About LawRedact

LawRedact is an offline AI redaction platform for counsel, in-house legal, compliance, and case teams — Windows / macOS desktop plus Android / iOS / HarmonyOS mobile, sharing one on-device recognition core.

When sharing materials externally, filing with a court, feeding an LLM, or collaborating across teams, you routinely need to redact names, ID numbers, contact details, account numbers, case numbers, and similar fields. Manual find-and-mask is slow, error-prone, and hard to standardise, with little audit trail; online tools raise confidentiality, NDAs, and air-gapped-network concerns.

LawRedact detects and redacts entirely on-device: the legal-tuned LROLMLL 2.1 model (99.73% F1) plus OCR, working with a rule engine across 45 sensitive entity types; four strategies — pseudonym, asterisk, colour mask, and strict delete — configurable per entity. Models ship with the installer; source files are not uploaded; works offline and in isolated networks.

Desktop is the primary workstation: Word / PDF / Excel, folder batch, quality scoring, leak alerts, redaction templates, case-level shared pseudonyms, and encrypted reversible restore — for case bundles, formal outbound, and archival traceability. Licensed full mobile on Android / HarmonyOS; permanent free Lite on the App Store for iOS. All suit travel, on-site capture, and quick single-file work. Desktop licenses include one Android / HarmonyOS seat so office and field workflows stay aligned.

Why teams choose LawRedact

On-device · data stays yours

Models run locally with outbound networking blocked during processing — suited to privileged matters, air-gapped sites, and cross-border data controls.

Legal-focused · 45 entity types

Tuned for contracts, judgments, pleadings, and evidence — 45 entity types including names, organisations, IDs, accounts, amounts, case numbers, seals; documents in zh / en / ja / ko.

Flexible strategies · review-ready

Four redaction modes per entity type; desktop adds quality scoring, leak alerts, manual review, and operation history before anything leaves the firm.

Desktop + mobile · clear roles

Desktop handles batch, Excel, templates, and reversible restore; mobile handles capture, quick redaction, and pre-send checks — same core, consistent results.

Mobile: role and capabilities

Redact before you send

Recognition and masking run on the device — no cloud API. Offline guidance and self-check live under Profile.

Same core as desktop

Shared 45-type engine so field work matches office policy without re-tuning strategies.

Four modes on the preview screen

Pseudonym, asterisk, colour mask, or strict delete — mask colour configurable for each recipient.

Capture in the field

Local files, downloads, clipboard, system share; camera scan and screenshot flows for chat logs, IDs, and screen evidence.

Perpetual license with one year of free updates from first activation. The sections below cover scenarios, activation, how-to steps, outbound checks, and FAQ. Press F1 on desktop for UI-level guidance.

When to use it

LawRedact detects and redacts on your device — case files are not uploaded. Below: common timing, then industry/material scenarios (aligned with the homepage audience section).

When it helps

Before AI or an assistant

Pseudonymize or mask locally, then share the export with an LLM or internal assistant.

Outside counsel, auditors, partners

Control IDs, accounts, and contacts by field while keeping clauses readable.

Public or web-facing drafts

Strict-delete or color-mask identifiers, then human-check layout before release.

Chat logs and payment screenshots

OCR marks candidates; finish with manual boxes for field evidence.

Industries & materials

Match redaction policy to your material type. Full 45-type catalog is under Detection in the sidebar.

Process your first file

On a computer, a typical pass looks like the steps below. Mobile is shorter, with the same order: detect, review, redact, export.

1

Import

Add Word, PDF, Excel, images—or a whole folder on desktop.

Scans use OCR and take longer; see Files & performance.

2

Detect

On-device model marks candidates. Picking a material type (contract, judgment) usually helps.

3

Review

Remove false hits, add misses. Desktop shows quality score and leak hints.

Aim for score 90+ before formal outbound.

4

Choose redaction

Pick mode per field, or start from a template and tweak.

5

Preview and export

Check layout, then save. Export a process report when you need a trail.

On mobile: open or photograph → detect → adjust → export/share. For formal filing, re-check on desktop.

What it detects

LawRedact detects 45 sensitive types on-device, with zh/en/ja/ko and automatic language detection where possible. Always review before outbound.

On import you can choose a material type—such as judgments, pleadings, contracts, official letters, chat screenshots, or payment vouchers—to improve detection accuracy.

Choose a redaction mode

Match the destination first, then tune per field. Modes can mix in one document.

Mode

Pseudonym

Best for

LLM analysis, readable internal review

Less ideal for

Public drafts that must be unreadable

Mode

Asterisk

Best for

In-firm circulation with light context

Less ideal for

Strong external anonymity

Mode

Color mask

Best for

PDF/image outbound, block copy

Less ideal for

Text analysis by an LLM

Mode

Strict delete

Best for

Public/web, highest sensitivity

Less ideal for

When context must stay readable

Pseudonym

Consistent placeholders for the same entity in one file.

John Smith → Person 1

Asterisk

Partial masking with light remaining clues.

张三 → 张**

Color mask

Paint over regions; originals cannot be copied after masking.

6222 0000 → ████ ████

Strict delete

Remove content; irreversible after deletion.

18100000000 → (removed)

Desktop redaction templates

Court Filing

Higher intensity for filing and publication-related packs

Finance Review

Focuses on accounts and amounts

Internal Archive

In-firm retention; readability first

Names Only

Focuses on person names

Public Release

Highest intensity; leans delete or mask

Apply a template in one click, then adjust by entity type if needed. With reversible mode on desktop, an encrypted .maskmap is exported. Restore needs both map and password within authorization. Public or strict-delete policies are irreversible. Store maps separately from outbound copies.

Desktop hardware tips

  • RAM: 8 GB minimum; 16 GB+ for frequent scans or batches
  • Disk: ≥ 2 GB free; SSD preferred
  • CPU: fine for Word / text PDF; OCR leans on CPU
Scanned PDFs and images run page-by-page OCR. On tighter machines, convert to editable text first. Normal Word or text-layer PDFs are usually fine.

Before you send

Before export, confirm the recipient, redaction strength, and leftover file traces.

Align what the recipient may see

Internal review, LLM, outside counsel, and public posting need different strength.

Review formal work on desktop

Use quality score and leak hints. Aim for 90+ before export.

Check leftover traces

Comments, tracked changes, and hidden text can remain in exports.

Keep reversible files separate

Do not store maps and passwords next to the outbound redacted copy.

Pre-send checklist

  • Recipient and allowed fields are clear
  • Human review done (especially court / regulator / public)
  • Comments or tracked changes removed from export
  • Reversible maps stored under separate controls
  • Mobile quick passes re-checked on desktop for filing
Using this software does not replace your duty of confidentiality or your judgment on compliance for each matter.
