Loupe in Word
The add-in opens a pane beside your document. Press Check the document, or select a passage and check only that. Click a finding to go to the citation in the text.
- Adding it. Loupe is not in Microsoft's add-in store yet, so it is installed from a file; the steps for each kind of Word are below.
- Opening it. Loupe appears on the Home tab.
- Removing it. See the end of each set of steps below.
Install the Word add-in yourself
Download the add-in file loupe-word-add-in.xml
The file is a few lines telling Word where Loupe's pane lives; it is not a program. Then follow the steps for the Word you use.
Word in a browser
- Open a document in Word at office.com.
- Choose Home, then Add-ins, then More Settings.
- In the Office Add-ins window, choose Upload My Add-in, then Browse, pick the file you downloaded, and choose Upload.
- Loupe appears on the Home tab.
Word keeps an add-in added this way in that browser only. In another browser, or after clearing the browser's data, upload the file again. To remove it, clear the browser's data for office.com.
Word on a Mac
- In Finder, press Cmd+Shift+G and go to
~/Library/Containers/com.microsoft.Word/Data/Documents/wef. If the folderwefis not there, create it. - Copy the file you downloaded into that folder.
- Open Word, or quit and reopen it, and open a document.
- Choose Home, then Add-ins, and pick Loupe.
To remove it, delete the file from that folder and reopen Word.
Word on Windows
If you, or your firm, manage your own Microsoft 365, the simplest way is the one for a whole firm, below, with Just me chosen. To install it on one computer by hand:
- Make a folder, for example
C:\Loupe, and copy the file you downloaded into it. - Right-click the folder, choose Properties, open Sharing, choose Share, add
yourself, and choose Share. Note the network path it shows, such as
\\YOUR-PC\Loupe. - In Word, choose File, Options, Trust Center, Trust Center Settings, then Trusted Add-in Catalogs.
- Enter the network path under Catalog Url, choose Add catalog, tick Show in Menu, and choose OK twice. Close Word and open it again.
- Choose Home, then Add-ins, then Advanced. Open Shared Folder, select Loupe, and choose Add.
Microsoft describes this route as meant for testing, and it works on Windows only. To remove it, delete the file from the folder and remove the catalog in the same Trust Center page.
For everyone at a firm
A Microsoft 365 administrator installs Loupe for every user, or for chosen ones, in Word on Windows, on a Mac and in the browser at once. Nobody else does anything.
- Sign in to the Microsoft 365 admin center.
- Choose Show all, then Settings, then Integrated apps, then the Add-ins link near the top, then Deploy Add-in and Next.
- Choose to upload a custom add-in, choose the option to give a URL for the manifest, enter
https://loupe.legal/manifest.xml, and choose Upload. - Choose Everyone, Specific users/groups or Just me, then Deploy.
Microsoft says an add-in deployed this way can take 24 to 72 hours to appear on the ribbon, and people may need to reopen Word. To remove it, remove it on the same Add-ins page.
What the add-in sends
When you press Check, the text of the document, or of your selection, goes to loupe.legal and is checked there. It is not kept. The add-in changes nothing in the document; it selects a citation when you click a finding. See Privacy for the whole of what we hold.
If a check does not run
- The daily allowance. Without an account, Loupe checks ten documents a day from one network. The pane says so when they are used; the count starts again at midnight UTC.
- A lookup that did not answer. Loupe says "not checked" rather than guessing. Check again later, or check that citation yourself.
- Nothing happens in Word. Close the pane and open it again. If it still does nothing, write to us with your Word version and what you see.
Loupe in Claude and ChatGPT
Loupe connects to an assistant so that it can check the authorities in what it writes, or in
text you give it. You sign in to Loupe and allow it; the assistant never sees your sign-in.
The address is https://loupe.legal/mcp.
In Claude
- Open Customize, then Connectors.
- Press Add, then Add custom connector.
- Name it Loupe, enter
https://loupe.legal/mcp, press Continue, then Add. - Press Connect, sign in to Loupe and press Allow.
- In a conversation, press +, then Connectors, and check that Loupe is on.
On Team and Enterprise plans an owner adds Loupe once in the organisation's settings, and everyone else presses Connect. Claude Code connects to the same address.
In ChatGPT
- Open Loupe Citation Checker in ChatGPT's plugins and press Install plugin.
- Checking a draft, a citation or a case name works at once, without an account. A quotation checked against the opinion, and a signed record, ask you to sign in to Loupe and press Allow.
- In a conversation, add it from the tools menu.
The server can also be added by hand: on the web, open Settings, then
Security and login, turn on Developer mode and read its warning; open Plugins,
press +, name it Loupe and enter https://loupe.legal/mcp. Developer mode needs a
Plus, Pro, Business, Enterprise or Education plan, and is on the web rather than the phone. These menus
have moved before; if yours look different, OpenAI's help pages have the current path.
What it can do
| Tool | What it does | Who |
|---|---|---|
| Check a legal draft | Checks every authority and link in a passage, and says which checks ran and which did not. Reads only. | Anyone |
| Check one citation | Whether a citation exists, whether it is the case the text names, and whether its page falls inside the opinion. Reads only. | Anyone |
| Find a case by name | The cases Loupe holds under that name, with their citations. Reads only. | Anyone |
| Verify a quotation | Whether the quoted words are in the opinion they are attributed to, and whose words they are. Reads only. | Signed in |
| Evidence bundle for a draft | A sealed record of a check, kept in your Loupe account. Each call adds one record and changes nothing else. | Signed in |
Checks made through an assistant count toward your account's daily allowance, as checks on the site do.
What it sends, and what is kept
- The assistant sends Loupe only the text it asks about. Loupe checks it and does not keep it.
- An evidence bundle is kept in your account until you delete it.
- Loupe does not read your conversations, your files, or anything else in the assistant.
Taking access back
Your account page lists every assistant you allowed, under Assistants you allowed. Removing one stops it at once. You can also disconnect Loupe in the assistant's own settings.
If it does not connect
- It asks you to sign in again. Allowing an assistant needs a recent sign-in, since it keeps its access afterwards. Sign in on the page it opens.
- "Not an address Loupe knows". The page that asks you to allow it says so when the answer would go somewhere other than Claude, ChatGPT or an application on your computer. Press No unless you started that connection yourself.
- Anything else. Write to hello@loupe.legal with what the assistant showed.
Your account and your data
Your account page lists the checks you kept, downloads what we hold and deletes the account. Questions about personal data go to privacy@loupe.legal.
