloIntelligence pane opens inside Word and works on the open document: it reads what you point it at, writes, formats, handles comments and tracked changes. Nothing is uploaded automatically — the assistant reads what it asks for, when it needs it.
An assistant that genuinely handles the document
Not a chat beside your text: the pane acts on the document, with tools that match what Word can actually do.
Read what matters
The selection, a section found by its heading, the outline, footnotes, headers and footers, tables or fields — the assistant asks for what it needs instead of swallowing the file.
Write and format
Insert and replace text, apply fonts, styles, alignment and line spacing, create tables, insert notes, bookmarks, fields (table of contents, page numbers, cross-references) and images.
Work in review
Add a comment anchored to a passage, read and reply to existing threads, turn on tracked changes, then accept or reject revisions.
Suggest rather than impose
In “Suggest before applying” mode, every edit arrives as a native tracked change, to accept or reject from Word's Review tab.
Step back
Before the first write of a turn the pane snapshots the document and can restore it — and tells you plainly when the snapshot could not be taken.
Cite and take you there
Short quoted passages in the answer are clickable: one click moves Word's selection to that exact spot in the document.
Deployed by your administrators, not installed by hand
The add-in is deployed by manifest URL from the Microsoft 365 admin center, then assigned to a group.
- 01
Word on Windows, Mac and the web
The manifest declares the desktop form factor; Word on the web is supported and needs one extra redirect URI in Entra for single sign-on. Older Word builds simply expose fewer tools, without errors.
- 02
One admin-center deployment
Your administrators paste the manifest URL into Integrated apps, then assign it to a group rather than to everyone. Allow 24 to 72 hours for Microsoft-side propagation.
- 03
The same app registration as Outlook
The Word add-in reuses the Entra registration already in place for the Outlook add-in — nothing new to create on your tenant, apart from the redirect URI for web use.
- 04
Access stays yours
Sign-in uses the person's Microsoft single sign-on, and your administrators decide which groups may use the module.
What the add-in does not do
Word's add-in API does not expose everything, and the assistant is built to say so rather than improvise.
- Page setup (margins, orientation, size, columns), document themes, floating images and text wrap: out of the API's reach.
- Shapes, text boxes, SmartArt and equations, mail merge and macros, the bibliography source manager, document compare and protection, spell-check results: not supported.
- Custom styles are available on the desktop, but not in Word on the web.
- Two tools send the whole document to your own server: conversion to formatted markdown, and rendering a page as an image. Every other tool sends only what it reads.
- Undo restores the document body as it was at the start of the turn, formatting included — but it is not Word's Ctrl+Z: it is a snapshot the add-in takes, and it tells you when it could not be captured. One exception: in Word on the web, restoring fails when the file is hosted by a third party such as Dropbox or NetDocuments (SharePoint, OneDrive and the desktop are unaffected).
- By default edits apply immediately. Turn on “Suggest before applying”, or turn off auto-apply, to confirm each change.
Getting the Word add-in to your teams
Four steps, done once by your Microsoft 365 administrators. Nothing to install on anyone's machine.
- 1
Copy the manifest URL
It is shown inside your instance under Admin → Settings, with a copy button. It ends in /word/manifest.xml.
- 2
Open Integrated apps
In the Microsoft 365 admin center: Settings → Integrated apps → Upload custom apps, then “Provide a URL for the manifest”.
- 3
Assign to a group
Rather than to everyone — that is what lets you open the add-in to a pilot team before widening it.
- 4
Let Microsoft propagate
Allow 24 to 72 hours before the button appears in everyone's ribbon. The delay is Microsoft's, not the platform's.
Each add-in deploys separately. For use in Word on the web, a redirect URI must also be added to your Entra app registration — without it single sign-on fails in the browser while the desktop works. Our team supplies it with the manifest.
Try it on your own files
Create your workspace and deploy the add-in from the Microsoft 365 admin center. Your administrators choose who gets access.
