Getting Started

Install the anonym.legal add-in, sign in, and anonymize your first document in Microsoft Word in under 5 minutes.

1

Install the Add-in

There are two ways to install the anonym.legal add-in for Microsoft Word.

Option A: Microsoft AppSource

  1. 1.Open Microsoft Word
  2. 2.Go to Insert → My Add-ins → Store
  3. 3.Search for "anonym.legal"
  4. 4.Click Add to install

Option B: Sideload Manifest

  1. 1.Go to Insert → My Add-ins → Upload My Add-in
  2. 2.Enter the manifest URL:
https://anonym.legal/office_addin/manifest.xml

Sideloading is useful for testing or when AppSource is not available in your organization.

2

Sign In

After installation, the add-in panel appears on the right side of Word. Sign in with your anonym.legal account.

Zero-Knowledge Authentication: The add-in supports ZK auth. Your password is never sent to the server -- only a cryptographic proof. This means even we cannot see your credentials.

Don't have an account? Create one for free -- the free plan includes 200 credits per month.

3

Analyze Your Document

With a Word document open, click the Analyze button in the add-in panel. The add-in extracts the text and sends it to the anonym.legal API for PII detection.

  • Detects 285+ entity types (names, SSNs, credit cards, medical records, and more)
  • Supports 48 detection languages
  • Results appear in a list with entity types, values, and confidence scores

Review in Preview Window

Before applying changes, use the Preview Window to review exactly what will be changed. The Preview Window shows:

  • Side-by-side original and anonymized text
  • Method selector -- switch between Replace, Mask, Redact, Hash, or Encrypt
  • Language and preset selectors for quick adjustments
5

Choose Method and Apply

Select your preferred anonymization method and click Apply to modify the document.

ReplaceToken replacement

"John Smith" → "<PERSON_1>". Reversible with mapping file.

MaskPartial character masking

"john@example.com" → "j***@e******.com". Preserves format.

RedactPermanent removal

"John Smith" → "[REDACTED]". Irreversible, maximum privacy.

HashSHA-256 or SHA-512

"John Smith" → "a1b2c3d4...". Consistent across documents.

EncryptAES-256-GCM encryption

Fully reversible with the correct encryption key. Best for workflows requiring deanonymization.

Tips for First-Time Users

  • Use the Preview Window -- always review detected entities before applying. You can change the method, language, and preset from within the preview.
  • Ctrl+Z to undo -- if you apply anonymization and want to revert, use Word's standard Ctrl+Z (Cmd+Z on Mac) to undo the changes.
  • Save presets -- if you anonymize similar documents regularly, create a preset to save your entity selection, method, and operator configuration.
  • Preserve Formatting -- enable this option in settings to maintain bold, italic, and underline formatting when anonymizing.

Who built this

A small team of engineers and lawyers built this.

We ship from Europe and work in the open.

Our founder note spells out why we started.

Where to start

How the parts fit

A browser add-on cleans text inside Chrome.

A Word plug-in handles drafts in Office.

A small desktop tool works on whole folders.

An agent protocol link feeds large models safely.

All four share one core engine and one rule set.

Words from our team

We started this work after a lunch about cookies.

One friend kept getting odd ads on her phone.

We asked why a court file leaked through a draft.

We sketched the first build on a napkin that week.

By month three we had a tiny demo for a friend.

She used it on her first case the next day.

Common questions we hear

Can the tool read scanned PDFs? Yes, with OCR.

Does it work on long files? Yes, in small chunks.

Can I roll my own rule set? Yes, save it as a preset.

Does it run offline? The desktop build runs offline.

Do you keep my files? No, the cloud build wipes after each run.

Will it learn from my work? No, we never train on inputs.

A short tour of the workflow

Upload a file or paste a snippet of prose.

Pick the entities you want gone from the draft.

Choose a method: replace, mask, hash, encrypt, or redact.

Press run and watch the side panel show each hit.

Skim the result and tweak any rule that misfired.

Save the cleaned file or send it to a teammate.
